Exploring the utility of ultrasound to assess disuse atrophy in different muscles of the lower leg.BACKGROUND: Skeletal muscle is a highly plastic tissue crucial for many functions associated with whole-body health across the life course. Magnetic resonance imaging (MRI) is the current gold standard for measuring skeletal muscle size. However, MRI is expensive, and access to facilities is often limited. B-mode ultrasonography (U/S) has been proposed as a potential alternative to MRI for the assessment of muscle size. However, to date, no work has explored the utility of U/S to assess disuse muscle atrophy (DMA) across muscles with different atrophy susceptibility profiles, an omission which may limit the clinical application of previous work. METHODS: To address this significant knowledge gap, 10 young men (22 ± years, 24.1 ± 2.3 kg/m2) underwent 15-day unilateral leg immobilization using a knee-brace and air boot. Cross-sectional area (CSA) and muscle thickness (MT) of the tibialis anterior (TA) and medial gastrocnemius (MG) were assessed via U/S before and after immobilization, with CSA and muscle volume assessed via MRI. RESULTS: With both muscles combined, there were good correlations between each U/S and MRI measure, both before (e.g., CSAMRI vs. MTU/S and CSAU/S: r = 0.88 and 0.94, respectively, both P < 0.0001) and after (e.g., VOLMRI vs. MTU/S and CSAU/S: r = 0.90 and 0.96, respectively, both P < 0.0001) immobilization. The relationship between the methods was notably stronger for MG than TA at each time-point (e.g., CSAMRI vs. MTU/S: MG, r = 0.70, P = 0.0006; TA, r = 0.37, P = 0.10). There was no relationship between the degree of DMA determined by the two methods in either muscle (e.g., TA pre- vs. post-immobilization, VOLMRI: 136 ± 6 vs. 133 ± 5, P = 0.08; CSAU/S: 6.05 ± 0.3 vs. 5.92 ± 0.4, P = 0.70; relationship between methods: r = 0.12, P = 0.75). CONCLUSIONS: Both MTU/S and CSAU/S provide comparable static measures of lower leg muscle size compared with MRI, albeit with weaker agreement in TA compared to MG. Although both MTU/S and CSAU/S can discern differences in DMA susceptibility between muscles, neither can reliably assess degree of DMA. Based on the growing recognition of heterogeneous atrophy profiles between muscles, and the topical importance of less commonly studied muscles (i.e., TA for falls prevention in older adults), future research should aim to optimize accessible methods to determine muscle losses across the body.

Structured training pathway for robotic colorectal surgery: Short-term outcomes from five UK centresAIM: The aim of this study was to assess the short-term outcomes of robotic colorectal surgery implemented through a structured, standardized training pathway in five colorectal centres in the United Kingdom. METHOD: A multicentre retrospective observational study was conducted, involving 523 consecutive patients who underwent robotic colorectal resection between 2015 and 2019. All participating centres followed the European Academy of Robotic Colorectal Surgery training pathway. Patient data, including demographics, operative details, postoperative outcomes and pathology results, were collected and analysed. RESULTS: The study included 447 rectal resections and 76 colonic operations. The median age of the patients was 64.7 years, with the majority of patients (70%) being men. The mean body mass index was 27.4 kg/m2, and 89.7% of the patients underwent surgery for malignancy. The overall conversion rate to open surgery was 4.2%. The median length of stay was 6 days and there was no 30-day mortality. The readmission and reoperation rates were 8.8% and 7.3%, respectively. The anastomotic leak rate was 4.1% for rectal resections and 3.9% for colonic resections. Pathological examination showed a positive circumferential resection margin rate of 2.6%. CONCLUSION: Through the implementation of a structured, standardized training pathway, the participating colorectal centres in the UK achieved safe and effective robotic colorectal surgery pathways with favourable short-term oncological and clinical outcomes. Further studies examining long-term and functional outcomes are needed to assess the broader impact of robotic surgery in colorectal procedures.

Ambulatory management of acute uncomplicated diverticulitis (AmbUDiv study): a multicentre, propensity score matching study.INTRODUCTION: Recent studies have suggested that ambulatory management is feasible for acute uncomplicated diverticulitis (AUD); however, there is still no consensus regarding the most appropriate management settings. This study presents a multi-centre experience of managing patients presenting with AUD, specifically focusing on clinical outcomes and comparing ambulatory treatment with in-patient management. METHODS: A retrospective multi-centre study was conducted across four hospitals in the UK and included all adult patients with computed tomography (CT) confirmed (Hinchey grade 1a) acute diverticulitis over a 12-month period (January - December 2022). Patient medical records were followed up for 1-year post-index episode, and outcomes were compared between those treated through the ambulatory pathway versus inpatient treatment using 1:1 propensity score matching (PSM). All statistical analysis was performed using the R Foundation for Statistical Computing, version 4.4. RESULTS: A total of 348 patients with Hinchey 1a acute diverticulitis were included (260 in-patients; 88 ambulatory pathway), of which nearly a third (31.3%) had a recurrent disease. Inpatient management was dominant (74.7%), with a median of 3 days of hospital stay. PSM resulted in 172 patients equally divided between the two care settings. Ambulatory management was associated with a lower readmission rate (P = 0.02 before PSM, P = 0.08 after PSM), comparable surgical (P = 0.57 before PSM, 0% in both groups after PSM) and radiological interventions (P = 0.99 before and after PSM) within one year. In both matched and non-matched groups, a strong association between readmissions and inpatient management was noted in univariate analysis (P = 0.03 before PSM, P = 0.04 after PSM) and multivariate analysis (P = 0.02 before PSM, P = 0.03 after PSM). CONCLUSION: Our study supports the safety and efficacy of managing patients with AUD through a well-designed ambulatory care pathway. In particular, hospital re-admission rates are lower and other outcomes are non-inferior to in-patient treatment. This has implications for substantial cost-savings and better utilisation of limited healthcare resources.

Predictors of appendicectomy one year after antibiotic treatment for acute appendicitis: Insights from a prospective, multicentre, observational study.BACKGROUND: Surgeons are sometimes reluctant to manage uncomplicated appendicitis non-operatively. Reasons cited include the risk of recurrent appendicitis and the risk of missed appendiceal malignancy. The aim of this study was to address these uncertainties and determine the long-term efficacy of antibiotic versus operative management of appendicitis. METHOD: One-year follow-up of patients enrolled in the multicentre, COVID:HAREM cohort study during March-June 2020 was performed. Initial operative or non-operative management was determined on a case-by-case basis by the responsible surgeon. Outcomes were appendicectomy rate at 1-year, histology of removed appendix and predictors of unsuccessful antibiotic treatment. RESULTS: A total of 625 patients who had non-operative management were included. Emergency appendicectomy had been performed by 1-year in 24% (149/625), with a median time to appendicectomy of 12 days [IQR 1-77] from presentation. Thirty-one patients had elective appendicectomy. Normal histology was reported in 6% of emergency procedures and 58% of elective ones. There were 7 malignancies and 3 neuroendocrine tumors identified at histology. All patients with malignant histology had ≥1 risk factors for malignancy at initial presentation. Faecolithiasis (hazard ratios (HR) 2.3, 95% confidence intervals (CI) 1.51-3.49) and a high Adult Appendicitis Score (AAS >16; HR 2.44, 95% CI 1.52-3.92) were independent risk factors for unsuccessful non-operative management. CONCLUSION: At 1 year, 71% of patients managed non-operatively did not undergo an appendicectomy. Recurrence of appendicitis was associated with faecolithiasis and a high AAS. Patients at higher risk for appendiceal malignancy should have targeted follow-up. These factors should be considered when counseling patients on non-operative management.

The swallowing and speech after transoral robotic surgery—does the site impact the outcome?Transoral robotic surgery (TORS) has been introduced to head and neck surgery as a minimally invasive techqniques to improve the functional outcomes of patients. Compare the functional outcome for swallowing and speech in each site of TORS within the head and neck. Retrospective cohort study for patients who underwent TORS within the head and neck unit. Patients were assessed at four different time points (one day, one month, six months and twelve months, respectively) with bedside/office testing. Methods of testing for swallowing assessment were by the International Dysphagia Diet Standardization Initiative (IDDSI), and speech assessments were carried out using the Understandability of Speech score (USS). Outcomes were compared to patient-specific pre-treatment baseline levels. 68 patients were included. 75% and 40% of the patients resumed normal fluid intake and normal diet immediately after surgery. 8.8% required a temporary feeding tube, with 1% required gastrostomy. There was a steep improvement in diet between 3 and 6 months. Fluid and diet consistency dropped significantly following the majority of transoral robotic surgery with more noticeable diet changes. Early deterioration in diet is temporary and manageable with a modified diet. Rapid recovery of swallowing is achieved before the first year. There is no long-term effect on speech.

Recurrent left main stem stenosis in a young female with Behçet's aortitis: a case reportBACKGROUND: Behçet's disease (BD) is a rare and complex vasculitis disorder renowned for its diverse clinical presentations. Cardiovascular involvement is reported to be present in 7-46% of the patients, with coronary arteries being involved in only 0.5%. The management of cardiovascular complications can be challenging due to the rarity of such cases and the absence of standardized guidelines regarding diagnosis and treatment. CASE SUMMARY: We report the case of a 27-year-old patient with BD with known aortitis and pulmonary arteritis, who presented with recurrent acute coronary syndromes related to critical left main coronary artery stenosis. She was initially managed with percutaneous coronary interventions twice. Following recurrent stent failure, she eventually underwent urgent coronary artery bypass surgery, together with aortic valve replacement and aortic root repair. She made an uneventful recovery and remains well 6 months following her operation. DISCUSSION: This case illustrates the significant challenges that can be encountered when managing coronary complications in patients with BD. Both percutaneous and surgical options have been reported in the literature with variable outcomes. Multi-disciplinary team involvement is of utmost importance in order to offer a balanced therapeutic strategy to these patients. Further research is required to shed light to the unknowns surrounding this rare cohort.

Urgency adjusted outcomes of emergency abdominal surgery for inflammatory bowel diseaseINTRODUCTION: Patients undergoing emergency abdominal surgery for inflammatory bowel disease (IBD) are a complex cohort who are relatively poorly represented in published literature. This is partly due to the lack of consensus of the definition of the term emergency in IBD surgery. There is ongoing and recent work defining clinical urgency for unplanned surgical procedures and categorizing the high-risk surgical patient. This paper aims to report the difference in patient metrics and risks as recorded by the National Emergency Laparotomy Audit (NELA). METHODS: Complete patient data, including histology, were available in the NELA database between 2013 and 2016. Urgency categories recorded by NELA are <2 h, 2-6 h, 6-18 h, and >18 h. Patient characteristics, physiology, biochemistry, and outcomes are reported according to these urgency categories with regression analysis used to compare differences between them. RESULTS: Mortality in Crohn's disease (CD) ranged from 1.4% in the >18 h urgency to 14.6% in the most urgent. In ulcerative colitis (UC), this range was from 3.1% to 14.8%. In both CD and UC, there were significant trends in hemodynamic instability, serum white cell count, serum electrolytes and creatinine, and outcome measures length of stay and unplanned return to theater. CONCLUSIONS: Patients having emergency surgery for IBD are not a single cohort when considering physiology, blood biochemistry, or most importantly, outcomes. Risk counseling and management should reflect this. Hemodynamic changes are subtle and may be missed in this cohort.

The Effect of Tranexamic Acid on Neurosurgical Intervention in Spontaneous Intracerebral Hematoma: Data From 121 Surgically Treated Participants From the Tranexamic Acid in IntraCerebral Hemorrhage-2 Randomized Controlled TrialBACKGROUND AND OBJECTIVES: An important proportion of patients with spontaneous intracerebral hemorrhage (ICH) undergo neurosurgical intervention to reduce mass effect from large hematomas and control the complications of bleeding, including hematoma expansion and hydrocephalus. The Tranexamic acid (TXA) for hyperacute primary IntraCerebral Hemorrhage (TICH-2) trial demonstrated that tranexamic acid (TXA) reduces the risk of hematoma expansion. We hypothesized that TXA would reduce the frequency of surgery (primary outcome) and improve functional outcome at 90 days in surgically treated patients in the TICH-2 data set. METHODS: Participants enrolled in TICH-2 were randomized to placebo or TXA. Participants randomized to either TXA or placebo were analyzed for whether they received neurosurgery within 7 days and their characteristics, outcomes, hematoma volumes (HVs) were compared. Characteristics and outcomes of participants who received surgery were also compared with those who did not. RESULTS: Neurosurgery was performed in 5.2% of participants (121/2325), including craniotomy (57%), hematoma drainage (33%), and external ventricular drainage (21%). The number of patients receiving surgery who received TXA vs placebo were similar at 4.9% (57/1153) and 5.5% (64/1163), respectively (odds ratio [OR] 0.893; 95% CI 0.619-1.289; P-value = .545). TXA did not improve outcome compared with placebo in either surgically treated participants (OR 0.79; 95% CI 0.30-2.09; P = .64) or those undergoing hematoma evacuation by drainage or craniotomy (OR 1.19 95% 0.51-2.78; P-value = .69). Postoperative HV was not reduced by TXA (mean difference -8.97 95% CI -23.77, 5.82; P-value = .45). CONCLUSION: TXA was not associated with less neurosurgical intervention, reduced HV, or improved outcomes after surgery.

Optimal surgical approach for mid-transverse colon cancer: a systematic review and meta-analysis.BACKGROUND AND AIM: The incidence of cancer colon has increased dramatically. In addition, the database lacks a review to analyze the outcomes of surgeries for mid-transverse colon cancer with several recent controversial studies. We aimed to compare the outcomes of extended hemicolectomy versus transverse colectomy for mid-transverse colon cancer. METHOD: PubMed, Scopes, Web of Science and Cochrane Library were searched for eligible studies from inception to 1 December 2022 and a systematic review and meta-analysis were done to detect. RESULTS: According to eligibility criteria, 8 studies (2237 patients) were included in our study. The pooled results of the included studies showed no difference in the 5-year OS, 3-year DFS and 5-year DFS between the two types of surgery (5-year OS, RR = 1.15, 95% CI 0.94-1.39, P = 0.17), (3-year OS, RR = 0.96, 95% CI 0.88-1.06, P = 0.42) and (5-year DFS, RR = 1.21, 95% CI 0.91-1.62, P = 0.20). In addition to that, the recurrence rate and the incidence of complications were similar in the two groups (Recurrence rate, RR = 1.08, 95% CI 0.62-1.89, P = 0.79) and (Complications, RR = 1.07, 95% CI 0.74-1.54, P = 0.72). However, the number of LN harvest and the time of the operation were more in case of extended hemicolectomy. CONCLUSION: Despite harvesting less LN, transverse colectomy has similar oncological outcomes to extended hemicolectomy for mid-transverse colon cancer. In addition to that, there was no significant difference in the incidence of complications between the two surgeries.

Appendectomy versus antibiotic treatment for acute appendicitis.BACKGROUND: Acute appendicitis is one of the most common emergency general surgical conditions worldwide. Uncomplicated/simple appendicitis can be treated with appendectomy or antibiotics. Some studies have suggested possible benefits with antibiotics with reduced complications, length of hospital stay, and the number of days off work. However, surgery may improve success of treatment as antibiotic treatment is associated with recurrence and future need for surgery. OBJECTIVES: To assess the effects of antibiotic treatment for uncomplicated/simple acute appendicitis compared with appendectomy for resolution of symptoms and complications. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, and two trial registers (World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov) on 19 July 2022. We also searched for unpublished studies in conference proceedings together with reference checking and citation search. There were no restrictions on date, publication status, or language of publication. SELECTION CRITERIA: We included parallel-group randomised controlled trials (RCTs) only. We included studies where most participants were adults with uncomplicated/simple appendicitis. Interventions included antibiotics (by any route) compared with appendectomy (open or laparoscopic). DATA COLLECTION AND ANALYSIS: We used standard methodology expected by Cochrane. We used GRADE to assess the certainty of evidence for each outcome. Primary outcomes included mortality and success of treatment, and secondary outcomes included number of participants requiring appendectomy in the antibiotic group, complications, pain, length of hospital stay, sick leave, malignancy in the antibiotic group, negative appendectomy rate, and quality of life. Success of treatment definitions were heterogeneous although mainly based on resolution of symptoms rather than incorporation of long-term recurrence or need for surgery in the antibiotic group. MAIN RESULTS: We included 13 studies in the review covering 1675 participants randomised to antibiotics and 1683 participants randomised to appendectomy. One study was unpublished. All were conducted in secondary care and two studies received pharmaceutical funding. All studies used broad-spectrum antibiotic regimens expected to cover gastrointestinal bacteria. Most studies used predominantly laparoscopic surgery, but some included mainly open procedures. Six studies included adults and children. Almost all studies aimed to exclude participants with complicated appendicitis prior to randomisation, although one study included 12% with perforation. The diagnostic technique was clinical assessment and imaging in most studies. Only one study limited inclusion by sex (male only). Follow-up ranged from hospital admission only to seven years. Certainty of evidence was mainly affected by risk of bias (due to lack of blinding and loss to follow-up) and imprecision. Primary outcomes It is uncertain whether there was any difference in mortality due to the very low-certainty evidence (Peto odds ratio (OR) 0.51, 95% confidence interval (CI) 0.05 to 4.95; 1 study, 492 participants). There may be 76 more people per 1000 having unsuccessful treatment in the antibiotic group compared with surgery, which did not reach our predefined level for clinical significance (risk ratio (RR) 0.91, 95% CI 0.87 to 0.96; I2 = 69%; 7 studies, 2471 participants; low-certainty evidence). Secondary outcomes At one year, 30.7% (95% CI 24.0 to 37.8; I2 = 80%; 9 studies, 1396 participants) of participants in the antibiotic group required appendectomy or, alternatively, more than two-thirds of antibiotic-treated participants avoided surgery in the first year, but the evidence is very uncertain. Regarding complications, it is uncertain whether there is any difference in episodes of Clostridium difficile diarrhoea due to very low-certainty evidence (Peto OR 0.97, 95% CI 0.24 to 3.89; 1 study, 1332 participants). There may be a clinically significant reduction in wound infections with antibiotics (RR 0.25, 95% CI 0.09 to 0.68; I2 = 16%; 9 studies, 2606 participants; low-certainty evidence). It is uncertain whether antibiotics affect the incidence of intra-abdominal abscess or collection (RR 1.58, 95% CI 0.61 to 4.07; I2 = 19%; 6 studies, 1831 participants), or reoperation (Peto OR 0.13, 95% CI 0.01 to 2.16; 1 study, 492 participants) due to very low-certainty evidence, mainly due to rare events causing imprecision and risk of bias. It is uncertain if antibiotics prolonged length of hospital stay by half a day due to the very low-certainty evidence (MD 0.54, 95% CI 0.06 to 1.01; I2 = 97%; 11 studies, 3192 participants). The incidence of malignancy was 0.3% (95% CI 0 to 1.5; 5 studies, 403 participants) in the antibiotic group although follow-up was variable. Antibiotics probably increased the number of negative appendectomies at surgery (RR 3.16, 95% CI 1.54 to 6.49; I2 = 17%; 5 studies, 707 participants; moderate-certainty evidence). AUTHORS' CONCLUSIONS: Antibiotics may be associated with higher rates of unsuccessful treatment for 76 per 1000 people, although differences may not be clinically significant. It is uncertain if antibiotics increase length of hospital stay by half a day. Antibiotics may reduce wound infections. A third of the participants initially treated with antibiotics required subsequent appendectomy or two-thirds avoided surgery within one year, but the evidence is very uncertain. There were too few data from the included studies to comment on major complications.

Post-prostatectomy incontinence: a guideline of guidelines.AIM: To provide a comprehensive review of guidelines from various professional organisations on the work-up and management of post-prostatectomy Incontinence (PPI). MATERIALS AND METHODS: The following guidelines were included in this review: European Association of Urology (EAU 2023), American Urological Association/Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction (AUA/SUFU 2019), International Consultation on Incontinence (ICI, 2018), the Canadian Urological Association (CUA, 2012) and the Urological Society of India (USI, 2018). RESULTS: In general, the guidelines concur regarding the significance of conducting a comprehensive history and physical examination for patients with post-prostatectomy incontinence (PPI). However, there are variations among the guidelines concerning the recommended additional investigations. In cases of troublesome PPI, male slings are typically recommended for mild to moderate urinary incontinence (UI), while artificial urinary sphincters are preferred for moderate to severe UI, although the precise definition of this severity remains unclear. The guidelines provided by AUA/SUFU and the ICI have offered suggestions for managing complications or persistent/recurrent UI post-surgery, though some differences can be observed within these recommendations as well. CONCLUSION: This is a first of its kind review encompassing Guidelines on PPI spanning over a decade. Although guidelines share overarching principles, nuanced variations persist, posing challenges for clinicians. This compilation consolidates and highlights both the similarities and differences among guidelines, providing a comprehensive overview of PPI diagnosis and management for practitioners. It is our expectation that as more evidence emerges in this and other areas of PPI management, the guidelines will converge and address crucial patient-centric aspects.

Classification and stratification in pilonidal sinus disease: findings from the PITSTOP cohortAIM: Research in pilonidal disease faces several challenges, one of which is consistent and useful disease classification. The International Pilonidal Society (IPS) proposed a four-part classification in 2017. The aim of this work was to assess the validity and reliability of this tool using data from the PITSTOP cohort study. METHOD: Face validity was assessed by mapping the items/domains in the IPS tool against tools identified through a systematic review. Key concepts were defined as those appearing in more than two-thirds of published tools. Concurrent and predictive validity were assessed by comparing key patient-reported outcome measures between groups at baseline and at clinic visit. The outcomes of interest were health utility, Cardiff Wound Impact Questionnaire (CWIQ) and pain score between groups. Significance was set at p = 0.05 a priori. Interrater reliability was assessed using images captured during the PITSTOP cohort. Ninety images were assessed by six raters (two experts, two general surgeons and two trainees), and classified into IPS type. Interrater reliability was assessed using the unweighted kappa and unweighted Gwet's AC1 statistics. RESULTS: For face validity items represented in the IPS were common to other classification systems. Concurrent and predictive validity assessment showed differences in health utility and pain between groups at baseline, and for some treatment groups at follow-up. Assessors agreed the same classification in 38% of participants [chance-corrected kappa 0.52 (95% CI 0.42-0.61), Gwet's AC1 0.63 (95% CI 0.56-0.69)]. CONCLUSION: The IPS classification demonstrates key aspects of reliability and validity that would support its implementation.

Exploring the utility of bedside tests for predicting cardiorespiratory fitness in older adults.OBJECTIVES: Cardiorespiratory fitness (CRF) declines with advancing and has also, independent of age, been shown to be predictive of all-cause mortality, morbidity, and poor clinical outcomes. In relation to the older patient, there is a particular wealth of evidence highlighting the relationship between low CRF and poor surgical outcomes. Cardiopulmonary exercise testing (CPET) is accepted as the gold-standard measure of CRF. However, this form of assessment has significant personnel and equipment demands and is not feasible for those with certain age-associated physical limitations, including joint and cardiovascular comorbidities. As such, alternative ways to assess the CRF of older patients are very much needed. METHODS: Sixty-four participants (45% female) with a median age of 74 (65-90) years were recruited to this study via community-based advertisements. All participants completed three tests of physical function: (1) a step-box test; (2) handgrip strength dynamometry; and (3) a CPET on a cycle ergometer; and also had their muscle architecture (vastus lateralis) assessed by B-mode ultrasonography to provide measures of muscle thickness, pennation angle, and fascicle length. Multivariate linear regression was then used to ascertain bedside predictors of CPET parameters from the alternative measures of physical function and demographic (age, gender, body mass index (BMI)) data. RESULTS: There was no significant association between ultrasound-assessed parameters of muscle architecture and measures of CRF. VO2peak was predicted to some extent from fast step time during the step-box test, gender, and BMI, leading to a model that achieved an R 2 of 0.40 (p < 0.001). Further, in aiming to develop a model with minimal assessment demands (i.e., using handgrip dynamometry rather than the step-box test), replacing fast step time with non-dominant HGS led to a model which achieved an R 2 of 0.36 (p < 0.001). Non-dominant handgrip strength combined with the step-box test parameter of fast step time and BMI delivered the most predictive model for VO2peak with an R 2 of 0.45 (p < 0.001). CONCLUSIONS: Our findings show that simple-to-ascertain patient characteristics and bedside assessments of physical function are able to predict CPET-derived CRF. Combined with gender and BMI, both handgrip strength and fast step time during a step-box test were predictive for VO2peak. Future work should apply this model to a clinical population to determine its utility in this setting and to explore if simple bedside tests are predictive of important clinical outcomes in older adults (i.e., post-surgical complications).

Patient-reported outcomes in inguinal hernia surgery-Results from the GENESIS study: A multinational multicenter study.BACKGROUND: Chronic groin pain following inguinal hernia repair can be troublesome. The current literature is limited, especially from Asia and Africa. We aimed to evaluate patient-reported outcomes using the Carolinas Comfort Scale (CCS) following inguinal hernia repair at an international level, especially to include patients from Asia and Africa. METHODS: An international cohort of surgeons was invited to collaborate and collect data of consecutive adult patients who underwent inguinal hernia repair. The data were collected to allow at least 2 years of follow-up. A total score for CCS was calculated and compared for the following groups-patient age <30 years versus (vs.) > 30 years; open versus laparoscopic repair, emergency versus elective surgery, and unilateral versus bilateral hernia repair. The CCS scores between Asia, Africa, and Europe were also compared. RESULTS: The mean total CCS score of patients operated in Asia (n = 891), Europe (n = 853), and Africa (n = 157) were 7.32, 14.6, and 19.79, respectively. The total CCS score was significantly higher following open repair, emergency repair, and unilateral repair, with surgical site infections (SSI) and recurrence. In the subgroup analysis, the patients who underwent elective open repair in Europe had higher CCS scores than those in Asia. CONCLUSION: About 15% of patients had a CCS score of more than 25 after a minimum follow-up of 2 years. The factors that influence CCS scores are indication, approach, complications, and geographic location.

Molecular mechanisms underpinning favourable physiological adaptations to exercise prehabilitation for urological cancer surgeryBACKGROUND: Surgery for urological cancers is associated with high complication rates and survivors commonly experience fatigue, reduced physical ability and quality of life. High-intensity interval training (HIIT) as surgical prehabilitation has been proven effective for improving the cardiorespiratory fitness (CRF) of urological cancer patients, however the mechanistic basis of this favourable adaptation is undefined. Thus, we aimed to assess the mechanisms of physiological responses to HIIT as surgical prehabilitation for urological cancer. METHODS: Nineteen male patients scheduled for major urological surgery were randomised to complete 4-weeks HIIT prehabilitation (71.6 ± 0.75 years, BMI: 27.7 ± 0.9 kg·m2) or a no-intervention control (71.8 ± 1.1 years, BMI: 26.9 ± 1.3 kg·m2). Before and after the intervention period, patients underwent m. vastus lateralis biopsies to quantify the impact of HIIT on mitochondrial oxidative phosphorylation (OXPHOS) capacity, cumulative myofibrillar muscle protein synthesis (MPS) and anabolic, catabolic and insulin-related signalling. RESULTS: OXPHOS capacity increased with HIIT, with increased expression of electron transport chain protein complexes (C)-II (p = 0.010) and III (p = 0.045); and a significant correlation between changes in C-I (r = 0.80, p = 0.003), C-IV (r = 0.75, p = 0.008) and C-V (r = 0.61, p = 0.046) and changes in CRF. Neither MPS (1.81 ± 0.12 to 2.04 ± 0.14%·day-1, p = 0.39) nor anabolic or catabolic proteins were upregulated by HIIT (p > 0.05). There was, however, an increase in phosphorylation of AS160Thr642 (p = 0.046) post-HIIT. CONCLUSIONS: A HIIT surgical prehabilitation regime, which improved the CRF of urological cancer patients, enhanced capacity for skeletal muscle OXPHOS; offering potential mechanistic explanation for this favourable adaptation. HIIT did not stimulate MPS, synonymous with the observed lack of hypertrophy. Larger trials pairing patient-centred and clinical endpoints with mechanistic investigations are required to determine the broader impacts of HIIT prehabilitation in this cohort, and to inform on future optimisation (i.e., to increase muscle mass).

Statistical primer: using prognostic models to predict the future: what cardiothoracic surgery can learn from Strictly Come DancingOBJECTIVES: Prognostic models are widely used across medicine and within cardiothoracic surgery, where predictive tools such as EuroSCORE are commonplace. Such models are a useful component of clinical assessment but may be misapplied. In this article, we demonstrate some of the major issues with risk scores by using the popular BBC television programme Strictly Come Dancing (known as Dancing with the Stars in many other countries) as an example. METHODS: We generated a multivariable prognostic model using data from the then-completed 19 series of Strictly Come Dancing to predict prospectively the results of the 20th series. RESULTS: The initial model based solely on demographic data was limited in its predictive value (0.25, 0.22; R2 and Spearman's rank correlation, respectively) but was substantially improved following the introduction of early judges' scores deemed representative of whether contestants could actually dance (0.40, 0.30). We then utilize our model to discuss the difficulties and pitfalls in using and interpreting prognostic models in cardiothoracic surgery and beyond, particularly where these do not adequately capture potentially important prognostic information. CONCLUSION: Researchers and clinicians alike should use prognostic models cautiously and not extrapolate conclusions from demographic data alone.

Guideline of guidelines: Postprostatectomy incontinenceThe diagnosis of Postprostatectomy Incontinence (PPI) relies heavily on expert opinions. Challenges in assessing and treating PPI arise due to limited robust evidence and the absence of a concise definition, resulting in diverse reported incidence rates. In addition, unclear pathophysiological mechanisms, and lack of consensus on diagnostic work-up and treatment selection contribute to knowledge gaps. We aimed to provide a comprehensive review of guidelines from various professional organisations on the work-up and management of PPI. The following guidelines were included in this review: European Association of Urology (EAU 2023), American Urological Association/Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction (AUA/SUFU 2019), International Consultation on Incontinence (ICI, 2018), the Canadian Urological Association (CUA, 2012) and the Urological Society of India (USI, 2018). In general, the guidelines concur regarding the significance of conducting a comprehensive history and physical examination for patients with post-prostatectomy incontinence (PPI). However, there are variations among the guidelines concerning the recommended additional investigations. In cases of troublesome PPI, male slings are typically recommended for mild to moderate urinary incontinence (UI), while artificial urinary sphincters (AUS) are preferred for moderate to severe UI, although the precise definition of this severity remains unclear. The guidelines provided by AUA/SUFU and the ICI have offered suggestions for managing complications or persistent/recurrent UI post-surgery, though some differences can be observed within these recommendations as well. This is a first of its kind review encompassing Guidelines on PPI spanning over a decade. Although guidelines share overarching principles, nuanced variations persist, posing challenges for clinicians. This compilation consolidates and highlights both the similarities and differences among guidelines, providing a comprehensive overview of PPI diagnosis and management for practitioners. It is our expectation that as more evidence emerges in this and other areas of PPI management, the guidelines will converge and address crucial patient-centric aspects.

Ultrasound-guided percutaneous retrieval of non-radiopaque radial line using a microsnareRadial arterial lines are inserted in critically ill patients admitted to hospital intensive care units for continuous monitoring of their blood pressure. On removal the line can rarely become transected, potentially leading to thrombosis of the radial artery. Retrieval of the broken fragment can be achieved by open surgery, however other retrieval methods using ultrasound-guidance have been performed as they are considered safer and less invasive. We describe our technique of ultrasound-guided percutaneous retrieval of a broken non-radioopaque radial line in one patient, which involved the use of a microsnare. Under local anaesthesia and ultrasound guidance, a 6 Fr 5.5 cm short brite tip sheath was introduced into the radial artery, followed by a microsnare which was used to capture the arterial line, track the line back into the sheath and remove it uneventfully. The use of a microsnare under ultrasound-guidance is only one method to retrieve transected radial lines, with other interventional methods described in the literature. It enables a minimally invasive and safer approach to this potentially critical challenge and can help affected patients avoid open surgery to achieve the same management outcome
