Importance Postoperative urinary retention (POUR) is a well-recognized complication of inguinal hernia repair (IHR). A variable incidence POUR has previously been reported in this context, and contradictory evidence surrounds potential risk factors. Objective To ascertain the of, explore factors for, determine health service outcomes following elective IHR. Design, Setting, Participants The Retention Urine After Inguinal Hernia Elective Repair (RETAINER I) study, an international,...
Studies regarding the epidemiology of systemic lupus erythematosus (SLE) are lacking in Argentina. Our purpose was to estimate incidence and prevalence SLE a university hospital-based health management organisation Buenos Aires (HIMCP).For calculation, population at risk included all adult members HIMCP, with continuous affiliation for least 1 year from January 1998 2009. Each person followed until he/she voluntarily left death or finalisation study. Multiple methods case finding were used...
An estimated 2.5-3 million individuals (0.4%) in Europe are affected by inflammatory bowel disease (IBD). Whilst incidence rates for IBD stabilising across Europe, the prevalence is rising and subsequently resulting a significant cost to healthcare system of an 4.6-5.6 billion euros per year. Hospitalisation surgical resection generally on downward trend, which contrary novel medication. This signifies large part burden. Despite publicly funded systems most European countries, there still...
The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad other responsibilities. From April to May 2023, we conducted CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, logistic regression (SPSS
Abstract Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods internationally intended protocol, iteratively co-developed by multistage Delphi process, comprised online educational module introducing stratification, intraoperative checklist, harmonized surgical...
Abstract Background Recent evidence challenges the current standard of offering surgery to patients with ileocecal Crohn’s disease only when they present complications disease. Methods A retrospective, multicenter comparative analysis was performed including operated for primary CD at 12 referral centers. Patients were divided in 2 groups, according indication inflammatory (ICD) or complicated (CCD) phenotype. Short-term results compared. on isolated ileocaecal (last 50 cm terminal ileum and...
Abstract Aim Recent evidence challenges the current standard of offering surgery to patients with ileocaecal Crohn's disease (CD) only when they present complications disease. The aim this study was compare short‐term results who underwent primary resection for either inflammatory (luminal disease, earlier in course) or complicated phenotypes, hypothesizing that latter would be associated worse postoperative outcomes. Method A retrospective, multicentre comparative analysis performed...
Early surgical treatment for patients with ileocecal Crohn's disease (CD) could be an alternative to biological therapy. The aim of this study is compare operative outcomes following resection luminal and complicated CD. Patients operated primary CD during 8 years in one tertiary-referral hospital were allocated into 2 groups: those early (luminal) (ECD), complications (CCD). A retrospective comparative analysis was performed. total 273 included the analysis, 85 (31%) which ECD group. No...

Social Media Working Group interviewed experts who have made significant contributions DEI colorectal surgery were acknowledged opinion field. interviews focused their...
The aim of this work was to compare lymph node (LN) yield in patients operated on for right colon cancer (RCC) using a laparoscopic approach between those receiving an intracorporeal (ICA) or extracorporeal anastomosis (ECA).
Abstract Introduction Rectal cancer is a prevalent disease that requires multidisciplinary management. Results of treatment patients suffering from this malignancy in Latin America have been scarcely reported before. Methods A retrospective, multicenter study was conducted to report preoperative and operative characteristics intervened for rectal centers during 2015–2022, the short-term results were analyzed. The open any center receiving patients, irrespective volume. main outcome 30-day...
The optimal treatment of anastomotic leak after rectal cancer resection is unclear. This worldwide cohort study aimed to provide an overview four strategies applied.Patients from 216 centres and 45 countries with between 2014 2018 were included. Treatment was categorized as salvage surgery, faecal diversion passive or active (vacuum) drainage, no primary/secondary diversion. primary outcome 1-year stoma-free survival. In addition, drainage compared using propensity score matching (2 : 1).Of...
Abstract Background Surgical management for patients with inflammatory ileocecal Crohn’s disease (CD) could be a reasonable alternative to second-line medical treatment. Methods A retrospective analysis of intervened primary CD uncomplicated (inflammatory) phenotype at four referral hospitals during 2012-2021 was performed. The objective assess short and long-term outcomes operated on inflammatory, CD. Patients due (last 50 cm the terminal ileum cecum), were considered eligible participate...
The LATAM-URG study was initiated to address a critical gap in the understanding of incidence, management, and outcomes urgent abdominal procedures Latin America. primary purpose this is gather comprehensive data that will inform clinical practice, improve patient outcomes, contribute global body knowledge on emergency surgical care. Specifically, aims quantify burden these procedures, assess variations identify factors high mortality associated with laparotomy region.
Complications after ileocecal resection for Crohn's disease (CD) are frequent. The aim of this study was to analyze risk factors postoperative complications these procedures.We conducted a retrospective analysis patients treated surgically limited the region during an 8-year period at 10 medical centers specialized in inflammatory bowel (IBD) Latin America. Patients were allocated into 2 groups: those who presented major (Clavien-Dindo > II), "postoperative complication" (POC) group; and did...
