Impact of hospital volume on failure to rescue for complications requiring reoperation after elective colorectal surgery: multicentre propensity score-matched cohort study.

Background: It has previously been reported that there are similar reoperation rates after elective colorectal surgery but higher failure-to-rescue (FTR) rates in low-volume hospitals (LVHs) versus high-volume hospitals (HVHs). This study assessed the effect of hospital volume on reoperation rate and FTR after reoperation following elective colorectal surgery in a matched cohort.

Methods: Population-based retrospective multicentre cohort study of adult patients undergoing reoperation for a complication after an elective, non-centralized colorectal operation between 2006 and 2017 in 11 hospitals.

Systematic Reviews and Meta-analyses of the Procedure-specific Risks of Thrombosis and Bleeding in General Abdominal, Colorectal, Upper Gastrointestinal, and Hepatopancreatobiliary Surgery.

Objective: To provide procedure-specific estimates of symptomatic venous thromboembolism (VTE) and major bleeding after abdominal surgery.

Background: The use of pharmacological thromboprophylaxis represents a trade-off that depends on VTE and bleeding risks that vary between procedures; their magnitude remains uncertain.

Methods: We identified observational studies reporting procedure-specific risks of symptomatic VTE or major bleeding after abdominal surgery, adjusted the reported estimates for thromboprophylaxis and length of follow-up, and estimated cumulative incidence at 4 weeks postsurgery, stratified by VTE risk groups, and rated evidence certainty.

Stoma reversal after Hartmann's procedure for acute diverticulitis.

Background: Hartmann's procedure is a treatment option for perforated acute diverticulitis, especially when organ dysfunction(s) are present. Its use has been criticized mostly out of fear of high permanent stoma rate. The aim of this study was to investigate the rate of stoma reversal, reasons behind nonreversal, and safety of reversal surgery.

Systematic reviews of observational studies of Risk of Thrombosis and Bleeding in General and Gynecologic Surgery (ROTBIGGS): introduction and methodology.

Background: Venous thromboembolism (VTE) and bleeding are serious and potentially fatal complications of surgical procedures. Pharmacological thromboprophylaxis decreases the risk of VTE but increases the risk of major post-operative bleeding. The decision to use pharmacologic prophylaxis therefore represents a trade-off that critically depends on the incidence of VTE and bleeding in the absence of prophylaxis.

Three-dimensional versus two-dimensional high-definition laparoscopy in transabdominal preperitoneal inguinal hernia repair: a prospective randomized controlled study.

Background: Three-dimensional (3D) laparoscopy improves technical efficacy in laboratory environment, but evidence for clinical benefit is lacking. The aim of this study was to determine whether the 3D laparoscopy is beneficial in transabdominal preperitoneal laparoscopic inguinal hernia repair (TAPP).

Method: In this prospective, single-blinded, single-center, superior randomized trial, patients scheduled for TAPP were randomly allocated to either 3D or two-dimensional (2D) TAPP laparoscopic approaches.

Prognosis of sporadic resected small (≤2 cm) nonfunctional pancreatic neuroendocrine tumors - a multi-institutional study.

Background: Malignant potential of small (≤20 mm) nonfunctional pancreatic neuroendocrine tumors (sNF-PNET) is difficult to predict and management remain controversial. The aim of this study was to assess the prognosis of sporadic nonmetastatic sNF-PNETs.

Methods: Patients were identified from databases of 16 centers.

Symptomatic Treatment for Uncomplicated Acute Diverticulitis: A Prospective Cohort Study.

Background: Even though evidence for nonantibiotic treatment of uncomplicated diverticulitis exists, it has not gained widespread adoption.

Objective: The aim of this prospective single-arm study was to analyze the safety and efficacy of symptomatic (nonantibiotic) treatment for uncomplicated diverticulitis during a 30-day follow-up period.

Design: This study is a single-arm prospective trial (ClinicalTrials.

Staging of acute diverticulitis based on clinical, radiologic, and physiologic parameters.

Background: Acute diverticulitis is a broad spectrum of diseases with highly varying mortality and need for surgery. The aim of this study was to create an accurate staging of diverticulitis, which could be used both preoperatively and intraoperatively to predict outcome and guide treatment.

Methods: This was a retrospective study of patients treated for diverticulitis in a secondary and tertiary referral center.

Nonoperative management of perforated diverticulitis with extraluminal air is safe and effective in selected patients.

Background: The optimal treatment for diverticulitis with extraluminal air is controversial.

Objective: The purpose of this research was to evaluate the safety and effectiveness of nonoperative treatment of acute diverticulitis with extraluminal air.

Design: This was a retrospective cohort.
