Background: Various strategies were proposed to reduce postoperative ileus after colorectal surgery. This umbrella review aimed to provide a comprehensive overview of current evidence on measures to reduce the incidence and severity of postoperative ileus after colorectal surgery.

Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant systematic search was conducted in PubMed and Scopus to identify systematic reviews that assessed the efficacy of interventions used to prevent postoperative ileus after colorectal surgery.

Outcomes of Early Versus Standard Closure of Diverting Ileostomy After Proctectomy: Meta-analysis and Meta-regression Analysis of Randomized Controlled Trials.

Objective: We aimed to compare outcomes of early and standard closure of diverting loop ileostomy (DLI) after proctectomy and determine risk factors for anastomotic leak (AL) and complications.

Background: Formation of DLI has been a routine practice after proctectomy to decrease the incidence and potential adverse sequela of AL.

Methods: PubMed, Scopus, and Web of Science were searched for randomized controlled trials (RCTs) that compared outcomes of early versus standard closure of DLI after proctectomy.

Background: Endoscopic management of colorectal polyps includes detection, characterization, and therapeutic strategies. Pit pattern analysis is a useful tool when differentiating neoplastic and non-neoplastic colorectal polyps.

Aim: To correlate pit pattern characterization of colorectal polyps using SPIES endoscopy and the histopathology.

Sodium picosulfate/magnesium citrate versus 4L split-dose polyethylene glycol for bowel cleansing prior to colonoscopy in high fibre diet African patients.

Introduction: an adequate bowel preparation is essential for good mucosal inspection during colonoscopy. This study aims to compare the efficacy of two validated oral lavage solutions for colonoscopy preparation in African patients.
