[Double review of the right colon vs single review during colonoscopy for the detection of colon polyps and adenomas: systematic review of the literature].

Unlabelled: Colonoscopy screening is an effective method to prevent colon cancer through the detection of polyps on which colon cancer develops in a higher percentage; however, the detection of these lesions varies in the different segments of the colon and the detection rate of them in the right colon is usually lower.

Objective: The objective of this study is to evaluate whether double endoscopic revision of the right colon during colonoscopy is a mechanism to improve its performance in terms of polyp detection rate (TDP) and adenoma detection rate (ADR).

Materials And Methods: Systematic review and meta-analysis of the literature including randomized clinical trials that evaluated repeat right-sight examination by colonoscopy compared to standard view to improve detection of polyps and adenomas.

[E-VAC therapy as treatment of complications in gastrointestinal surgery in a gastroenterology reference center in Colombia: Case series].

Gastrointestinal postoperative anastomotic leaks and fistulas occur frequently and many are managed surgically; however, endoscopic interventions have shown to improve healing outcomes and length of hospital stay. The experience of vacuum-assisted closure therapy (E-VAC) is described, in complications such as fistulas and postoperative anastomotic leaks, in a gastrointestinal reference center in Colombia. A case series study was carried out in patients with anastomotic leaks and fistulas at different levels of the digestive tract, treated by E-VAC, by the Gastroenterology Service in Colombia, during a period from February 2019 to November 2021.

Multimodal Endoscopic Management of Esophageal Perforations as a Complication of Peroral Endoscopic Myotomy for a Zenker's Diverticulum.

Zenker's diverticulum develops because of a weakness in Killian's triangle, leading to a mucosal and submucosal herniation. Its treatment has evolved from morbid surgical interventions to safer endoscopic techniques such as peroral endoscopic myotomy (Z-POEM). Despite being a safe technique, Z-POEM is not free of complications such as perforations, bleeding, pneumoperitoneum, and pneumothorax, for which new endoscopic techniques have been developed.
