Summary of the current guidelines for managing iatrogenic colorectal perforations and the evolving role of endoluminal vacuum therapy

Abstract

Colonoscopy represents a safe procedure that is widely used in medical practice either to diagnose or treat various gastrointestinal diseases. During the last few years, the incidence rate of perforations in colonoscopic procedures has increased, especially in therapeutic colonoscopies. The recent advancements in endoscopic techniques and gastrointestinal tumoral resection procedures such as endoscopic mucosal resection, endoscopic full-thickness resection, and endoscopic submucosal dissection (ESD) could be a risk factor for this increased risk. The incidence rate of mortality of serious colonoscopic perforations is 7.1%. The management plan for these perforations starts with conservative treatment in mild cases, endoscopic closure, and surgical management in severe cases. Recently, endoluminal vacuum therapy was found to be effective in the management of colorectal perforations and this has been reported in multiple case reports. This editorial provides an overview of the current guidelines for the management of iatrogenic colorectal perforations. These insights are from the perspectives of endoscopists and gastroenterologists. We also present a management algorithm based on the guidelines of the European Society of Gastrointestinal Endoscopy, the American Gastroenterological Association, and the World Society of Emergency Surgery. We also discussed in brief the use of endoluminal vacuum therapy in colorectal perforations.
