Large iatrogenic colonic perforation treated by endoscopic suturing [Large perforation colique au cours d'une coloscopie traitée par fermeture endoscopique : rapport de deux observations]

摘要

Perforation of the colon during colonoscopy is still one of the most severe complications of this technique and occurs with a frequency of between 0.12 % and 0.2 % of cases after diagnostic colonoscopy and in up to 3 % of patients after therapeutic colonoscopy. The site of perforation is usually the sigmoid colon. The gold standard for treatment of this complication is surgery to be performed as rapidly as possible: a simple suture and peritoneal cleaning, with limited resection and anastomosis or colostomy only in case of confirmed fecal peritonitis. However, interventional endoscopy has made progress, in particular endoscopic suturing and Natural Orifice Transluminal Endocopic Surgery (NOTES) has been developed. There are several reports of endoscopically sutured perforated colons, most less than 10 mm. We report our experience of two colonic perforations which were at least 10 mm treated by endoscopic suturing with hemoclips: a perforated sigmoid diverticulum during simple colonoscopy in the first case and a large polypectomy by endoscopic mucosal resection of the ascending colon in the second.
