Objectives:
Our study was undertaken to better assess the circumstances of perforation during colonoscopy.
Methods:
All cases observed in our department between 1978 and 1994 were computer recorded. During this period, 5,822 colonoscopies were performed, including 872 with at least one polypectomy.
Results:
All perforations occurred during colonoscopies performed under anaesthesia (n = 3,373 vs 2,449 without anaesthesia). There were a total of 15 observations of colonic perforations, 1 perforation in 388 colonoscopies. Ten perforations occurred during diagnostic colonoscopies (0.20%), 5 after polypectomy (0.57%). Eight of 10 perforations complicating diagnostic colonoscopies occurred below an impassable stricture. Two patients died from this complication (0.03% of all colonoscopies).
Conclusions:
Our study suggests that endoscopic exploration of colonic stricture, in addition to anaesthesia, increases the risk of colonic perforation.
