[Colonoscopic perforation: 6 cases in Abidjan, Cote d'Ivoire].

OBJECTIVES

The purpose of this report is to describe diagnostic and therapeutic management of colonoscopic perforation and identify risk factors.

MATERIAL AND

METHODS

The charts of 6 patients who underwent surgery for colonoscopic perforation between January 2003 and December 2008 were reviewed. Study data included patient age, indication for colonoscopy, operative findings, repair technique, and outcome.

RESULTS

All 6 perforations occurred during diagnostic colonoscopy. There were 5 females and 1 male. Endoscopy was performed by an experienced operator in 5 cases and by a training fellow in 1. Preparation of the colon was considered as good in 5 cases. The operator reported procedural problems in only 1 case. Diagnosis of perforation was immediate in 5 cases and delayed for 30 hours in 1. The lesion was located in the sigmoid colon in 5 cases and transverse colon in 1. All patients underwent laparotomy. The repair technique consisted of simple closure in 2 cases, closure with colostomy in one, and bowel resection with anastomosis (n=2). Two deaths occurred intraoperatively in I case and postoperatively in 1. The patient who died intraoperatively had not yet undergone repair when death occurred. In both patients who died, laparotomy was performed late in the presence of co-morbidity.

CONCLUSION

Colonic perforation is a rare but severe iatrogenic complication following colonoscopic examination. Early recognition and treatment are essential to optimize outcome. Prevention depends on training to obtain skillful advancement technique.
