The Clinical Course of ERCP-related Bowel Perforation / 대한소화기내시경학회지

ABSTRACT

BACKGROUND/AIMS: The management of small-bowel perforations associated with endoscopic retrograde cholangiopancreatography (ERCP) or endoscopic sphincterotomy (EST) is still controversial. The purpose of this study was to analyze the treatment and outcome of patients with ERCP-related perforations in a single tertiary medical center. METHODS: Of 18,379 cases of ERCPs performed between January 1990 and December 2003, twenty-six patients (0.14%) with perforation were identified and medical chart were reviewed retrospectively. RESULT: EST were performed in 10,231 patients and perforation occurred in 18 patients. Four out of 18 patients with small-bowel perforation related to EST underwent surgical operation and the rest 14 patients recovered with conservative treatment alone. Of the rest 8 perforation patients unrelated to EST, perforation occurred during the insertion of endoscope in 7 patients and catheter manipulation in 1 patient. All but one perforations associated with mechanical injury by endoscope itself were managed with an emergent laparotomy, and the one patient with perforation related to catheter manipulation recovered with conservative treatment. CONCLUSIONS: A small-bowel perforation related to endoscope per se usually required a surgery, but sphincterotomy related perforations rarely did so. The prevalence and mortality rate of small-bowel perforations associated with ERCP and/or EST were 0.14% and 0%, respectively, in a single tertiary medical center.
