Should endoscopic stenting be the initial treatment of malignant biliary obstruction?

Abstract

Forty-two patients with biliary obstruction caused by a stricture had a diagnostic ERCP with subsequent insertion of a straight 10G endoprosthesis. These patients represented 70% of a cohort in which stent insertion had been attempted. The majority (63%) had pancreatic carcinoma, but 22% had malignant hilar obstruction. Five patients (12%) died within a few days of stent insertion; ERCP may have contributed to two deaths. Jaundice was relieved in all survivors. Median hospital stay was 6 days (range 2-32 days). After further investigation, nine patients were thought to be potentially curable and underwent laparotomy. Late complications after stent insertion alone included cholangitis (26%) and recurrent jaundice (28%). Only one patient developed gastric outlet obstruction and needed a gastroenterostomy. Median survival in the endoprosthesis group was 11 weeks (range 2-84 weeks). Survival was longer for patients with bile duct (14 weeks) rather than hilar strictures (6 weeks). Median survival after subsequent surgery was 40 weeks (range 4-80 weeks) with two long-term survivors. This study confirms that ERCP and stent insertion is a useful initial treatment for obstructive jaundice due to a biliary stricture, being both diagnostic and therapeutic. Subsequent evaluation for curative surgery is not precluded and in the majority of cases worthwhile palliation may be achieved by stenting alone.
