Endoscopic Biliary Stent: Experience in 57 Patients with Various Biliary Problems at Songklanagarind Hospital
Abstract
We report our experience in management and follow-up of 57 patients with biliary obstruction treated by endoscopic stent insertion or combined percutaneous and endoscopic technique between 1990 and 1995. There were 40 patients with malignant diseases and 17 patients with benign diseases. The stent was successfully inserted in 28 cases (70%) of malignant obstruction and in 17 cases (100%) of benign obstruction. Jaundice was improved in 88.9% in malignant group. Clinical improvement was achieved in 82% in benign group. Early complications occurred in 13 cases (benign = 4, malignant = 9). The mortality rate was 5.26 per cent with procedure-related mortality of 1.75 per cent. Median survival available in 23 patients with malignant obstruction was 11 weeks and 25 per cent survived more than 6 months. Endoscopic stent insertion is an alternative in the therapeutic options available. The procedure is a useful and safe method in the treatment of malignant and benign biliary obstruction but its role as compared with surgery in terms of efficacy, cost and quality of life in our setting remains to be evaluated in controlled study.
