Effectiveness of combined biliary and duodenal stenting in patients with malignant biliary and duodenal obstruction

Abstract

Introduction. Concomitant biliary and duodenal obstructions are not uncommon complications in patients with gastroduodenal or pancreatobiliary malignancies. Alleviation of obstruction is very important for the palliation of inoperable patients. We studied the clinical outcomes of combined biliary and duodenal stenting. Methods. Between January 2003 and January 2010, the records of 24 patients who underwent biliary and duodenal stent placement due to inoperable malignant biliary and duodenal obstruction were reviewed retrospectively. Results. Of the 24 patients, a duodenal stent was placed after biliary stenting in 23 patients and a biliary stent was placed after duodenal stenting in one patient. Biliary stents were placed endoscopically (33 cases) or percutaneously (14 cases). Duodenal stents were placed endoscopically by fluoroscopic guidance in all patients. Oral feeding was possible at a mean of 2.7 ± 1.2 days (range, 1–6 days) after duodenal stenting. Acute pancreatitis and acute cholangitis developed in three patients and one patient, respectively, as early complications after biliary stenting. Biliary stent occlusion was developed in 12 patients and was treated successfully by stent reinsertion. As complications of duodenal stent, one case of stent migration and five cases of stent occlusion developed. Median survival after initial bilioduodenal stenting was 195.5 days (range, 21–725 days). Stent patency was well maintained in 83.3% of patients after combined stent placements while patients were alive. Conclusion. Combined biliary and duodenal stenting seems to be safe and effective in palliation of inoperable malignant biliary and duodenal obstruction.
