Incidence of biliary stricture formation after pancreaticoduodenectomy (PD) for benign and malignant periampullary disease.

“Between January 1995 and April 2003, 1595 patients underwent PD for periampullary disease (392 benign, 1203 malignant). A retrospective analysis of a prospectively collected database was performed to determine the incidence of biliary stricture after PD.”

Results: “Forty-two of the 1595 patients (2.6%) who underwent PD developed postoperative jaundice secondary to a stricture of the biliary-enteric anastomosis. There was no difference in the incidence of biliary strictures after resection for benign (n = 10, 2.6%) or malignant disease (n = 32, 2.6%). The median time to stricture formation resulting in jaundice was 13 months (range, 1–106 months) and was similar for patients with benign and malignant disease. Preoperative jaundice did not protect against biliary stricture formation. By univariate analysis, biliary strictures were associated with preoperative percutaneous biliary drainage (odds ratio [OR] = 2.11, P = 0.02) and postoperative biliary stenting (OR = 2.11, P = 0.013). Postoperative chemoradiotherapy in patients with malignant disease was not associated with stricture formation. All strictures were initially managed with percutaneous biliary balloon dilatation and stenting, and only 2 patients required redo hepaticojejunostomy. Recurrent neoplastic disease was discovered in only 3 of the 32 patients (9%) with malignant disease. All 3 of these patients had cholangiocarcinoma as their initial diagnosis.”
