Postbiliary drainage rates of cholangitis are impacted by procedural technique for patients with supra-ampullary cholangiocarcinoma: A SEER-Medicare analysis.

ABSTRACT:

Background

The optimal approach to biliary drainage for patients with supra-ampullary cholangiocarcinoma remains undetermined. Violation of sphincter of Oddi results in bacterial colonization of bile ducts and may increase postdrainage infectious complications. We sought to determine if rates of cholangitis are affected by the type of drainage procedure.

Methods

We examined the Surveillance, Epidemiology, and End Results-Medicare linked database from 1991 to 2013 for cholangiocarcinoma. Biliary drainage procedures were categorized as sphincter of Oddi violating (SOV) or sphincter of Oddi preserving (SOP). Patients were stratified by resection.

Results

A total of 1914 patients were included in the final analysis. A total of 1264 patients did not undergo a postdrainage
