Side-by-side versus stent-in-stent technique for stent deployment during systemic chemotherapy in biliary tract cancer patients with malignant hilar biliary obstruction.

ABSTRACT:

Objectives

With the improved prognosis of patients with biliary tract cancer (BTC) owing to advances in chemotherapy, long-term stent patency has become an important goal in patients undergoing biliary stent placement. We compared the duration of stent patency between unresectable BTC patients undergoing multi-stenting for malignant hilar biliary obstruction by the side-by-side (SBS) and stent-in-stent (SIS) techniques during systemic chemotherapy.

Methods

We retrospectively evaluated the data of 62 unresectable BTC patients who underwent multi-stenting before the first or second cycle of first-line chemotherapy. Stent deployment was performed by the SBS technique in 40 patients (SBS group) and by the SIS technique in 22 patients (SIS group).
