What is the role of endoscopic therapy in early and late postoperative bile duct stenosis?

Introduction: The endoscopic therapy (ET) is useful for the management of benign postoperative bile duct stenosis (BPBDS) but there are only few studies available for evaluating long-term effectiveness of ET. Aim and method: Endoscopic retrograde cholangiography (ERC) and ET (sphincterotomy, balloon dilatation and stenting) were planned to be performed in 33 patients (pts) with BPBDS. After ET the cholestatic parameters and the diameter of the bile ducts defined by ultrasonography were checked every six months to 97 months on average (70–131 months). If any pathological sign was observed, the ERC was repeated. T…
