Endoscopic treatment of sphincterotomy-related biliary strictures (SRBS) by using sequental insertion of multiple stents

Background: Late complications of endoscopic biliary sphincterotomy (EBS) are orifitial stenosis (OS) and SRBS. Re-sphincterotomy is a safe treatment of OS. However, in SRBS, the narrowed distal common bile duct (CBD) segment may extend to the proximal intraduodenal part of CBD. Therefore, SRBS-related long strictures cannot be treated with repeated EBS. Aim: We evaluated the efficacy of multiple biliary stent insretion in the treatment of SRBS. Patients: In 1998, we enrolled 20 SRBS cases (female/male: 18/2; mean age: 61 years [36–81]; mean SRBS length: 12.4mm [11–20]), and followed up until 2003. Since all pat…
