Treatment outcomes of biliary intervention using standard type and short type single balloon enteroscope in patients with surgically altered gastrointestinal anatomy

Abstract

Treatment outcomes of biliary intervention using standard and short type single balloon enteroscope (SBE) was compared in patients with surgically altered gastrointestinal anatomy (SAGA). Seventy-three and one hundred ten cases were included in a standard and short group. More cases of Roux-en-Y anastomosis with prior gastrectomy and of malignant biliary obstruction were included in a short group. The success rate of reaching the target site was improved and the time of reaching the target site was shorter in a short group. The success rate of biliary cannulation was also better in a short group, though there were no difference in the success rates of ERCP-related intervention between two groups. The overall success rate was superior and the overall procedure time was shorter in a short group. Our study showed that the treatment outcomes were improved using a short type SBE when performing biliary intervention in patients with SAGA.
