Anchor-wire technique for multiple plastic biliary stents to prevent stent dislocation.

In endoscopic placement of multiple plastic biliary stents (PBSs), we sometimes experience proximal dislocation of the first PBS at the time of subsequent PBS insertion. We describe the case of a 79-year-old male with obstructive jaundice caused by cholangiocarcinoma who needed to receive multiple PBS placements for management of cholangitis. Although proximal dislocation of the first PBS was observed, we prevented the dislocation via our technique of using guidewire inserted from the distal end of the first PBS to the side hole as the anchor-wire.

Assessment of the risk factors for colonic diverticular hemorrhage.

Purpose: Colonic diverticulosis, although usually asymptomatic, sometimes causes diverticular hemorrhage. Studies about risk factors, other than nonsteroidal anti-inflammatory drugs, for colonic diverticular hemorrhage are limited. We conducted the present study to elucidate their significance as a risk factor.

Involvement of the biliary system in autoimmune pancreatitis: a follow-up study.

Background & Aims: The aim of this study was to define the bile duct changes associated with autoimmune pancreatitis.

Methods: Eight patients with autoimmune pancreatitis were followed for a mean of 4 years. The clinical features of these patients, including extrapancreatic bile duct changes, were examined by using biochemical parameters and several imaging modalities.
