Prospective assessment of probe‐based confocal laser endomicroscopy under direct cholangioscopic visualization for biliary strictures that could not be definitively diagnosed using endoscopic retrograde cholangiopancreatography (with video)

DEN Open, Volume 5, Issue 1, April 2025.
Abstract The definitive diagnosis of patients with indeterminate biliary strictures remains challenging. Probe‐based confocal laser endomicroscopy (pCLE) provides real‐time histological assessment of bile duct tissues. Since no previous studies have evaluated the efficacy of pCLE under direct cholangioscopic visualization for biliary strictures that ...

Efficacy and safety of a novel polytetrafluoroethylene‐coated self‐expandable metal stent for distal malignant biliary obstruction

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Background Stent migration and sludge formation remain significant problems associated with covered self‐expandable metal stents (CSEMSs). The EGIS biliary stent fully covered flare type (EGIS biliary stent), a new type of polytetrafluoroethylene‐coated self‐expandable metal stent with low axial force and an anti‐migration system, was ...

Perforation of the bile duct caused by endoscopic papillary large balloon dilation: A case report

DEN Open, Volume 5, Issue 1, April 2025.
Abstract The patient was a woman in her 70s with multiple large biliary stones. Lithotripsy was attempted after endoscopic papillary large balloon dilatation. During balloon dilation, inflator resistance, and body movement due to patient pain were observed, and maximum pressure was required for the disappearance of the balloon waist.

Endoscopic ultrasound‐guided choledochoduodenostomy versus hepaticogastrostomy combined with gastroenterostomy in malignant double obstruction (CABRIOLET_Pro): A prospective comparative study

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Objectives Malignant double obstruction, defined as the simultaneous presence of biliary and gastric outlet obstruction, represents a challenging clinical scenario. Previous retrospective experiences have demonstrated shorter dysfunction‐free survival (DyFS) of endoscopic ultrasound‐guided choledochoduodenostomy (EUS‐CDS) versus EUS ...

Recurrence rate of cholecystitis after initial gallbladder stenting versus secondary gallbladder stenting: A propensity score matching study

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Objective Limitations are sometimes encountered in the application of laparoscopic cholecystectomy to the treatment of acute cholecystitis. Endoscopic gallbladder stenting (EGBS) has emerged as an additional option. However, the long‐term stent patency remains an issue.

Operative Cholangiography

Australian and New Zealand Journal of Surgery, 1970
Operative cholangiography was first used by Mirizzi in 1932, but still has not gained general acceptance by surgeons. With these facts in mind, this article reviews 31 cholecystectomies, 20 having been performed by the author, in which operative cholangiography was used, and discusses its technique, difficulties and results.

Post‐endoscopic sphincterotomy delayed bleeding occurs in patients with just 1‐day interruption of direct oral anticoagulants or hemodialysis

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Objective Endoscopic sphincterotomy (EST), especially when anticoagulants are used, carries a significant risk of delayed bleeding. However, the relationship between the use of antithrombotic agents, including direct oral anticoagulants, and post‐EST bleeding remains unclear.

Feasibility of endoscopic ultrasound‐guided hepaticogastrostomy using a novel long balloon catheter

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Objectives Recently, a novel long balloon catheter for tract dilation in endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) was developed. The balloon measures 6 cm in length, which enables one‐step tract dilation of the gastric wall, liver parenchyma, and bile duct wall, contributing to shorter procedure times and reduced bile leakage.

The First Single‐Port Robotic‐Assisted Excision of Choledochal Cyst and Hepaticojejunostomy in Children

The International Journal of Medical Robotics and Computer Assisted Surgery, Volume 21, Issue 2, April 2025.
ABSTRACT Background Choledochal cysts are congenital anomalies requiring surgical intervention, typical excision and hepaticojejunostomy. The da Vinci single‐port (SP) robotic system offers a minimally invasive approach with potential benefits for paediatric patients.
