 - Background
/Aims: Endoscopic biliary drainage is the gold standard treatment for cholangitis. The two methods of biliary drainage are endoscopic biliary stenting and nasobiliary drainage. A novel integrated outside biliary stent and nasobiliary drainage catheter system (UMIDAS NB stent; Olympus Medical Systems) was recently developed. In this study, we evaluated the efficacy of this stent in the treatment of cholangitis caused by common bile duct stones or distal bile duct strictures.
Methods
We conducted a retrospective pilot study by examining the medical records of patients who required endoscopic biliary drainage for cholangitis due to common bile duct stones or distal bile duct strictures, and who were treated with a UMIDAS NB stent, between December 2021 and July 2022.
Results
Records of 54 consecutive patients were reviewed. Technical and clinical success rates were 47/54 (87.0%) and 52/54 (96.3%), respectively. Adverse events were observed in 12 patients, with six patients experiencing pancreatitis as an adverse event, following endoscopic retrograde cholangiopancreatography (ERCP). Regarding late adverse events, five cases of biliary stent migration into the bile duct were observed. Disease-related death occurred in one patient.
Conclusions
The outside-type UMIDAS NB stent is an efficacious new method for biliary drainage and can be applied to many indications.

Abstract

- A 50-year-old woman had a percutaneous endoscopic gastrostomy (PEG) tube placed after surgery for pharyngeal cancer. After 21 months, the PEG tube was removed due to improvement of per-oral ingestion. She had taken prednisolone for 31 years for systemic lupus erythematosus. The post-PEG fistula did not close spontaneously. The cause of the fistula was slow wound healing and gastrostomy site inflammation due to long-term steroid therapy. We were able to close the fistula with an over-the-scope clipping (OTSC) system. This case suggests that OTSC is useful for closing persistent post-PEG fistulas in patients receiving long-term prednisolone therapy.
