Quality of Life Assessment Between Internal Endoscopic Versus Percutaneous Drainage in Biliary Obstruction

The aim of this study is to compare the quality of life in subjects with benign and malignant biliary obstruction who have or will undergo endoscopic retrograde cholangiopancreatography (ERCP) and/or percutaneous trans-hepatic biliary drainage (PTBD).

12-mm Partial Covered Versus Bare Self-Expandable Metallic Stents for Malignant Distal Biliary Obstruction

Metallic stents are commonly used for biliary drainage in patients with unresectable malignant distal biliary obstruction. However, it is unclear whether a 12-mm partially covered self-expandable metallic stent or a 12-mm bare self-expandable metallic stent provides better effectiveness and safety. This prospective, randomized clinical trial will compare these two stent types in adult patients who have already undergone percutaneous transhepatic biliary drainage (PTBD) and are scheduled for metallic stent placement through the existing PTBD tract. A total of 60 participants will be enrolled. After stent placement, participants will be followed for 12 months, with assessments at 3, 6, and 12 months. The study will evaluate recurrent biliary obstruction, stent patency duration, reintervention, overall survival, and procedure-related complications. The results are expected to provide evidence for selecting the most appropriate 12-mm metallic stent for patients with unresectable malignant distal biliary obstruction.

Prospective Registry Of Therapeutic EndoscopiC ulTrasound

This registry aims to analyze long-term outcomes of therapeutic EUS (T-EUS) procedures, as well as to describe clinical and technical variables potentially predicting clinical success or adverse events, for a better selection of ideal candidates. The study also includes standard alternatives to T-EUS procedures for outcomes comparison.

Comparative Efficacy Of Intraductal Antibiotic During ERCP In Acute Cholangitis

Does intraductal administration of antibiotics during endoscopic retrograde cholangiopancreatography (ERCP), in addition to standard systemic antibiotic therapy, improve clinical outcomes in patients with acute cholangitis compared with standard systemic antibiotic therapy alone?

Safety and Efficacy of Mechanical Versus Electrocautery Dilator for EUS-guided Biliary Drainage (MED-BD)

The purpose of this study is to investigate the likelihood of post-dilation bleeding using mechanical or electrocautery dilation. We hypothesized that the risk of bleeding is lower in the mechanical group.

Prevention of Acute Cholecystitis With ETGBD

The goal of this clinical trial is to learn about Efficacy of the ETGBD parallel insertion with fully covered self-expandable metal stent for preventing acute cholecystitis in patients with low cystic duct insertion. In this study, we hypothesized that endoscopic transpapillary gallbladder drainage (ETGBD) with parallel insertion of a fully covered self-expanding metal stent(FCSEMS) through an endoscopic biliary drainage tunnel is superior in preventing complications such as cholecystitis when the gallbladder ducts confluence within the distal third of the common bile duct. And we aimed to confirm its efficacy by comparing the frequency, severity, and rate of invasive additional procedures due to cholecystitis complications to provide evidence of clinical utility.

Gallbladder Stenting in FC-SEMS

The goal of this randomized controlled trial is to determine whether primary prophylaxis with transpapillary gallbladder drainage prevents acute cholecystitis after fully-covered self-expandable metal stents placement during endoscopic retrograde cholangiopancreatography for malignant distal biliary obstruction in patients at higher risk of post-endoscopic retrograde cholangiopancreatography acute cholecystitis. The main question it aims to answer is: Does prophylactic transpapillary gallbladder drainage reduce the rate of post-endoscopic retrograde cholangiopancreatography acute cholecystitis in high-risk patients? Researchers will compare patients who undergo transpapillary gallbladder drainage to patients without transpapillary gallbladder drainage to see if transpapillary gallbladder drainage reduces the rate of acute cholecystitis. Participants will: 1. receive or not transpapillary gallbladder drainage before fully-covered self-expandable metal stents placement 2. will be followed up at one, three, and six months to ascertain the onset of acute cholecystitis
