Filter by: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.
It is designed to monitor the efficacy of nasal cannula or hıgh-flow nasal oxygen in geriatric patients for endoscopıc retrograde cholangıopancreatography procedures. The aim of the study is to evaluate the efficacy and safety of oxygen support obtained with low-flow nasal cannula and hıgh-flow nasal oxygen during endoscopıc retrograde cholangıopancreatography in the patient group at risk for adverse respiratory events. We hypothesized that high-flow nasal oxygen administration can prevent adverse respiratory events such as deep sedation and patient position that may endanger the airway safety of patients, and reduce the problems in cardiac and hemodynamic parameters that may develop.
Malignant obstructions of the bile duct are not rare. The most common and accepted method for biliary drainage is endoscopic stent placement. There are three types of metal stents: fully covered (FC), partially covered (PC) and uncovered (U). PC-SEMS have been recently introduced and compared to FC-SEMS they seem to have a lower risk of migration, although data in the literature are discordant. Therefore the investigators will randomize the participants with biliary obstruction in 2 groups according to the type of stent used: PC-SEMS or U-SEMS. After metallic biliary stent insertion, enrolled patients will be followed for 12 months.
