TECHNICAL TIPS FOR ENDOSCOPIC TRANSPAPILLARY GALLBLADDER DRAINAGE IN PATIENTS WITH ACUTE CHOLECYSTITIS

Abstract

Drainage techniques for acute cholecystitis include percutaneous transhepatic drainage (PTGBD), endoscopic transpapillary gallbladder drainage (ETGBD), and endoscopic ultrasound-guided gallbladder drainage (EUS-GBD). ETGBD is a non-puncture procedure through a physiological route; hence, it can be performed on patients with bleeding tendencies or ascites. However, the technical success rate of ETGBD is inferior to that of PTGBD and EUS-GBD owing to the technical difficulty of selective cannulation to the cystic duct. A safe and successful ETGBD requires mastery of the basic technique and ability to troubleshoot during difficult cases.
