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.
