Endoscopic Nasogallbladder Drainage Combined with Laparoscopic Surgery for Type I Mirizzi Syndrome with Acute Cholecystitis: A Case Series Report

Figure 2

The procedure of endoscopic nasogallbladder drainage (ENGBD). (a) Cholangiography for diagnosis through endoscopic retrograde cholangiopancreatography (ERCP). (b) Using a hydrophilic guidewire under fluoroscopy, the catheter can be inserted into the target bile duct and then the gallbladder. The guidewire was retained in the gallbladder cavity to the greatest extent possible, in order to form a circle. (c) The curved nasobiliary duct was pushed into the gallbladder along the guidewire; the guidewire was then gently removed. The head of the nasobiliary duct thus formed a circle in the gallbladder cavity.
