A Rare Fatal Bile Peritonitis after Malposition of Endoscopic Ultrasound-Guided 5-Fr Naso-Gallbladder Drainage

Endoscopic ultrasound (EUS)-guided gallbladder (GB) drainage has recently emerged as a more feasible treatment than percutaneous transhepatic GB drainage for acute cholecystitis. In EUS-guided cholecystostomies in patients with distended GBs without pericholecystic inflammation or prominent wall thickening, a needle puncture with tract dilatation is often difficult. Guidewires may slip during the insertion of thin and flexible drainage catheters, which can also cause the body portion of the catheter to be unexpectedly situated and prolonged between the GB and intestines because the non-inflamed distended GB is fluctuant. Upon fluoroscopic examination during the procedure, the position of the abnormally coiled catheter may appear to be correct in patients with a distended stomach. We experienced such an adverse event with fatal bile peritonitis in a patient with GB distension suggestive of malignant bile duct stricture. Fatal bile peritonitis then occurred. Therefore, the endoscopist should confirm the indications for cholecystostomy and determine whether a distended GB is a secondary change or acute cholecystitis.
