Gastroduodenal Fistula Following Endoscopic Ultrasound-Guided Gallbladder Drainage Using a Double-Pigtail Plastic Stent.

Hirai and colleagues reported delayed gastroduodenal fistula formation 6 months after EUS-guided gallbladder drainage with a double-pigtail plastic stent. Persistent stent pressure from gallbladder contraction may cause bowel injury even with double-pigtail stents. Careful stent selection and positioning, together with regular imaging follow-up, may reduce injury and detect delayed complications.
