Figure 1 Initial abdominal computed tomography and endoscopic findings during endoscopic retrograde cholangiopancreatography. A: Computed tomography showed a small common bile duct stone (thin white arrow); B: During endoscopic retrograde cholangiopancreatography, a 10 mm-sized perforation developed in the lateral wall of the duodenal bulb during inadvertent rapid withdrawal of the duodenoscope (thick black arrow); C and D: Multiple hemoclips and an endoloop were immediately applied for the defect closure.
