Fig. 1(A) No bleeding occurred after endoscopic sphincterotomy. (B) A black pigment stone is successfully removed using a basket and (C) immediate complications are not observed after the procedure.
Fig. 2(A) Initial abdomen computed tomography (CT) reveals a large duodenal diverticulum (arrowheads) on the lateral wall of duodenum second portion. (B) Abdominal CT performed the next day after endoscopic retrograde pancreaticoduodenography (ERCP) shows severe edematous wall thickening of the duodenum (white arrows). Localized focal low-attenuated lesion suggesting hematoma is also observed at the periampullary area (black arrows). (C) Follow-up abdominal CT performed 11 days after ERCP demonstrates considerably improved edematous wall thickening of the duodenum and resolved focal low-attenuated lesion at the periampullary area.
Fig. 3(A) Endoscopic examination performed the day after endoscopic retrograde cholangiopancreatography (ERCP) demonstrates diffusely edematous duodenal mucosa with linear ulcerations and a large bulging lesion suggestive of hematoma (black arrows) distal to the ampulla of Vater (arrowhead). (B) Follow-up endoscopy performed 8 days after ERCP shows much improved duodenal wall edema with a large ulcer where the hematoma had been (white arrow).
