Endoluminal closure of an unrecognized penetrating stab wound of the duodenum with endoscopic band ligation: A case report

Figure 1 Abdominal computed tomogrpahy. A: Preoperative abdominal computed tomogrpahy (CT) shows paraduodenal fluid collection and transverse colon and small bowel herniation from the abdominal stab wound; B: Postoperative abdominopelvic CT shows extravasation of the contrast medium in the third portion of the duoenum (arrow).

Figure 2 Endoscopy showed active bleeding with a perforation in the third portion of the duodenum. The cap-fitted endoscopy enabled closer observation of the bleeding site.

Figure 3 Endoscopy results. A: Endoscopic band ligation was used to make a mushroom-like area of mucosa to obtain complete closure. Additional band ligation was performed to get a more stable anchor; B: Follow-up endoscopy 9 d later showed a healing ulcer at the previous site of bleeding.
