From: Two cases of a perforated duodenal diverticulum after gastrectomy with Roux-en-Y reconstruction
Computed tomography of case 1 with a perforated duodenal diverticulum and surgical findings. Abdominal contrast-enhanced CT (a, axial plane) showed an extraluminal fluid collection with gas (yellow arrow) surrounding the duodenum. Coronal plane (b) showed that an abscess (yellow arrows) was suspected around the second and third parts of the duodenum (D). A retroperitoneal abscess (yellow arrow) behind the second part of the duodenum (D) was found after performing Kocher maneuver (c). The schema (d) showed that a white-yellow retroperitoneal abscess (black arrow) was seen behind the perforated duodenal diverticulum (black arrowhead). And the right kidney was seen after performing Kocher maneuver
