Perforation of the medial aspect of the 2nd portion of the duodenum. Reactive inflammation of the 2nd and proximal 3rd portion of the duodenum.
Air and fluid are tracking in the retroperitoneum. Specifically, it is in the anterior pararenal space (anterior margin = peritoneum, posterior margin = anterior renal/Gerota fascia).
PRE/POST OPERATIVE DIAGNOSIS:
Perforated duodenal ulcer.
- Exploratory laparotomy.
- Open cholecystectomy.
- Pyloric exclusion.
- Placement of retrograde duodenostomy tube.
- Gastrojejunostomy creation.
- Gastrostomy tube placement.
- Jejunostomy tube placement.
- Creation and mobilization of omental flap
Duodenal perforation at the medial aspect of the second to third portion of the duodenum distal to the ampulla with gross spillage of bile that tracked down the retroperitoneal space.
DETAILS OF THE PROCEDURE (relevant excerpts only):
...we were able to identify the duodenum. There was gross spillage and staining of bile in this area. This was then suctioned. We were able to identify the duodenum and bluntly dissected the duodenum, the second and third portion. We were able to identify a perforation to the duodenum on the medial aspect, kind of the transition between the second and third portions of the duodenum that appeared distal to the ampulla. There was gross spillage of bile that then also tracked down into the right colic gutter retroperitoneal space that we were able to suction up. We then planned to do a pyloric exclusion given the proximity of his gallbladder and need to take down the hepatogastric ligaments. We performed an open cholecystectomy...
This case provides a good review of retroperitoneal anatomy. The perforated air and fluid track in the anterior pararenal space. Notice how most of the oral contrast did not spill through the ulcer defect. The ulcer crater/defect can be well seen on the coronal reformatted images.
