A case of successful conservative therapy for a perforated duodenal diverticulum after barium gastrography

Abstract

A 40-year-old female patient visited the hospital because of a stomachache and vomiting 3 days after barium gastrography. The abdominal computed tomography scan indicated a diverticulum around the third part of the duodenum, high-density area inside the diverticulum, and fluid collection and increased fat tissue concentration around the retroperitoneum. The patient was diagnosed as having a retroperitoneal abscess due to a perforated duodenal diverticulum, and she was treated conservatively because the extent of the abscess was limited and her general condition was not poor.
In many similar cases, surgical therapy is selected, but this patient achieved complete recovery with conservative treatment. We experienced a rare case of a perforated duodenal diverticulum after barium gastrography.
