Rare case of duodenal perforation due to diverticulum with heterotopic pancreas: A report
A rare case of laparoscopic surgery for duodenal perforation due to a diverticulum with a heterotopic pancreas was published in the Surgical Case Reports
Heterotopic pancreas (HP) refers to the presence of abnormally located pancreatic tissue without any anatomic or vascular continuity with the main body of the pancreas. The heterotopic pancreas can occur in the gastrointestinal tract and be complicated by gastrointestinal bleeding, pancreatitis, obstruction, or malignant generation. Specifically, perforation of the gastrointestinal tract because of Heterotopic pancreas is extremely rare. Heterotopic pancreas (HP) and aberrant, ectopic, or accessory pancreas refer to the presence of pancreatic tissues outside of their normal location and without anatomic or vascular continuity with the pancreas itself
A 91-year-old woman was diagnosed with duodenal perforation, and an emergency laparoscopic operation was performed. The operative findings indicated a tumor and duodenal wall perforation. The tumor and the perforated site were resected with a linear stapler. Histopathological examination revealed the presence of Heterotopic pancreas tissue in the submucosal layer around the diverticulum without any signs of inflammation. The perforated site was not covered by Heterotopic pancreas tissues, and the duodenal wall might have been weaker than the other areas, which could have caused the internal pressure to increase and led to the perforation.
Thus, Preoperative Heterotopic pancreas diagnosis is difficult, and it is crucial to consider Heterotopic pancreas as the differential diagnosis in gastrointestinal perforations. The duodenal diverticula can be perforated due to increased internal pressure of the duodenum caused by the imbalanced localization of Heterotopic pancreas.
