Gastric polyp prolapsed into the duodenum as a rare cause of acute pancreatitis.
Mechanical gastric polyp complications are very rare occurrences most commonly related to hyperplastic polyps. We report here the case of a young woman with a 12-cm adenomatous polyp on the great curvature of the stomach diagnosed incidentally during tests for anaemia. Later, the patient was referred to hospital for recurrent emergency due to acute pancreatitis caused by the polyp prolapsing into the duodenum. A two-step treatment was undertaken: the first procedure consisted of a surgical polypectomy followed by a second-step total gastrectomy for cancer necessitated by the presence of an invasive adenocarcinoma on the polyp. This case proves malignant adenomatous polyps to be exceptionally responsible for mechanical complications such as acute pancreatitis due to polyp prolapsing into the duodenum. In such a complicated case, we recommend deferredemergency resection of the polyp followed subsequently by gastrectomy for cancer when histologically indicated.
