[Prolapsed malignant polyp of the stomach causing acute pancreatitis].

Polyps of the stomach are rare lesions with an incidence between 1.7% and 3.9%. Until now, most cases were asymptomatic and found during endoscopic examination. Only three cases of prolapsing gastric polyps causing acute pancreatitis have been reported. Prolapsed polyps of the stomach should be included in the differential diagnosis of secondary pancreatitis. If endoscopic polypectomy is impossible, surgical treatment is necessary. In case early gastric cancer of the mucosa is detected in a polyp, limited surgery is possible. Otherwise, gastrectomy with lymphadenectomy of the D2 compartment is required
