Annular pancreas in the adult is a rare anatomic anomaly which is detected by symptoms based on chronic partial obstruction of the duodenum. Four patients with annular pancreas were treated at our clinic during the past 5 years. Of them, 3 patients were male and one was female. The age range was 40 to 44 years. The annulus was found to be a complete ring in one patient, while in the remaining patients only a partial one was present. In all patients, the annulus was situated in the region of the second part of the duodenum. These patients had complications such as peptic ulceration, cholelithiasis, and others. Therefore, the symptoms of our series were influenced by the ones that were seen in the complications. The diagnosis was dependent exclusively on the findings of upper gastrointestinal barium x-ray studies, especially hypotonic duodenography. Surgical treatment of these patients consisted of a partial gastrectomy (Billroth II), a partial resection of the annulus, and others. These patients had a good prognosis after operation.It is concluded that hypotonic duodenography is a beneficial way for the diagnosis of annular pancreas, and that the operative treatment should consist of relief of any obstruction to the duodenum by a procedure suitable to each patient.
