THREE CASES OF ADULT ANNULAR PANCREAS DIAGNOSED BY ENDOSCOPIC RETROGRADE CHOLANGIO-PANCREATOGRAPHY

Abstract

Annular pancreas has been diagnosed by chance at the gastroenterological examination. Recently it has been made possible to elucidate the pathological features of annular pancreas and to determine the therapeutic plan by the progress of diagnostic procedures, especially Endoscopic Retrograde Cholangio-Pancreatography (ERCP). In a few years, three cases of annular pancreas were diagnosed by ERCP in our institute. Case 1. A 47-year-old male complained of left hypochondralgia and back pain. The main pancreatic duct surrouding the second portion of the duodenum was revealed by ERCP. In the course, pancreatic calculi, chronic relapsing pancreatitis, pancreatic cyst and duodenal ulcer were obseved complicated. Case 2. A 76-year old male complained of diarrhea. A branch of the Wirsung's duct surrounding the second portion of the duodenum was revealed by ERCP. The main and annular ducts showed moderate change. Case 3. A 47-year old female suffering from malignant lymphoma complained of left hypochondralgia. The branch of the Wirsung's duct surrounding the second portion of the duodenum was revealed by ERCP, and minimal change of main pancreatic duct was observed.
