 Case: a 66-year-old woman.

 Chief complaints: nausea and vomiting.

 Past history: At one time the feces was positive for ascaris ova.

 Familial history: non-contributory.

 Present history: Since about two weeks before she had slight epigastrial pain along with nausea and vomiting, and on May 6, 1972, she visited the Biwako Gastroenterological Hospital.

 Status praesens: No remarkable changes except tenderness in the epigastrial region.

 General examinations: Except ascaris ova in the feces various examinations including the blood, liver function tests were within normal limits.

 Course of the diagnosis: Upper gastrointestinal x-ray series showed no abnormality in the stomach, and swollen papillary region in the duodenum. As both peroral and intravenous cholecystography disclosed nothing unusual, endoscopic pancreatocholangiography was attempted. The papillary region of the duodenum was markedly swollen, with erosions and bleeding on the papilla of Vater (Fig. 1 and 2).

Biopsy of the papilla revealed no malignant changes. Diagnosis then was papillitis (Fig. 3). Cannulation into the papilla was not diffcult, and first the pancreatic duct was opacified (Fig. 4), followed by positive cholangiography (Fig. 5 and 6). Findings of the visualized ducts led us to a diagnosis of biliary ascariasis associated with chronic pancreatitis.

 Findings at operation: Dilatation of the common bile duct was pronounced. By incision an alive ascaris and another dead one were taken out of the common bile dudt. Incidentally, two small stones were seen in the gallbladder, so that cholecystectomy was performed (Fig. 7). The pancreas was cirrhotic, but no malignant changes were observed. Findings obtained were thus indicative of advanced chronic pancreatitis.

 Final diagnosis: 1) bile duct ascariasis.2) cholelithiasis. 3) chronic pancreatitis. 4) duodenal papillitis.
