A cystadenoma of the pancreas within the spleen from pancreatic heterotopia is described. The tumor was located in the hilum of the spleen and completely separated from the normal pancreatic tail. This fact strongly supports the possibility that this tumor arose from pancreatic heterotopia.

A patient with massive pancreatic pleural effusion in whom the use of endoscopic retrograde cholangiopancreatography (ERCP) revealed the site of a pancreatic fistula to the pleural cavity is presented. It is suggested that with this form of pleural effusion, ERCP may aid in the selection of those patients whose lesions may be surgically correctable.

An unusual presentation of polyp of the ampulla of Vater is described. The patient initially had a chronic relapsing pancreatitis. Pancreatocholangiography revealed a tumor in the main pancreatic duct that proved to be a pedunculated polyp of the ampulla of Vater by operation. Transduodenal excision and sphincteroplasty may cure the lesion and relieve the symptoms of this disease.

Carcinoma of the duodenum, although uncommon, can be diagnosed by direct visualization, photography of the tumour and biopsy by the fibre-duodenoscope. The duodenoscopic examination may not only distinguish carcinoma of the duodenum from pancreatic carcinoma, ampullary carcinoma and secondary tumour from an adjacent organ but will also enable a correct diagnosis to be made early in the course of the disease. It is therefore suggested that duodenoscopy and biopsy will increase the resectability and 5-year survival rate.
Retrograde pancreatocholangiography was successful in 110 or 83 per cent of 133 patients suspected of having pancreatobiliary disease. Cannulation of the pancreatic duct was successful in 95 per cent of the patients suspected of having disorders of the pancreas. In 84 per cent, the biliary tree was successfully visualized among the group suspected of having disorders of the biliary tract. Dilatation of the main pancreatic duct in association with cholelithiasis and choledocholithiasis was observed in 33 and 72 percent, respectively.
