Endoscopic pancreatography in chronic pancreatitis of the tropics

The ERCP findings in 13 patients with chronic pancreatitis of the tropics are reported. 7 of the patients had pancreatic calculi on plain film of abdomen and 6 had no calcification. The changes observed in the pancreatograms were tortuosity, dilatation, stenosis, obstruction, cyst formation and presence of calculi in the main pancreatic ducts and their finer branches. The calcific variety showed a greater degree of ductal derangement compared to the non-calcific variety. The common bile duct was normal in all the patients. The pancreatographic changes observed are similar to those described in the alcoholic and other varieties of chronic pancreatitis.
