• Stool screening for gallstones and ultrasound monitoring of diameter changes of the biliary and pancreatic duct were performed in 129 patients with choledocholithiasis. Gallstone migration was found in 44 patients, all of whom were operated on electively. At surgery, acute pancreatic lesions were found in 16 patients; in the remaining 28 there was no evidence of pancreatic inflammation. There were no significant differences among patients in both groups regarding sex, age, stone size, shape or number found in stools, interval between admission and migration, or the presence of a dilated pancreatic duct before migration. Pancreatic duct reflux, however, was significantly more frequent in cholangiograms of patients with acute pancreatitis, implying that a common channel may be a major factor relating to acute pancreatitis in patients with migrating gallstones.
