“…With the improvement of sonographic equipment and scanning techniques over recent years, the accuracy has increased, ranging from 92-95% in determining the level and 71-88% in identifying the cause of obstruction [7,8]. Regarding the diagnosis of carcinoma of the ampulla of Vater, few papers have been published, and the role of sonography has been reported as unfavorable and discouraging [9][10][11][12][13]. According to those papers, sonography failed to disclose the tumors or failed to distinguish the carcinoma of the ampulla of Vater from pancreatic carcinoma.…”

Twenty patients with carcinoma of the ampulla of Vater were studied with sonography (N = 9) or both sonography and CT (N = 11). The tumor was shown by sonography in 16 patients (80%) as a small, round or oval, fairly well delineated mass in between the dilated distal common bile duct and duodenum which was delineated owing to luminal fluid or gas (N = 13); or as a polypoid mass within the dilated distal common bile duct resulting in abrupt obstruction (N = 3). In the remaining four patients, the mass was not delineated. Bile ducts were dilated down to the level of mass or ampullary region in all cases (100%), while the pancreatic duct was dilated in five cases (45%). We believe that sonography is the technique of initial choice in the diagnosis of carcinoma of the ampulla of Vater by identifying the mass at the distal end of the dilated common bile duct and/or pancreatic duct.

Gallbladder emptying studies using ultrasonography were performed on ten normal dogs, one normal control dog, three dogs with biliary obstruction and three dogs with nonobstructive hepatobiliary disease. An intravenous bolus of a synthetic cholecystokinin was used to induce emptying. The normal canine gallbladder emptied at least 40% of its volume within one hour of synthetic cholecystokinin (0.04 Fg/kg) administration. Maximum response was seen within 5 to 20 minutes. The gallbladder in icteric dogs with nonobstructive hepatobiliary disease (1 cholecystitis, 1 cholangitis, 1 cholangiohepatitis) also emptied at least 40% of its volume within one hour. The obstructed gallbladder (1 chronic pancreatitis, 1 acute pancreatitis, 1 pancreatic mass) emptied less than 20% within one hour. A significant difference (p > 0.05) in the maximum percent gallbladder emptying was found between the dogs with biliary obstruction and nonobstructed, icteric dogs. No side effects to the synthetic cholecystokinin were observed.

Ultrasound and Hypotonic Duodenography in Biliary Obstruction

Abstract: Ultrasound examination and hypotonic duodenography were performed in 25 patients with obstructive jaundice. The diagnostic value of both methods with special reference to tumors in the head of the pancreas is discussed.
