13 patients with the gallbladder cancer diagnosed by ultrasound in which 6 patients received CT scanner, these images compared with the operational results and pathological anatomy. The gallbladder cancer occurred most frequently in the elderly and had the poor prognosis. The ultrasound showed the unfair thickness of gallbladder wall (66.7%) rough tumor from the posterior wall to gallbladder

Retrospective study on 194 dossiers of the patients with common bile duct stones, including 90 patients with calculi in the lower choledochus (posterior pancreas), 68 patients are examined in urgent situation and 126 patients non-urgent, 73 patients with history of abdominal surgery, 121 patients without history of abdominal surgery. All patients were diagnosed by sonography and have been operated at Viet Duc Hospital in 2 years of 1998-1999. The result shown that the sensitivity of sonography in diagnosing common bile duct stones is 95% and in diagnosing lower choledochus stones is 87.8%. Urgent or non-urgent ultrasonic examination have unconsidered influence to the sonographic value in diagnosing common bile duct stones with the sensitivity 92.6% and 97.6% respectively. The situation of abdominal surgery influences the sonographic value in diagnosing common bile ducts stones: The sensitivity is 91.8% to patients with abdominal surgery and is 91.8% to patients with abdominal surgery and is 98.3% to patients without abdominal surgery.

The ultrasound for early, right local diagnosis helps convenient operation, improves the treatment quality and reduces the mortality rate. Study on 97 patients with operation for the gallbladder stone in the central army hospital No 108 from Jan. 1993 to June 1994 received an operation by Kontrol. The corrects of ultrasound before operation for the gallbladder stone, OMC stone, inner hepatic stone and biliary ascariasis are 95%; 97.94%; 87.63%-93.84%; 92.78%-94.85%, respectively. The ultrasound only has determined dilation of bile-duct. The diagnosis of narrow of bile-duct, especially inner hepatic bile-duct remainly are limited by ultrasound.

Torsion of the gallbladder is a rare and acute abdominal condition. Even with the recent advances in radiologic imaging modalities, it is difficult to make a correct preoperative diagnosis of gallbladder torsion. We recently experienced a case of gallbladder torsion at the body portion in which an accurate preoperative diagnosis could be made on the gray scale and by using color Doppler ultrasonography. We report the imaging and operative findings with particular emphasis on the ultrasonographic "whirlpool sign".

30 patients diagnosed as gallbladder polyps by laparoscopic ultrasound of which 12 patients received operations have shown that the male/female was 1/1; the disease occurred most frequently in ages of 40-50. The gallbladder multipolyps occurred more frequently than gallbladder polyp and rate of pedicular polyps was higher than nonpedicular polyp. 36.8% of patients accompanying with other diseases such as gallbladder stone, cancer, hepatic angioma. The laparoscopic ultrasound was high precise technique for diagnosis of gallbladder polyp (11/12).

A retrospective study on 20 operated patients with gallbladder polyp and a prospective study on 2 patients with gallbladder polyp of which 10 patient operated were carried out. Results were compared with results of diagnostic ultrasound and histological tests in 30 operated patients. They have shown that the ultrasound sensitivity was 73.3%, 50% of polyps were cholesterol polyps. 9/11 cholesterol polyps were small, with diameter less than 5 mm.

Ultrasound cross-sectional prospective investigation on 16 patients with Dengue fever, showed that 15/16 cases, gall bladder wall thickness was a factor of prognosis, standard for patients with high risk of volume dropping shock related to kidney syndrome, 12/16 cases with abdominal cavity fluid, 7/16 cases there was perirenal collection of fluid, 3/16 cases of fluid subcapsular collection in the liver, pleural effusion. In addition, there may be large pancreas and spontaneous rupture of the kidney.

Cholesterol polyps are the most common cause of the polypoid lesions of the gallbladder shown by ultrasonography (US). Cholesterol polyps are usually attached to the mucosal surface of the viscus with delicate, filammentous stalks so that they can be easily detached. Recently, laparoscopic cholecystectomy has been introduced to treat various gallbladder diseases. We have experienced four patients with ultrasonographically typical gallbladder polyps, that were not detected in the pathologic specimens removed by laparoscopic cholecystectomy. In each patients, intraluminal suction preceded the laparoscopic cholecystectomy, and the suction was presumed to have resulted in the detachment of cholesterol polyps having delicated and fragile stalks.

Twenty cases of polypoid lesions of the gallbladder were reviewed. Seven were benign lesions. Among them, there were 4 (20%) adenomas and 3 (15%) adenomatous hyperplasias. All of the benign lesions were less than 1 cm in diameter. Thirteen cases involved a carcinoma of the gallbladder, of which 92% were more than 1 cm in diameter, 76.9% were over 60 years of age, and 38.5% were associated with gallstones. The accuracy of the preoperative ultrasonographic diagnosis of the polypoid lesions of the gallbladder was 80%. The spread and the size of the tumor showed a close correlation. Therefore, the size of the tumor is a vital indicator for the treatment of polypoid lesions of the gallbladder; lesions between 0.6~1 cm in diameter should be followed up by ultrasonography. An operation may be considered if stones are present. Lesions bigger than 1 cm should be resected since malignancy can not be excluded.
