A comparative descriptive study was carried out on 80 patients diagnosed as pancrea head tumors. Ultrasound results were evaluated through operated and histopathological outcomes. Ultrasound diagnosis reached 96.1% of sensivity and 92.5% of accurracy, concerning the localization of the tumors the accuracy was 68%. Ultrasound sensitivity in the identification of the signs of infiltration in the neighbour tissues, in blood vessels, in gland was 12.5%, 11.8% and 8.8% respectively.

Pancreatic cancer is popular, in our report from 1997 to 1999 in Cho Ray hospital and university of medicine and pharmacy polyclinic, there are 213 patients of which 146 to be operated. There is 54.8% of patients over 59 yeas old. Male is in 58.9% of patients and female is in 41.1% of patients. Predominant symptoms included: abdominal pain (72.6%), jaundice (67.1%), abdominal mass (41.3%). Average total bilirubinemia concentration is 12.3 mg%, average concentration of direct bilirubin direct is 8.2 mg%. Ultrasound diagnosis is correct in 58.2% and CT in 59% of pancreatic cancer. Exact preoperative diagnosis in pancreatic cancer is 76.7% (stage 3) and stage 4 (74.7%). Pancreatic cancer is usually in the head and ampulary of the Vater (78.7%). Curative surgical treatment only indicated for 15.8%, other is palliative surgical treatment. Bilioenterostomy is usually performed by way of cholecystoenterostomy in 64 patients and choledoenterostomy in 32 patients. There are only 3 patients died to be reported

Endoscopic ultrasonography (EUS), one of the imaging diagnosis technique used in many countries in the world, has been first applied in Vietnam recently. This method has high value in diagnosis of the upper gastrointestinal tract, particularly of pancreatic diseases. We used EUS with sector scan transducer in 30 patients. Who were suspected to have pancreatic tumors. Result of surgery and histopathological examination of 22 patients (who accepted to have operation) are considered as the gold standard for determining the accuracy of EUS. 30 patients was 15 to 90 years old, mean age: 57.2 Male: 21/30 -70%, female: 9/30 = 30%. The results following: the accuracy of EUS is 19/22 cases (about 85%), the majority of pancreatic tumors was located in the head 14/19 (about 74%), smallest tumor is 1.4-1.5cm, invasion in to duodenum, portal vein, and lymph nodes in some cases.

From April 1998 to June 2001, ultrasound had diagnosed the tumors at the pancrea head in 80 patients and they were operated at Viet Duc Hospital. Among these subjects, there were 43 tumors of pancrea head, 14 tumors of inferior part of common bile duct, 18 tumors ooffvater ampulla, 2 tumors of duodenal, 2 chronical pancreatitis and 1 unspecific fibroma of liver external bile duct. Among 77 patients of tumor of pancrea head definitely diagnosed, there are 3 falsely positive cases and 3 negative cases by ultrasound. In 48 patients invasive structures in vessal bundle of superior mesenteriolum were diagnosed by surgery. Thus detecting pancrea head tumors, ultrasonic technique is a convenient and simple method with a sensibility of 96.1%

Pancreatic cystic neoplasm is a clinically challenging entity. Its incidence estimated up to 45% of the general population. The biological behavior ranges from benign to malignant disease. The strategy for pancreatic cystic neoplasm could be to prevent progression to pancreatic cancer while minimizing the costs. The first step for the correct management is correct diagnosis. In this paper, the radiological differential diagnosis of them will be described.

Cystic neoplasm of the pancreas is a relatively uncommon condition covering a wide spectrum of pathology. The increasing incidence as a result of routine imaging tests in asymptomatic patients presents a diagnostic and therapeutic problem to the clinician. This paper discusses the role of the various investigative modalities in the management of cystic neoplasia of the pancreas.

Several reports have described the usefulness of tumor markers detected in pancreatic juice for diagnosis of pancreatic cancer. We performed this study to evaluate the usefulness of tumor markers in pure pancreatic juice collected by duodenoscopic cannulation of pancreatic duct before and after injection of secretin. From April 1993 to July 1995, 8 cases of pancreatic cancer, 5 cases of benign pancreatic lesions, and 5 cases of benign biliary diseases without pancreatic lesion were involved. CEA and CA 19-9 immunoreactivity were measured by radioimmunoassay. Concentrations of CA 19-9 in pure pancreatic juice were significantly higher in patients with pancreatic cancer(median value; 3582, range 88.4-10410 IU/ml) than in control patients(median value 231, range 30.4-682 IU/ml)(p<0.05). Concentrations of CEA in pure pancreatic juice were not significantly different between patients with pancreatic cancer(median value: 6,5, range 1.0-152ng/ml) and control patients(median value: 4.0, range 1-17.2 ng/ml)(p>0.05). There was no significant correlation between levels of CA19-9, CEA in pancreatic juice and those levels in serum. The amounts of juice collected by duodenoscopic cannulation in patients with pancreatic cancer were 1.5+/- 0.9ml during 5 minutes before infusion of secretin, 11.3+/- 3.9ml, 10.8+/- 4.0ml, 10.6+/- 4.0ml in 5 minute interval after infusion of secretin. These results indicated that measurement of CA19-9 in pure pancreatic juice may be used as a marker for pancreatic cancer. Adequate amount of pancreatic juice was collected by duodenoscopic cannulation for evaluation of tumor marker, enzyme studies and cytology.
