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.

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%

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.

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.

A 70-year-old man was admitted to our institution due to aggravation of blood-sugar level control and because an abdominal CT showed dilatation of the main pancreatic duct. Upper gastrointestinal endoscopy revealed a flat elevated tumor with central ulceration in the second portion of the duodenum. Subsequent duodenoscopy for a more detailed examination showed that the tumor had originated in the minor duodenal papilla. A biopsy specimen showed moderately differentiated adenocarcinoma. Endoscopic retrograde pancreatography via the major duodenal papilla revealed a slightly dilated main pancreatic duct and obstruction of the accessory pancreatic duct. Endoscopic ultrasonography showed a hypoechoic mass in the minor duodenal papilla with retention of the muscularis propria of the duodenum. These findings suggest that the tumor existed only to a limited extent in the minor duodenal papilla, and that the tumor did not infiltrate into the pancreas. For treatment, pylorus-preserving pancreatoduodenectomy was performed, and histological findings revealed a well-differentiated adenocarcinoma that originated in the minor duodenal papilla. Primary adenocarcinoma of the minor duodenal papilla is extremely rare. Our case is the first report of primary adenocarcinoma of the minor duodenal papilla at an early stage with no infiltration into muscularis propria of the duodenum and pancreas.

With the widespread use of radiologic modalities such as ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI), cystic neoplasms of the pancreas are being increasingly detected; however, developing an accurate characterization and making a differential diagnosis are difficult because of their overlapping morphologic characteristics. Serous cyst adenoma is a common benign neoplasm that is typically observed as a multi-cystic mass or lobulated cyst with or without internal septation. In comparison, mucinous cystic neoplasms appear as smooth cystic tumors with or without internal septation. Finally, intraductal papillary mucinous neoplasms of the pancreas are pleomorphic cystic lesions or clubbed fingerlike tubular structures. These typical imaging findings can help clinicians differentiate cystic neoplasms of the pancreas.

Pancreatic tumor is one of the most difficult diseases to diagnose and treat because of its anatomical location and characteristics. Recently, there have been several innovative trials on the treatment of pancreatic tumors using endoscopic ultrasound (EUS) because it allows selective access to the difficult to reach target organ along the gastrointestinal tract and can differentiate vessels by color Doppler. Among these trials, several have investigated EUS-guided ethanol lavage with or without paclitaxel for pancreatic cystic tumors. These studies show a 33% to 79% complete resolution rate with a favorable safety profile. Compared to EUS-guided ethanol lavage for pancreatic cystic tumors, EUS-guided radiofrequency ablation is considered a less invasive treatment method for pancreatic cancer. Although there are still several difficulties and concerns about complications, one clinical study reported 72.8% feasibility with favorable safety, and therefore, we anticipate the results of ongoing studies with these new less invasive techniques.

59 cases of pancreatic ultrasonography, proven by clinically, radiologically or pathologically, were analyzedand the results are as follows; 1. Enchogenecity of pancreatic cancer was low echogenic in 27 cases, highechogenic in 2 cases and had similar echogenecity in 3 cases, compared with liver. 2. There were 10 cases of livermetastasis of pancreas malignancy and the metastasis was demonstrated in 7 cases by ultrasonography. Theechogenecity of liver metastasis was low in 6 of 7 cases. 3. In 14 cases of pesudocyst, inflammatory changes inthe portion other than pseudocyst were demonstrated in 5 cases. 4. The localized enlargement of pancreas head wasdemonstrated in 3 cases of pancreatitis of 10 cases.

Laparoscopic approaches are increasingly used in pancreatic surgery. In the treatment of neuroendocrine tumors (NETs) of the pancreas, enucleation is one of the recommended surgery. Although many clinical experiences have reported the safety and efficacy of laparoscopic enucleation of functioning NETs, such as insulinomas, few reports have explored such treatment for non-functioning NETs. Here, we present a case of 70-year old female patient who underwent successful laparoscopic enucleation of a nonfunctioning NET located in the body of the pancreas.

BACKGROUND: Solid and papillary neoplasms of the pancreas are very rare tumors that occur predominantly in young women. Most of them are diagnosed because of their large sizes and because they are present with an asymptomatic abdominal mass. Most reports indicate that these large palpable, abdominal masses occur in females in their second and third decades of life. Only a few cases of solid and papillary epithelial neoplasms of the pancreas have been reported. METHOD: Here in, eight cases were reviewed which were treated at the Department of Surgery, Catholic University Medical College affiliated hospital from 1988 to 1996. RESULT: The diagnosis is often implied by radiologic examination with ultrasonography, UGI, ERCP, and computed tomography. Most cases showed well-encapsulated, round, or lobulated masses consisting of both cystic and solid areas. The hallmark histologic pattern of this tumor is a solid and papillary epithelial pattern in a pancreatic neoplasm. There is no specific marker for this neoplasm which could elucidate the obscure histogenetic origin and the phenotypic differentiation. Concluion: Therefore, surgical excision is the primary form of treatment and has favorable results.
