HYPOTHESIS Accurate differentiation between inflammatory and neoplastic tumors of the pancreas remains a diagnostic dilemma for surgeons. The aim of the study was to assess the utility of 2 neoplastic markers, cancer antigen (CA) 19-9 and CA 125, in the differential diagnosis of pancreatic tumors. DESIGN The patients were assigned to a malignant or benign(More)
Despite urbanization of contemporary society and limitation on the environmental areas, the threat of animal attacks on people is still an important social and medical problem. Although they usually do not have serious consequences, they are nevertheless disturbing and alarming enough to make people seek professional, medical help. The aim of this study was(More)
Inflammatory fibroid polyp is one of the chronic inflammatory diseases in the digestive tract, which often mimics the submucosal tumor. Precise diagnosis is possible after removal of the detected lesion. Endoscopic removal is recommended as a safe and efficient method of the treatment. In this report the authors present a case of inflammatory fibroid polyp(More)
Inflammatory and neoplastic tumors of the pancreas still remain a diagnostic dilemma for a surgeon mainly due to subtle differences between these two sorts of tumors. The aim of the study was to assess the utility of the serum marker, CA 19-9, in the differential diagnosis of pancreatic tumors. 150 patients with heterogenic pancreatic lesion were diagnosed(More)
The aim of this paper is to evaluate the sensitivity and specificity of ultrasound and computed tomography imaging in necrotizing acute pancreatitis. Since 01'95 till 12'96 we treated 36 patients with acute pancreatitis. They were diagnosed by US and contrast enhanced CT. 15 patients were intraoperatively classified as necrotizing pancreatitis. US done(More)
UNLABELLED Acute pancreatitis is a severe clinical conditio that causes significant mortality in patients. Since we do not have at the moment effective causal treatment research on the use of pro tease inhibitors can produce tangible benefits. In view of the growing number of cases and high mortality in severe AP with one hand, and the lack of a usal(More)
Ectopic pancreas, a rare entity, is defined as pancreatic tissue lying outside its normal location without anatomical or vascular connections with the pancreas proper. Most occurrences of heterotopic pancreas are located in the stomach wall, duodenum, small intestine or anywhere in the gastrointestinal tract. The aim of this study was to describe the(More)
BACKGROUND/AIMS The aim of the study was to determine to what extent ultrasonography may monitor the process of sphincterotomy and its effectiveness. The study also aimed at determining the sensitivity and specificity of ultrasonography in detecting choledocholithiasis, in comparison with the results of endoscopic retrograde cholangiopancreatography.

Laparoscopic cholecystectomy has become the treatment of choice for gallstone disease. Advantages of the laparoscopic approach include lower morbidity and mortality rates, reduced length of hospital stay, and earlier return to work. In acute cholecystitis, severe inflammation makes laparoscopic dissection technically more demanding, with a higher risk of(More)
It is suggested that vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) play an important role in tumor-induced angiogenesis. The purpose of this study was to estimate the correlation between VEGF and bFGF levels and tumor pathological status according to pTNM classification in patients with squamous cell oesophageal cancer.(More)
