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)
BACKGROUND 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(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)
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)
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)
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)
The differential diagnosis of the focal lesions in the region of the pancreas is difficult due to the similarity of clinical and radiological pictures of neoplastic and non-neoplastic lesions. This paper presents the most common causes of errors in ultrasound diagnosis of pancreatic pathologies. Attention was paid to the errors resulting from the structural(More)
Ultrasound examination of the pancreas constitutes an integral part of the abdominal ultrasound. It is mostly indicated to diagnose pain in the epigastrium, discomfort and jaundice as well as to monitor the patients with acute pancreatitis. The assessment of this organ in an ultrasound examination may be problematic due to its anatomical location and the(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)
UNLABELLED Intraoperative ultrasound (IOUS) allows confirming and verifying the preoperative diagnosis. In many cases it allows correct determination of the severity of the disease, safe surgery performance and shortening its duration. Proper assessment of anatomic structures during the surgery and evaluation of the operating field after the treatment(More)
