The aim of the present study was to assess the possible correlation of p53 with CEA and Ca 19-9 serum levels as well as with selected clinicopathological data. 46 patients, who were gastrectomized due to gastric cancer between 1998 and 2001, were analyzed. The concentration of CEA and Ca 19.9 was estimated in serum. Mean percentage of p53-positive cells in present group was 33,69 %. The comparison of mean percentage of p53-positive cells with IHC reaction intensity revealed statistically significant, directly proportional correlation, with p<0,001. Mean CEA and Ca 19-9 serum concentration were 1,75± 1,71 ng/ml, and 17,34±44,73 U/ml respectively. No significant correlation between p53-expression, CEA and Cal9-9 was noted respecting several clinicopathological data of tumors. However clear trend of higher CEA and Cal9-9 values in groups of potentially worse prognosis (T3-T4; Nl-2; III grade of disease) was observed.
Diverticula of the upper part of the alimentary tract, irrespective of their etiology, are frequently observed benign changes of the pharynx, oesophagus, stomach and duodenum. In the present work, patients of the II General Surgery Department of the Medical University of Lublin, with radiologically or endoscopically proved diverticula of the upper part of the alimentary tract, were examined. The presence of diverticula of such localisation was an indication for supplementary endoscopic or radiological examination. The localisation, size, diameter of the opening, mucosal relief of diverticula and its contiguity were checked and analysed. Our data suggest that both medical procedures are complementary to each other. All previously observed changes in diverticula of the thoracic part of the oesophagus and the infradiaphragm part of the alimentary tract were fully proved. The radiological examination gave a better view of Zenker’s diverticulum, especially in short and obese patients. Sampling and better visualisation of the diverticula opening testify to the unquestionable superiority of endoscopy. However, precise evaluation by radiological process fully completes the diagnostic protocol. Both diagnostic procedures are usually supplemented by manometric examination of the oesophagus and superior and inferior oesophageal sphincters. This enables the accurate diverticula etiology to be stated.
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 endoscopic, endosonographic (EUS) and radiological features of these lesions. Management of the ectopic pancreas remains controversial. The authors describe 12 patients and try to recommend different kind of treatment in the light of the symptoms, location and size of the lesions.
