[en] The term stromal tumor was coined in 1983 by Clark and Mazur for smooth muscle neoplasm of the gastrointestinal tract (GIT). Gastrointestinal stromal tumors (GIST) are nonepithelial tumors arising from the interstitial cells of Cajal, which express KIT protein-CD117 on immunohistochemistry. GIST can arise anywhere in the GIT, including the mesentery, omentum, and retroperitoneum
[en] Nuclear scintigraphy for the detection of gastrointestinal bleeding (mostly lower GI bleeding) includes several techniques which are rapid, easily performed, of minimal risk and relatively low radiation exposure to the patient and have a high sensitivity. These examinations are excellent as initial procedures for the localization of gastrointestinal bleeding. (author). 28 refs.; 9 figs
[en] The third volume of the Gastroenterology Annual covers the period July 1982 - December 1984 and provides a scholarly, up-to-date, critical review of important new developments in the field. The book includes a chapter on radiography and NMR imaging. (G.J.P.)
[en] Gastric carcinoma is the most common malignancy of the stomach and for many reasons it is one of the most interesting gastroenterology topics. From the epidemiology standpoint, it is because of its high incidence in Eastern Asia, as well as some parts of South America. As far as the cause, the gastric carcinoma is interesting for its connection with Helicobacter Pylori and the debate of potential screening. The diagnostics of this disease opens up the question of „early gastric carcinoma“ and the expansion of possibilities of endoscopic treatment, especially by Japanese and Korean authors. A less positive aspect is the potential palliative influence of advanced diagnoses. (author)
[en] Ectopic pancreas is a rare congenital anomaly. It is usually asymptomatic, or presents with non specific gastrointestinal symptoms. We describe here a case of ectopic pancreas in the gastric antrum, with pseudocyst and pseudoaneurysm formation. This entity has not been reported previously in the literature.
[en] The most serious problem in surgical treatment of gastric cancer include extent of resection and extent of lymphadenectomy. Extent of gastric resection determines the extent of tumor affection. The aim of radical surgical intervention is to achieve microscopically clear resection line since R0 resection is the main criterium for the prognosis of the patient. Curative surgical resection for gastric cancer is including lymph node dissection. In the treatment of gastric cancer are two views on the importance of lymphadenectomy. The Far East is considered a performance with therapeutic potential, in Europe is considered for the performance of designated staging and prognosis, but its implementation will not affect the prognosis, it is also a difference in the staging system. East based on the anatomical location of metastatic lymph nodes, in Europe the number of positive lymph nodes. (author)
[en] A benign anastomotic stricture is a common complication of upper gastrointestinal (UGI) surgery and is difficult to manage conservatively. Fluoroscopically guided balloon dilation has a number of advantages and is a safe and effective procedure for the treatment of various benign anastomotic strictures in the UGI tract
[en] Radiologic diagnosis of colorectal foreign bodies is usually not very difficult, because inserted materials are often clearly visible on plain abdominal radiographs. However, when they are radiolucent, a plain abdominal radiograph has been reported to be useless. As radiolucent colorectal foreign bodies appear as radiolucent artificial contours or air-trapped materials in the pelvis, almost always the diagnosis itself can be made by careful evaluation of plain abdominal radiographs. We encountered a case of casting type of radiolucent colorectal foreign body formed from polyurethane foam. It presented US with unexpected radiologic findings and led to diagnostic difficulties
[en] The author studied, with emphasis on the various radiographic projections, the 99 cases of liver enlargement, which underwent the barium meal upper gastrointestinal examinations for the purpose of pursuit of significance of liver enlargement and, at the same time were confirmed by other clinical and pathological methods at Busan National University Hospital for about 2 years from November 1977 to September 1979. The following results were obtained: 1. The incidence of liver enlargement was 63.3% (62 cases) in the 5th decade, which was most prevalent, 18.2% (18 cases) in the 3rd decade, 15.2% (15 cases) in the group over 60, and 3.0% (3 cases) in the age group below 20. Male to female sex ratio was 2 : 1. 2. The causes of the liver enlargement confirmed by the final diagnosis are as follows: Primary hepatic cancer 39 cases (39.3%), liver cirrhosis 30 cases (30.3%), chronic hepatitis 12 cases (12.1%), cancer of the biliary tract 6 cases (6.1%), hepatic fluke 6 cases (6.1%), metastatic tumors 3 cases (3.0%), and hepatic congestion 3 cases (3.0%) 3. In the prone view, the displacement of the duodenal bulb appeared in 18 cases (18.2%). 4. In the routine radiographs, the displacement of the stomach to the left and the pressure indentation of the lesser curvature were noted in 69 cases (69.7%) out of 99 cases. 5.In the left lateral recumbent view, the pressure indentation of the anterior border of the gastric body was seen in 96 cases (97.0%) among the 99 cases, the straightening in 30 cases (27.3%), the marked depression in 30 cases (30.3%), the moderate in 27 cases (27.3%), the minimal in 9 cases (9.1%). 6. Comparing the incidences of the roentgen findings of the liver enlargement in the various projections respectively, the displacement of the duodenal bulb was noted in 18 cases (18.3%) in the prone position. The erect position revealed the displacement of the stomach to the left and the pressure indentation in 57 cases (57.6%), the prone position in 51 cases (51.5%), and the supine view in 36 cases (36.4%). The left lateral recumbent view, however, demonstrated the good result of 96 cases (97.0%). 7. The cases of the liver enlargement unable to be detected by physical examination could be found in 39 cases (39.4%) in the left lateral recumbent projections. 8. Even in some cases of hepatic cancer invading the right lobe of the liver and those showing no significant findings in the routine views, the left lateral recumbent view demonstrated the pressure indentation. 9. The left lateral recumbent view showed the more prominent pressure indentation then the left lateral erect projection. 10. Consequently, the authors concluded that the left lateral recumbent was the best position to reveal the liver enlargement and had the high accuracy.
