[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] Gastric wall abscess, a localized form of bacterial infection, is rare condition. Authors reported a case of gastric wall abscess caused by Klebsiella pneumoniae, presenting submucosal mass on upper gastrointestinal series. Clinical, pathological and radiological findings are discussed.
[en] Primary gastric lymphomas are the most common extra nodal lymphomas. They can be presented as aggressive or indolent, majority of indolent lymphomas are associated to H. pylori infection. The basic diagnostic procedures are endoscopy, endo sonography and biopsy of gastric tissue. Therapy is related to the histological subtype, stage, H. pylori positivity, clinical symptoms and condition of patient. The aim of the treatment is remission as well as good quality of life. The prognosis of patients with primary gastric lymphomas is relatively good. (author)
