1/147. Simultaneous MALT-type lymphoma and early adenocarcinoma of the stomach associated with helicobacter pylori gastritis.We report about two cases of combined gastric lymphoma and gastric carcinoma with one of them representing a case of early gastric high grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) with co-existing early gastric adenocarcinoma. In contrast to most previously reported similar cases, in both of our cases the definitive diagnosis of gastric lymphoma and carcinoma was obtained preoperatively. This, however, seems to be in future times an essential prerequisite for employing minimal invasive methods such as eradication therapy in the case of diagnosed early lymphoma and endoscopic treatment for early gastric carcinomas. These methods have been proven to be an effective and beneficial alternative treatment especially with regard to the life quality of the patients.- - - - - - - - - - ranking = 1keywords = stomach (Clic here for more details about this article) |
2/147. Phlegmonous inflammation of gastrointestinal tract autopsy study of three cases.Three cases of Phlegmonous inflammation of gastrointestinal tract detected at necropsy are described. Predisposing factors were seen in all three cases. These were chronic alcoholism with submissive hepatic necrosis (HbsAg and HbcAg positive) in Case 1, Indian Childhood cirrhosis in Case 2 and acute on chronic Budd Chiari syndrome in Case 3. In case 1 and 3 the inflammation was limited to the large intestine where as in Case 2 it was seen both in the stomach and large intestine. In two of the three cases blood culture grew staphylococcus aureus (Case 1) and gram negative organisms (Case 2).- - - - - - - - - - ranking = 0.25keywords = stomach (Clic here for more details about this article) |
3/147. Minimal endoscopic aspects of gastric low-grade malt-lymphoma.Low-grade gastric MALT-lymphoma is a neoplasia with a very indolent course and an excellent prognosis. Even if the most common endoscopic findings have described non-specific aspects, often suggestive for benign conditions, the endoscopy reveals a wide range of gastric mucosal changes both at diagnosis and at relapse. We report 2 cases of low-grade gastric MALT-lymphoma in which the diagnosis was made casually because the endoscopic presentation consisted only in mucosal hyperaemia in 1 case and in normal-appearing mucosa of the stomach in the second case. The patients were successfully treated with anti-helicobacter pylori therapy. At 18 and 12 months of follow-up, respectively, the patients were disease-free. The bland appearance of this disease in some patients may reflect the early diagnosis of the tumor. Even if endoscopy and echoendoscopy often constitute useful and reliable diagnostic procedures, in the early phases of the tumor the histologic evaluation of endoscopic biopsies including immunohistochemistry represent the diagnostic procedure more reliably to detect this neoplasm.- - - - - - - - - - ranking = 0.25keywords = stomach (Clic here for more details about this article) |
4/147. Pseudomembranous gastritis: a novel complication of aspergillus infection in a patient with a bone marrow transplant and graft versus host disease.A 36-year-old Hispanic man who had undergone allogeneic bone marrow transplantation, complicated by graft versus host disease, was admitted with acute gastrointestinal symptoms, including severe diarrhea and diffuse abdominal pain. He also had a persistent cough with sputum production. blood cultures yielded escherichia coli, and sputum cultures grew Apergillus species. The patient was treated with antifungal agents and broad-spectrum antibiotics. Despite aggressive medical therapy, the patient died 10 days after admission. Postmortem examination disclosed severe, bilateral confluent bronchopneumonia, with numerous septated branching hyphae consistent with aspergillus species fungal organisms that involved the pulmonary parenchyma and tracheobronchial tree. Although the small and large bowels were only mildly congested, the entire gastric mucosa was covered with a 1.5-cm-thick pseudomembrane that contained numerous aspergillus organisms. Our report represents the first description, to our knowledge, of a diffuse inflammatory pseudomembrane in the stomach, a complication that to date has only been associated with small and large bowel involvement.- - - - - - - - - - ranking = 0.25keywords = stomach (Clic here for more details about this article) |
5/147. Surgical treatment of recalcitrant radiation-induced gastric erosions.BACKGROUND: Uncontrolled bleeding as a result of radiation gastritis in patients who have pharyngo-laryngo-esophagectomy and gastric pull-up is seldom reported. Surgical resection in the management of this condition has rarely been described. METHOD: A 66-year-old man with hypopharyngeal cancer was treated by pharyngo-laryngo-esophagectomy and gastric transposition. He received postoperative radiotherapy and had recurrent hemorrhagic gastritis, necessitating surgical resection. The manubrium was resected to access the mediastinal part of the gastric conduit. The diseased part of the gastric conduit was removed and a free jejunal graft was interposed to replace the resected stomach. RESULTS: Manubrial resection offered adequate access to the stomach transposed in the mediastinum, and the life-threatening bleeding gastritis was successfully controlled by surgical resection. CONCLUSION: Surgical resection of the radiation-damaged transposed stomach through a manubrial resection approach can safely be performed. Free jejunal graft is the choice of reconstruction of the circumferential defect.- - - - - - - - - - ranking = 0.75keywords = stomach (Clic here for more details about this article) |
6/147. Long-term prognosis of idiopathic gastric erosions.The long-term prognosis of multiple gastric erosions (erosive gastritis) is analyzed in 58 cases observed over 10-17 years, showing the disease to recur through decades. Idiopathic erosions occur mainly in the antrum and can be visualized roentgenologically, whereas "stress" erosions are in the body of the stomach and may only be diagnosed endoscopically.- - - - - - - - - - ranking = 0.25keywords = stomach (Clic here for more details about this article) |
7/147. Erosive hemorrhagic gastroduodenitis with fibrinolysis and low factor xiii.Four patients with erosive hemorrhagic gastroduodenitis were found to have high fibrinolytic activity of the gastric juice. No increase in the fibrinolytic activity could be demonstrated in the circulating blood, but the values found for fibrinogen, plasminogen and alpha2-macroglobulin were low. A high content of FDP was found in the serum. All patients had a markedly decreased content of factor xiii. platelet count and other coagulation components were normal. These findings were interpreted as signs of local fibrinolysis in the diseased parts of the gastrointestinal canal. The bleeding stopped after oral and intravenous administration of a fibrinolytic inhibitor (AMCA Cyclokapron) and of factor xiii-containing concentrate. In bleeding from gastroduodenal ulcer and esophageal varices, no increase in gastric fibrinolytic activity was found. It is suggested that the high local fibrinolytic activity in the stomach in erosive gastritis together with the low content of factor xiii contributes substantially to the hemorrhage in this condition. These observations may lead to a revision of the treatment of such cases.- - - - - - - - - - ranking = 0.25keywords = stomach (Clic here for more details about this article) |
8/147. Collagenous gastritis: a case report, morphologic evaluation, and review.Collagenous gastritis is rare; there are only four previous case reports. Histologic features seem to overlap with the other "collagenous enterocolitides"; however, pathologic criteria are not yet established for the diagnosis of collagenous gastritis. We describe an additional case of ostensible collagenous gastritis in a patient who initially presented with celiac sprue and subsequently developed colonic manifestations of mucosal ulcerative colitis. Endoscopic biopsies of the stomach revealed deposition of patchy, very thick bandlike subepithelial collagen in gastric antral mucosa, focal superficial epithelial degeneration, numerous intraepithelial lymphocytes, and a dense lamina propria lymphoplasmacytic infiltrate. Image analysis evaluation of gastric antral biopsies demonstrated a mean thickness of subepithelial collagen of 27.07 micron. Morphologic comparison was made with age-matched control groups of 10 patients who had normal gastric mucosal biopsies and 10 patients who had "chronic" gastritis, which revealed mean subepithelial collagen measures of 1.37 micron and 1.19 micron, respectively. We compared these morphologic findings with those of all previous case reports of collagenous gastritis and propose a pathologic definition based on the limited combined data. It seems that subepithelial collagen is dramatically thickened in reported cases of collagenous gastritis, with a cumulative mean measure of 36.9 micron. It is also apparent from this and previous reports that the thickened subepithelial collagen is accompanied by a chronic or chronic active gastritis and sometimes intraepithelial lymphocytes and surface epithelial damage. Recently described associations of lymphocytic gastritis, sprue, and lymphocytic colitis as well as collagenous and lymphocytic colitis suggest a common pathogenesis that empirically may include collagenous gastritis in the same disease spectrum. We propose that collagenous gastritis can be confidently identified by using analogous defined features of collagenous colitis: subepithelial collagen more than 10 micron in a patchy distribution, lamina propria lymphoplasmacytic infiltrates, intraepithelial lymphocytes, and surface epithelial damage. Collagenous gastritis also seems to have the same spectrum of associated clinical findings as collagenous colitis, including frequent coexistence of celiac sprue, watery diarrhea syndrome, and female predominance.- - - - - - - - - - ranking = 0.25keywords = stomach (Clic here for more details about this article) |
9/147. Direct evidence by dna fingerprinting that endoscopic cross-infection of helicobacter pylori is a cause of postendoscopic acute gastritis.The dna fingerprinting of helicobacter pylori strains in two cases of acute gastritis that occurred after endoscopy was examined. H. pylori was isolated from the stomachs of two patients with acute gastritis and from the stomachs of the patients in whom the same gastrofiberscope had previously been used. The genomic DNA digested with HaeIII was subjected to pulsed-field gel electrophoresis. The corresponding paired electrophoretic patterns were completely identical. These findings provide direct evidence that postendoscopic acute gastritis can be caused by cross-infection with H. pylori via endoscopy.- - - - - - - - - - ranking = 0.5keywords = stomach (Clic here for more details about this article) |
10/147. Endoscopic observation of squamous metaplasia of the stomach: a report of two cases.Squamous metaplasia of the stomach is a rare clinical entity that occurs during healing of gastric ulcers or chronic inflammation. We have treated two patients with this condition, which has only occasionally been observed endoscopically. The first was a 60-year-old woman who initially presented with multiple gastric ulcers. Two months after treatment, a white patch about 4 cm in diameter was found in the lesser curvature of the cardiac region of stomach. The second patient was a 65-year-old woman, who also developed a white patch in the same region. Two months later, a small ulcer and inflamed mucosa were seen near the lesion. The white areas in both patients were stained with Lugol's iodine solution, and biopsy specimens confirmed squamous epithelium. The squamous metaplasia was observed as a white mucosal area in the stomach, and the metaplastic area stained positively with Lugol's iodine solution.- - - - - - - - - - ranking = 1.75keywords = stomach (Clic here for more details about this article) |
