The pathologic features and five-year survival of patients in whom gastric cancer masquerades at endoscopy as a benign gastric ulcer has been poorly characterized. We reviewed retrospectively all cases of gastric adenocarcinoma in three hospitals for a five-year period. Of 266 patients with gastric adenocarcinoma, 169 (63.5%) had endoscopy with biopsy prior to diagnosis of cancer. In 159 of these 169 patients (94.1%), the endoscopic findings suggested cancer, while in the remaining 10 patients (5.9%) the endoscopic appearance suggested benign ulcer. In six of these 10 patients, the initial endoscopic biopsies did not reveal cancer and correct diagnosis was delayed for as long as 14 months. Three of the 10 patients had "early gastric cancer" by pathologic criteria at gastrectomy, although one had lymph node metastasis. The other seven patients had pathologic criteria for advanced gastric cancer, and three had lymph node metastasis. In spite of advanced cancer and/or lymph node metastasis in eight of our 10 patients, five-year survival in these patients with benign-appearing ulcers was 70%, as compared to 17% in patients whose gastric lesions appeared malignant at endoscopy.

We developed a simple method of determining gastric juice viscosity using a cone plate viscometer and tested its clinical application in the staging of peptic ulcers. We found a significant positive correlation between viscosity and macromolecular glycoprotein concentration of gastric juice (P less than 0.001). Gastric juice viscosity in active and healing gastric ulcer patients was significantly lower than that in the scarring stage or hospital control patients (P less than 0.05 and P less than 0.01, respectively). In duodenal ulcer patients, a significant difference was found between the active and healing stages and hospital controls (P less than 0.01). However, the difference between the active and healing stages and the scarring stage was not significant. Gastric juice viscosity is a simple, reliable, clinically useful measure.

The expression of the carbohydrate antigen CA 19-9 in human gastric mucosa was studied by using the monoclonal 1116 NS 19-9 antibody, immunohistochemical ABC staining technique and formalin-fixed, paraffin-embedded biopsy specimens. Among 26 gastric carcinoma (GCA) patients CA 19-9 antigen was found in 16 patients (62%). The antigen was also found in 10 (48%) out of 21 non-cancer patients who had benign gastric ulcer and in 9 (12%) out of 74 non-ulcer, non-cancer patients. In non-cancerous mucosa, the CA 19-9 antigen was localized in the surface epithelium (foveolar type of staining) and/or in goblet cells and sometimes in absorptive epithelium of metaplastic intestinal glands (goblet cell type). The foveolar type but not the goblet cell type was related to the nonsecretor status of the subject, to Le positivity and to anti-H negativity of the gastric surface epithelium. It is concluded that, although being commonly present in GCA tissue, the expression of the antigen in benign gastric tissue is too common to advocate the practical value of CA 19-9 in predicting malignant gastric lesions in immunohistochemistry.

Forty cases of upper gastrointestinal bleeding were studied. Twenty-three patients had shock and active bleeding (3 spurting, 12 oozing and 2 a clot with oozing) or stigmata of recent hemorrhage (4 with a clot and 2 with a visible vessel). Nineteen of these were submitted to endoscopic injection. In 4 cases with multiple acute hemorrhagic lesions and shock, and in 17 patients with stigmata of recent bleeding without shock, the technique was not carried out. None of the patients had a rebleed. One patient was submitted to surgery 24 hours after injection for a large acute gastric ulcer in the process of perforating, and died of pulmonary embolism 4 days later. No technique-related complications were observed. We believe endoscopic injection treatment might be the technique of choice in patients with shock and active bleeding or stigmata of recent hemorrhage of the upper gastrointestinal tract.

The aim of this study was to determine if a defect in ventilatory function is present in patients with chronic peptic ulcer and if so, is it present in both gastric and duodenal ulcer and is it related to smoking. Fifty-six patients with peptic ulceration (27 gastric ulcer, 29 duodenal ulcer), together with 56 healthy controls matched for age, sex, and smoking status, were studied. Ventilatory function was measured and the ABH blood group antigen secretor status was determined. Vital capacity and forced expiratory volume in 1 s were significantly reduced in both smokers and nonsmokers with gastric ulcer when compared with controls; total lung capacity was lower than controls only in smokers with gastric ulcer. In duodenal ulcer patients, a trend similar to that observed in gastric ulcer patients was present. It is concluded that a defect in ventilatory function is present in patients with chronic gastric ulcer; a lesser defect is present in patients with duodenal ulcer.

In a single-centre study 59 patients with gastric ulcer were treated either with 300 mg ranitidine at night or with 150 mg ranitidine twice daily. After 4 and 8 weeks 73% and 97%, respectively, of those treated with 300 mg at night and 59% and 86% of those treated with 150 mg twice daily had complete ulcer healing. These differences between the two groups were not statistically significant. No serious side effects were seen. Ranitidine, 300 mg at night, appears to be at least as effective as the standard 150 mg twice daily regimen in the treatment of gastric ulcer.

In a prospective study of 120 gastroenterological patients in Berlin, Germany, the prevalence of Campylobacter pylori was determined. When the gastric mucosa was normal, the prevalence was one in 19 patients (5.3%). In 101 patients with chronic gastritis it was cultured in 55 (54.5%). In 31 patients with chronic atrophic gastritis the organism was cultured in 25 (81%); in 60 patients with severe gastritis it was present in 75%, in 35 with moderate or severe chronic active gastritis in 82.8%. The diagnosis of gastric ulcer (9) or duodenal ulcer (12) was associated with the isolation of Campylobacter pylori in 55.6 and 91.7%, respectively. The prevalence of this organism in antral mucosa of this group of patients thus corresponds to that in Australia, England and North America. The organism was also demonstrated in the duodenum of 10 among 25 patients examined. But in none of 25 patients was it demonstrated in the sigmoid colon.

Gastric ulcerations induced in rats by a combination of indomethacin and cold-stress (5 +/- 1 degrees C) for 6 hr were more severe than those induced by indomethacin or cold-stress alone. The acidity of gastric juice was increased in rats treated with indomethacin plus cold-stressed. Histamine H2 receptor antagonists, (H+-K+) ATPase inhibitors and prostaglandins inhibited gastric ulcer formation in indomethacin plus cold-stress treated rats, whereas anticholinergics aggravated the ulceration. The indomethacin plus cold-stress induced acid secretion was inhibited by cimetidine and omeprazole in pylorus-ligated rats. Atropine had less effect on the increase in acidity than cimetidine and omeprazole. These findings indicate that the ulcer formation in indomethacin plus cold-stress treated rats is related the increased in acidity of gastric juice. This gastric ulcer model may be useful for evaluating antiulcer agents.

Colloidal bismuth subcitrate (CBS) precipitates in an acid environment, adheres to mucus, blocks pepsin activity, retards hydrogen-ion back diffusion and stimulates prostaglandin synthesis. The average healing rate after 4 weeks' treatment with CBS is 78% in duodenal ulcer versus 67% with cimetidine. A direct comparison with ranitidine gives healing rates of 78% (CBS) as opposed to 78% with ranitidine. The corresponding figures in gastric ulcer are 68% (CBS) and 54% (cimetidine). The percentage of relapse-free patients is substantially higher after CBS ulcer healing than after H2-blockers. Bismuth subsalicylate eliminates Campylobacter pylori in 71% after 4-weeks' therapy. Parallel to this elimination a decrease and normalization of the acute inflammatory process can be seen in antral mucosa.

6-[1S-(3S,4-Dihydro-8- hydroxy-1H-2-benzo-pyran-1-one-3-yl)- methylbutylamino]-4S,5S-dihydroxy-6-oxo-3S-ammoniohexanoate (AI-77B)-gamma-lactone-N-ethyl derivative (AI-77-C2) is a new antiinflammatory drug with antiulcer activity. In the first part of the present study the ulcerogenicity of this drug was assessed. Acidic antiinflammatory drugs--indomethacin and diclofenac--and basic antiinflammatory drugs--tiaramide and mepirizole--were used for comparison. Although AI-77-C2 was barely ulcerogenic at 7 h after dosing, some lesions developed in both stomach and intestine at 24 h. Repeated administrations over 5 days appeared to increase its ulcerogenicity and general toxicity. Marked gastric ulcers were induced by indomethacin and diclofenac, and severe intestinal ulcers were also produced at 24 h and by their repeated administration. Tiaramide did not induce marked ulcers in any case. Although the ulcerogenicity of mepirizole was weak at 7 h, severe duodenal ulcers developed at 24 h and after the repeated administration. From the results given above, it was concluded that the ulcerogenicity of AI-77-C2 was relatively low. In the next study, the antiulcer activity of AI-77-C2 was examined in several experimental ulcer models. AI-77-C2 showed a marked inhibition of all the models presently employed, i.e., the indomethacin-induced gastric ulcer, the pylorus ligation ulcer, the water immersion stress ulcer, and the acetylsalicylic acid-induced ulcer in rats. It was observed that AI-77-C2 suppressed the gastric secretion and movement. It is therefore concluded that the antiinflammatory drug AI-77-C2 has low ulcerogenicity and potent antiulcer activity.(ABSTRACT TRUNCATED AT 250 WORDS)
