A method for measurement of gastrin in gastric mucosa has been developed, and distribution of gastrin in the stomach of pig, dog, cat, rabbit, and man was examined. Measurable amounts of gastrin were found in corpus of all species, but the content in the antrum was considerably higher. The highest concentration of gastrin was seen in man. The borderline between corpus and antrum was abrupt, and in both parts of the stomach gastrin was evenly distributed. In 44 patients with duodenal ulcer the antral gastrin concentration was 21.3 mug eqv. per g mucosa, in 15 patients with prepyloric ulcer 23.0, in 10 patients with gastric ulcer 5.9, and in 16 patients with gastric carcinoma 7.9. The control group consisted of 10 healthy volunteers and 12 patients with minor abdominal complaints. Mean antral gastrin concentrations were 28.1 and 20.7 respectively. No significant relationship was observed between PAO and gastrin content of antral mucosa in any group.

This is the report of the presence of a benign gastric ulcer in a patient with achlorhydria and documented pernicious anemia. The pernicious anemia was established by a Histalog-fast achlorhydria, a Schilling test of 2.1% excretion of tagges vitamin B12 in a 24-hr urine, and reticulocytosis after administration of cyanocobalamine. Following Histalog (1.5 mg per kg of body weight), the gastric volume was 40 ml, there was no acid, and the pH was 8.1. The ulcer demonstrated by gastroscopy was confirmed at gastrectomy. Histological examination of the ulcer and the remainder of the stomach showed no malignancy. The principal conclusion of this paper is that the patient did not have an acid-produced ulcer, but that bile regurgitation coupled with alcohol ingestion produced the lesion. Surgical investigation of the ulcer seemed mandatory because of the known increased incidence of gastric carcinoma in patients with pernicious anemia.

This paper considers the further surgical management of patients who have had a gastric ulcer removed which was apparently benign but which on subsequent histological examination has proved to be a carcinoma. A retrospective review of 59 such patients has been undertaken. A non-radical partial gastrectomy was performed in the first instance on all these patients; 24 of them had a second operation once the correct diagnosis had been reached and 35 had no further surgery. These two groups are compared. The overall 5-year survival in the non-revisional group was only 23% compared with 56% in those treated by a second operation. It is thought that revisional surgery should be undertaken within 6-8 weeks, provided the age and general condition of the patient are satisfactory. Since 1970 the routine use of fibreoptic endoscopy and biopsy has virtually eliminated the problem.

The microflora of the stomach is derived from both the ingestion of food and saliva and the reflux of proximal intestinal contents through the pylorus. Normally, this microflora is inhibited by gastric acid and normal gastric motility. In disease states, however, such as bleeding or obstructing duodenal ulcer, gastric ulcer or carcinoma, the level of gastric acid is reduced or the gastric motility is altered. Thus, endogenous microflora persists and often becomes the source of postoperative wound infections following gastric resection.

About 5--10% of the gastric carcinomas develop from a gastric ulcer (ulcerocancer). This process, however, is, referred to gastric ulcers, too rare to indicate a prophylactic resection of the stomach on account of the danger of the development of cancer. Careful diagnostics and following control with X-ray examination and gastroscopy are, however, necessary in every gastric ulcer. The retrogression of the complaints neither proves healing of the ulcer nor benignity of the ulcer. Compared with the ulcerocarcinoma the differential diagnosis of the gastric ulcer is easy when locally advanced, patelliform carcinomas are in question. It is difficult in small carcinomas and especially in the carcinoma of the mucous membrane of type III. Individual radiologic and endoscopic signs and especially their combination are useful for the differentiation, but they may be misleading. A carcinomatous ulcer may radiologically and endoscopically look like a peptic ulcer and may apparently also fully heal. Therefore, a certain differential diagnosis is only possible with the help of an aimed biopsy of the stomach or the cytodiagnostics. The two methods serve further propagation. They should be used in every case, when an apparantly benign ulcer does not reveal a clear retrogression under effective treatment with carbenoxolone within four weeks. The examination of the gastric juice may be used for the differential diagnosis.

During the recent 13 years from 1961 to 1973, 21 cases of ulcer-carcinoma satisfying Hauser's pathologic criteria have been found endoscopically, 5 cases (2.6%) of which were mucosal carcinoma accompanying linear ulcer over 30 min in length. In addition, one submucosal carcinoma and 2 cases of sub-early gastric carcinoma, partially invaded into the proper muscle layer, were used for this study. Using these 8 cases and 11 operated ones of benign linear ulcer, we have a comprehensive study of histologic and clinical findings of both groups. As the results, malignant linear ulcer was similar in condition to the benign, either in mother ground or in histologic and clinical findings. Moreover, coexistent carcinoma with all kinds of gastric ulcer and with linear ulcer among them was found in 1.5% and 3.8%, respectively. In a series of controlled group, early gastric carcinoma was found in 2.1% out of 284 cases of no ulcer scar from its follow-up study. Its x2 test revealed no significant difference among these values. However, we might conclude that endoscopical follow-up study of chronic gastric ulcer, especially long linear ulcer, is indispensable for understanding the evaluation of malignant change of ch ronic gastric ulcer.

The gastric ulcer and carcinoma in the fundic gland area were investigated with the surgically resected cases. 1. The frequency of the ulcer in the fundic gland area was 8.2% of 2194 cases of gastric ulcer and that of carcinoma in this area was 8.4% of 780 cases of gastric carcinoma. These two diseases showed high frequency in the age group of forty to fifty years withpreponderance in female. 2. The ulcers in the fundic gland area usually showed high acidity and high frequency of massive bleeding like as melena and hematemesis comparing with other lesions or the ulcers in other sites. 3. The ratio of the low-differentiated carcinomas to the well-differentiated ones was about 3.7 to 1 in the fundic gland area and 1 to 1.3 in the pyrolic gland area. 4. The frequency of the early gastric carcinomas was 27% and 41% in the fundic and pyrolic gland areas, respectively. 5. In the fundic gland area, as observed in the pyrolic gland area, the low-differentiated carcinomas usually occurred on the non-metaplastic mucosa and the majority of well-differentiated ones were frequently found in association with the intestinal metaplasia. 6. Although the solitary carcinoma in the anterior wall or greater curvature was found not infrequently, the solitary ulcer was not found in these sites in this series.

The results of selective proximal vagotomy and pyloroplasty for duodenal and gastric ulcer in 464 patients over the last 5 years were evaluated in 438 cases. More than 75% of the patients were observed for 2 years after the operation. More than 25% were emergency cases, the incidence of intraoperative complications like splenic lesions or perforation of the esophagus was 3.2%. Postoperative complications like leakage of the pyloroplasty, peritonitis, hemorrhage from the pyloroplasty or disruption of the laparotomy closure occurred in 14,4%. The overall mortality was 4.6%, the elective mortality 1.6%. Recurrent ulcers were seen after 1/2-2 1/4 years with an overall rate of 3.2%. Over half of these cases required relaparotomy. In 5.3% relaparotomy had to be done for peritonitis, GI-bleeding, bleeding from the lesser curvature of the stomach, ileus or carcinoma. The Pentagastrin stimulated gastric secretion remained constantly reduced for more then 2 years in over 60%. Following the Visick-grading system the results were good in 61-65% of the patients and bad in 16-22% depending on the time of observation.

A controlled prospective study was undertaken to determine if fluids which bathe malignancies may contain carcinoembryonic antigen (CEA) earlier in the course of gastrointestinal cancer than does plasma of the same patient and may offer a better means for diagnosis. CEA titers were normal (less than 2.5 ng per ml) in the plasma of 42 healthy volunteers. Normal CEA levels were also found in the plasma and in the colonic mucus of 14, the gastric juice of 18, duodenal drainage of 10, and bile of 11 normal control subjects. The colonic mucus of 3 patients with ulcerative colitis, gastric secretions of 5 benign gastric ulcer patients, bile specimens from 11 normal control subjects and from 5 gallstone patients contained CEA at concentrations below 2.5 ng per ml. Positive CEA titers were found in the fluids bathing tumors of all 23 patients with colonic carcinoma, 9 of 17 patients with gastric carcinoma, and all 6 patients with pancreatic carcinoma. In contrast, positive CEA titers were found in the plasma of only 16 of 23 patients with colon carcinoma, 6 of 17 patients with gastric carcinoma, and 4 of 6 patients with pancreatic carcinoma. Among 46 patients with gastrointestinal malignancies, CEA was detected in significant concentrations in the plasma of 26 patients and in fluids bathing tumors of 38 patients. These results indicate a significant association of adenocarcinoma of the colon with CEA-positive colonic mucus (P less than 0.01) and suggest the usefulness of assaying CEA in fluids bathing tumors for the detection of gastrointestinal malignancies.

To determine the prevalence and significance of Helicobacter pylori (H. pylori) infection, biopsies of the antral mucosa were obtained from 139 patients and 43 asymptomatic volunteers. The specimens were examined by hematoxylin-eosin staining and the ureas test. The detection rate of H. pylori by histologic examination was 91.3% in patients with duodenal ulcer, 75.0% in those with combined duodenal and gastric ulcer, 63.6% in those with gastric ulcer, 22.9% in those with gastric carcinoma, 36.4% in those with gastric adenoma, 14.3% in those with gastric hyperplastic polyp, and 51.7% in those with gastritis, and the respective percentages detected by the urease test were 91.3%, 75.0%, 54.5%, 28.6%, 27.3%, 14.3%, and 44.8%. H. pylori was also detected in 10/43 (23.3%) asymptomatic healthy volunteers by histology and the urease test. The prevalence of H. pylori was significantly higher in the patients than in the asymptomatic healthy volunteers (p < 0.05). H. pylori was detected in 62.9% of patients with endoscopic erosive gastritis and in 97.9% of those with histologically proven chronic active gastritis. The urease test was positive in 77/82 patients who were histologically positive for the organism (sensitivity: 93.9%), and it was negative in 98/100 patients who were negative by histology (specificity: 98.0%). Thus, there was over 90% agreement between the urease test and histology. Our investigations showed that H. pylori was closely related to peptic ulcers and antral gastritis, and that the urease test provides a simple, rapid and accurate diagnosis of H. pylori infection.
