Evolutive and prognostic aspects in gastric cancer. Analysis of 189 cases.

The cases of 189 patients treated at the Surgery Service for gastric carcinoma from January 1960 to December 1978 and followed until April 1984 were reviewed in terms of evolutive behavior. Correlations between sex, age, duration of symptoms, site of tumors, lymph node metastases, stage of tumors, operability, resectability, treatment and survival were attempted. With respect to age, of the patients not operated on, survival was longer for more advanced age; the opposite occurred for the group of patients who were operated on. The impairment of lymph nodes was decisive in shortening survival; men were affected more than women and had a worse prognosis. When the tumors were located in the proximal third of the stomach, the survival rate was longer than when they were located in the distal portion and middle third of the stomach. Patients who had experienced digestive symptoms for a long time survived longer than those with a short history. It was concluded that the main prognostic factor was resectability and, regardless of any other variables, only patients from the group submitted to gastric resection survived more than 5 years.

Evaluation of vagotomy by the Hollander-Congo red test.

In the present study, the completeness of vagotomy in patients who underwent truncal and highly selective vagotomy is evaluated, comparing them with control groups of normal persons and patients with a duodenal ulcer. The evaluation was made by the Hollander test, followed by the endoscopic Congo red test, using the same hypoglycemic stimulus. Gastric acid production was higher in the patients with duodenal ulcer, followed by the normal persons. Lower acidity levels were obtained for patients with truncal vagotomy than for patients with highly selective vagotomy. During the Congo red test, we noted that the patients with truncal or highly selective vagotomy had small black spots in the gastric mucosa, except those having a recurrent ulcer, denoting incomplete vagotomy. Nevertheless, when we observed the appearance of the gastric mucosa, we noted a similar aspect for those having had a vagotomy and for normal persons. This appearance was completely different from the patients with a duodenal ulcer. We concluded that truncal vagotomy greatly reduces the level of gastric acid production, while highly selective vagotomy does so to a lesser extent. The endoscopic aspect of these patients during the Congo red test was similar to that for normal persons.

[Normal value of electrolytes in the gastric juice].

In the present paper, the authors present the concentrations of electrolytes (Na, K, Ca, Mg and Cl) in the gastric juice of Na and K obtained by the flame photometer and by the atomic absorption spectrophotometer and conclude that the flame photometer may give false results when used to determine the electrolytes in the gastric juice.

[Thickness of the pyloric muscle in relation to Chagas' disease].

The authors analyzed the thickness of the pyloric muscle of 139 patients with peptic ulcer or gastric cancer. Subtracting the muscular thickness of pylorus measured by a ruler from the thickness estimated by the formula, P.T.=0.0415 X W+2.9, where P.T. represents the thickness of the pyloric muscle in millimeters and W represents the weight of the body in kilograms, they had the deviation from normal, in mm. The muscles with deviations greater than 3 mm were considered hypertrophics. Comparing their material with those of Horwitz et al the authors observed a difference in the group of patients with duodenal ulcer without stenosis in which they obtained 16.5% cases with muscular hypertrophy. Surprisingly, those patients showed positivity of sorologic reactions to Chagas' disease in 83.3% of the cases. These results together with the work of Kunze which demonstrated in 1973 that Chagas' disease may be one of the causative factors of the pyloric muscular hypertrophy, make the authors attribute to the neurological disturbances caused by the American Tripanosomiasis the difference observed.

[Infusion of ileal juice by distal stoma].

The authors present a simple and practical method to avoid the ileal juice expoliation in patients with ileostomy after intestinal resection. In the cases presented, after the resection, stomies were performed of the proximal and distal portions of the intestine, in relation to the extirpated segment. The juice collected in the proximal stomy was infused in the distal stomy, simulating that way the physiologic intestinal transit.

[Study of the length of a stay of partial gastroduodenectomized patients].

The length of stay for 482 partial gastrectomy patients in the Servico de Cirurgia de Ribeirao Preto in the period from 1960 to 1974 is compared with that of four other neighbor hospitals for the year 1973. There was reduction in the length of stay during these years and it was more obvious when compared the other four hospitals. The authors claim that early discharge and home management should always be recommended and suggest an analysis of factors interfering with length of stay.

[Arterio-mesenteric occlusion of the duodenum in Chagas' disease].

The authors present eight cases of arterio-mesenteric duodenal ileus diagnosed in the Serviço de Cirurgia de Ribeirão Preto (São Paula--Brasil) among 2.573 surgical interventions of digestive tract performed in 15 years. Seven (87.5%) cases presented positive complement fixation test for Chagas' disease and signs of Chagas' cardiopathy and/or enteropathy. Comparing similar casuist studies published in Brazil, the authors suggest that American Trypanosomiasis must be considered as a contributive factor in the genesis of arterio-mesenteric duodenal ileus in Latin America.
