Helicobacter pylori after surgery for duodenal ulcer.

Background/aims: The role of Helicobacter pylori as a cause of peptic ulcer is still subject to controversy. The Kock's postulates have not been yet fulfilled; the bacteria can be found in normal persons, and it persists in the stomach after the ulcer is healed.

Material And Methods: The authors analyzed 41 persons formerly submitted to surgery (after 8 years and 4 months, as a mean), 31 to highly selective vagotomy, and 10 to truncal or selective vagotomy plus gastroduodenal drainage.

[Acute appendicitis in pregnancy].

A retrospective analysis of acute appendicitis during pregnancy in patients seen at the Surgical Service of Ribeirão Preto between December 1959 and December 1988 showed that out of 18,065 deliveries performed there were 7 cases of acute appendicitis (0.038%). Gestational age in which acute appendicitis developed varied from the 11th to the 27th week, the second trimester prevailing.

Nonocclusive intestinal ischemia and necrosis after correction of interatrial communication with cardiopulmonary bypass. A rare and catastrophic complication.

The authors present a case of massive, nonocclusive intestinal ischemia and necrosis after surgery for correction of interatrial communication with cardiopulmonary bypass in a 22-year-old woman. This is an extremely serious complication that generally occurs in older patients. The literature mentions its occurrence in patients subjected to aortic valve replacement who have low cardiac output and in patients undergoing myocardial revascularization.

[Hospital infection at a private hospital in Ribeirão Preto, São Paulo, Brazil].

The aim of this work is to prospectively evaluate the incidence of infection, from June 1986 to June 1987, in 640 patients submitted to surgical treatment at the São Francisco Hospital, in Ribeirão Preto, São Paulo, Brazil. The overall incidence of infection was 10.31%.

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.

[Barrett esophagus following peptic and alkaline esophagitis].

Eight cases of Barrett's esophagus are presented, six as a result of long-term reflux esophagitis, three of them with ulcer in gastric-like mucosa, two with stenosis. The Congo-Red test in three patients showed non-secretory pattern. They could twice confirm the epithelial change in previous normal esophageal mucosa, once after alkaline reflux esophagitis in a patient with total gastrectomy and esophagus-jejunostomy.

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.
