RESUMO

The duodenogastric reflux is a phenomenon know around 100 years. In the beggining it was considered verified that the reflux caused inflamation on the gastric mucosa. Later the reflux gastritis was observed in patients submitted to gastrojejunostomy or gastrectomy. Since then, several clinical and experimental studies were realized to reach better knowledge about this pathology. Most of the authors believe that since 1947 the alkaline reflux gastritis became a well estabilished clinical entity and accepted as a pos-gastrectomy syndrome different from the others. In the present paper we intended to verify if leading the bile to the gastric antrum or gastric corpus, it caused gastritis in different frequency and intensity. Moreover, if the truncal vagotomy would be able to protect the gastric mucosa from the noxious effects of bile and gastric juice. With this objective we operated 40 dogs in which was performed an anastomosis between the gallblader and the stomach, after ligadure double of the choledocus. In a group of twenty animals, in ten of them this anastomosis was done in the antrum gastric, and in the ten others in the corpus. In another group of dogs the same surgeries were made in twenty dogs, but added of a bilateral truncal vagotomy. In ten of them the anastomosis was done in antrum and in the other ten in the gastric corpus. All the animals were sacrificed 180 days after the surgeries. The macroscopic and microscopic studies of the specimes revealed the gastritis was less frequent and less intense in the dogs that were submitted to the vagotomy. So the vagotomy was able to protect the gastric mucosa from the deleterious effects of the bile and chloridric acid and pepsin of the gastric juice. We noted also the inflamatory process was more intense when the anastomosis was made in the antrum than the corpus in all the animals, submitted or not the vagotomy. Other aspect observed in this paper was that the gastritis, in some dogs, was more intense aroud the anastomosis
