[Postoperative reflux gastritis].

Postoperative reflux gastritis is generally considered a definite clinical syndrome. It is the possible sequel to any gastric surgery suppressing pyloric continence. Incidence of this complication is still difficult to evaluate, whereas enterogastric reflux is often seen during endoscopy. 75 patients were studied clinically and endoscopically, and their gastric mucosa histologically, after gastric surgery. Results were compared to those in a 2nd group of patients whose reflux induced symptoms had been brought under control by endoscopically confirmed surgical correction of reflux. Enterogastric reflux is common (80%), but its effect on the gastric mucosa is observed endoscopically only when it is relatively marked (69%). Clinical suspicion of reflux gastritis is most often confirmed by endoscopy, but endoscopic reflux gastritis is symptomatic in only half of patients undergoing surgery. Foveolar hyperplasia is the only histological criterion related to reflux gastritis.
