EFFETTI DELLA RESEZIONE GASTRICA SECONDO BILLROTH II SULLA ESOFAGITE DA REFLUSSO ASSOCIATA ALL'ULCERA DUODENALE O PILORICA

Although duodenal ulcer and reflux esophagitis may frequently co-exist, it is not clear whether surgery for duodenal ulcer associated with reflux esophagitis should not be associated with anti-reflux plastic surgery. The authors make a retrospective evaluation of the prevalence of reflux esophagitis (endoscopic diagnosis) in a consecutive series of 633 patients undergoing elective gastric resection according to Billroth II for duodenal or pyloric ulcer during the period 1974-1992 and assess the effects of surgery on co-existent esophagitis. The prevalence of reflux esophagitis associated with duodenal or pyloric ulcer was 12.3%. In patients in whom stenosis represented the indication for ulcer surgery, the prevalence of esophagitis was 20%, whereas it was 5% in those operated because of failure to respond to medical therapy of hemorrhage (p = 0.000001). In 95% of patients, controlled endoscopically 6 months after surgery, Billroth II gastric resection led to the resolution or improvement of associated esophagitis. The authors conclude that by eliminating the main pathological factors of reflux esophagitis associated with duodenal ulcer (hypersecretion of gastric acid, impeded gastric emptying) gastric resection is sufficient to achieve the resolution of esophagitis.
