During a twenty-six year period from 1973 to 1999 a total of 78 patients with severe esophago-gastric lesions after caustic ingestion were referred to and managed at our unit. Hydrochloric acid was the most frequently involved caustic agent and the lesions were located in the esophagus (52.6%), in the stomach (19.2%) and in both the esophagus and stomach (28.2%). Thirty-seven patients were managed by endoscopic dilation of esophageal stricture that gave permanent relief of dysphagia in 13 cases only. Twelve patients are still managed with endoscopic dilation and in another 12 we performed bypass surgery. Two perforations developed and spontaneously sealed after T.P.N. for 6-8 weeks. No death occurred. Fifty-three patients were operated on in emergency or during survey period or for stenotic lesions. Surgical procedures were: in esophageal strictures a substernal esophago or pharyngocologastroplasty without esophagectomy; in esophago-gastric strictures, after an esophago-gastrectomy, an esophago or pharyngocolojejunoplasty in one or two steps; in total gastric stenosis without esophageal involvement a total gastrectomy followed by a Roux-en-Y esophago-jejunal anastomosis and in antropyloric strictures a Billroth I or II partial gastrectomy. The morbidity rate was 32% with a 5.6% mortality rate.
