[Post-caustic gastric stenosis].

Two cases of postcaustic antropyloric stenosis are reported. The lesions developed 3 and respectively 5 weeks after ingestion of the caustic substance and surgery for complete stenosis was performed 35 and 56 days after the initial accident. In both cases antropylorectomy with gastroduodenoanastomosis of the Péan-Billroth type I, in two layers, was performed. Integrity of the esophagus and good function of the anastomotic mouth, appraised by the clinical symptomatology and evolution of the radiologic aspect, showed that at least in some cases it is possible to apply the curative intervention 5-6 weeks after the accident, without a previous shunt being necessary.
