Acids contributed to 82.6% of chronic injuries. Chronic gastric injuries were usually one of five types in these patients. The majority had prepyloric strictures (83.5%). The remaining strictures were antral (4.6%), body (3.7%), pyloroduodenal (2.7%), or diffuse (5.5%).Twenty-one (22.8%) patients had a delayed gastric outlet obstruction, and18 patients had a concomitant esophageal stricture requiring a bypass. Most of the patients with chronic injury underwent surgical correction with Billroth I gastrectomy (77.1%), loop gastrojejunostomy (11.0%), and distal gastrectomy with Polya reconstruction (3.7%). Other procedures performed were pyloroplasty in 1 patient and colonic conduit jejunal anastomosis in 6 patients. One patient (1%) died in the postoperative period.
