RESUMEN
This study was carried in the Surgical Department of Kasr El-Aini University Hospital over a period extending from November 1995 through December 1998. Twenty patients suffering from chronic duodenal ulccration, 14 males and 6 females, with a mean age of 38.8 years, who presented for surgery, were included in the study. The indications for surgery constituted failure of long term medical treatment [12 cases], complications [4 cases], frequent relapses [2 cases]. Pre-operative endoscopic biopsy from the gastric antrum revealed positive H.pylori infestations in all cases. 3 months following trunkaI vagotomy and gastroentcrostomy, re-endoscopy revealed healing of the ulcers in all cases. Biopsies obtained from within one inch of the gasto-enterostomy revealed however, persistence of H. pylori in 40% [8] of cases
