ABSTRACT
23 patients with chronic duodenal ulcer represented the subject of this study. Their ages ranged between 26 and 58 years with a mean of 42.8 years. Truncal vagotomy and mucosal pyloroplasty was done. The indication of surgery was medical intractability and complications of ulcer. All patients were operated upon at Al Zahraa University Hospital. Mucosal pyloroplasty was done by suturing the mucosa only and leaving the muscle layer unsutured so that complete muscle relaxation at the pyloric sphincter is achieved allowing adequate drainage from the stomach. There was no intraoperative difficulty even in obese patients. No mortality and none suffered from dumping, or fistula formation. Mucosal pyloroplasty is a simple, quick, safe and easy to perform with good results even in the presence of fibrosis. We recommend more studies to properly place this procedure as the st and ard drainage procedure
