nonresective surgery for gastro-duodenal ulcers ( gdu ) is the operation of choice in 95 % of cases of duodenal ulcer ( du ) and approximately 50 % of cases of gastric ulcer ( gu ) , with a good probability of permanent success if an adequate selective proximal vagotomy ( a-spv ) is combined with a pyloroplasty based on form and function ( ff-py ) .
