Thirty-seven patients with recurrent ulceration after vagotomy were treated by Polya gastrectomy and have been followed up for a minimum of 3 years (median 5 years).

The results of Polya gastrectomy were Visick grade I: 61 per cent, Visick grade II: 15 per cent, Visick grade III: 9 per cent and Visick grade IV: 15 per cent, Two patients had further recurrent ulceration.
