Neopylorus: a functional reflux-free gastroenteral anastomosis.
To minimize the loss of pyloric function associated with partial gastrectomy (PG), a functional surrogate pylorus, or neopylorus, was made by means of a pantaloon jejunoplastic pouch into which the gastrojejunal stoma was invaginated. This report concerns a consecutive series of 84 patients who underwent PG according to currently accepted criteria. The results showed that formation of the neopylorus apparently prevents dumping and may avoid the necessity for vagotomy in cases without serious hypersecretion. PG patients with a neopylorus formed over 13 years ago still exhibit no enterogastric reflux, gastritis, anaemia, steatorrhoea or sequelae of impaired digestion. Patient satisfaction has been most encouraging. Because this report is a feasibility trial only, no statistical analysis is presented.
