Abstract
Anterior lesser curve seromyotomy with posterior truncal vagotomy (ASPTV) provides a simple, safe and expeditiously performed method of denervating the parietal cell mass, whilst preserving the pylorus. Dumping and diarrhoea are uncommon after this procedure. Gastric emptying has been assessed after ASPTV and other elective operations for duodenal ulcer. Liquid and solid phase gastric emptying studies were performed in control subjects (17), patients before and at least six months after ASPTV (14), vagotomy and pyloroplasty both without (8) and with (6) diarrhoea, vagotomy and gastroenterostomy (11), and Polya gastrectomy (7). There was no delay in emptying time for liquids or solids between ASPTV patients and controls. With the exception of an increase in the early emptying of liquids (P = 0·02) after ASPTV, gastric emptying was not different from normal. After truncal vagotomy and pyloroplasty in patients without diarrhoea the gastric emptying of solids, but not of liquids, was markedly increased (P = 0·00001), whereas in those with diarrhoea both liquid and solid phase emptying were markedly increased (P < 0·001). When gastroenterostomy was used as the drainage procedure both phases of emptying were increased. After Polya gastrectomy, both early and late emptying of liquids and solids were increased (early phase P < 0·05, overall emptying P < 0·001).
