  • Title: The effect of vagotomy antrectomy or vagotomy pyloroplasty on the response of the antrum to meat extract in duodenal ulcer patients.
    Author: Coutsoftides T, Himal HS.
    Journal: Ann Surg; 1976 Aug; 184(2):212-6. PubMed ID: 952567.
    Abstract:
    In 9 normal and 42 duodenal ulcer patients, acid and gastrin studies were performed. Basal, Oxo and Histalog stimulated acid secretion was conducted on each patient. In 24 patients post vagotomy pyloroplasty or vagotomy antrectomy, these studies were repeated within three months after surgery. Two groups of duodenal ulcer patients were identified; those who did respond and those who did not respond to Oxo stimulation. In the "responders," Oxo stimulated acid output and gastrin secretion increased significantly over basal values. Both vagotomy pyloroplasty and vagotomy antrectomy caused a similar significant decrease in Oxo and Histalog stimulated acid output. In two patients with incomplete vagotomy, antrectomy, but not pyloroplasty abolished the Oxo stimulated acid response. These data suggest that OXO stimulation test can select patients with a significant antral component in whom vagotomy and antrectomy would be the appropriate procedure. Our results also indicate that antrectomy will protect against recurrent ulceration in patients with incomplete vagotomy and may explain the lower incidence of stomal ulceration in patients with vagotomy antrectomy, compared to vagotomy pyloroplasty.
