Age and morbidity of vagotomy with antrectomy or pyloroplasty

Seven hundred ninety-three vagotomies with either pyloroplasty (645 patients) or antrectomy (148 patients) were reviewed between 1970 and 1981. Mortality was lowest with elective pyloroplasty (0.4 percent) followed by elective antrectomy (0.7 percent), and emergency pyloroplasty (5.1 percent). The risk of death was significantly higher (p < 0.05) for the older half of the population (older than 55 years of age). Major morbidity was lowest after elective pyloroplasty (6.3 percent) when compared with elective antrectomy (10.6 percent), and greatest after emergency pyloroplasty (18.1 percent). Proved ulcer recurrence was most frequently seen after pyloroplasty (4.5 percent) and least frequently seen after antrectomy (1.4 percent). Older patients (older than 55 years of age) had a significantly decreased risk of ulcer recurrence (p < 0.001). Disabling sequelae occurred in 3.6 percent of those who underwent pyloroplasty, in 5.6 percent of those who underwent antrectomy with Billroth I reconstruction, and in 8.5 percent of those who underwent antrectomy with Billroth II reconstruction. Significantly more patients who underwent antrectomy with Billroth II reconstruction required reoperation (p < 0.01) than did those who underwent either pyloroplasty or antrectomy with Billroth I reconstruction. Although antrectomy has become a popular operation, vagotomy combined with pyloroplasty is still the procedure of choice in patients over the age of 55 years, in those requiring emergency operations for duodenal ulcer, and in those in whom antrectomy is technically difficult because of a badly scarred duodenum. Billroth II reconstruction should be avoided after vagotomy and antrectomy.
