Twenty years after parietal cell vagotomy or selective vagotomy antrectomy for treatment of duodenal ulcer. Final report.

OBJECTIVE

This study was a prospective, randomized evaluation of parietal cell vagotomy (PCV) and selective vagotomy-antrectomy (SV-A) in the treatment of duodenal ulcer.

BACKGROUND DATA: Operative treatment of duodenal ulcer is associated with mortality and mechanical and metabolic morbidity. At the time that surgeons appear to have succeeded in developing operations with low morbidity and mortality, the number of patients requiring elective operation has decreased partly because of the simultaneous, dramatic improvement in medical therapy. Nevertheless, surgical therapy still is important, especially in certain socioeconomic environments.

METHODS

After a pilot study of PCV, 200 patients with duodenal ulcers were randomized to PCV or SV-A. One surgeon was responsible for the operations and follow-up studies. An attempt was made to evaluate all patients annually in the hospital. Gastric analyses were performed on each visit, for which the patient gave his/her consent.

RESULTS

There was no operative mortality. The recurrence rate-by-life table analysis was less (p < 0.003) after SV-A than PCV. Dumping was greater (p < 0.001), and there was no difference in the frequency of diarrhea after SV-A compared with PCV. The percentage of patients with grades Visick I or Visick II was not different for the two operations, but more patients were graded Visick I after PCV than after SV-A.

CONCLUSIONS

Selective vagotomy-antrectomy and parietal cell vagotomy are effective and safe operations, when used appropriately. Selective vagotomy-antrectomy is preferable for patients with pyloric and prepyloric ulcers and pyloric obstruction. Parietal cell vagotomy is the authors' choice for duodenal ulcer patients because of the occasional patient who becomes disabled by SV-A.
