title: Cholelithiasis follows total gastrectomy in Zollinger-Ellison syndrome.
abstract: The frequent occurrence of cholelithiasis noted in the follow-up of patients who underwent total gastrectomy because of Zollinger-Ellison syndrome prompted us to study this phenomenon. Cholelithiasis is known to be more common after truncal vagotomy, with or without concomitant subtotal gastric resection, and the prevalence of gallstones in these patients is reported to be 16% to 38%. To date, however, no long-term study has investigated the prevalence of gallstones after total gastrectomy in patients with the Zollinger-Ellison syndrome. Since 1961, 26 patients with the Zollinger-Ellison syndrome have undergone total gastrectomy and were enrolled in a Medical College of Wisconsin Clinical Research Center protocol that allowed follow-up to assess the development of cholelithiasis. Eight patients had cholecystectomy at the time of total gastrectomy (seven patients had stones), leaving 18 patients with a normal gallbladder and no gallstones at the time of total gastrectomy. Four patients died early, two of surgical complications, one of tumor progression, and one of alcohol-related trauma. During follow-up, cholelithiasis has developed in 10 of 14 patients (71%) at risk; the mean time to gallstones was 6.3 years (range, 1.2 to 12.9 years). The predictable occurrence of cholelithiasis after total gastrectomy in patients with the Zollinger-Ellison syndrome suggests that cholecystectomy should be performed at the time of total gastrectomy.
