title: Clinical and radionuclide evaluation of Roux-Y diversion for postgastrectomy dumping.
abstract: From 1973 to 1986, 22 patients underwent Roux-Y gastrojejunostomy for the early postgastrectomy dumping syndrome. In the early years, five patients underwent Roux-Y conversion with the addition of a 10 cm antiperistaltic jejunal segment interposed between the Roux-Y limb and the stomach. Within 4 years, all five patients had the jejunal segment removed due to severe symptoms of gastric retention. These patients underwent reconstruction to create Roux-Y limb only and joined the pool of 17 patients who underwent Roux-Y diversion only for the dumping syndrome. Overall, 19 of 22 patients (86 percent) had almost complete resolution of their dumping symptoms on long-term follow-up. Three patients showed no improvement, two with severe gastric retention and one with recurrent dumping symptoms. Overall, 5 of 22 patients (23 percent) had moderate to severe early and late postoperative gastric retention necessitating medical treatment in three and subsequent near-total gastrectomy in two. Although other procedures such as pyloric reconstruction or the addition of isoperistaltic or antiperistaltic jejunal interpositions have been reported to be equally successful in delaying gastric emptying and resolving dumping symptoms, we have preferred Roux-Y diversion for the treatment of combined alkaline reflux gastritis and dumping or the pure early vasomotor postgastrectomy dumping syndrome. As reported, we have abandoned the use of an antiperistaltic jejunal segment interposed between the stomach and the Roux-Y limb due to the high rate of postoperative gastric retention.
