IntroductionAfter a partial resection of the stomach, the continuity of the gastrointestinal tract can be restored either by a Billroth II gastrojejunal anastomosis or a Roux-en-Y gastrojejunostomy. Each procedure has its advantages and disadvantages.ObjectiveTo determine through a prospective and random clinical trial, the clinical outcome and the endoscopic and histologic alterations of the distal esophagus and the gastric remnant in patients who received a partial distal gastrectomy due to duodenal ulcers and a Billroth II or Roux-en-Y reconstruction.Material And MethodsIn this prospective random trial, a total of 75 patients with duodenal ulcers were included. A bilateral selective vagotomy and partial distal gastrectomy were performed in all patients. A Billroth II or Roux-en-Y 60-cm-long loop was randomly used for reconstruction of the gastrointestinal tract. During the latest follow-up clinical evaluation, upper endoscopy and biopsy samples from the distal esophagus and gastric remnant were obtained.ResultsThere was 1 operative mortality and 6 patients had some morbidity. The average follow-up period was 15.5 years (range, 11-21). Patients with Roux-en-Y gastrojejunostomy were significantly more asymptomatic and had greater Visick I grading than patients with Billroth II reconstruction (P < 0.001). In the distal esophagus, endoscopic findings were normal in 90% of the Roux-en-Y group, but only in 51% of the Billroth II group (P < 0.0009). Nearly 25% of the latter group had the appearance of a short-segment Barrett esophagus compared with 3% of the Roux-en-Y group (P < 0.0001). The gastric remnant endoscopic findings were normal in 100% of the Roux-en-Y group and in 18% of the Billroth II group (P < 0.02). Histologic analyses showed similar proportions of normal fundic mucosa and chronic active fundic gastritis. However, chronic atrophic fundic gastritis and intestinal metaplasia were significantly more frequent after Billroth II reconstruction (P < 0.008). Helicobacter pylorus was present in a similar proportion of patients.ConclusionsThis prospective and random study showed that Roux-en-Y gastrojejunostomy is significantly better than a Billroth II reconstruction in patients with duodenal ulcers, through subjective and objective endoscopic and histologic evaluations during the latest follow-up evaluation.
