Intestinal intussusception valve for postgastrectomy bile reflux and/or dumping.

The short-term results of a new surgical procedure for prevention of duodenogastric reflux and rapid gastric emptying after partial gastric resection are reported. A jejunal segment provided with an intussusception valve was interposed between the gastric remnant and the duodenum in six patients with severe postgastrectomy symptoms. Duodenogastric reflux, determined with an isotope derivative method, was found to be completely eliminated after the remedial operation. Gastric emptying of a glucose solution showed no significant delay. Previous gastroscopic findings of "gastritis" could not be recognized at postoperative examination. The histologic mucosal changes showed no remission, however. No patient became completely free from gastric symptoms after the remedial operation. The residual symptoms possibly were caused by impaired emptying of the gastric remnant. Gastric mycosis was found occasionally in all the patients during follow-up. The jejunal intussusception valve effectively prevented bile reflux and seemed to have a beneficial effect on dumping symptoms.
