[An antiperistaltic duodenojejunal pouch in the reconstruction of digestive transit after subtotal and total gastrectomy and in the postgastrectomy syndrome. Results].

The author presents the results of a new surgical technique for the reconstruction of the gastrointestinal tract after gastrectomy. It was utilized in 36 patients (ten with total, 16 with subtotal and seven with minimal radical gastrectomy and also three cases of post-gastrectomy syndrome). The initial methodology, using the lost tie (group striction (GST)) to the duodenojejunal reservoir was not successful since it showed recanalization and consequent refluxing esophagitis (55,5%). For that reason, we changed to a complete section of the intestinal loop (group section (GS)). The follow up period ranged from one to 49 months. The following complications were observed: incisional hernia, one case (GST); early postoperative period death (19th day), one case (GS); dumping syndrome, one case (GST); bilious vomiting, two cases (GS); diarrhea, four cases (one GST and three GS). Clinically, in the late follow up of patients without recurrency of neoplasia, 17 of them have gained weight, four have lost weight and two were unaltered. Laboratory tests such as amilasemia, hematologic, proteins and glycemia were favorable to the method. Postoperative function, studied roentgenologically, showed that the average time emptying of the remmant stomach was 115 minutes in the subtotal resections and 82 minutes in total resections. The filling of the reservoir by the barium solution ranged from 40 to 60%; this variation depended on whether the duodenum was in peristalsis or antiperistalsis. Late death occurred in 13 patients, none because of the proposed technique.
