SMALL-BOWEL ANASTOMOSIS WITH THE BIOFRAGMENTABLE ANASTOMOSIS RING AND MANUAL SUTURE - A PROSPECTIVE, RANDOMIZED STUDY

A total of 170 patients undergoing upper gastrointestinal surgery requiring a jejuno-jejunal enteroanastomosis were randomized into two groups according to the method to be employed at the enteroanastomosis. The most common procedures were partial gastrectomy for benign disease (84 patients), partial or total gastrectomy for malignant disease (35 patients), and bilioenteral bypass (31 patients, 25 for malignant disease). The enteroanastomosis was created by manual suture (3-0 Dexon(R), two layers) in 89 patients and with the Biofragmentable Anastomosis Ring (Valtrac-BAR(R)) in 81 patients. Both end-to-side (101 patients) and side-to-side (69 patients) reconstructions were done. No ruptures or obstructions of the jejuno-jejunal anastomosis occurred. The postoperative recovery of the gastrointestinal tract was similar in the two groups in duration of nasogastric drainage, intravenous fluid therapy, and intestinal paralysis. Nor was there any difference between the groups in the duration of the postoperative hospital stay. Ten patients, 7 in suture-group and 3 in BAR-group, died postoperatively of causes unrelated to the enteroanastomosis. Thus the mortality rate was 7.9% in the suture group and 3.7% in the BAR group. The biofragmentable ring offers a safe alternative to manual sutures for small bowel anastomoses.
