    Abstract:
    Basing on the establishment of an isolated bowel segement (IBS) in Beagle dog by omentoenteropexy, the possibility of using omentum as vascular pedicle in bowel elongation was investigated. Five young Beagle dogs (3 females, 2 males) with a body weight of 5-9 kg were used. A longitudinal incision (15 cm long) was made down to the seromuscular layer of the jejunal segment on the antimesenteric border, 20 cm distal to the duodenojejunal fold, the mucosal layer should never be injured. Then the free margin of the omentum was attached to the seromuscular border of the jejunum by interrupted sutures. One dog died from volvulus and necrosis of the bowel 3 days after operation. Seven weeks later, the mesentery was ligated in one dog and the bowel lengthening procedure was carried out in the other 3 dogs. The procedure consisted of longitudinal splitting of the isolated bowel segment anteroposteriorly, thus two separated segments of bowel were obtained, each received its own blood supply from either omental or mesenteric blood vessels. Either of the longitudinally splitting segments was rebuilt into one intestinal canal by 3/0 non-traumatic sutures. Then isoperistaltic end-to-end anastomosis of these two isolated segments was carried out, and an jejunostomy was established. The free jejunal ends were rejoined together to restore the continuity of the bowel lumen. Two weeks later, the blood supply of the experimental bowel segment was observed. It was shown that the IBS and elongated bowel segment (EBS) appeared viable, and there was good collateral circulation between the bowel segment and the omentum. The regeneration of lymphatics was observed from injection of methylene blue. It was concluded that a viable IBS and EBS could be established by using omentoenteropexy technique. The application of the this model in the management of short bowel syndrome needed to be further investigated.
