Abstract
The authors report their experimental studies on early nutritional changes in 30 gastrectomized rats where intestinal continuity was restored by three different reconstruction methods, i.e., exclusion of the duodenum from alimentary transit (Sweet‐Allen method), or duodenal recanalization (Longmire method) or double duodenal and jejunal recanalization (Moricca method). Ten sham operated rats were used as controls. Results showed that the group of rats which underwent Longmire's reconstruction presented better nutritional parameters (body weight gain, daily food intake, feeding efficiency, albuminemia) than the Moricca and Sweet‐Allen reconstruction groups. These results became statistically significant when follow up was extended to 18 months by using an actuarial method. However, perioperative mortality rate was highest in the Longmire reconstruction group.
