Abstract
BACKGROUND
To prevent or minimize postgastrectomy complications, proximal gastrectomy with an interposed jejunal pouch has been advocated as an organ-preserving surgical strategy to improve quality of life for the patients. However, the utility of this surgical method has only been evaluated clinically and no reports have been published concerning animal studies. Therefore, we carried out an experiment in beagle dogs to investigate the utility of proximal gastrectomy with an interposed jejunal pouch.
METHODS
Female beagle dogs weighting 8.0-10.0 kg were divided into two groups that underwent proximal gastrectomy with jejunal pouch interposition (JP group) and esophagogastrostomy (EG group). The time course of the electrophysiological changes on electromyograms were compared between the JP and EG groups.
RESULTS
Electrophysiologically, a significant difference was noted between the two groups on the number of action potentials per unit time, the mean amplitude, and the length of the resting period in the preprandial state. All parameters tended to be normalized sooner after surgery in the JP group.
CONCLUSIONS
The clinical superiority of jejunal pouch interposition was suggested experimentally to the same extent on electromyograms.
