Motility abnormality in dogs with gastrojejunostomy

Abstract

Motility related to gastrojejunostomy were studied in seven dogs which were prepared with a gastric cannula and platinum electrodes placed in the antrum, duodenum, jejunum and ileum. Five dogs were equiped with gastrojejunostomy at the time of electrode implantation and the two remaining dogs were used as control. Myoelectric activity recorded revealed several abnormal findings and occasionally spike activity occurred simularenously in the duodenum, jejunum and ileum or it retropropagated from lower ileum to reach the stomach. The study suggests that the dyspeptic symptoms observed in patients after gastrojejunostomy may be associated with similar motility abnormalities as observed in these dogs.
