Objective To explore the effect of sphincter of Oddi (SO) stenosis on myoelectric activities in dogs. Methods After fasted for 16-18 h
the adult mongrel dogs were anesthetized and mechanically damaged by surgery to make stenosis of sphincter of Oddi. Sphincter of Oddi electromyography (SOE) was used to detect electrophysiology at postoperative 4th week when the dogs were under general anesthesia. Then
the SO was resected for pathologic analysis. Results In the dogs of SO stenosis
liver function such as TBIL
direct bilirubin was higher and the diameter of CBD by ultrasonograph was larger than preoperative ones. The fibrosis of SO was observed pathologically. However
in the control dogs
no obvious changes were found in liver function
CBD diameter as well as SO status. The voltage amplitude of slow waves and spikes in the experimental dogs decreased compared with control ones. Conclusion The model of SO stenosis was established successfully. SO stenosis caused significant electrophysiologic changes.
