[Effect of electroacupuncture on myoelectric activity of Jejunal limb After Roux-en-Y esophagojejunostomy].
OBJECTIVE
To explore the effect of electroacupuncture on myoelectric activity of Jejunal limb after Roux-en-Y esophagojejunostomy.


METHODS
Fourteen health young pigs were randomly divided into 2 groups, an experimental group (total gastrectomy and Roux-en-Y esophagojejunostomy was carried out) and a control group (the abdominal cavity was closed after the electrode was placed), 7 pigs in each group. Electroacupunture was given at "Zusanli" (ST 36) in the experimental group. The changes of myoelectrogram of the jejunal limb was investigated.


RESULTS
Compared with the control group, the amplitude and the frequency of the slow wave, and the amplitude and incidence rate of the spike potential in the experimental group were changed significantly; the duration of migrating motor complex (MMC) phase III was (2.6 +/- 0.7) minutes in the experimental group, which was significantly shorter than (7.1 +/- 1.1) minutes in the control group. Electroacupuncture did not significantly influence the amplitude and the frequency of the slow wave, but could increased significantly the incidence rate and the amplitude of the spike potential; after electroacupuncture, the duration of MMC phase III was (5.7 +/- 0.9) minutes, which was significantly longer than (2.6 +/- 0.7) minutes before electroacupuncture.


CONCLUSIONS
Electroacupuncture at "Zusanli" (ST 36) can relieve the Roux-en-Y stasis syndrome through influencing myoelectric activity of the jejunum.
