电针对Roux-en-Y吻合术后空肠袢肌电活动的影响

Effect of electroacupuncture on myoelectric activity of Jejunal limb after Roux-en-Y esophagojejunostomy

目的探讨Roux-en-Y吻合术后空肠袢肌电活动的变化及电针对它的影响。方法将自然条件基本相同的14只幼猪,随机分为两组,实验组(全胃切除、Roux-en-Y食管空肠吻合)和对照组(留置电极后关腹)各7只。实验组电针“足三里”。观察其肌电图的变化。结果食管空肠Roux-en-Y吻合组Roux空肠袢平滑肌肌电慢波振幅、慢波频率、峰电振幅及峰电发生率较对照组均有明显改变,移行性综合肌电(MMC)Ⅲ相时程为(2·6±0·7)min,较对照组的(7·1±1·1)min明显缩短。电针刺激后,对慢波振幅及慢波频率影响不大,但可明显刺激峰电的发生及提高峰电的振幅,电针后MMCⅢ相时程为(5·7±0·9)min,较电针前的(2·6±0·7)min明显延长(P<0·01)。结论电针“足三里”可通过影响空肠的肌电活动而减轻Roux-en-Y滞留综合征。

Objective To explore the effect of electroacupuneture 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 gastreetomy 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. Ruults 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 eleetroacupuncture. Conehmion Electroacupuncture at ＂Zusanli＂ （ST 36） can relieve the Roux-en-Y stasis syndrome through influaneing myoelectric activity of the jejunum.
