Influence of direct colon tissue electrical stimulation on colonic motility in anesthetized male Yucatan minipig

Direct proximal colon, transverse colon and colorectum wall electrical stimulation; monitor colon wall bio-impedance and colon manometry in all regions (proximal, transverse and distal) before, during and post stimulation.

对结肠近端、横结肠及结肠直肠壁实施直接电刺激；在刺激前、刺激期间及刺激后，监测所有区域（近端、横结肠及远端）的结肠壁生物阻抗（bio-impedance）与结肠测压指标。
