The motility of the descending colon was studied in nine patients before and after resection of the rectum for cancer. This operation parasympathectomises and generally also sympathectomises the remaining left colon. Motor activity was significantly reduced by sleep before and after surgery. There was also a reduction in awake motility after surgery which is attributed to extrinsic denervation. The reduced motility may explain the increased frequency of motions passed after surgery.
对9例因癌症行直肠切除术前、后的降结肠运动情况进行了研究。该手术会使剩余的左半结肠发生副交感神经切除,通常也会发生交感神经切除。手术前后睡眠均会显著降低运动活性。术后清醒时的运动活性也降低,这归因于外在去神经支配。运动活性降低可能解释了术后排便次数增加的原因。
