比较了腹腔镜和开放式乙状结肠切除术后胃肠动力的恢复情况。在手术过程中，双极记录电极被放置在近端和远端胃窦、中段和远端结肠以及直肠上。术后记录空腹肌电数据。在[术后第2天（POD）]手术前后，采用固体试验餐进行闪烁成像胃排空研究。术前给予10个不透射线标记物，每天通过腹部X线对保留的标记物进行计数。术后120 min开放组胃排空较术前明显延迟（P<0.05），术后2 min开放组胃排空较腹腔镜组明显延迟（P <0.01）。在POD 4时，各组间标记保留数差异显著（P<0.05）。在任何一天，两组之间的慢波频率、近端和远端胃窦中存在的节律障碍或结肠和直肠中存在的离散或连续电反应活动均无显著差异。我们的结论是，使用腹腔镜方法的结果更快地恢复进食状态胃肠动力结肠切除术后。这些数据还表明，单独的肌电活动不是检测该动物模型中恢复的这些差异的足够敏感的参数。
The recovery of gastrointestinal motility was compared in dogs undergoing either laparoscopic or open sigmoidectomy. During surgery, bipolar recording electrodes were placed on the proximal and distal antrum, mid- and distal colon, and the rectum. Fasting myoelectric data were recorded postoperatively. Scintigraphic gastric emptying studies employing a solid test meal were performed before and after [postoperative day (POD) 2] operation. Ten radiopaque markers were given just before operation and retained markers were counted daily by abdominal x-ray. Gastric emptying on POD 2 was significantly delayed in the open group at 120 min compared with preoperative studies for the open group and compared with the laparoscopic group on POD 2 (P<0.05 andP<0.01, respectively). A significant difference in the number of retained markers was observed between the groups on POD 4 (P<0.05). There were no significant differences in slow-wave frequency, presence of dysrhythmias in the proximal and distal antrum, or presence of either discrete or continuous electrical response activity in the colon and rectum between groups on any days. We conclude that using a laparoscopic approach results in more rapid recovery of fed-state gastrointestinal motility following colon resection. These data also suggest that myoelectric activity alone is not a sensitive enough parameter to detect these differences in recovery in this animal model.
