The slow wave (SW) was studied in the dog intestine after a 15 cm long jejunal resection, by means of an automatic method which measures each individual SW cycle duration, the SW mean period and its standard deviation during 3 postoperative weeks. Distal to the site of anastomosis, the SW frequency dropped. 3 weeks after the resection, it was partially restored. The standard deviation increased as well caudad as orad to the anastomosis when compared to control dogs. The differences with the controls were even enhanced with time. These results suggest that the intestinal motility is altered at least during 3 weeks after a jejunal resection.
通过一种自动方法研究了犬空肠切除15厘米后小肠慢波（SW）的情况，该方法可测量术后3周内每个单独的SW周期持续时间、SW平均周期及其标准差。在吻合口远端，SW频率下降。切除术后3周，其部分恢复。与对照犬相比，吻合口尾侧和头侧的标准差均增加。与对照的差异随时间甚至进一步增大。这些结果表明，空肠切除术后至少3周内肠道运动发生了改变。
