Abstract：Objective：To observe the effect of transcutaneous electrical stimulation at Zusanli(ST 36) and Neiguan(PC 6) on rehabilitation of patients after radical resection for colorectal cancer under laparoscopy. Methods： A total of 50 cases of patients undergoing elective radical resection for colorectal cancer under laparoscopy were randomly divided into the study group and the control group， 24 and 25 cases in each group respectively. One case of patient in the study group did not complete all the experimental observation. Both groups had the same anesthesia scheme.， Transcutaneous electrical stimulation at Zusanli(ST 36) and Neiguan(PC 6) was conducted in the study group 30 minutes before surgery as well as on the 1st and 2nd days after surgery；the control group shared the same operation with that in the study group，but the power of the stimulation was off. The surgery time，bleeding volume，the stay time in post anesthesia care unit，the time of first anal exsufflation，postoperative non- incision pain such as shoulder pain，backache，and pain in intercostal muscle，scores of Visual Analogue Scale(VAS) for evaluating incision pain on the 4th，12th，24th，and 48th hours after surgery，and postoperative nausea and vomiting(PONV) were recorded in the two groups. Results：After treatment，the time of first exsufflation in the study group was significantly shorter than that in the control group， the difference being significant(P＜0.05)； when compared the surgery time，the stay time in post anesthesia care unit，and bleeding volume between the two groups，there was no significance in the difference(P＞0.05). On the 1st and 2nd days after surgery，the cases without PONV in the study group were significantly more than those in the control group， differences being significant(P＜0.05). After TEAS intervention，the cases without non-incision pain in the study group were significantly more than those in the control group， the difference being significant(P＜0.05). In the 24th and 48th hours after surgery， the VAS scores for evaluating pain in the study group were significantly decreased when compared with those at the previous time point in the same group， the difference being significant(P＜0.05)； the VAS score in the study group was significantly lower than that at the same time point in the control group(P＜0.05). Conclusion：Transcutaneous electrical stimulation at Zusanli(ST 36) and Neiguan(PC 6) can significantly improve postoperative analgesia effect on patients after radical resection for colorectal cancer under laparoscopy， reduce the occurrence of postoperative non-incision pain，relieve postoperative nausea and vomiting and shorten exsufflation time，which has certain promoting effect on accelerating postoperative rehabilitation.
