To investigate the effect of no indwelling gastric tube before laparoscopic colorectal cancer resection on the patients’ postoperative recovery.

A total of 100 patients underwent laparoscopic colorectal cancer resection in two hospitals from January 2016 to October 2018 were enrolled in this clinical trial. 100 patients were divided into two groups (50 cases in each group) by using the random number table method. Patients in the control group routinely receive gastric tube before surgery, while patients in the observation group did not receive gastric tube before operation. The other intervention measures were the same in both two groups. SPSS21.0 software were used for statistical analysis. Measurement data such as postoperative recovery indicators and perioperative CRP level were expressed as mean±standard deviation and were examined by independent t test. Count data such as the incidence of complications after operation were described by (n, %) and were examined by chi square test. A P value of <0.05 was considered as statistically significant.

In the observation group, the time of first exhaust, first bowel sounds, first defecation, first ambulation time and hospitalization were less than those in the control group respectively, and the hospitalization cost was lower than that in the control group, with significant difference (P<0.05). The CRP levels in the observation group were lower than those in the control group on 2 and 3 days after operation (P<0.05). The incidence of abdominal distension, diarrhea, insomnia and sore throat was lower in the observation group than those in the control group, with significant difference (P<0.05).

For patients undergoing laparoscopic colorectal cancer resection, gastric tube is not necessary before surgery, without it might reduce the stress response, decrease the incidence of complications, shorten the length of hospital stay, and could promote early recovery, which is worth of promotion.
