探讨腹腔镜结直肠癌切除术(LRCC)术前不留置胃管对患者术后恢复的影响。

选择2016年1月至2018年10月收治的行LRCC患者100例进行临床实验研究，按照随机数字表法分为两组，各50例。对照组术前常规留置胃管，观察组术前不留置胃管，两组围术期其他干预措施相同。采用SPSS21.0进行统计分析，两组术后恢复指标、手术前后CRP水平均采用(±s)表示，独立t检验；两组术后并发症发生率采用χ²检验，P<0.05为差异有统计学意义。

观察组术后初次排气时间、初次肠鸣音时间、初次排便时间、初次下床时间、住院时间均短于对照组，住院花费低于对照组(P<0.05)；观察组术后2 d、3 d的CRP水平均低于对照组(P<0.05)；观察组腹胀腹泻、失眠、咽喉疼痛发生率低于对照组，差异均有统计学意义(P<0.05)。

行LRCC患者术前不留置胃管可减轻应激反应，降低并发症发生率，缩短住院时间，促进早日恢复，值得推广。

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.
