Abstract:Abstract: Objective?To discuss the impact of laparoscopic complete mesocolic excision (CME) on the operation effect and recovery of patients underwent radical resection of right colon cancer.?Methods?70 patients underwent radical resection of right colon cancer were selected from January 2015 to December 2017, according to the random number table method, they were divided into CME group and laparotomy group, 35 cases in each group. CME group was given laparoscopic CME treatment, and laparotomy group was given laparotomy treatment. The curative effect and recovery of the two groups were compared.?Results?The cortisol (COR), adrenocorticotropic hormone (ACTH) and epinephrine (E) in CME group and laparotomy group after operation were significantly higher than those before operation, the COR, ACTH and E in CME group after operation were significantly lower than those in laparotomy group, the difference was statistically significant (P?0.05). There was no significant difference in operation time, lymph node dissection and recurrence rate between CME group and laparotomy group (P?>?0.05), and the intraoperative bleeding volume, exhaust time, time out of bed, hospitalization time and complication rate in CME group were significantly lower than those in open group, the difference was statistically significant (P?0.05).?Conclusion?Laparoscopic CME has the good therapeutic effect on patients underwent radical resection of right colon cancer, and it can effectively reduce the surgical trauma and stress response of patients, which is conducive to reducing postoperative complications and promoting their physical recovery, it’s worth for further clinical promotion.
