Abstract: This study explored the application value of multi-slice spiral CT three-dimensional reconstruction (3D-MSCT) in laparoscopic radical resection of right colon cancer. Collected 100 patients with right colon cancer, among them there were 61 patients with 3D-MSCT before operation (the observation group) and 39 patients (control group) underwent routine CT examination. The preoperative T stage and N stage of the two groups were analyzed. The Kappa values of preoperative T stage and pathological stage in observation group and control group were 0.821 and 0.758, respectively (P<0.05), and the Kappa values of preoperative N stage and pathological stage were 0.825 and 0.813, respectively, P<0.05. The accuracy of preoperative T stage in observation group and control group were 88.52% and 84.62%, and the accuracy of preoperative N stage was 90.16% and 89.74%, respectively, and there was no significant difference (P>0.05). The operation time of the observation group was significantly shorter than that of the control group, and the intra-operative blood loss and the proportion of vascular injury were significantly lower than those of the control group (P<0.05). The levels of serum gastrin (GAS) and motilin (MTL) in the observation group were significantly higher than those in the control group (P<0.05), while the levels of cortisol (Cor) and adrenal corticotropin (ACTH) were significantly lower than those in the control group (P<0.05). In laparoscopic radical resection of right colon cancer, multi-slice spiral CT three-dimensional reconstruction is helpful in providing comprehensive information for the operation, avoid accidental vascular injury, and have little impact on patients' body stress and gastrointestinal function.
