To investigate the effect of caudal middle combined approach and caudal approach in laparoscopic radical resection of right colon cancer.

Data of 105 patients with colon cancer who underwent laparoscopic radical resection of right half colon cancer from February 2017 to February 2022 were retrospectively analyzed. They were divided into two groups according to different surgical approaches. The caudal group (caudal approach, n=52 cases) and the combined group (caudal middle approach, n=53 cases) were analyzed using SPSS 25.0 statistical software. Measurement data such as surgical indicators and postoperative recovery indicators were represented by (), and independent sample t test was performed. Complications were counted by chi-square test. P < 0.05 was considered statistically significant.

Compared with caudal group, the combined group had less blood loss and more lymph node dissection (P < 0.05). There was no significant difference in operation time and conversion rate between the two groups (P > 0.05). Compared with caudal group, the recovery time of exhaust, defecation and feeding was shorter in combined group (P < 0.05). There was no significant difference in postoperative drainage tube removal and hospital stay between the two groups (P > 0.05). Within 30 days after surgery, there was no significant difference in the incidence of postoperative complications between the two groups (P > 0.05).

The safety of caudal median combined approach is comparable to that of caudal laparoscopic radical resection of right half colon cancer, but caudal median combined approach is more advantageous in reducing intraoperative blood loss, removing lymph nodes and promoting gastrointestinal function recovery.
