To investigate the approach selection and clinical efficacy of three-dimensional high-definition laparoscopic radical resection of right colon cancer.

From May 2015 to August 2017, clinical data of 96 patients with right colon cancer were analyzed retrospectively. According to different approaches, they were divided into lateral approach group and intermediate approach group, 54 cases and 42 cases, respectively. Data analysis was performed by using statistical software SPSS22.0. Measurement data such as surgical indicators were expressed as (±s) and were examined by independent t test. The incidence of complications, conversion rate and survival rate were examined by chi square test. A P value of <0.05 was considered as statistically significant.

The operation time, intraoperative blood loss and exhaust time in the lateral approach group were shorter than those in the intermediate approach group repectively (P<0.05). There were no significant differences in analgesia time, hospitalization time and number of lymph node dissection between the two groups (all P>0.05). The total incidence of complications in the lateral approach group was 3.7%, which was lower than that in the middle approach group (11.9%), however without significant difference (P>0.05). The conversion rate to open surgery in the lateral approach group was 3.7%, which was lower than that in the intermediate approach group (16.7%), with significant difference (χ² = 7.080, P<0.05). There were no significant differences of median survival, 1-year recurrence rate and 1-year survival rate between the two groups (all P>0.05).

Laparoscopic radical resection of right colon cancer through lateral approach could shorten the operation time, reduce the amount of bleeding and exhaust time, and could effectively reduce the conversion rate to open surgery, with equivalent prognosis as well as the intermediate approach. It is worthy of promotion and application in the radical resection of right colon cancer.
