To explore the clinical outcome of improved medial approach in laparoscopic right hemicolectomy for patients with right colon cancer, including complications and quality of life.

From January 2014 and February 2017, clinical data of 86 patients who underwent laparoscopic right hemicolectomy were enrolled into study, including 43 cases in lateral approach group and 43 cases in medial approach group. All data were analyzed by using SPSS 21.0 software. Perioperative measurement data and tumor index were expressed as (±s), and were examined by using t test.The postoperative complication rate were analyzed by Chi-square test. A P value <0.05 was considered as statistically significant difference.

The number of harvested lymph nodes, intraoperative bleeding and the operation time of the medial approach group were (17.7±3.3), (55.7±36.1) ml and (122.4±25.6) min and were better than those of the lateral approach group respectively (P<0.05). 5 d post operation, colon cancer index in the medial approach group were lower than those in the lateral approach group, including Xiap, Livi, TK1 and Plk1 (P<0.05). In terms of life quality, scores of psychological and emotional status, subjective symptom and social activity in the middle approach group were shown to be higher than those in the lateral approach group, with statistically significant difference (P<0.05). The incidence of complications was 4.7% in the medial approach group and 7.0% in the lateral approach group, with no statistically significant difference between two groups (P>0.05).

Improved medial approach for right hemicolectomy could improve the patients’ quality of life and harvested lymph nodes, and could reduce the impact of postoperative malignant tumor with less postoperative complications.
