To observe the clinical outcome of laparoscopic page-turning complete mesocolic excision for patients with right hemicolon cancers.

From June 2010 to May 2019, clinical data of 68 patients with right hemicolon cancers were analyzed retrospectively . According to different surgical approaches, the patients were divided into the hybrid medial approach (HMA) group (n=30) and the " page-turning" complete medial approach (CMA) group (n=38). Statistical analysis were performed by using SPSS 21.0 software. Measurement data, such as perioperative indicators and other measurement data were expressed as (±s), and were examined by using independent test . Count data such as complications were examined by using chi square test. Kaplan-meier method were used for analysis of the 3-year disease-free survival (DFS) and overall survival (OS). A P value of <0.05 was considered as statistically significant difference.

(1) Compared with the HMA group, patients in the CMA group had shorter operation time, less intraoperative blood loss, and more harvested lymph nodes (P<0.05). (2) There was no significant difference between 2 groups in terms of incidence of postoperative complications (P>0.05). (3) There was no significant difference in terms of DFS (76.7% vs. 73.7%) or OS (83.3% vs. 81.6%) between the two groups 3 years after surgery (P>0.05).

The " Page-turning" CMA is more in line with the principle of tumor-free operation, with shorter operation time, less intraoperative blood loss and extended lymph node dissection, which has good clinical application value.
