To investigate the clinical outcomes of Overlap anastomosis and FEEA in laparoscopic radical colon cancer resection.

The clinical data of 88 patients underwent total laparoscopic radical colon cancer resection from January 2018 to January 2020 were analyzed retrospectively. All of 88 patients were divided into the FEEA group (n=42cases) and the Overlap group (n=46 cases). Statistical analysis were performed by using SPSS18.0 software. The measurement data such as perioperative indicators, quality of life score (QOL) were expressed as (±s), the difference between the two groups were examined by using t test. The count data including postoperative complications were examined by using χ² test and the difference between the two groups were examined by using Fisher’s exact test. A P value of <0.05 was considered as statistically significant difference.

The operation time, postoperative exhausting and feeding time and the length of hospitliztion in the Overlap group were shorter than those in the FEEA group respectively (P<0.05). There were no significant difference between two groups in terms of blood loss, abdominal incision length, postoperative 24 h pain score, and quality of life on 1, 3 and 6 months after surgery (P>0.05). Additionally, there was no statistical significance in terms of total incidence of complications between two groups (11.9% vs. 4.3% P>0.05).

The Overlap anastomosis could reduce the operation time with enhanced the postoperative recovery and lower incidence of complications.
