Interventions/Control_1

1)Single incision laparoscopic surgery: All trocars passes a special platform via a single wound. Addition of one trocar because of transection of colon or insertion of drainage tube is allowed. It is defined when there are addition of two trocars or more as the conversion into the multi-port surgery. The application of Colon lifting technique of the securing purpose of counter traction is allowed.

Interventions/Control_2

2) Multiport laparoscopic surgery: The ports are set up up to 4-5 places at the time of beginning the operation. *When the wound length is 8cm or more, it is defined as the conversion to the open surgery.

Results

SILC is not superior to MPLC.
1.Even though the results of the 5-year OS and RFS in this trial were exploratory and underpowered, there were no statistically significant differences between the SILC and MPC arms. SILC may be an acceptable treatment option for select patients with colon cancer.

RESULT:
2.Single-incision laparoscopic colectomy was similar to multiport laparoscopic colectomy in terms of health-related quality of life and patient satisfaction. However, single-incision laparoscopic colectomy may be inferior than multiport laparoscopic colectomy in terms of the role emotional.
3.We found no significant difference in the incidence of incisional hernia after SILC arm versus MPC arm with a long-term follow-up. However, this result may be biased because all specimens were harvested through the umbilical port.
