Abstract
BACKGROUND:

Recently, an operative strategy involving complete mesocolic excision (CME) and central vascular ligation (CVL) for colonic cancer has been introduced. We aimed to describe our initial experience and assess the long-term outcomes of robotic modified CME (mCME) and CVL (mCME+CVL) for right-sided colon cancer.

METHODS:

Of the 677 patients with histologically confirmed, right-sided colon adenocarcinoma who underwent curative mCME+CVL between February 2008 and October 2016, 43 who were treated entirely using the robotic approach were included in this retrospective study. Survival rates were determined using the Kaplan-Meier method, and P values of < 0.05 indicated statistically significant differences.

RESULTS:

The total operation and docking times were 293 (180-644) min and 5 (3-19) min, respectively, with an estimated blood loss of 50 (10-400) mL. The time to soft diet was 4 (1-16) days and the length of hospitalization was 8 (4-48) days. Based on the Clavien-Dindo classification, grade I, II, IIIa, IIIb, and IV complications were noted in 3 (7.0%), 5 (11.7%), 2 (4.7%), 1 (2.3%), and 0 (0%) patients, respectively. The proximal and distal resection margins were 14 (4-54) and 19 (4-48) cm, respectively, and 29 (6-157) lymph nodes were harvested per patient. The patients were followed-up for a median of 55 (2-109) months, during which the overall survival rate, median disease-free period, disease-free survival rate, and tumor recurrence rate were 93.6%, 38 (2-109) months, 81.1%, and 16.3% (7 patients), respectively.

CONCLUSIONS:

Robotic mCME and CVL for right-sided colon cancer was feasible and safe. It can be added to the surgeon's toolbox as an optional strategy for the management of colon cancer patients.
