.17, respectively. Recurrence rate found relatively greater in LCA plus MMC group compared to of LCA plus LMA but haven't reached statistical significant, 16.6% vs. 10.52%, p=0.56, respectively. 5-year disease-free survival and overall survival rate were similar in both groups. Conclusion:Higher level of vessel ligation has not add significant different in overall outcome, however, has a potential role to lower the risk of recurrence rate in SFC patients.enhanced overall survival up to 15.6% when dissection take place in embryological planes. Moreover, central venous ligation and division of feeding vessel at the root have shown a successful concept to retrieved higher number of lymph node metastasis [8]. On top of that, higher number of lymph node harvested attributed in accurate staging [9]. CME principles for right-sided resection equivalent to the current TME principles for left sided resection. Therefore, optimal vessel ligation has been discussed and studied well in the right-sided colon cancer with anticipated success to achieve oncological benefits. However, guideline to determine the level of vessel ligation in SPC is still remained in debates. The concept of high vessel ligation is to include resection of the paracolic nodes, intermediate nodes and apical lymphnodes, which defined as D3 lymph-adenectomy. D3 lymph-adenectomy have been widely used and accepted in Japan, China and Korea [10][11][12]. In case of SFC, whether high level of vessel ligation is required to include LMC artery or not, yet has not been proposed. To our knowledge, this is the first study aiming to investigate the adequacy of vessel ligation in SFC in term of overall survival (OS) and local recurrence. Materials and Methods Patients
