ABSTRACT
OBJECTIVE: To investigate the feasibility and short-term outcomes of laparoscopic D3 lymphadenectomy along the left of SMA for right colon cancer.METHODS: The clinical data of 134 patients with right colon cancer admitted from June 2015 to March 2017 in Department of Gastrointestinal Surgery,Ruijin Hospital,Shanghai Jiao Tong University School of Medicine were analyzed retrospectively. A total of 57 patients received the laparoscopic D3 lymphadenectomy along the left of SMA and 77 patients received the laparoscopic D3 lymphadenectomy along the left of SMV.RESULTS: There was no statistical difference between the two groups in operation time,intra-operative blood loss,time of liquid intake and post-operative hospital stay,but the SMA group had a longer duration of tube drainage and larger total volume of drainage[(471.4±285.6)mL vs.(352.2±305.7)mL,(7.0±4.9)d vs.(5.7±2.0)d,P=0.02 和 P=0.03]. The SMA group harvested more lymph nodes than the SMV group(26.5±6.7 vs. 21.3±7.8,P<0.0001). However,the SMA group had a higher rate of post-operative complications(28.1% vs. 13.0%, P=0.04).CONCLUSION: Laparoscopic D3 lymphadenectomy along the left side of SMA for right colon cancer is feasible but had a higher rate of post-operative complications.
