Abstract:
Objective:To compare the results of lymph node dissection boundaries along the right or left sides of SMA in laparoscopic radical resection for right colon cancer.Methods:One hundred and two patients with advanced right colon cancer were selected for retrospective analysis, the patients were divided into study group (48 cases) and control group (54 cases) according to the extent of lymph node resection. The medial boundary of lymph node dissection in the study group was on the left side of SMA, and the control group was on the right side of SMA. The operation duration, hospital stays, CRP(postoperative day 1), the number of dissected lymph nodes and the complications were compared.Results:The operation duration of the study group was longer than that of the control group[(169±24)min vs.(138±28)min, t=4.827, P<0.05], but there was no statistically significant difference in hospital stays[(10.5±1.7)d vs.(9.7±2.0)d, t=1.172, P>0.05], CRP(postoperative day 1) [(110±44)mg/L vs.(100±39)mg/L, t=1.287, P>0.05], incidence of postoperative complication(12 cases vs. 9 cases, P>0.05) between the two groups.The number of lymph nodes removed in the study group was more than that in the control group[(23.8±8.2) vs.(19.7±6.8), t=2.191, P<0.05], though the number of positive lymph nodes removed in the two groups was not significantly different[(2.2±4.9) vs.(1.4±2.8), t=0.863, P>0.05]. Conclusions:Laparoscopic radical resection for right colon cancer along the left sides of SMA removed more lymph nodes without significant increase of the surgical complications.
