Abstract:
Objective To compare the effects and significance of laparoscopic and open D2 gastrectomy on the expression of interleukin (IL)-6 and IL-10.
Methods The clinical data of 146 patients with gastric cancer who were admitted to the Southwest Hospital from November 2010 to October 2011 were prospectively analyzed. All the patients were randomly divided into the laparoscopic group (75 patients) and open group (71 patients) according to the sealed envelope method. Laparoscopic or open D2 gastrectomy were performed according to the 14th edition of gastric cancer treatment guidelines of Japan Gastric Cancer Association. Peritoneal lavage fluid was collected at the beginning and the end of operation, and the concentrations of IL-6 and IL-10 in the peritoneal lavage fluid were detected by enzyme linked immunosorbent assay. The measurement data were analyzed using the t test, and the count data were analyzed using the chi square test.
Results The preoperative concentrations of IL-6 in the laparoscopic group and the open group were (34±13)μg/L and (35±12)μg/L, respectively, with nosignificantdifference between the 2 groups (t=-5.110, P〖WTBZ〗>0.05). The postoperative concentrations of IL-6 in the laparoscopic group and the open group were (4015±1592)μg/L and (6724±2112)μg/L, respectively. The postoperative concentration of IL-6 in the laparoscopic group was significantly lower than that of the open group (t=-8.367, P<0.05), and the postoperative concentrations of IL-6 were significantly higher than those before operation in the laparoscopic group and open group (t=-59.065,-87.123, P<0.05). The preoperative concentrations of IL-10 in the laparoscopic group and the open group were (43±9)μg/L and (42±10)μg/L, respectively, with no significant difference between the 2 groups(t=1.190, P>0.05).The postoperative concentrations of IL-10 in the laparoscopic group and the open group were (92±32)μg/L and (62±23) μg /L, respectively. The postoperative concentration of IL-10 was significantly higher than that of the open group (t=6.408, P<0.05), and the postoperative concentrations of IL-10 were significantly higher than those before operation in the laparoscopic group and the open group (t=-12.680,-6.802, P<0.05).
Conclusion Peritoneal inflammatory reaction is relatively lighter after laparoscopic D2 gastrectomy when compared with open D2 gastrectomy, which might prevent the peritoneal metastasis of gastric cancer mediated by IL-6.
