Methods A total of 56 patients with pelvic inflammation mass were admitted into Yichang Central People's Hospital from January 2008 to January 2013. Their average age was (33±12) years old. They were divided into two groups according to different surgery types, laparoscopy group (n=32) and open surgery group (n=24). The preoperation blood sample and 2, 24, 72 h after operation blood sample were collected from every subjects. ①T-lymphocyte subsets CD3, CD4 and CD8 were detected by flow cytometry (FCM), at the same time, helper T-lymphocyte (Th)1, Th2 were also detected. ②The levels of IL-18, -10 were detected by enzyme linked immunosorbent assay (ELISA). ③ The observation items after operation including intraoperative blood loss, postoperative exhaust time, duration of temperature back to normal, duration of complete blood count back to normal and hospitalization, duration of operation, hospitalization expense, operation expense and duration of antimicrobial use. The study protocol was approved by the Ethical Review Board of Yichang Central People's Hospital. Informed consent was obtained from the every participates.
Results ① There were no significant differences on T-lymphocyte subsets CD3, CD4, CD8 between preoperation and 2, 24, 72 h after operation in laparoscopy group (t=1.83, 1.69, 1.74; P>0.05). The levels of T-lymphocyte subsets CD3, CD4, CD8 at 24, 72 h after operation were lower than those of preoperation, with significant differences (24 h after operation: t=2.38, 2.47, 2.45; P<0.05; 72 h after operation: t=2.41, 2.46, 2.56; P<0.05). The levels of T-lymphocyte subsets CD3, CD4, CD8 at 2, 24 h postoperation in open surgery were significant lower than those of laparoscopy group (2 h after operation: t=2.56, 2.61, 2.69; P<0.05; 24 h after operation: t=2.61, 2.69, 2.78; P<0.05). But there were no significant difference on CD3 at 72 h after operation between two groups (t=1.68, P>0.05). ②The levels of Th1, Th1/Th2 decreased and Th2 increased at 2 h after operation, and there were significant differences of Th1, Th2 and Th1/Th2 at 2 h after operation between two groups (laparoscopy group: t=2.23, 7.35, 7.15; P<0.05; open surgery group: t=9.45; 7.18, 8.56; P<0.01). And the levels of Th1, Th2 and Th1/Th2 of laparoscopy group back to normal at 24 h after operation, there were no significant differences on the levels of Th1, Th2 and Th1/Th2 in laparoscopy group between preoperation and 24 h after operation (t=1.82, 1.38, 1.72; P>0.05). ③Compared with preoperation, the levels of IL-18 decreased and IL-10 increased at 2 h after operation in both two groups (laparoscopy group: t=6.98, 8.87; P<0.01; open surgery group: t=10.17, 7.18; P<0.01). The levels of IL-18, -10 back to normal at 24 h after operation, and there were significant differences on IL-18, -10 between preoperation and 24 h after operation in laparoscopy group (t=1.78, 1.89; P>0.05). ④There were significant differences on intraoperative blood loss, postoperative exhaust time, duration of temperature back to normal, duration of complete blood count back to normal and hospitalization between two groups (t=6.34, 12.38, 15.32, 2.37, 7.15; P<0.05). There were no significant differences on duration of operation, hospitalization expense, operation expense and duration of antimicrobial use between two groups (t=1.37, 1.67, 1.35, 1.87; P>0.05).
