Change and significance of perioperative cytokine levels in children undergoing laparoscopy / 中国组织工程研究

ABSTRACT

BACKGROUND:The laparoscopy is superior to open surgery for being less invasive, inducing mild stress reaction and allowing quick recovery after operation, however the effects of laparoscopy on perioperative serum cytokine levels are controversial, and only a few studies discuss these effects among pediatric patients.OBJECTIVE: To compare the changes in perioperative cytokine levels and their clinical significance in pediatric patients undergoing laparoscopy and open surgery.DESrGN Non-randomized concurrent controlled observation.SETTTNG Department of Urology in Xijing Hospital of the Fourth Military Medical University of Chinese PLA.PARTICT PANTS From May 2004 to December 2006, 135 pediatric patients for elective operation were recruited from Department of Urology in Xijing Hospital of the Fourth Military Medical University of Chinese PLA. Sixty-five patients were scheduled for laparoscopic surgery while the remaining 70 patients for open surgery.METHODS: Serum levels of interleukin-1 beta (IL-1β), IL-6, IL-10 and tumor necrosis factor-alpha (TNF-α) were measured at 24 hours before operation, and 3, 24, 48 hours after operation respectively. Duration of hospitalization time of all the children was also recorded.MAIN OUTCOME MEASURES: Levels of IL-1β, IL-6, IL-10 and TNF-α of all the patients were measured 24 hours preoperatively, and 3, 24, 48 hours postoperatively.RESULTS: All the 135 cases were included for statistical analysis. ①There were no significant perioperative changes in cytokine levels after laparoscopic surgery (P ＞ 0.05). In the open surgery group, IL-1β and IL-6 levels increased significantly at 3 and 24 hours after operation (P ＜ 0.05), and normalized within 48 hours postoperatively. No significant perioperative differences were found in IL-10 and TNF-α levels (P ＞ 0.05). The levels of IL-1β and IL-6 were significantly higher in the open surgery group than in the laparoscopic surgery group (P ＜ 0.05). ②Duration of hospitalization was shorter in the laparoscopic surgery group than in the open surgery group [(3.5±1.0), (7.5+1.5) days, P＜ 0.05].CONCLUSTON Pediatric patients undergoing laparoscopic surgery had less perioperative changes in cytokine levels and quicker recovery.
