ABSTRACT

Background/Aim. An exacerbated reaction to peritoneal infection and attendant surgical procedures is characterized by an intense hyperinflammatory state, the magnitude of which is proportional to the severity of tissue injury. Laparoscopy generates lower levels of tissue damage compared with open surgery and should induce less pronounced immune responses. The aim of this study was to determine whether laparoscopy assisted by helium rather than carbon dioxide pneumoperitoneum would induce an attenuated inflammatory state in septic animals. Materials and Methods. Thirty-two Wistar rats were divided randomly into four equal groups, two of which were submitted to carbon dioxide or helium pneumoperitoneum-assisted laparoscopic cecal ligation and puncture (CLP) induced sepsis and subsequent abdominal lavage. Two control groups were submitted to identical laparoscopic procedures with carbon dioxide or helium as insufflator gas but without CLP. After 24 hours, serum levels of tumor necrosis factor alpha (TNF-α), interleukins 1 and 6 (IL-1 and IL-6, respectively), and cortisol were determined. RESULTS: Mean concentrations of I L-1 and IL-6 in the groups of septic animals submitted to laparoscopy with carbon dioxide or helium pneumoperitoneum were not significantly different but were significantly higher than those of their respective non-CLP controls. In contrast, the levels of TNF-α), interleukins 1 and 6 (IL-1 and IL-6, respectively), and cortisol were determined. CONCLUSIONS: Laparoscopy with helium insufflation was similar to carbon dioxide in relation to the inflammatory response since levels of the proinflammatory TNF-α, IL-1, and IL-6 and of the anti-inflammatory cortisol were comparable for both gases.α), interleukins 1 and 6 (IL-1 and IL-6, respectively), and cortisol were determined.
