Abstract
Introduction
The aim of the present study was to investigate the gas-dependent effects of pneumoperitoneum on wound healing distant from the abdomen.
Materials and methods
Dorsal skin incisions were performed in 54 male Sprague–Dawley rats. A CO2 or a helium pneumoperitoneum of 3 mmHg was maintained before, with an overall duration of 30 min (each n = 18). Rats in the control group received laparotomy only (n = 18). Animals were killed after 5 and 10 days. The infiltration of macrophages (CD 68), expression of matrix metalloproteinase 13 (MMP-13) and collagen I/III ratios were analysed in the dorsal skin wounds.
Results
Both after 5 and 10 days, infiltration of macrophages and expression of MMP-13 were greatest after helium pneumoperitoneum. After 5 days, collagen I/III ratio was significantly increased in the helium group. After 10 days, collagen I/III ratio was lowest in the CO2 group.
Conclusion
Our results suggest beneficial effects on systemic wound healing for helium pneumoperitoneum as compared to CO2.
