Abstract: By present invention it has been found that hypothermia decreases adhesion formation more specifically pneumoperitoneum-enhanced adhesion formation. A cooling system has been designed to reduce the peritoneal cavity temperature during surgery, while maintaining at all times a 100% relative humidity in order to prevent desiccation, and a regulatory unit designed to condition the insufflated gas to achieve this while minimalising the necessary cooling. This is a new method for more effectively preventing adhesion though cooling while preventing desiccation. In mice it was demonstrated that factors such as environmental temperature, anaesthesia, ventilation and pneumoperitoneum can be used to influence body temperature in order to prevent adhesion formation.
