Perioperative hypothermia increases the morbidity of surgery. However, the true incidence of hypothermia during prolonged laparoscopic surgery is still unknown. To investigate this issue, we compared the temperature change between patients undergoing open and laparoscopic colorectal surgery. ⋯ The incidence of hypothermia in open and laparoscopic colorectal surgery is similar. Forced-air warming devices are of value in prolonged laparoscopic surgery. A gender difference in the response to a hypothermic situation has not been previously reported. This finding warrants further investigation.

Whereas there are case reports of laparoscopy in patients with ventriculoperitoneal shunts, there are no studies assessing the potential failure of shunt valves with the increased intra-abdominal pressure of laparoscopy. This study aims to assess this factor. ⋯ There appears to be minimal risk of retrograde failure of the valve system in the ventriculoperitoneal shunt tested. However, tests on different types of ventriculoperitoneal shunts would be needed to confirm these results if laparoscopy is to be considered safe in patients with ventriculoperitoneal shunts in situ.
