Comparison of temperature variations during laparoscopic and open anterior resections and abdomino-perineal resections

Objective: To compare the incidence of hypothermia during open and laparoscopic colorectal surgeries.

 

Material and methods: A retrospective analysis of temperature variations of laparoscopic anterior resection and abdomino-perineal resections performed from January 2014 to April 2016 in the Professorial surgical unit at Teaching Hospital Peradeniya, Sri Lanka was evaluated. This was compared with that of open resections.

 

Results: Thirty four patients were operated, twenty four patients being performed laparoscopically. The main temperature drop occurred soon after induction of anaesthesia, measured 15minutes after induction. The mean drop in laparoscopic group is 1.39 and 1.6 in open group. The drop in open group is higher which was statistically significant with a p value of 0.001. The fluctuations each hour subsequently were less and temperature gains were noted in some hours in both groups which. The total drop at end of procedure was 1.04 in laparoscopy group and 2.19 in open group. The difference was statistically significant with a p value of 0.05.

 

Conclusions: The temperature drop in open surgery group is higher than laparoscopic surgery group performed for carcinoma of rectum.
