BackgroundEsophagectomy is a highly invasive procedure, and recently the use of minimally invasive esophagectomy (MIE) via thoracoscopy and laparoscopy increased, since this technique possibly enhances the recovery and outcomes of the patient compared with open esophagectomy (OE). However there is little data about intraoperative changes in body temperature during OE and MIE.MethodsWe retrospectively investigated the intraoperative body temperature and the postoperative short-term outcomes of patients undergoing OE (n = 33) or MIE (n = 24). The rectal temperature was recorded at 5 time points (at the start of the surgery, 1, 3, and 5 h after the start of the surgery, and at the end of the surgery).ResultsThe average body temperature at the start was similar between the OE and MIE groups (36.5 +/- 0.4 vs. 36.6 +/- 0.5 degrees C, P = 0.497). Throughout the surgery, the temperature of the OE group increased to 37.1 +/- 0.6 degrees C, but the temperature in the MIE group decreased to 36.1 +/- 0.8 degrees C. There was no significant difference in 30-day mortality and short-term complications between the two groups.ConclusionsOur study showed that the intraoperative temperature during MIE tended to decrease compared with OE, but the short-term outcomes were comparable.
