Assessment of physical stress during the perioperative period of endoscopic submucosal dissection

Table 1 Perioperative changes in resting energy expenditure, resting energy expenditure/basal energy expenditure, and stress factors by endoscopic submucosal dissection

	ESD preoperative state	ESD postoperative state
Gastric cancer
REE (kcal)	1170.3 ± 209.0	1238.4 ± 235.5c
REE/BEE	0.96 ± 0.11	1.03 ± 0.14c
Stress factor		1.07
Colorectal cancer
REE (kcal)	1107.0 ± 204.4	1139.9 ± 185.2c
REE/BEE	0.96 ± 0.12	1.00 ± 0.13c
Stress factor		1.06

^cP < 0.001 vs endoscopic submucosal dissection (ESD) preoperative state.

Data are presented as mean ± SD. The stress factor on ESD in the postoperative state was computed by setting the stress factor on the day of ESD to be 1.0. ESD: Endoscopic submucosal dissection; REE: Resting energy expenditure; BEE: Basal energy expenditure.
