Operative stress response, energy metabolism, and visceral proteins after laparoscopic-assisted resection of rectal carcinoma / 中国微创外科杂志

ABSTRACT

Objective To compare the differences between laparoscopic-assisted and open resection of rectal carcinoma in respect of peri-operative levels of C-reactive protein (CRP), rest energy expenditure (REE), and visceral proteins. Methods According to patients' choice of operation, either laparoscopic-assisted (n=20, Laparoscopic Group) or open (n=25, Open Group) resection of rectal carcinoma was performed. The levels of CRP and visceral proteins-including albumin (ALB), prealbumin (PRE), transferrin (TRF), and retinal-binding protein (RbP)-were assayed preoperatively and on the 1st, 2nd, and 3rd day postoperatively. The levels of REE were also measured by indirect calorimetry in the morning. Results Compared with the preoperative period, the CRP levels in both groups were significantly increased on the 1st, 2nd, and 3rd day (P0.05). The levels of PRE in the Laparoscopic Group were significantly higher than those in the Open Group on the 2nd postoperative day (P
