PURPOSE: This study evaluated differences in stress response and immunological function following laparoscopic and conventional total mesorectal excision (TME) for rectal cancer.
METHODS: Patients with non-metastasized rectal cancer were prospectively randomized to open (n = 18) or laparoscopic (n = 22) TME. Blood samples were taken preoperatively (baseline), 2, 24, and 72 h following surgery. Systemic white blood cell and monocyte count, C-reactive protein, interleukin-6 (IL-6), interleukin-8 (IL-8), HLA-DR expression on monocytes, growth hormone, prolactin, and cortisol were measured.
RESULTS: Forty patients with a median age of 66 years (interquartile range, 60-74 years) were included. Eighteen patients (45%) were randomized to open surgery and 22 patients (55%) to laparoscopic surgery. Patient demographics in terms of gender, age, BMI, ASA classification, localization of the tumor, and type of neoadjuvant therapy were comparable for both groups. Laparoscopic surgery resulted in a significantly better short-term preservation of postoperative immune function. HLA-DR expression on monocytes was significantly higher (64% vs 50%, P = 0.014) and IL-6 level increase was significantly lower (4.6 vs 10.8, P = 0.003) 2 h after laparoscopic surgery. No differences between the open and laparoscopic technique were observed in postoperative white blood cell count, monocyte count, C-reactive protein, IL-8, growth hormone, prolactin, and cortisol levels.
CONCLUSION: Short-term postoperative immune and inflammatory functions tended to be better after laparoscopic rectal surgery. However, the differences were not consistent at all time intervals, making a definitive conclusion difficult. Better preserved inflammatory function 2 h after surgery may reflect a reduction in operative trauma when the laparoscopic technique is compared with open rectal procedures.
