Background/Aims:
Peritoneal immune response as well as systemic response was objectively evaluated in laparoscopy-assisted distal gastrectomy (LADG) compared to open distal gastrectomy (ODG).
Methodology:
A total of 42 patients with gastric cancer were enrolled, with 23 undergoing LADG and 19 ODG. We evaluated the levels of IL-6 in peritoneal drain fluid, serum C-reactive protein (CRP), white blood cells (WBC), and the postoperative presence of systemic inflammatory response syndrome (SIRS).
Results:
The serum CRP level was significantly higher in the ODG group than in the LADG group (p=0.007) on postoperative day (POD) 1. WBC counts showed no statistically significant difference between the two groups (p=0.105). The rate of cases exhibiting SIRS was significantly higher in the ODG group than in the LADG group (p<0.001). The IL-6 level of drain fluid was significantly higher in the ODG group than the LADG group (p<0.01) on POD1. Although weak correlation between IL-6 on POD1 and blood loss (R=0.38, p=0.0154) was observed, no significant correlation between IL-6 and operation time was noted.
Conclusions:
LADG seems to be a lesser traumatic approach for the treatment of gastric cancer.
