Comparison of efficacy and safety of general anesthesia alone with those of combined epidural/general anesthesia in Chinese patients with gastric cancer undergoing laparoscopy-assisted tumor resection
Abstract
Purpose: To compare postoperative opioid consumption, inflammatory response, survival/clinical outcomes and safety profile of epidural combined with general anesthesia (GA) versus GA in stage 1 gastric cancer patients undergoing surgical intervention by laparoscopy.
Method: Chinese patients with early-stage gastric cancer undergoing laparoscopic-assisted tumor resection were enrolled and received either epidural combined with general anesthesia (group EA + GA) or general anesthesia only (group GA) in allocation ratio of 1:1. The following efficacy variables were assessed: 1) Pain score was measured on VAS scale; 2) post-operative consumption; 3) Quality of recovery; 4) inflammatory response; and 5) survival outcome. Safety was assessed throughout the study period.
Results: Data for 200 subjects were analyzed. Compared to GA alone, combination of EA + GA demonstrate significantly greater reduction in post-operative pain with decrease postoperative opioid consumption. Also, the combination of GA and EA inhibited inflammatory response when compared to patients who received GA only. Moreover, the combination of GA and EA did not demonstrate any clinical benefit in survival outcome, when compared to patients who received GA alone, indicating that GA + EA has no role in improving survival outcome among patients undergoing gastric cancer surgery. Additionally, EA + GA was also associated with a shorter length of hospital stay, compared to GA.
Conclusion: Overall, the results favor the use of GA + EA in Chinese patients with early-stage gastric cancer undergoing laparoscopic-assisted tumor resection. GA + EA combination improves immune response by inhibiting the inflammatory response but has no significant effect on survival outcome.
