Efficacy of multimodal analgesia based on the concept of enhanced recovery after surgery in laparoscopic radical gastrectomy for gastric cancer.

OBJECTIVE

To explore the effect of multimodal analgesia based on the concept of enhanced recovery after surgery (ERAS) in patients undergoing laparoscopic radical gastrectomy (LRG) for gastric cancer (GC).

METHODS

Clinical data of 128 patients undergoing LRG for GC, admitted to Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from March 2021 to March 2022, were retrospectively analyzed. Among them, 66 patients received a multimodal analgesic management based on ERAS (ERAS group), and 62 patients were treated with conventional mode of analgesia (control group). Pain levels, rehabilitation status, as well as inflammatory factors and stress response indicators before and after surgery were compared between the two groups.

RESULTS

There was no significant difference in baseline data between the two groups (>0.05). The postoperative pain and recovery in the ERAS group were better than those in the control group (<0.05). After the surgery, serum levels of tumor necrosis factor-alpha (TNF-α), Interleukin 6 (IL-6), and C-reactive protein (CRP) in both groups increased compared to before the surgery, but were significantly lower in the ERAS group compared to the control group (<0.05). After the surgery, serum malondialdehyde (MDA) and xanthine oxidase (XOD) levels in both groups increased, while superoxide dismutase (SOD) levels decreased compared to preoperative levels. The observed postoperative levels of serum MDA and XOD were significantly lower in the ERAS group, while the postoperative SOD levels were higher compared to the control group (<0.05).

CONCLUSIONS

Patients undergoing LRG for GC can benefit from a multimodal pain management plan based on ERAS to reduce postoperative pain, alleviate inflammation, stress responses, and shorten the postoperative recovery process.
