Electroacupuncture promotes gastrointestinal function recovery in patients undergoing laparoscopic gastrectomy : a randomized controlled trial.

OBJECTIVES: To explore the clinical effect of electroacupuncture (EA) on promoting gastrointestinal function recovery in patients undergoing laparoscopic gastrectomy.

METHODS: One hundred and twenty patients undergoing laparoscopic gastrectomy were randomly divided into an EA group (40 cases, 1 case was eliminated), a placebo EA (PEA) group (40 cases, 1 case dropped out) and a conventional treatment group (40 cases, 1 case dropped out). The patients in the conventional treatment group received perioperative routine treatment. On the basis of routine treatment, patients in the EA group and the PEA group were given electroacupuncture or placebo electroacupuncture stimulation at 24,48 and 72 h after anesthesia recovery. Bilateral Neiguan (PC 6), Zusanli (ST 36) and Shangjuxu (ST 37) were selected, and the electrodes of SDV-Z electroacupuncture instrument were connected to Zusanli (ST 36) and Shangjuxu (ST 37) on the same side respectively. Continuous wave was selected, the frequency was 5 Hz, and the needles were retained for 30 min each time. The postoperative gastrointestinal-2 ( GI-2 ) time, the incidence of grade A/B delayed gastric emptying were compared among the three groups, and the safety of acupuncture was evaluated.

RESULTS: The GI-2 time of the EA group was significantly shorter than that of the PEA group and the conventional treatment group ( P <0.05). The incidence of grade A and grade B of delayed gastric emptying in the EA group was lower than that in the PEA group and the conventional treatment group ( P <0.05). No acupuncture-related adverse reactions occurred.

CONCLUSIONS: EA can promote the recovery of gastrointestinal function in patients undergoing laparoscopic gastrectomy, and the treatment plan is safe, which is worthy of promotion and application into the enhanced recovery surgery program.
