Abstract
Background & aims: We investigated the efficacy of
electroacupuncture in reducing the duration of postoperative ileus and hospital
stay after laparoscopic surgery for colorectal cancer.
Methods We performed a prospective study of 165 patients undergoing elective
laparoscopic surgery for colonic and upper rectal cancer, enrolled from October
2008 to October 2010. Patients were assigned randomly to groups that received
electroacupuncture (n = 55) or sham acupuncture (n = 55), once daily from
postoperative days 1–4, or no acupuncture (n = 55). The acupoints Zusanli,
Sanyinjiao, Hegu, and Zhigou were used. The primary outcome was time to
defecation. Secondary outcomes included postoperative analgesic requirement,
time to ambulation, and length of hospital stay.
Results: Patients who received electroacupuncture had a shorter time to
defecation than patients who received no acupuncture (85.9 ± 36.1 vs 122.1 ±
53.5 h; P
< .001) and length of hospital stay (6.5 ± 2.2 vs 8.5 ± 4.8 days; P = .007).
Patients who received electroacupuncture also had a shorter time to defecation
than patients who received sham acupuncture (85.9 ± 36.1 vs 107.5 ± 46.2 h; P = .007).
Electroacupuncture was more effective than no or sham acupuncture in reducing
postoperative analgesic requirement and time to ambulation. In multiple linear
regression analysis, an absence of complications and electroacupuncture were
associated with a shorter duration of postoperative ileus and hospital stay
after the surgery.
Conclusions: In a clinical trial, electroacupuncture
reduced the duration of postoperative ileus, time to ambulation, and postoperative
analgesic requirement, compared with no or sham acupuncture, after laparoscopic
surgery for colorectal cancer.
