AimHaemorrhoidectomy usually causes moderate to strong postoperative pain. Chinese studies have found that acupuncture may have an analgesic effect in posthaemorrhoidectomy patients. This is the first Western study aiming assess the efficacy of acupuncture as an adjunct analgesic therapy after stapled haemorrhoidopexy.MethodIn a randomized controlled trial, 50 patients were allocated to three groups. Conventional drug therapy (oral diclofenac and metamizol, local lidocaine) served as baseline analgesia. In the control group (n = 17) only this regimen was used. In addition to baseline analgesia, 17 patients received verum acupuncture. Sham acupuncture was performed on 16 patients. Being the primary outcome measure, pain was measured twice daily using the numerical rating scale (NRS) and compared statistically by repeated-measures analysis of variance. The study was registered (DRKS00003116). Results  After verum acupuncture, pain intensity was not significantly lower when compared with conventional analgesia (primary hypothesis, P = 0.057), but was when compared to sham acupuncture (P = 0.007). In the afternoon of postoperative day 1, for example, NRS was 2.7 (SD 1.5) in the verum group, but 4.0 (1.0) in the sham group and 4.1 (1.9) under conventional analgesia. Furthermore, significantly fewer rescue analgesics were necessary if verum acupuncture was applied. Cardiovascular parameters were stable in all three groups, and no complications were recorded.ConclusionsIn posthaemorrhoidectomy patients, acupuncture appears to be an effective adjunct to conventional analgesia. Further studies are necessary to confirm these observations and to refine the acupuncture technique.© 2012 The Authors.
