Acupuncture can assist recovery following surgery for colorectal cancer (CRC). Chinese researchers included 22 studies (1,628 participants) in their analysis. The results suggested that the addition of acupuncture following CRC surgery improved recovery of gastrointestinal function. Meta-analyses found significant reductions in time to first bowel sounds, first flatus and first defecation, in both the sham-controlled and non-blinded studies. The best evidence was for interventions that included electro-acupuncture at the point Zusanli ST-36.
