Manual Acupuncture for Postoperative Pain and Recovery after Abdominal Surgeries: A Systematic Review.

If you or a loved one is facing abdominal surgery, you may be wondering about ways to manage pain and speed up recovery beyond standard medications. A new research review published in the Journal of Integrative and Complementary Medicine looked at whether manual acupuncture — the traditional practice of inserting fine needles at specific points on the body — could help patients recover more comfortably after abdominal operations.

Researchers searched multiple major medical databases and found eight relevant clinical trials involving 551 patients who had undergone various abdominal surgeries. They looked at several recovery measures, including post-surgical pain levels, how much pain medication patients needed, nausea, the return of normal digestive function, and how long patients stayed in the hospital.

The results were encouraging. Across the studies reviewed, patients who received acupuncture tended to report less pain after surgery, needed fewer pain-relieving medications, experienced less nausea, and showed faster recovery of normal gut function — an important milestone after abdominal procedures. One study also found that acupuncture was linked to shorter hospital stays.

However, the researchers were careful to note that the overall quality of the evidence has important limitations. The studies varied widely in their methods, and not all trials clearly reported safety information or followed standardized protocols. This made it impossible to combine the results into a single definitive conclusion. The authors stress that larger, better-designed studies are needed before acupuncture can be formally recommended as a standard part of surgical care.

For now, these findings suggest acupuncture holds real promise as a complementary tool in surgical recovery — potentially reducing reliance on opioid pain medications and supporting the body's natural healing process.

If you are considering acupuncture before or after surgery, speak with your surgical team and seek care from a licensed, qualified acupuncture practitioner.

This systematic review (PROSPERO: CRD42022311718) evaluated manual acupuncture as an adjunct intervention for postoperative pain management and functional recovery following abdominal surgery. Eight RCTs met inclusion criteria from an initial pool of 700 records (PubMed, Cochrane, Web of Science, Google Scholar; search through May 2023), encompassing 551 patients across trials ranging from 16 to 200 participants. Primary outcomes assessed included postoperative pain scores, analgesic consumption, nausea incidence, gastrointestinal recovery indices, and length of hospital stay. Cochrane RoB 2 assessment revealed high risk of bias across studies due to heterogeneous experimental designs and absent or unpublished protocols, precluding meta-analysis. Despite these limitations, consistent directional trends favored acupuncture: reduced pain scores, decreased analgesic requirements, lower nausea incidence, accelerated GI motility restoration, and in one trial, shortened hospitalization. Adverse event reporting was adequate in only two trials. Clinically, findings support exploring manual acupuncture as a perioperative adjunct, though standardized protocols and adequately powered trials are essential before definitive recommendations can be established.
