After laparoscopic colorectal cancer surgery within an enhanced-recovery pathway, can electroacupuncture shorten postoperative ileus?

Evidence at a glance

  • Evidence label: Promising perioperative evidence; not yet routine care
  • Benefit: A multicenter sham-controlled trial found earlier first defecation and fewer cases of prolonged postoperative ileus.
  • Certainty: Moderate confidence in the measured short-term effect; replication outside the studied surgical system is needed.
  • Risk: No severe treatment-related adverse events were reported, but perioperative needling requires surgical-team coordination.

What was studied

Population and design: 249 adults were randomized at three Chinese hospitals; 248 were analyzed after laparoscopic colorectal cancer resection.

Studied regimen: Four electroacupuncture sessions after surgery versus sham electroacupuncture, alongside the same enhanced recovery protocol.

What the evidence found

Median time to first defecation was 76.4 hours with electroacupuncture versus 90.0 hours with sham. The adjusted mean difference was −8.76 hours (95% CI −15.80 to −1.73; P=.003). Prolonged postoperative ileus occurred in 10% versus 20% (risk ratio 0.51, 95% CI 0.27–0.95). Several other secondary recovery outcomes did not differ.

How to interpret it

The absolute gain was measured in hours and its practical importance will vary. The trial was conducted in China with protocolized surgery and acupuncture; it does not establish effects on complications beyond ileus, readmission, tumor control or survival.

Practical safety context

No severe acupuncture-related adverse events were reported. Needling soon after surgery should be discussed with the surgeon, especially with bleeding risk, infection, drains, altered anatomy or unstable cardiopulmonary status. It should never delay evaluation of obstruction, leak or other surgical complications.

Questions for the care team

  • Is the symptom or complication being caused by something that needs conventional treatment first?
  • Would blood counts, anticoagulants, infection risk, surgery, radiation effects or implanted devices change whether this is safe?
  • What outcome will we track, and when should we stop if it is not helping?

Funding and conflicts

Chinese public research funding was reported; detailed funder roles and author conflicts are available in the full report.
