Key Takeaway
Consider Chinese medicine external therapies as potential adjunctive options for IBS-D, noting low confidence in some estimates.

This systematic review and network meta-analysis evaluates the comparative efficacy of various Chinese medicine external therapies (CMETs) for patients with diarrhea-predominant irritable bowel syndrome (IBS-D). The scope includes moxibustion, tuina, electroacupuncture (EA), acupoint application combined with Western medicine (WM), and transcutaneous electrical acustimulation (TEA) compared against WM and placebo.

The analysis found that moxibustion ranked highest for the clinical total effective rate (TER) with a P-score of 0.8600, while tuina ranked second highest with a P-score of 0.7130. For symptom reduction measured by IBS-SSS, electroacupuncture (EA) demonstrated superior efficacy (P-score = 0.8854). EA also showed superior efficacy for abdominal pain relief (P-score = 0.8591). Regarding quality of life, acupoint application combined with WM was most effective (P-score = 1.0000).

A significant limitation noted is that the CINeMA assessment indicated low or very low confidence in several estimates, and formal sensitivity analyses excluding high-risk studies were not feasible for all outcomes. Clinicians should interpret these rankings cautiously due to the limited certainty of evidence. These therapies may offer viable adjunctive or complementary options for managing IBS-D symptoms.

How this fits prior evidence

This finding extends prior evidence regarding acupuncture's role in irritable bowel syndrome by evaluating specific Chinese medicine external therapies (CMETs) as potential management tools. While previous evidence noted that acupuncture modulates the microbiota-gut-brain axis to remodel microbial structure, this meta-analysis provides a comparative ranking of various modalities including moxibustion and electroacupuncture for symptom relief and quality of life in IBS-D patients.

Living with diarrhea-predominant irritable bowel syndrome (IBS-D) can be exhausting. It often involves persistent abdominal pain and digestive issues that impact daily life. A recent review looked at how different Chinese medicine external therapies, such as moxibustion and electroacupuncture, compare to standard Western medicine and placebos.

The study found that moxibustion ranked highest for overall effectiveness in clinical rates, while tuina massage followed closely. For specific symptoms like abdominal pain and general severity scores, electroacupuncture showed the strongest results compared to other methods. Additionally, combining acupoint application with Western medicine was found to be most effective for improving a patient's quality of life.

While these findings offer promising options for people seeking complementary treatments, it is important to note that the evidence is not yet definitive. The researchers noted low confidence in several estimates, meaning more high-quality studies are needed to confirm these results. If you are looking for new ways to manage your symptoms, talk to your doctor about which of these therapies might be a safe addition to your current care plan.

Specific Chinese medicine techniques like moxibustion and electroacupuncture may help manage IBS-D symptoms.

Common questions

What specific treatments were found to help with IBS-D?

The study looked at several Chinese medicine external therapies. Moxibustion ranked highest for overall clinical effectiveness, while tuina massage ranked second. For reducing abdominal pain and improving general severity scores, electroacupuncture was found to be more effective than other methods.

Can these treatments improve my quality of life?

The research found that combining acupoint application with Western medicine was the most effective method for improving a patient's quality of life. However, because some results had low confidence levels, you should discuss these options with your doctor.

Are there any safety concerns with these therapies?

The study noted that transcutaneous electrical acustimulation (TEA) and placebo treatments had the lowest risk of adverse events. Because some evidence is still limited, consult a healthcare professional to determine which treatment is safest for your specific needs.

BackgroundDiarrhea-predominant irritable bowel syndrome (IBS-D) is a chronic functional gastrointestinal disorder that significantly impairs patients’ quality of life. While various Chinese medicine external therapies (CMETs) have been widely utilized, their relative superiority and safety remain poorly defined. This study aims to evaluate and rank the comparative efficacy and safety of different CMETs for IBS-D.MethodsWe systematically searched PubMed, Embase, The Cochrane Library, and CNKI from inception to March 2026 for randomized controlled trials (RCTs) evaluating CMETs for IBS-D. The primary outcomes were clinical total effective rate (TER) and the IBS Severity Scoring System (IBS-SSS). Secondary outcomes included IBS-Quality of Life (IBS-QOL), abdominal pain scores, and adverse events (AE). A frequentist network meta-analysis (NMA) was performed using the netmeta package in R software. Interventions were ranked using P-scores. Global and local inconsistency were assessed via Q-statistics and the node-splitting method.ResultsTwenty-two RCTs involving 11 distinct interventions were included. For the clinical total effective rate (TER), moxibustion (P-score = 0.8600) and tuina (P-score = 0.7130) emerged as the top-ranked interventions compared with Western medicine (WM) and placebo. Regarding symptom reduction (IBS-SSS) and abdominal pain relief, electroacupuncture (EA) (P-scores = 0.8854 and 0.8591, respectively) demonstrated superior efficacy over other modalities. Acupoint application combined with WM was found to be the most effective for improving quality of life (P-score = 1.0000). Safety analysis indicated that transcutaneous electrical acustimulation (TEA) (P-score = 0.8108) and placebo had the lowest risk of adverse events. Node-splitting analysis did not indicate statistically significant inconsistency; however, the findings should be interpreted cautiously because formal sensitivity analyses excluding high-risk studies were not feasible for all outcomes.ConclusionChinese medicine external therapies may provide beneficial adjunctive or complementary options for patients with IBS-D. Moxibustion ranked highest for study-defined TER, whereas EA ranked highest for IBS-SSS and abdominal pain reduction. However, CINeMA assessment indicated low or very low confidence in several estimates; therefore, these rankings should be interpreted cautiously.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=1324349, identifier CRD420261324349.
