Introduction
Gastrointestinal dysfunction is a common complication in septic patients, contributing to adverse outcomes such as enteral nutrition intolerance, bacterial translocation, and increased mortality. While randomized controlled trials (RCTs) suggest that Traditional Chinese Medicine (TCM) external therapies may help manage this condition, the most effective therapy remains unclear. This review aims to evaluate the effectiveness of various TCM external therapies in improving gastrointestinal dysfunction in septic patients through a network meta-analysis.
Methods
We conducted a comprehensive search of eight databases for RCTs on TCM external therapies for gastrointestinal dysfunction in sepsis, published up to December 2024 and updated in June 2025. The Cochrane Risk of Bias 2.0 (RoB 2.0) tool was used to assess bias. A frequentist network meta-analysis was performed using Stata 18, calculating standardized mean difference (SMD) or weighted mean differences (WMD) for continuous outcomes, and risk ratios (RR) for binary outcomes, with 95% confidence intervals. Clinical significance was determined in conjunction with the minimal clinically important difference (MCID). Evidence quality was assessed using the Confidence in Network Meta-Analysis (CINeMA) framework.
Results
Fifty studies involving 3999 participants were included, comparing 10 TCM external therapies. Among these, 41 (82%) raised concerns, and 9 (18%) were high-risk. CINeMA ratings were mainly “low” or “very low” confidence. Compared to conventional treatment (CT), CT combined with acupoint application increased the number of bowel sounds (WMD = 1.10; 95% CI: 0.75, 1.44), exceeding the MCID. Compared to CT, CT combined with Chinese herbal enema showed more extensive benefits, including a reduction in Acute Physiology and Chronic Health Evaluation II (APACHE II) score (WMD = -4.03; 95% CI: -4.96, -3.10), an improvement in gastrointestinal dysfunction score (SMD = -0.68; 95% CI: -0.99, -0.36), and decreased inflammatory markers (white blood cell count and procalcitonin), all of which were clinically significant. Both combined therapies also significantly enhanced the clinical effective rate compared to CT.
Conclusion
CT combined with Chinese herbal enema and CT combined with acupoint application offer distinct benefits in improving gastrointestinal dysfunction in sepsis. To validate these conclusions and establish a universally recognized MCID, large-scale, high-quality, and well-designed RCTs are needed.
