Objective To investigate the clinical effects of dual therapy and triple therapy on sequelae of pelvic inflammatory disease（ SPID） of cold-damp stagnation type. Methods 120 patients who met the diagnostic criteria of SPID of cold-damp stagnation type were randomly divided into 2 groups. Two groups were respectively given dual therapy（ oral taking and enema of Chinese herbal medicines）and triple therapy（ oral taking and enema of Chinese herbal medicines plus infrared light therapy）. The changes of symptoms and signs,the clinical effects and safety index of both groups were observed and local sign scores and TCM syndrome scores were evaluated before and after 2 months of treatment. Results The total improvement rate of triple therapy group was 68. 33%, TCM syndrome improvement rate was 75. 00%, the local sign improvement rate was 66. 67%; while that of dual therapy group was 36. 67%,46. 67%,25. 00% respectively. The differences were statistically significant between the two groups（ P < 0. 05）. The sign score of both groups were obviously reduced after treatment,but the triple group was lower than the dual group,and the differences the two groups were statistically significant between（ P < 0. 05）. Conclusion The triple therapy has satisfactory effect on SPID of cold-damp stagnation type in improving the symptoms,local signs and can more obviously increase the clinical recovery rate which shows more positive effects than the dual therapy.
