ObjectiveTo observe the efficacy of administration of Daodi Tongguan decoction combined with colonic dialysis after laparoscopy for tubal obstructive infertility. MethodsA total of 210 patients with tubal obstructive infertility were randomly divided into 3 groups, with 70 cases in each group. Group A underwent laparoscopy,colonic dialysis and retention enema with Daodi Tongguan decoction. Group B underwent laparoscopy and retention enema with Daodi Tongguan decoction. Group C only underwent laparoscopic repair and plastic surgery of oviducts.The pregnancy rate, tubal patency rate, efficacy and adverse reaction were compared among the three groups. ResultsWithin 2 years after operation, the intrauterine pregnancy rate of group A ［60.00%（42/70）］ was higher than that of group B［38.57%（27/70）］ or group C ［27.14%（19/70）］(P＜0.05), but there was no significant difference in the rate between group B and group C (P＞0.05). After 18 months of operation, the total effective rate of group A(92.86%) or group B (82.86%) was higher than that of group C (55.71%), but there was no significant difference between group A and group B (P＞0.05). After six months of operation, tubal patency rate of the patients without pregnancy decreased in the order of group A, group B and group C ［67.11% (51/76), 43.56% (44/101) and 32.14% (36/112) respectively, P＜0.05)］. ConclusionAdministration of Daodi Tongguan decoction combined with colonic dialysis after laparoscopy can achieve a synergistic effect and stable short-term efficacy, is a safe and effective therapy for tubal obstructive infertility, and is worthy of clinical promotion and application.
