Value of transvaginal three-dimensional ultrasound in evaluating the curative effect of Yangmo decoction in the treatment of uterine adhesion.

Abstract

Intrauterine adhesions (IUA) is the damage of the basal layer of the endometrium caused by various reasons, resulting in adhesion of the uterine muscle walls to each other, which is manifested as clinical symptoms such as spanomenorrhea, amenorrhea, and infertility. Hysteroscopic adhesiolysis (HA) is the main treatment, for patients with moderate or severe adhesion or angular adhesion, the incidence of postoperative adhesion is high. Traditional Chinese medicine "Yangmo decoction" can promote endometrial growth. Three-dimensional transvaginal ultrasonography (3D-TVUS) can judge IUA and evaluate uterine receptivity through three-dimensional imaging. This study aims to investigate the value of 3D-TVUS in judging the efficacy of Yangmo decoction in the treatment of intrauterine adhesions. The clinical data of patients who underwent HA at two different centers in department of Gynecology of Third Xiangya Hospital of Central South University and Changsha Jiangwan Hospital from January 2021 to August 2021 were retrospectively collected. A total of 275 eligible patients were included. According to the postoperative management measures, the selected patients were divided into two groups. Yangmo decoction group (n=138): the use of Yangmo decoction and uterine-shaped silicon stent post HA; Hormone group (n=137): the use of estrogen, progesterone and uterine-shaped silicon stent post HA. The preoperative general data, preoperative and postoperative 3D-TVUS parameters of the two groups were analyzed. The endometrial thickness of Yangmo decoction group was thicker than that of hormone group (P<0.001), the intercornual distance was wider (P=0.016), the endometrial echo was more homogeneous (P=0.018), the percentage of bilaterally visible tubal opening was higher (P<0.001), the endometrial morphology was better (P=0.012), and endometrial blood flow, endometrial motility and uterine motion were better in Yangmo decoction group than that in the hormone group (all P<0.001). The endometrial thickness, echo, blood flow, and peristalsis, the number of visible tubal opening, uterine motion, and the intercornual distance obtained by 3D-TVUS examination are important factors to evaluate the prognosis of postoperative drug treatment for IUA. 3D-TVUS is of great significance in evaluating the efficacy of Yangmo decoction in the treatment of IUA.
