Meta-analysis of the efficacy of dydrogesterone combined with estradiol valerate for the prevention of intrauterine adhesion and prognosis improvement after induced abortion
To systematically evaluate the efficacy of dydrogesterone combined with estradiol valerate for the prevention of intrauterine adhesion (IUA) and prognosis improvement after induced abortion.
METHODS
2
Retrieved from CNKI, Wanfang Data, VIP, CBM, PubMed, Embase and the Cochrane Library, randomized controlled trial (RCT) about conventional treatment combined with dydrogesterone and estradiol valerate (trial group) versus conventional treatment (control group) for the prevention of IUA in patients after induced abortion were collected from the inception to Dec. 2024. After screening the literature, extracting data and evaluating the quality of literature, meta-analysis was performed using RevMan 5.4 software.
RESULTS
2
A total of 12 RCTs were included, involving 1 109 patients. Meta-analysis showed that the postoperative incidence of IUA [RR=0.30, 95%CI (0.22, 0.41),
P
<0.000 01
]
, postoperative vaginal bleeding time [MD=-1.69, 95%CI (-2.05, -1.32),
, postoperative menstrual resumption time [MD=-6.99, 95%CI (-8.27, -5.71),
P
<0.000 01
]
, and the incidence of postoperative reduced menstrual flow [RR=0.25, 95%CI (0.12, 0.56),
P
=0.000 7
]
were significantly lower, less or shorter than control group; postoperative endometrial thickness [MD= 1.90, 95%CI (1.68, 2.13),
P
<0.000 01
]
and the rate of postoperative re-pregnancy [RR=6.26, 95%CI (1.88, 20.83),
P
=0.003
]
were significantly higher than control group.
CONCLUSIONS
2
Dydrogesterone combined with estradiol valerate may reduce the incidence of IUA after induced abortion patients, decrease postoperative vaginal bleeding volume, shorten postoperative vaginal bleeding time and postoperative menstrual resumption time, and increase postoperative endometrial thickness.
