Effect of early second-look hysteroscopy on reproductive outcomes after hysteroscopic adhesiolysis in patients with intrauterine adhesion, a retrospective study in China

Abstract

ObjectiveThe aim of this study was to assess the effect of early second-look hysteroscopy after hysteroscopic adhesiolysis for intrauterine adhesions (IUAs) on the pregnancy rate (PR) and live birth rate (LBR). Study designIt is a retrospective, observational study of 151 women were referred to our institution from January 2010 to January 2016. Operative hysteroscopy for treatment of IUAs and office hysteroscopic follow-up to assess IUAs. We investigated demographic characteristics, menstrual pattern, previous intrauterine surgery, reproductive history, ovarian preservation assessment, tubal patency examination, husband's semen test, obstetric parameters, and surgical variables to evaluate the effect of early second-look hysteroscopy after hysteroscopic adhesiolysis on the PR and LBR. ResultsOf 151 women treated for IUAs, the general PR was 71.5% and LBR was 53.0%. The PR and LBR were higher in the earlier second-look group (compared with second hysteroscopy later than 2 months group) and the group which received less than three times adhesiolysis (p < 0.05). The PR was higher in the amenorrhea group (compared with normal menses group) and recurrent miscarriage group (compared with infertility group) (p < 0.05). Logistic regression showed that the second-look time interval, times of operation to relieve adhesion, and pregnancy history were associated with the PR, while age and the second-look time interval were associated with the LBR. ConclusionsEarly second-look hysteroscopic examinations within 2 months may increase the cumulative PR and LBR.
