Efficacy of Estrogen Therapy in Patients With Intrauterine Adhesions: Systematic Review

Hysteroscopic adhesiolysis has become the preferred option for management of intrauterine adhesions (IUA). Use of estrogen as perioperative adjuvant therapy has been suggested for preventing recurrent adhesions. The primary objective of this article was to review the literature for evidence of the efficacy of estrogen therapy in the management of IUA. All eligible studies were identified using computerized databases (PubMed, Scopus. and Web of Science) from their earliest publication date to July 2013. Additional relevant articles were identified from citations in these publications. Twenty-six studies were identified that reported use of hormone therapy as ancillary treatment after adhesiolysis. Of these studies, 19 used at least one of the following methods: intrauterine device, Foley catheter, hyaluronic acid gel, or amnion graft, in addition to hormone therapy as ancillary treatment. In 7 studies, hormone therapy was used as a single ancillary treatment. In 2 studies, no adjunctive therapy was used after adhesiolysis. Meta-analysis could not be performed because of the differences in treatment methods in these articles. There was a wide range of reported menstrual and fertility outcomes. Better menstrual and fertility outcomes were associated with use of estrogen in combination with other methods of ancillary treatment. At present, hormone therapy, in particular estrogen therapy, is beneficial in patients with IUA, regardless of stage of adhesions. However, estrogen therapy needs to be combined with ancillary treatment to obtain maximal outcomes, in particular in patients with moderate to severe IUA. (C) 2014 AAGL. All rights reserved.
