A systematic review of amniopatch

ABSTRACT

The objective of this review is to evaluate the safety and effectiveness of the amniopatch procedure for the treatment ofpreterm premature rupture of the membranes. The searches were conducted via electronic databases including Ovid-MEDLINE, Ovid-Embase, the Cochrane Library, and eight Korean databases. In the study design, in addition to randomized controlled trials, case report studies in which patients underwent the amniopatch procedure were included. Two reviewers independently selected data in standardized form and assessed the methodological quality. Quality evaluation was performed by the SIGN (Scottish Intercollegiate Guideline Network) method. A total of 11 studies (2 cohort studies, 1 case series, and 8 case reports) were included. There were no serious maternal or fetal complications. It was reported that there were lower rates of maternal chorioamnionitis after the amniopatch relative to conservative treatment (control). The mean gestational age at delivery was 27.7 weeks (a total of 70 cases in 10 studies; spontaneous group, 27.6 weeks; iatrogenic group, 27.8 weeks). The amniopatch was successful in 46.6% of cases (33/71 cases in 11 studies). The overall neonatal survival rate was 55.3% (52/94 cases in 11 studies). Neonatal morbidity was 23.4% (11/47 cases in 7 studies). Although this systematic review, did not find clear evidence of the safety and effectiveness, the amniopatch procedure is a viable treatment option to prolong a pregnancy with previable premature rupture of membranes.
