The aim of this study was to establish the trend of obstetric anal sphincter injuries (OASIS) in Wales. A retrospective search of Patient Episode Database for Wales (PEDW) data was carried out. Data were available for 11 years from 1999 to 2009. The incidence of OASIS steadily increased from 1.81% in 1991 to 5.62% in 2009 (χ(2) for trend p < 0.001), which is more than a three-fold increase. This was observed alongside a significant increase in resort to episiotomy (χ(2), p < 0.001) and forceps delivery (χ(2), p < 0.001), drop in the use of ventouse delivery (χ(2), p < 0.001) as well as increase in caesarean delivery (χ(2), p < 0.001) over the same period. This showed the incidence of OASIS in Wales to have risen significantly and steadily over the period 1999-2009. This necessitates a look to identify and deal with the cause(s) of this rise and monitor its future course.
本研究旨在确定威尔士产科肛门括约肌损伤（OASIS）的趋势。对威尔士患者事件数据库（PEDW）的数据进行了回顾性检索。可获取1999年至2009年11年的数据。OASIS的发生率从1991年的1.81%稳步上升至2009年的5.62%（趋势χ(2)检验，p < 0.001），增长超过三倍。同期，会阴切开术的使用显著增加（χ(2)检验，p < 0.001）、产钳助产显著增加（χ(2)检验，p < 0.001）、胎头吸引助产的使用减少（χ(2)检验，p < 0.001）以及剖宫产显著增加（χ(2)检验，p < 0.001）。这表明在1999 - 2009年期间，威尔士OASIS的发生率显著且稳步上升。这需要找出并处理导致这种上升的原因，并监测其未来发展趋势。
