Pregnancy subsequent to postpartum Filshie clip sterilisation has occurred in 8 out of 789 patients operated on at Paarl Hospital since early 1983. As most pregnancies after sterilisation occur within 2 years, more failures can be expected. The use of this method has thus been discontinued.
自1983年初以来，在帕尔医院接受手术的789名患者中，有8名在产后使用菲氏夹绝育术后怀孕。由于大多数绝育术后怀孕发生在2年内，预计会有更多失败案例。因此，这种方法已不再使用。
