A complication of Plastibell circumcision requiring hospital admission is described. This occurred in three siblings of different ages who were circumcised at the same time by a non-medical religious operator. The complication was caused by proximal dislocation of the Plastibell ring, which failed to fall off at the usual time. In one case a general anaesthetic was required to remove the ring. Careful observation, by informed parents, after such a procedure will allow early intervention which should prevent such an occurrence.
