The use of silastic perianal rings to control rectal prolapse in the elderly has been reviewed. Forty-one patients were treated over a 6 year period by a total of 52 operations. Their mean age was 80 years and there was no operative mortality. Prolapse was adequately controlled in 71 per cent of patients, and a further three patients had no recurrence despite failure and removal of the ring. The results of this procedure are inferior to those obtained by abdominal operations for rectal prolapse, but deserve serious consideration in those elderly patients who may be unfit for laparotomy.
对使用硅橡胶肛门环控制老年人直肠脱垂的情况进行了回顾。在6年期间，共对41例患者进行了52次手术。他们的平均年龄为80岁，无手术死亡病例。71%的患者脱垂得到充分控制，另有3例患者尽管环失败并被移除，但未复发。该手术的结果不如直肠脱垂腹部手术的结果，但对于那些可能不适合剖腹手术的老年患者值得认真考虑。
