Seventeen selected patients (mean age, 74 years)--14 with rectal prolapse and 3 with persisting anal incontinence after previous operations--underwent high anal encirclement with polypropylene mesh. There was no operative mortality. Prolapse recurred in 2 (15 percent) of the 13 patients followed up for 6 months or more (mean, 3.5 years). Three (27 percent) of the 11 patients with associated anal incontinence improved functionally, as did the three operated on for persisting incontinence, but only one patient regained normal continence. No breakage, cutting out, or infection related to the mesh was observed. Because of the risk of fecal impaction encountered in three of our patients, the procedure is not advocated for severely constipated patients. Despite the somewhat disappointing results regarding restoration of continence, we find this method useful in patients with rectal prolapse who are unfit for more extensive surgery, in controlling the prolapse to an acceptable degree.
17名选定患者（平均年龄74岁）——14例直肠脱垂患者和3例先前手术后仍存在肛门失禁的患者——接受了聚丙烯网片高位肛门环扎术。无手术死亡病例。在随访6个月或更长时间（平均3.5年）的13例患者中，2例（15%）出现脱垂复发。11例伴有肛门失禁的患者中有3例（27%）功能改善，3例因持续性失禁接受手术的患者也是如此，但只有1例患者恢复了正常控便能力。未观察到与网片相关的破裂、切割或感染情况。由于我们的3例患者出现了粪便嵌塞的风险，因此不建议对严重便秘患者采用该手术。尽管在控便恢复方面结果有些令人失望，但我们发现这种方法对于不适合进行更广泛手术的直肠脱垂患者在将脱垂控制在可接受程度方面是有用的。
