Many operations have been described for the management of rectal prolapse. Despite an overall recurrence rate of greater than 15 percent, few reviews address how to deal with this problem. This report summarizes our experience with recurrent rectal prolapse and includes suggestions for reoperative management of failed repairs from both abdominal and perineal approaches.
Fourteen patients (3 male) ranging in age from 22 to 92 (mean, 68) years underwent operative correction of recurrent rectal prolapse. Average time from initial operation to recurrence was 14 (range, 6-60) months. Initial operations (before recurrence) were as follows: perineal proctectomy and levatorplasty (10), anal encirclement (2), Delorme's procedure (1), and anterior resection (1). Operative procedures performed for recurrence were as follows: perineal proctectomy and levatorplasty (7), sacral rectopexy (abdominal approach; 3), anterior resection with rectopexy (2), Delorme's procedure (1), and anal encirclement (1). Average length of follow-up was 50 (range, 9-115) months.
No further episodes of complete rectal prolapse were observed during this period. Preoperatively, three patients were noted to be incontinent to the extent that necessitated the use of perineal pads. The reoperative procedures failed to restore fecal continence in any of these three individuals. One patient died in the postoperative period after anal encirclement from an unrelated cause.
Surgical management of recurrent rectal prolapse can be expected to alleviate the prolapse, but not necessarily fecal incontinence. Perineal proctectomies can be safely repeated. Resectional procedures may result in an ischemic segment between two anastomoses, unless the surgeon can resect a previous anastomosis in the repeat procedure. Nonresectional procedures such as the Delorme's procedure should be strongly considered in the management of recurrent rectal prolapse if a resectional procedure was performed initially and failed.
已有多种手术方法用于治疗直肠脱垂。尽管总体复发率超过15%,但很少有综述探讨如何处理这一问题。本报告总结了我们处理复发性直肠脱垂的经验,并给出了针对经腹和经会阴入路修复失败后再次手术处理的建议。
14例患者(3例男性)接受了复发性直肠脱垂的手术矫正,年龄22至92岁(平均68岁)。从初次手术到复发的平均时间为14个月(范围6至60个月)。初次手术(复发前)情况如下:经会阴直肠切除术加提肛肌成形术(10例)、肛门环缩术(2例)、德洛姆手术(1例)和前切除术(1例)。复发后进行的手术如下:经会阴直肠切除术加提肛肌成形术(7例)、骶骨直肠固定术(经腹入路;3例)、前切除术加直肠固定术(2例)、德洛姆手术(1例)和肛门环缩术(1例)。平均随访时间为50个月(范围9至115个月)。
在此期间未观察到直肠完全脱垂的再次发作。术前,3例患者存在失禁,需要使用会阴垫。再次手术未能恢复这3例患者中的任何一例的大便失禁。1例患者在肛门环缩术后因无关原因在术后死亡。
复发性直肠脱垂的手术治疗有望缓解脱垂,但不一定能改善大便失禁。经会阴直肠切除术可安全地重复进行。除非外科医生在再次手术中能够切除先前的吻合口,否则切除性手术可能会导致两个吻合口之间出现缺血段。如果最初进行的是切除性手术且失败,在复发性直肠脱垂的处理中应强烈考虑非切除性手术,如德洛姆手术。
