简要总结
RATIONALE: An anal sphincter prosthesis may replace the need for a permanent colostomy and may improve the quality of life of patients who are undergoing surgery for anal or rectal cancer.
PURPOSE: Clinical trial to study the effectiveness of an anal sphincter prosthesis in treating patients who have anal or rectal cancer and are undergoing surgery to remove the anus and rectum.
详细描述
OBJECTIVES:
- Determine the risk of complications and feasibility of total anorectal reconstruction using the Acticon Neosphincter prosthesis after abdominoperineal resection in patients with anal or rectal cancer.
- Determine continence, bowel function, and quality of life of patients treated with this surgery.
OUTLINE: Patients undergo abdominoperineal resection (APR) with perineal colostomy and diverting loop ileostomy. At least 3 months after APR, patients undergo placement of the Acticon Neosphincter prosthesis. At least 6 weeks after prosthesis placement, the prosthesis is activated. When the patient demonstrates the ability to operate the prosthesis, the ileostomy is reversed.
Quality of life is assessed at 6 and 12 months and then annually thereafter.
Patients are followed at 6 and 12 months and then annually thereafter.
