Abstract
Virtually all untreated patients with familial adenomatous polyposis develop colorectal carcinoma. Thus, prophylactic colectomy is indicated. Detractors of ileal pouch-anal anastomosis prefer ileorectal anastomosis for teenagers because of the potential negative impact of ileal pouch-anal anastomosis on quality of life. The aim of this study was to assess the effects on quality of life of ileal pouch-anal anastomosis in teenagers with familial adenomatous polyposis. Between 1981 and 1998, 48 teenagers underwent ileal pouch-anal anastomosis for familial adenomatous polyposis. One patient had proctectomy and ileal pouch-anal anastomosis after previous ileorectal anastomosis. A temporary diverting loop ileostomy was established in 42 patients (87.5 percent). One patient had colonic carcinoma diagnosed preoperatively. Two other patients were found to have unsuspected rectal cancer at surgery. Mean follow-up (± standard deviation) in 43 patients was 80.5±42 months. There was no immediate postoperative mortality. Postoperative complications included pelvic sepsis (3 patients; 1 requiring reoperation) and bleeding (1 patient; no surgery required). One patient died of metastatic colonic carcinoma. Ten patients required reoperation, seven had bowel obstruction, one had portal hypertension, and two required an ileostomy. The mean (± standard deviation) daytime and nighttime stool frequency was 4±1.5 and 1±1, respectively. One patient reported daytime and nighttime incontinence, and two patients reported nighttime incontinence only. No patient experienced impotence or retrograde ejaculation. Social, sexual, sport, housework, recreation, family, travel, and work activities were improved or unchanged in 82.5, 87, 80, 90, 80, 92.5, 77.5, and 89 percent of patients, respectively. Three male patients fathered children, and three female patients had a total of six children after normal pregnancies and deliveries. The impact of ileal pouch-anal anastomosis on quality of life was favorable in the majority of teenagers. The risk of rectal cancer should be the major consideration before proposing an operation to teenagers with familial adenomatous polyposis.
