Item Longterm results of total pelvic floor repair for postobstetric fecal incontinence(Lippincott Williams and Wilkins, 1997) Korsgen, S.; Deen, K.I.; Keighley, M.R.B.PURPOSE:This study was designed to assess the long-term results of total pelvic floor repair for postobstetric neuropathic fecal incontinence. METHOD: Sixty-three of 75 women who had undergone total pelvic floor repair for postobstetric neuropathic fecal incontinence were traced and interviewed a median of 36 (18-78) months after surgery. Thirty-nine patients agreed to repeat anorectal physiology. RESULTS: Six patients required further surgery for persistent incontinence (colostomy, 4; graciloplasty, 2). For the remaining 57 patients, incontinence improved greatly in 28 (49 percent) patients, mildly in 13 (23 percent), and not at all in 16 (28 percent); daily incontinence was present in 41 patients (73 percent) before the operation but persisted in 13 (23 percent). Only eight (14 percent) patients were rendered completely continent; those with marked improvement were socially more active than those with little or no improvement. Resting and maximum squeeze pressures, anal canal sensation, rectal sensation, and pudendal nerve terminal motor latency did not predict outcome. Perineal descent, obesity, and a history of straining before the operation were all associated with a poor outcome. CONCLUSION: Total pelvic floor repair rarely renders patients with postobstetric neuropathic fecal incontinence completely continent but substantially improves continence and lifestyle in approximately one-half of them. The operation is less successful in obese patients and in those with a history of straining or perineal descent.Item Randomized trial of internal anal sphincter plication with pelvic floor repair for neuropathic fecal incontinence(Lippincott Williams and Wilkins, 1995) Deen, K.I.; Kumar, D.; Williams, J.G.; Grant, E.A.; Keighley, M.R.B.PURPOSE:This study was designed to examine the role of adjuvant internal anal sphincter plication in women with neuropathic fecal incontinenceundergoing pelvic floor repair. METHODS: We completed a randomized trial with symptomatic and physiologic assessment before and after surgery. RESULTS: There was no symptomatic advantage of adding internal sphincter plication; the mean improvement of functional score was 3.61 +/- 1.82 (standard deviation; P < 0.01) following pelvic floor repair alone compared with 2.80 +/- 1.66 (standard deviation; P < 0.01) when adjuvant internal and sphincter plication was added. The addition of internal sphincter plication was associated with a significant fall in maximum anal resting and squeezing pressures (P < 0.01). CONCLUSIONS: Addition of internal sphincter plication is not advised in women with neuropathic fecal incontinence treated by pelvic floor repair.Item Randomised trial to determine the optimum level of pouch-anal anastomosis in stapled restoractive proctocolectomy(Lippincott Williams and Wilkins, 1995) Deen, K.I.; Williams, J.G.; Grant, E.A.; Billingham, C.; Keighley, M.R.B.PURPOSE:This study was undertaken to identify the optimum level of stapled ileal pouch-anal anastomosis. METHOD: A prospective, randomized trial was completed to compare double-stapled ileoanal anastomosis placed at the top of anal columns (high, n = 26) with anastomosis at the dentate line (low, n = 21). RESULTS: There was no significant difference in the overall complication rate between operations (high, n = 7, vs. low, n = 8; P < 0.21). Pouch-anal functional score (scale 0-12; 0 = excellent, 12 = poor) was significantly better in the high anastomosis group (median (range): 2 (1-9) vs. 5.5 (1-12); P < 0.05). Incontinence occurred in only two patients randomized to high anastomosis compared with six in the low anastomosis group. Nocturnal soiling was reported in three patients after high anastomosis and in six patients after dentate line anastomosis. Both operations caused a significant but comparable reduction of maximum and resting pressure (31 percent after high anastomosis (P < 0.05); 23 percent after low anastomosis (P < 0.05)). However, a significant fall in functional length of the anal canal was only seen after a low pouch-anal anastomosis (P < 0.05). CONCLUSION: Stapled pouch-anal anastomosis at the top of anal columns gives better functional results compared with a stapled anastomosis at the dentate line.
