    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.

    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.

    Randomized trial comparing three forms of pelvic floor repair for neuropathic faecal incontinence
    (1993) Deen, K.I.; Oya, M.; Ortiz, J.; Keighley, M.R.
    A randomized controlled trial in women with neuropathic faecal incontinence compared total pelvic floor repair (n = 12) with anterior levatorplasty and sphincter plication alone (n = 12) and postanal repair alone (n = 12). Review at 6 and 24 months indicated that results were significantly better for total pelvic floor repair than either of the other procedures. Comlete continence was achieved in eight of the 12 patients 2 years after total pelvic floor repair. Only total repair significantly elongated the anal canal. Both total pelvic floor repair and anterior levatorplasty improved sensation in the upper anal canal.

    The Prevalence of anal sphincter defects in faecal incontinence: a prospective endosonic study
    (British Medical Assosiation, 1993) Deen, K.I.; Kumar, D.; Williams, J.G.; Olliff, J.; Keighley, M.R.
    Forty six patients (median age 61 years; 42 women) with faecal incontinence and 16 age and sex matched controls undergoing a restorative proctocolectomy were assessed by clinical examination, anorectal physiology, and anal endosonography. Forty patients (87%) with faecal incontinence had a sphincter defect demonstrated on anal endosonography (31 external and 21 internal anal sphincter defects). The commonest cause of faecal incontinence was obstetric trauma. This occurred in 35 women, 30 of whom exhibited a morphological defect in the anorectal sphincter complex. In 22 of these patients with a history of a perineal tear or episiotomy, 21 (95%) had a sphincter defect. Sphincter defects were commonly located at the level of the midanal canal.

    Scintigraphic defecography: quantitative and dynamic assessment of anorectal function
    (Lippincott Williams and Wilkins, 1993) Hutchinson, R.; Mostafa, A.B.; Grant, E.A.; Smith, N.B.; Deen, K.I.; Harding, L.K.; Kumar, D.
    PURPOSE: Conventional assessment of anorectal function with defecating videoproctography is semiquantitative and the high radiation exposure precludes prolonged or repeated testing. The aim of this study was to develop a dynamic scintigraphic method of assessing anorectal function. METHODS: Fourteen patients with fecal incontinence, 18 patients with chronic constipation, and 8 control subjects were assessed by scintigraphicdefecography. This involves introduction of a technetium-99m-radiolabeled artificial stool into the rectum of the subject and acquisition of gamma camera images during evacuation. RESULTS: Mean evacuation rate was 2.8 percent/second in incontinent patients and 0.9 percent/second in constipated patients (P < 0.001). The mean anorectal angles were 136 degrees and 133 degrees, respectively. There were 18 cases of pelvic floor descent and 6 rectoceles. Scintigraphicdefecography provides quantitative information on rectal evacuation. Anorectal angle and pelvic floor movement can be examined. The radiation dose to pelvic organs is significantly less than with videoproctography. CONCLUSION: We believe that scintigraphic defecography is the investigation of choice for objective and dynamic assessment of anorectal function
