  1. 1. Anal Fistula : Aspects of Aetiology, Diagnosis and Prognosis After Surgical Treatment

    Author : Ulla-Maria Gustafsson; Wilhelm Graf; Torgny Svenberg; Uppsala universitet; []
    Keywords : Surgery; anal fistula; risk factors; endoanal advancement flap; anal incontinence; endoanal ultrasound; magnetic resonance imaging; gentamicin-collagen; micro perfusion; laser Doppler flowmetry; Kirurgi;

    Abstract : Patients with idiopathic anal fistula (n=85) were compared with 215 control subjects, matched for age and sex, through a 180-item questionnaire. Obesity, smoking, constipation and bowel symptoms associated with IBS were more common in the patients. READ MORE

  2. 2. Endosonography of the anal spincter in women with particular reference to obstetric sphincter tears

    Author : Marianne Starck-Söndergaard; Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; anal sphincter; childbirth; obstetric sphincter tears; Anal endosonography; endosonographic sphincter defects; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : The aim of this thesis was to study the endosonographic morphology of the anal sphincter in women, to establish an endosonographic sphincter defect score and to relate it to anal incontinence and anal sphincter pressure. A further aim was to determine intra-observer and inter-observer agreement in detection of endosonographic anal sphincter defects. READ MORE

  3. 3. Anatomical and physiological aspects of anorectal dysfunction

    Author : Geert Morren; Anders Mellgren; Linköpings universitet; []
    Keywords : Anal canal; Anal-sphincter repair; Audit; Magnetic resonance imaging; Magnetic stimulation; Latency; Pelvic floor; Sacral roots; MEDICINE; MEDICIN;

    Abstract : Objective: To analyse the results of anal-sphincter repair; to examine the feasibility of motor latency measurements of the anal sphincter after magnetic sacral stimulation in healthy subjects, patients with a spinal cord injury and patients with faecal incontinence, using a new recording technique; to study, in the same 3 groups, the effects ofphasic magnetic sacral root stimulation on the anal sphincter and rectum; to describe normal, undisturbed anatomy of the anal canal and perianal structures in both men and nulliparous women using high-resolution phased array magnetic resonance imaging; to study pelvic floor movements in healthy volunteers of both sexes using a new instrument.Methods: Latencies were recorded with an intraanal, bipolar sponge electrode and an intrarectal ground electrode.

  4. 4. ULTRASOUND STUDIES ON PELVIC FLOOR PHYSIOLOGY AND OBSTETRIC PERINEAL TEARS

    Author : Ann-Kristin Örnö; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; sexuality; Obstetrik; andrology; bladder neck descent; rectoanal inhibitory reflex; rectal sensation; Hirschsprung´s disease; Obstetrics; gynaecology; Valsalva manoeuvre; perineal tears; Pelvic floor; anal sphincter; gynekologi; andrologi; reproduktion; sexualitet;

    Abstract : Repair of obstetric perineal tears is one of the most frequent procedures in surgical practice. Despite repair such tears may result in anal and urinary incontinence and prolapses of the pelvic floor, problems in need of surgical repair later in life. READ MORE

  5. 5. Sphincter injuries and anal incontinence after vaginal delivery : a clinical and physiological study

    Author : Jan Zetterström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Obstetric sphincter injury; anal sphincter defect; anal incontinence; perineal body; endoanal ultrasonography; anorectal manometry; pudendal nerve terminal motor latency;

    Abstract : Objective: To investigate the frequency and degree of anal incontinence after vaginal delivery in primiparous women, to determine risk factors for obstetric sphincter tears and to evaluate outcome of primary repair, to evaluate perineal body measurement (PBM) in patients with obstetric sphincter injuries, to study anal sphincter morphology and function before and after delivery, and to evaluate primiparous women who had sustained a sphincter tear or developed anal incontinence after delivery. Methods: Questionnaires regarding anal incontinence before pregnancy, at five and nine months after delivery were used. READ MORE
