    Författare :Pernilla Stenström; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perineal ultrasonography; sphincter anatomy; pelvic floor; appendicostomy; adolesence; constipation; soiling; fecal incontinence; quality of life; anorectal malformations;

    Sammanfattning : Abstract: Background : Anorecta l malformation s (ARM) occur in 4: 10000 newborn children with the gender distribut ion 1:1.5 females:males. The reconstruction of ARM, posterior sagiccal anorectal plasty (PSARP), was implemenred worldwide in the late 1980s and therefore the follow-ups are limited. LÄS MER

    Sammanfattning : 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. LÄS MER

  4. 3. Anatomical and physiological aspects of anorectal dysfunction

    Nyckelord :Anal canal; Anal-sphincter repair; Audit; Magnetic resonance imaging; Magnetic stimulation; Latency; Pelvic floor; Sacral roots; MEDICINE; MEDICIN;

    Sammanfattning : 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.
