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

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

4. 3. Anal incontinence and obstetric sphincter tears

   Författare :Johan Nordenstam; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : PURPOSE: To evaluate the prevalence of anal incontinence (AI) in primiparous women five years after their first delivery; to investigate if an 8-12 hour time delay of primary repair affects AI at 1-year follow-up; to study the association between endoanal ultrasonography and anorectal manometry in relation to AI in primiparous women; to evaluate whether an endoanal ultrasonographic derived sphincter length-index correlates to subjective AI. METHODS: Primiparous women were prospectively followed with questionnaires before the pregnancy, at 5 and 9 months, and 5 years after the delivery. LÄS MER

5. 4. The long-term effects of obstetrical anal sphincter injury on pelvic floor function

   Författare :Ida E K Nilsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anal incontinence; Caesarean section; Faecal incontinence; Pelvic organ prolapse; Severity; Urinary incontinence; Vaginal delivery;

   Sammanfattning : Background: As women live longer, the long-term effects of childbirth may negatively affect their quality of life and professional careers. Aim: This thesis investigates the long-term effects of vacuum extraction (VE) and one and two obstetrical anal sphincter injuries (OASIs). LÄS MER

7. 5. Anatomical and physiological aspects of anorectal dysfunction

   Författare :Geert Morren; Anders Mellgren; Linköpings universitet; []
   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.
