2. 1. 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

4. 2. Preoperative staging and radiotherapy in rectal cancer surgery

   Author : Johan Pollack; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Rectal cancer; radiotherapy; adverse effects; endorectal ultrasound; anorectal manometry; endoanal ultrasound; quality of life; anal incontinence; preoperative staging;

   Abstract : Background: Rectal cancer affects approximately 2 000 people in Sweden every year. The overall survival rate is approximately 50% after five years. During the last decades the survival has increased and the local recurrence rate has declined. This can be attributed to improved surgical techniques and introduction of preoperative radiotherapy.

5. 3. Anal incontinence and obstetric sphincter tears

   Author : Johan Nordenstam; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : 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. READ MORE

   Abstract : Background: Up to 80% of women are affected by a perineal laceration after their first vaginal birth. An estimated 40–50% of lacerations involve the perineal muscles, and up to 7% are obstetric anal sphincter injuries (OASI). READ MORE
