1. Anal fistulae - Three-dimensional endoanal ultrasound and outcomes of collagen plug treatment
Sammanfattning : Background: The treatment of complex anal fistulae remains a therapeutic challenge. Early anal fistula plug (AFP) studies showed high success rates, while later reports demonstrated success rate of 13-100% at usual follow-up of 6-24 months. LÄS MER
2. Anatomical and physiological aspects of anorectal dysfunction
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.

3. ULTRASOUND STUDIES ON PELVIC FLOOR PHYSIOLOGY AND OBSTETRIC PERINEAL TEARS
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. Sphincter injuries and anal incontinence after vaginal delivery : a clinical and physiological study
Sammanfattning : 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. LÄS MER
5. Human papillomavirus in men who have sex with men, transgender women and people living with HIV in Pakistan
Sammanfattning : Background: Anal infection with human papillomavirus (HPV) and associated anal squamous intraepithelial lesions (ASIL), are more prevalent among men who have sex with men (MSM) particularly among MSM and transgender women living with HIV The high prevalence of HIV among MSM and transgender women in Pakistan is a significant health concern and access to screening and health-seeking is often delayed due to stigmatization and discrimination. Anal Papanicolaou (Pap) screening may have utility in the identification of these lesions and is a cost- effective modality for anal cancer prevention among MSM, but no such data are available for Pakistan.
