Sixty-seven patients with a J-shaped ileonanal pouch were studied over a 2-year period with regular recording of sphincter and pouch characteristics and analysis of their role in functional outcome. Although there was a 27 per cent permanent reduction in resting anal pressure (RAP) (P less than 0.001), two-thirds of the patients still had a RAP within the(More)
The objective was to assess the prevalence and risk factors for co-occurring pelvic floor disorders (PFDs): urinary incontinence (UI), symptomatic pelvic organ prolapse (sPOP), and fecal incontinence (FI), 20 years after one vaginal (VD) or one cesarean (CS) delivery. We carried out a registry-based national cohort study of primiparae who delivered during(More)
We describe the prevalence of symptomatic pelvic organ prolapse (sPOP), urinary incontinence (UI), fecal incontinence (FI) and obstetric anal sphincter injury (OASI) 20 years after one vacuum extraction (VE) delivery compared with one spontaneous vaginal delivery (SVD) or one acute caesarean section (ACS). We performed a register-based national cohort study(More)
A new technique for manovolumetric investigation of rectoanal function allowing for simultaneous recording of rectal volume, anal pressure and external sphincter EMG in response to graded rectal distension was developed. Distension pressure was generated by a water column between two reservoirs. Volume was recorded as shifts of water between the reservoirs.(More)
Pouch volume, motility, sensory function and integrated pouch-anal mechanisms during graded isobaric distension of the pouch were prospectively studied in 67 patients with a J pouch-anal anastomosis. The findings were related to functional outcome. Thirty-six normal controls were studied for comparison. In contrast with normal rectum, the ileal pouch(More)
Rectoanal manovolumetry during graded isobaric rectal distension was carried out in 12 women with severe constipation classified as slow transit constipation (Arbuthnot Lane's disease). The resting anal sphincter pressure, the rectoanal inhibitory reflex and the rectal capacity were all normal. While thedistension volumes required to elicit sensation of(More)
The rectal expansion and concomitant sensory function on graded, isobaric, rectal distension within the interval 5-60 cm H2O was investigated in 36 healthy young volunteers. Anal pressure and electromyography (EMG) from the external anal sphincter were simultaneously recorded. Rectal distension caused an initial rapid expansion followed by transient, often(More)
The effects of age, gender, and parity on rectoanal function were examined in a cross-sectional population study, including 68 normal subjects (32 men and 36 women) aged 23 to 91 years. Rectal volumetry was evaluated with graded isobaric rectal distension with 5-60 cm H2O in combination with anal manometry. Data were analysed by use of the multiple(More)
Although patients' satisfaction may be high after restorative proctocolectomy the functional results are still far from perfect. Increased bowel frequency and imperfection in continence are common. Pouch volume and anal sphincter status are important determinants for the outcome. The aim of the present study was to evaluate if balloon dilatation of the(More)
