Article: Sacral nerve modulation for defaecation and micturition disorders in patients with spina bifida.
[show abstract] [hide abstract]
ABSTRACT: Sacral nerve modulation is a well accepted method for the treatment of defaecation disorders and voiding dysfunction. Results of sacral nerve modulation in patients with spinal cord lesions are not well assessed, but preliminary results look poor. Therefore, the purpose of this study was to assess the effectiveness of sacral nerve modulation for defaecation disorders and voiding dysfunction in patients with spina bifida. Consecutive patients with spina bifida suffering from a myelomeningocele and combined faecal and urinary functional disorders that were eligible for peripheral nerve evaluation (PNE) were studied. A permanent sacral nerve modulation implantation was performed after successful PNE. Ten patients (four female) were included in this study with a median age of 26.4 (range 11.1-41.0) years. In two the PNE was not possible. The median faecal incontinence days (6.0 vs 3.5) and episodes (8.5 vs 3.5) per 21 days decreased significantly during the 3-week period of PNE (P = 0.033). Only 3/10 (30%) patients had a more than 50% improvement and proceeded to a permanent sacral nerve modulation implantation. In one patient it was not possible to perform the permanent implant. Preliminary results of sacral nerve modulation in a subgroup of spina bifida patients with combined faecal and urinary functional disorders look promising, but long-term results in larger patient groups need to be studied.Colorectal Disease 05/2011; 14(4):508-14. · 2.93 Impact Factor -
Article: Sacral nerve stimulation for intractable constipation.
[show abstract] [hide abstract]
ABSTRACT: Traditional surgical procedures for intractable idiopathic constipation are associated with a variable outcome and substantial morbidity. The symptomatic response, physiological effect and effect on quality of life of sacral nerve stimulation (SNS) were evaluated in patients with constipation (slow transit and normal transit with impaired evacuation). In a prospective study at five European sites patients who failed conservative treatment underwent 21 days test stimulation. Patients with >50% improvement in symptoms underwent permanent neurostimulator implantation. Primary end points were increased defecation frequency, decreased straining and decreased sensation of incomplete evacuation. 62 patients (55 female, median age 40 years) underwent test stimulation, of whom 45 (73%) proceeded to chronic stimulation. 39 (87%) of these 45 patients achieved treatment success. After a median 28 (range 1-55) months follow-up, defecation frequency increased from 2.3 to 6.6 evacuations per week (p<0.001). Days per week with evacuation increased from 2.3 to 4.8 (p<0.001). There was a decrease in time spent toileting (10.5 to 5.7 min, p=0.001), straining (75-46% of successful evacuations, p<0.001), perception of incomplete evacuation (71.5-46% of successful evacuations, p<0.001) and subjective rating of abdominal pain and bloating (p<0.001). Cleveland Clinic constipation score (0=no to 30=severe constipation) decreased from 18 to 10 (p<0.001). Visual analogue scale (VAS) score (0=severe to 100=no symptoms) increased from 8 to 66 (p<0.001). Patients with slow and normal transit benefited. Quality of life significantly improved. Colonic transit normalised in half of those with baseline slow transit (p=0.014). SNS is effective in the treatment of idiopathic slow and normal transit constipation resistant to conservative treatment.

Article: Sacral neuromodulation for the treatment of chronic functional anorectal pain: a single center experience.
[show abstract] [hide abstract]
ABSTRACT: Treatment of functional anorectal pain disorders remains a challenge. The purpose of this study is to describe a single center experience with sacral neuromodulation for the treatment of chronic functional anorectal pain. This is a retrospective study based on prospectively collected data of patients treated with sacral neuromodulation for functional anorectal pain from April 2005 to August 2008. Symptoms were analyzed using a visual analog scale pain score (0 to 10). A 7-point Likert scale was used to rate global perceived effect. All patients had a percutaneous nerve evaluation and subsequent test stimulation to assess sacral neuromodulation outcome prior to permanent implantation. Patients were eligible for permanent sacral neuromodulation in case of a pain score <3 during test stimulation and/or >50% decrease in the pain score compared to baseline. Nine patients (2 males) were included in this study. Mean age was 53.8 years (27.6 to 74.0). Four patients (1 male) had successful test stimulation and were eligible for permanent implantation. Median pain score decreased from 8.0 (6.0 to 9.0) to 1.0 (0 to 2.0). All patients experienced a lasting improvement during the follow-up till 24 months. Global perceived effect in successful patient was 1 (completely recovered) in one patient and 2 (much improved) in three patients. This study showed that sacral neuromodulation can be a successful treatment for functional anorectal pain not responding to other treatments. Improvement obtained during test stimulation is a good predictor (diagnostic) for sustained success of permanent sacral neuromodulation.Pain Practice 09/2009; 10(1):49-53. · 2.21 Impact Factor -
Article: Sacral nerve modulation and other treatments in patients with faecal incontinence after unsuccessful pelvic floor rehabilitation: a prospective study.
[show abstract] [hide abstract]
ABSTRACT: Sacral nerve modulation (SNM) is a minimally invasive technique for the treatment of faecal incontinence. This study investigates the results of SNM after negative outcome of a standardized pelvic floor rehabilitation (PFR) programme for the treatment of faecal incontinence. A prospective cohort study was performed between December 2001 and August 2007. Consecutive patients who visited the outpatient department for faecal incontinence were included in a multicentre study and treated with standardized PFR. Those with an unsuccessful result who were eligible for SNM were included in the present study. Failures at test stimulation or SNM received another treatment. Clinical outcome, Vaizey scores and Hirschsprung's disease/anorectal malformation quality-of-life (EQ-5D and HAQL) were assessed during follow-up in patients with SNM and in patients with other treatments (OT). Adverse events (AE) were documented. Thirty-five patients (mean age 59.7 years; 31 females) were included. Twenty-one had a successful test stimulation and 19 patients proceeded to a SNM implant. Incontinence episodes per week decreased significantly from 11.1 +/- 11.7 to 1.9 +/- 2.6 during test stimulation (P < 0.0001) and SNM over 24.1 months follow-up. The overall success rate was 49% (17/35). The patients with unsuccessful test stimulation or SNM received OT. The Vaizey score improved in both SNM (18.2 +/- 3.5 vs 13.7 +/- 4.8; P = 0.004) and other treatment (18.2 +/- 3.5 vs 13.9 +/- 6.9; P = 0.019). The HAQL scale improved significantly during SNM in all subscales (P < 0.005), but not in the other treatment group. Eight AE occurred during test stimulation (23%) and six AE after permanent implantation (26%). Sacral nerve modulation improves disease specific quality of life significantly compared with other treatment.Colorectal Disease 02/2009; 12(4):334-41. · 2.93 Impact Factor -
Article: The artificial bowel sphincter for faecal incontinence: a single centre study.
[show abstract] [hide abstract]
ABSTRACT: Faecal incontinence (FI) is a socially devastating problem. The treatment algorithm depends on the aetiology of the problem. Large anal sphincter defects can be treated by sphincter replacement procedures: the dynamic graciloplasty and the artificial bowel sphincter (ABS). Patients were included between 1997 and 2006. A full preoperative workup was mandatory for all patients. During the follow-up, the Williams incontinence score was used to classify the symptoms, and anal manometry was performed. Thirty-four patients (25 women) were included, of which, 33 patients received an ABS. The mean follow-up was 17.4 (0.8-106.3) months. The Williams score improved significantly after placement of the ABS (p<0.0001). The postoperative anal resting pressure with an empty cuff was not altered (p=0.89). The postoperative ABS pressure was significantly higher then the baseline squeeze pressure (p=0.003). Seven patients had an infection necessitating explantation. One patient was successfully reimplanted. The artificial bowel sphincter is an effective treatment for FI in patients with a large anal sphincter defect. Infectious complications are the largest threat necessitating explantation of the device.International Journal of Colorectal Disease 01/2008; 23(1):107-11. · 2.38 Impact Factor -
Article: A randomized physiotherapy trial in patients with fecal incontinence: design of the PhysioFIT-study.
[show abstract] [hide abstract]
ABSTRACT: Fecal incontinence (FI) is defined as the recurrent involuntary excretion of feces in inappropriate places or at inappropriate times. It is a major and highly embarrassing health care problem which affects about 2 to 24% of the adult population. The prevalence increases with age in both men and women. Physiotherapy interventions are often considered a first-line approach due to its safe and non-invasive nature when dietary and pharmaceutical treatment fails or in addition to this treatment regime. Two physiotherapy interventions, rectal balloon training (RBT) and pelvic floor muscle training (PFMT) are widely used in the management of FI. However, their effectiveness remains uncertain since well-designed trials on the effectiveness of RBT and PFMT versus PFMT alone in FI have never been published. A two-armed randomized controlled clinical trial will be conducted. One hundred and six patients are randomized to receive either PFMT combined with RBT or PFMT alone. Physicians in the University Hospital Maastricht include eligible participants. Inclusion criteria are (1) adults (aged > or = 18 years), (2) with fecal incontinence complaints due to different etiologies persisting for at least six months, (3) having a Vaizey incontinence score of at least 12, (4) and failure of conservative treatment (including dietary adaptations and pharmacological agents). Baseline measurements consist of the Vaizey incontinence score, medical history, physical examination, medication use, anorectal manometry, rectal capacity measurement, anorectal sensation, anal endosonography, defecography, symptom diary, Fecal Incontinence Quality of Life scale (FIQL) and the PREFAB-score. Follow-up measurements are scheduled at three, six and 12 months after inclusion. Skilled and registered physiotherapists experienced in women's health perform physiotherapy treatment. Twelve sessions are administered during three months according to a standardized protocol. This section discusses the decision to publish a trial protocol, the actions taken to minimize bias and confounding in the design, explains the choice for two treatment groups, discusses the secondary goals of this study and indicates the impact of this trial on clinical practice.
