Intervention/exposure
Study type

Query!
Description of intervention(s) / exposure
The intervention is to switch off the neuromodulation device which is the implanted pulse generator that stimulates the sacral nerve. The device is switched off for 6 weeks by a nurse. To monitor adherence to the intervention the remote control which the patient usually uses to turn their device off or on is placed in a security sealed envelope. Each cycle includes 2 weeks of washout period.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients implanted with a permanent sacral nerve stimulator at Concord Hospital will be assessed for eligibility.
Query!
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A specialist nurse, who is otherwise not involved with data collection and analysis will undertake all randomisation. Both the investigators and the patients are blinded to randomisation arm assigned. A computer generated block randomisation will be performed and sealed in an opaque envelope. The envelopes are numbered and drawn sequentially at the point of randomisation.

Summary
Brief summary
Sacral Neuromodulation or SNM is a well-established treatment for bowel leakage, also known as faecal incontinence. It uses a small device (a stimulator) that is implanted under the skin in the upper buttock area. It then transmits electrical pulses through a small wire that is positioned close to the sacral nerve to improve bowel control and function. Despite being very successful for the treatment of faecal incontinence, the exact mechanism by which it works remains unknown. It is possible that SNM influences the way that the brain and gut interact by ‘resetting’ its function back to normal, a bit like restarting a computer after it ‘crashes’. If this is true, long-term SNM may not be necessary to control symptoms. The aim of this study is to assess the impact of SNM on bowel symptoms and bowel control, particularly when SNM is switched off. The group studied will include patients with faecal incontinence who have successfully been stimulated for at least 6 months. A total of 20 patients will be recruited and randomised into two groups; each group will have two cycles of different exposure. Each cycle will last for 6 weeks and will involve either turning the stimulator Off or On. Patients and assessors will be unaware whether the stimulator is On or Off, so as to reduce the effect of bias. At each 6-week cycle, all patients recruited will attend the hospital to adjust their stimulator and to complete a questionnaire and undergo physiology tests to measure bowel control and function. At the end of the study the SNM will be switched back to the original setting. Study outcomes will involve assessment of bowel symptoms, severity of faecal incontinence, quality of life scores and anorectal physiological function. This study will provide important information in understanding and treating disorders of bowel function and bowel leakage.
