Following the operation, the patient is asked to wait for six weeks before the band can be filled. During this time, the patient is advised to ensure regular, soft bowel movements, which prevent the wounds – in particular around the sphincter – from being subjected to additional strain. The wounds around the skin pockets in the lower abdomen where the valve and activator lie, should be fully healed beforehand to avoid pain when the system is activated. Once the six weeks have passed, the patient comes back into the hospital and the anal band is filled. Then a sphincter manometry is carried out, and the level of continence is assessed using stress tests.
This filling and subsequent testing ensure the band provides the patient with a closing pressure very close to that of a healthy sphincter muscle.
