Feasibility study of a novel stoma device

Intervention: - Initiation of device for recycling stoma and fistula effluent. - A tube will be inserted into the stoma orifice to enable stoma output recycling. Who will deliver the intervention: - The intervention will be delivered by a member of the trial team initially, and may subsequently be self-delivered by a patient. Number of times to be delivered: - The intervention will be delivered over increasing periods of time during the trial, initially for single short periods (5-10 minutes), then progressively increasing usage to trials over 3 days and eventually over 6 week periods. Setting: - hospital and/or home environment Strategies to monitor adherence: - research team monitoring / observations initially and later patient self-reporting.
