When a fistula or ostomy becomes “unpouchable,” consider soft tissue revision followed by management with a fistula isolation device.
Open wounds, uneven or scarred tissue, retracted stomas, and fistulas under wound edges can make reliable pouching impossible. Recurrent leakage leads to maceration, prolonged hospitalization, and patient frustration.
This is where RISP provides structure.
What Is RISP?
RISP stands for:
Revise. Isolate. Skin Graft. Pouch.
It is a staged surgical technique designed to reconstruct peri-stomal or peri-fistula soft tissue and ultimately transition the patient to a standard, easy-to-manage ostomy appliance.
The sequence matters:
1. Revise
Surgically revise soft tissue to fully expose the stoma or fistula and create a viable pouching surface (without entering the peritoneum).
2. Isolate
Control and divert effluent using isolation devices and negative pressure wound therapy (NPWT) to heal the wound.
3. Skin Graft
Place a skin graft around the stoma or fistula once output is controlled. Protect the graft with continued isolation and NPWT support.
4. Pouch
Transition to a standard ostomy appliance once the graft has healed, restoring independence and reliability.
Why Isolation Is Central
Isolation is the turning point in RISP. Effluent control creates the conditions necessary for graft survival and predictable reconstruction.
RISP highlights the importance of multidisciplinary collaboration and environmental control in complex abdominal reconstruction.
