A percutaneous ostomy implant for implantation into the abdominal wall of a patient comprises: a connecting member for mounting an external detachable device thereto; a first tubular ingrowth member depending from the connecting member; and a second tubular ingrowth member depending from the connecting member and being radially outwardly spaced from the first tubular ingrowth member. The first tubular ingrowth member is adapted to receive a bowel segment within it to form a stoma and serosal tissue of that bowel segment may infiltrate the first tubular ingrowth member. The second tubular member is adapted to abut dermal tissue such that the dermal tissue may infiltrate the second tubular ingrowth member, thereby securing and sealing the ostomy implant to the dermis.
