This is a single-centre, prospective, open-label pilot clinical study designed to evaluate the safety and performance of the TIES® (Transcutaneous Implant Evacuation System) in adult patients requiring a permanent ileostomy or colostomy. Eligible patients will undergo surgical implantation of the TIES® Port as part of stoma revision. Participants will be followed for 16 weeks post-implantation to assess device safety, tissue ingrowth and healing, performance, durability, and impact on quality of life. Safety will be evaluated through monitoring of adverse events, while performance and usability will be assessed using structured questionnaires and clinical assessments. Quality of life will be measured using the validated Stoma-QoL questionnaire. The study aims to generate clinical evidence on the feasibility and safety of the TIES® system as an alternative to conventional stoma management.
