SP7.2.4 Evaluation of Non-crosslinked Acellular Porcine Dermal Mesh – A Single Centre Experience

Abstract

Aims We report our experience with a cellular porcine dermal non-crosslinked biological mesh (EGIS®). We conducted a review of indications and outcomes of patients requiring the mesh for incisional hernia/complex abdominal wall reconstruction with component separation, parastomal hernia repairs and ELAPE. Patients were followed for a minimum of 6 and assessed for recurrence, seroma formation and chronic pain. Secondary outcome was the assessment of ease of use by the Surgeon – suturing and pliability. Method A retrospective case notes review of patients requiring biological mesh (EGIS®) from 2016 to present. A qualitative survey about ease of use of EGIS® for operations studied was sent to all Consultant Surgeons. Results EGIS® mesh was used in 38 patients: 23 Hernia repairs – 13 Incisional, 8 Parastomal, 2 Paraumbilical; 12 Pelvic floor repairs after ELAPE; and 3 abdominal wall reconstructions. Hernia recurrence occurred in 12 (32%), seroma 7 (18%) and chronic pain 7 (18%). The highest complications occurred in the incisional and parastomal hernia groups. Incisional hernia: recurrence in 5 (38%), seroma in 5 (38%) and chronic pain in 3 (23%). Parastomal hernia: recurrence in 3 (38%), chronic pain 2 (25%), seroma 1 (13%). Consultants scored the mesh 4.3 to 4.5 out of 10 for pliability, ease of use and suturing. Conclusion Biological mesh is used to reinforce hernia repairs in contaminated or potentially contaminated fields. Non-crosslinked meshes are preferred for their greater cellular infiltration from host tissue with improved integration. Our experience with this mesh shows a high complication rate and requires re-evaluation.
