EP.TH.108A Descriptive Case Series of Incisional Hernia Repair Using Dual Mesh Technique

Abstract

Abstract Aims Incisional hernias are a common complication after surgery that cause significant patient morbidity. Symptomatic patients are offered repair but many surgical techniques exist, with abdominal wall reconstruction becoming preferable for large complex defects. This paper describes our experience of abdominal wall reconstruction using a dual mesh technique. Method 22 patients underwent incisional hernia repair between March 2019 and September 2020. All patients received dual mesh, placed in retrorectus or transversalis fascial/retromuscular space. Absorbable BIO-A GORE mesh was used with a polypropylene mesh above. All patients were followed up to assess for complications and recurrence. Results No patients experienced fistula formation, long-term pain or obstructive symptoms. We report one true hernia recurrence (4.5%) and one case of infected mesh (4.5%), these both await further treatment. One patient had a proven wound infection which resolved with conservative treatment. 4 patients (18.2%) experienced seromas, 3 of these resolved spontaneously, one requiring image-guided drainage. Conclusion Incisional hernia repair using combination polypropylene and bio-absorbable mesh provides a safe and effective repair with low recurrence and incidence of surgical site occurrences in the short term. Longer follow up and further studies are needed to evaluate this mesh technique to support ongoing use of absorbable meshes in complex hernia repair.
