P-047 REDUCING THE RISK OF MESH EROSION IN A MODIFIED RETROMUSCULAR SUGARBAKER TECHNIQUE FOR PARASTOMAL HERNIA REPAIR

Abstract

Abstract Aim Modified retromuscular Sugarbaker procedure (SP) is a promising approach for parastomal hernia repair. However, its potential complications, including the risk of mesh erosion, encourages us to develop other techniques of mesh placement. We propose an addition to this parastomal retromuscular mesh reinforcement. Materials and Methods We present the case of a 53 year old-woman, with a history of proctocolectomy with end ileostomy due to anal adenocarcinoma, undergoing emergency surgery due to parastomal hernia incarceration. Sugarbaker repair was performed placing inlay composite mesh fixed with reabsorbable tackers. Subsequently, the patient was admitted for recurrent parastomal hernia and midline ventral hernia surgery. Results We performed a modified retromuscular SP as described by Pauli in 2016. After midline laparotomy, hernia content was reduced and extensive retromuscular dissection with transversus abdominis release (TAR) performed, placing a wide retromuscular polypropylene mesh prior to closing parastomal fascial defect. Stoma was parietalized from lateral to medial in an S-shaped configuration. We placed a segment of bioabsorbable mesh covering the parietalized stoma to avoid direct contact with the polypropylene mesh. No recurrence was detected 3 months after surgery, pending reassessment at 6 months. Conclusions This repair provides the benefits of an open posterior component separation with TAR, maintaining the biomechanics of a functional abdominal wall, whilst offering the advantages of mesh reinforcement in a modified Sugarbaker configuration. Our experience with this novel technique seems promising. Rate of mesh erosion is yet to be defined and requires long-term studies before widespread adoption, with special concern on mesh placement.
