Event or Problem Description
The following literature publication was reviewed: ¿maximizing mesh mileage: evaluating the long-term performance of a novel hybrid mesh for ventral hernia repair,¿ hernia, pp.1¿9.Spurzem, g.J.Et al.(2024) maximizing mesh mileage: evaluating the long-term performance of a novel hybrid mesh for ventral hernia repair doi: 10.1007/s10029-024-02995-0.This retrospective, single-center case review analyzed outcomes in 278 predominantly male patients with a mean age of 57.8 years who underwent ventral hernia repair (vhr) with gore synecor from may 2016 to december 2022.Primary outcomes were hernia recurrence and mesh infection rates.Secondary outcomes were 30-day morbidity, 30-day mortality, 30-day readmission, re-operation, surgical-site infection (ssi) and occurrence (sso) rates, and occurrences requiring intervention (ssoi).Procedures were accomplished through open approach, robotically, and laparoscopically.Mean hernia defect size was 63.4 cm2, with a mean length of 7.9 cm and mean width of 6.0 cm.93.2% of cases were clean and 37.8% required component separation.Mesh was most commonly placed intraperitoneal (41.4%), followed by retrorectus (28.8%), preperitoneal (19.8%), onlay (9.7%), and as a bridge in 1 case (0.36%) patient outcomes included 14 cases of hernia recurrence and 4 cases of mesh infection.All cases of mesh infection were managed with systemic antibiotics plus either percutaneous or operative drainage with partial mesh debridement.One case involved an open vhr with ol mesh and concurrent enter cutaneous fistula (ecf) takedown in a contaminated operative field that then developed abdominal wound dehiscence with exposed mesh 26 days after the initial operation.Another case involved a rives-stoppa repair with adjacent tissue transfer for large soft tissue defect coverage and subsequent seroma formation that underwent drainage by interventional radiology.The patient then developed a persistent draining sinus tract that was found to involve the mesh.Open debridement was performed 539 days after the initial operation.The remaining 2 cases of mesh infection involved large open incisional hernia repairs with adjacent tissue transfer that then developed abdominal wall abscesses communicating with the mesh.One case was managed with operative drainage and partial mesh debridement, and the other with percutaneous drainage.All cases of mesh infection resolved with these measures and did not require full mesh explanation.There was a single 30-day mortality in the study population involving a comorbid patient who underwent large open ventral hernia repair and subsequently developed bowel ischemia and abdominal compartment syndrome.17 patients experienced surgical site infections.8 patients experienced reinterventions.13 patients experienced seromas and 4 experienced hematomas.This case involved abdominal wall abscess involving mesh, mesh infection with an open ventral hernia repair, acs/eor, panniculectomy.
