P-075 DURABLE REPAIR OF INCISIONAL HERNIA BASED ON BIOMECHANICAL PRINCIPLES – 3 YEAR FOLLOW UP

Abstract Aim Durable composite constructions of polymers follow specific mechanical principles. Incisional hernia can be repaired durably based on biomechanical How are the results after three years? Material and methods The biomechanics abdominal wall was analyzed ex vivo with cyclic loading common in material sciences. resulting GRIP concept clinically applied. tissue quality individual patient assessed computed tomography at rest during Valsalva's maneuver. All patients recieved single-shot antibiosis. Patients were discharged full ambulation achieved. Results A total 228 (120 males 108 females) treated for incisional hernia. Primary 166, recurrence 62 patients. had an average 1.3 risk factors most grouped as ASA III (n= 119). Emergency repairs necessary 11 Hernia orifices mostly median (N= 141) lateral (63 patients) 23 combined cases. sizes 9 ± 6 cm wide 13 8 long. mesh-defect area ratio 7.75. Fixation a 60 fixation points to reach adequate levels. 137 followed years so far. Four died follow-up (Follow-up rate 100%). One detected liver transplant reconstructed sandwich. Pain levels low (median NAS = 0 under load, u-test: p 0.07672). Conclusion
