Ventral hernias repair using combined open component separation technique with onlay polypropylene mesh

Authors

Abstract

Background
Ventral hernia repair with large defect represents a surgical challenge, as a classical repair has increased risk of compartmental syndrome and is associated with high rate of recurrence. The main indications of combined components separation technique with onlay polypropylene mesh are to avoid under-tension repair and thus avoid risk of complications.
Aim
To evaluate combined open component separation technique with onlay polypropylene mesh in repair of ventral hernia with large defect.
Patients and methods
This prospective study was carried out at the Gastrointestinal and Laparoscopic Surgery Unit, General Surgery Department, Tanta University, between December 2017 to May 2019 and included 40 patients who presented with ventral hernia with large defect.
Results
The study population included 35 females and five males, with a mean age of 42.54±6.27 years. The mean preoperative BMI was 35.65±2.63 kg/m. The mean operative time was 174.24±28.34 min, and the mean postoperative hospital stay was 4.12±2.1 days. Postoperative complications were encountered in 14 (35%) patients. No recurrence occurred with a mean follow-up of 24 months.
Conclusion
Combined open component separation technique with onlay polypropylene mesh reinforcement achieved strong, tensionless, and functional fascial closure in ventral hernias with large defect.
