Background
Incisional hernia repair is a common surgical procedure in surgical practice. In this study, we aimed to present our outcomes of Component Seperation Technique (CST) repair in patients with giant incisional hernia and compare the results of CST with polypropylene mesh (CS-M)or without mesh (CS).

Material and Methods
A comprehensive retrospective medical record review was performed on all patients who underwent the CST for incisional hernia at Mersin University Medical Faculty, Mersin, Turkey, between 2007 and 2013. 69 consecutive patients were included. Patient characteristics including demographic variables, postoperative complications, recurrence.

Results
A total of 69 patients were evaluated in this study, with 34 (49.3%) men and 35 (50.7%) women. There were no significant differences between the two groups in terms of BMI (CS vs. CS-M, 27.70 [21.30-31.20] vs. 25.51 [20.00-31.20], p=0.61), ASA score (2 [1-4] vs. 2 [1-3], p=0.55), and hernia defect size (314.00 [235.00-706.00] vs. 290.00 [62.00-940.00], p=0.10). The mean operating time was longer in CS group when compared with CS-M group (143.33 ± 38.19 vs. 115.57 ± 20.83, p=0.001). A total of two patients (11.1%) had recurrence hernia in CS group vs. four (7.8%) patients in CS-M group (<0,05).

Conclusion
Component seperation technique is a successful method for complex incisional hernia treatment. CS-M reduces recurrence rates.
