We aimed to evaluate the long-term recurrence rate as well as surgical complications in patients operated with onlay mesh repair technique for incisional hernia. Material and Method: We studied a serial of 139 patients retrospectively, operated due to incisional hernia in between January 2001 to November 2009 in Vakıf Gureba Training and Research Hospital General Surgery Department. The patient's age, sex, location and size of the defect, operation findings, duration of hospitalization, early and late complications and recurrences were recorded. Result: There were 56 men and 83 women in our serial. The mean age was 55 (age range, 30-85 years). The most common incisions that hernia had been developed were upper midline incision (51 patients) and lower midline incision (37 patients). The size of the hernia defect was 0-5 cm in 118 patients , 6-10 cm in 5 patients 11-15 cm in 12 patients, and above 15 cm in 4 patients. The postoperative complications were wound infection in 22 patients, seroma in 12 patients. The mean duration of hospital stay was 4.53 (range 1-10 days). The recurrence was detected in 6 patients. Discussion: It seems to be that onlay mesh repair is safe and effective technique for incisional hernia repair.
