The direct Kugel Patch method is a minimally invasive but nonlaparoscopic preperitoneal method of hernia repair which has various ideal characteristics including all the benefits of laparoscopic hernia repair without the risks of complications. In this retrospective study, we report our experience with this method for adult inguinal hernia repair. Forty-four hernias, including 35 indirect, 7 direct inguinal hernias, and 1 recurrent indirect inguinal hernia, in 41 patients were surgically repaired using the direct Kugel patch method. The average operation time was 45.6 +/- 11.3 min, and the average hospitalization time was 6.2 +/- 5.0 days. There were 5 complications of seroma and only 1 recurrence of hernia which were successfully managed. We concluded that the direct Kugel patch method provides an ideal approach to adult inguinal hernia repair with short operation time and hospital stay and a very low risk of complications or recurrence.
