Three-year outcome after anterior component separation repair of giant ventral hernias: A retrospective analysis of the original technique without mesh.

Introduction: In this study we presented our results with anterior component separation technique utilized in the repair of giant ventral hernias. Our primary endpoints were the rates of surgical site occurrences and recurrence at three years. Besides we investigated the impact of components separation repair on abdominal wall functions.

Methods: We retrospectively analyzed the prospectively-collected data of 40 patients that were operated on between April 2004 and February 2012 for their median ventral hernias sizing larger than 15 cm in width. Our inclusion criteria for component separation program excellently corresponded today's "giant ventral hernia" standards. The method used for components separation was identical to the original Ramirez technique, and did not comprise of any mesh reinforcement. The ICU stays, prolonged intubation, early and late complications, mortality and recurrences at three years were recorded. We used a curl-up test to demonstrate the amelioration of the abdominal wall functions postoperatively.

Results: The older age and larger defect size were the significant risk factors necessitating prolonged intensive care. Surgical site occurrences were recorded in 18 patients (45.0%). A total of 7 recurrences (17.5%) were detected at three years. Patients showed a significant improvement in raising their trunks after repair (p < 0.001).

Conclusions: Our findings demonstrated that components separation technique in the original form caused excessive wound complications including skin necrosis which in turn caused delayed discharge from the hospital. The 17.5% recurrence rate seemed higher than those of more recent papers. The already-established newer modifications should be integrated in the repair method. The components separation repair clearly improves abdominal wall functions.
