Abstract

Purpose: The purpose of this study was to determine if utilization of biologic mesh underlay during thoracoscopic congenital diaphragmatic hernia (CDH) primary repair (PR) results in reduced 5-year hernia recurrence rates. Methods: A retrospective review was completed for all primarily repaired CDH utilizing a thoracoscopic approach from January 1, 2003 to June 31, 2013. Patients were included in the study cohort if they had a thoracoscopic PR of their CDH without any mesh reinforcement or with biologic mesh underlay. Charts were then reviewed for no less than 5 years postoperatively for reports of clinical and/or radiographic hernia recurrence. The cumulative annual herniarecurrence as well as other demographic factors were analyzed. Results:Within the study period, 46 patients were identified that met study criteria. Three patients were lost to follow-up. Fifteen of the remaining patients (15/43: 34.9%) had a biologic underlay. Within the cohort, seven recurrences were noted within 5 years of the index procedure (7/43; 16.7%). Four recurrences occurred within the first postoperative year, and all occurred by the third postoperative year. One recurrence was in a patient with a biologic underlay at 4 months after repair. This was a clinically/radiographically silent 4 mm defect and noted at laparoscopy for another indication (1/15: 6.6%). The remainder occurred in primarily repaired patients without mesh reinforcement (6/28: 21.4%). Conclusions: Thoracoscopic PR of CDH can be successfully performed in select patients. The use of a biologic mesh underlay in this subset of patients appears to confer reduced hernia recurrence.
