Abstract
PURPOSE: Congenital diaphragm anomalies, including eventration, Morgagni diaphragmatic hernias (M-CDH), and Bochdalek diaphragmatic hernias (B-CDH), have been successfully repaired by using minimally invasive surgery (MIS). However, some reports have shown a high recurrence rate for some defects, potentially due to difficulty associated with the rigid instruments. Robotic surgery may help close diaphragmatic anomalies more effectively. In this paper, we present a series of 8 consecutive patients with diaphragmatic anomalies who underwent robotic repair. METHODS: We retrospectively reviewed patients with diaphragmatic anomalies. There were 2 patients with eventration, 5 with B-CDH, and 1 with M-CDH. All procedures were performed by using the Standard Da Vinci surgical robot (Intuitive Surgical, Sunnyvale, CA) with one camera arm (5-mm two-dimensional scope) and two instrument arms (5 mm). RESULTS: Average age was 3.9 months (4 days to 12 months). Average weight was 3.6 kg (range, 2.2-10.5). Four B-CDH patients were approached through the chest and 1 from the abdomen. The patient with M-CDH had an abdominal repair, and both eventrations were performed from the chest. One B-CDH and 1 eventration were converted to thoracoscopic procedures. Average operative time was 1 hour and 20 minutes. One recurrence developed in a relatively large B-CDH repair that was closed primarily. Average follow-up was 20 months. CONCLUSIONS: Robotic surgery is safe and effective for repairing diaphragm anomalies in small children. Although we prefer the thoracic approach for repairing the B-CDH, occasionally smaller newborns-perhaps those less than 2.5 kg-may do better with the abdominal approach, since the articulating instruments requiring a significant length in order to maneuver.
