Aim: To determine the best way to perform diaphragmatic plication for diaphragmatic eventration (DE) using minimally invasive surgery. Materials and Methods: We conducted a retrospective review of pediatric cases of DE treated between 2007 and 2012. Thoracoscopic plication (TP) is performed using single-lung ventilation with three 5-mm ports; laparoscopic plication (LP) is performed using three or four 5-mm ports. The choice of technique was determined preferentially by the treating surgeon. Results: There were 20 subjects (13 treated by LP and 7 treated by TP). Etiology of DE was phrenic nerve injury (LP, n=11; TP, n=1) and muscular deficiency (LP, n=2; TP, n=6). Mean age (LP, 18 months; TP, 25 months) and weight (LP, 8.0?kg; TP, 9.7?kg) at surgery were not significantly different. Mean operating time was 155.6 minutes in LP and 167.0 minutes in TP (P=not significant). Mean intraoperative end-tidal CO2 was 41.9?mm Hg (range, 35-52?mm Hg) in LP and 36.9?mm Hg (range, 33-41?mm Hg) in TP (P=.01). Mean duration of postoperative ventilation was 1.2 days in LP and 1.3 days in TP (P=not significant). Mean time taken to recommence feeding postoperatively was 1.6 days in both groups (P=not significant). Complications were one conversion to thoracotomy in TP, 1 case of atelectasis in each group (P=not significant), and 6 cases of recurrence in LP versus none in TP (P=.04). Conclusions: Both TP and LP are beneficial for treating small children with DE. However, there is a higher incidence of recurrence after LP, and the role of TP in cardiac patients requiring subsequent surgery is debatable.
