Background: Thoracoscopic plication has gained popularity in the management of diaphragmatic eventration, and several suturing techniques have been described. However, the superiority of one technique over the other has not been demonstrated. The purpose of this study is to report our experience with diaphragmatic plication and to compare the thoracoscopic interrupted and pleated suture techniques in pediatric patients with diaphragmatic eventration.
Methods: This is a retrospective cohort study (level of evidence: 3) performed on 14 patients with diaphragmatic eventration. All patients were symptomatic and had diaphragmatic plication via thoracoscopy. The patients were further divided into two groups according to the repair technique; interrupted repair (n = 9) and pleated repair (n = 5). Preoperative, operative and postoperative data were compared between the two groups.
Results: The median age was 9.5 months (25th- 75th percentiles: 6 to 15 months), and 8 (57%) were males. Twelve patients (85.71%) had right side eventration, and nine patients (64.29%) had congenital diaphragmatic eventration. One case was converted to open thoracotomy because of adhesions. There was no difference in the preoperative characteristics between both groups. Median operative time was 117 min (25th- 75th percentiles: 101-129 min) and 77 min (25th- 75th percentiles: 73-83 min) in the interrupted and pleated groups, respectively (p = 0.004). One patient had a postoperative elevation of the diaphragm (incomplete repair) in the pleated group (p = 0.357). No recurrence was reported during the follow-up.
Conclusion: Thoracoscopic plication is an effective technique for management of diaphragmatic eventration in children. Pleating technique is easy, fast, and associated with a marked reduction in operative time.
Type of the study: Retrospective cohort study.
Levels of evidence: Level of evidence: 3.
