Thoracic versus abdominal approach to correct diaphragmatic eventration in children

The feasibility and safety of same-day surgery for diaphragmatic eventration by minithoracotomy in children

PURPOSE

The diaphragmatic plication procedure by thoracoscopy has gradually become standard treatment for diaphragmatic eventration (DE). However, thoracoscopic diaphragmatic plication is difficult to manipulate and the surgical learning curve is long. This study aimed to demonstrate the feasibility and safety of same-day surgery for DE by minithoracotomy in children.

METHODS

From December 2017 to December 2019, we included 22 patients who underwent diaphragmatic plication of DE in the Department of Pediatric Thoracic Surgery at the Guangzhou Women and Children's Medical Center. A total of 10 patients underwent diaphragmatic plication by minithoracotomy and 12 patients underwent thoracoscopic plication. The perioperative condition and postoperative follow-up were evaluated, respectively.

RESULTS

The age, sex, and weight were no different in the minithoracotomy group versus the thoracoscopy group (P > 0.05). The intraoperative time, blood loss volume, and postoperative hospital stay of the minithoracotomy group were significantly less than that of the thoracoscopy group (31.10 ± 4.70 min vs. 72.08 ± 22.8 min; 1.20 ± 0.42 ml vs. 2.58 ± 1.67 ml; and 1.00 ± 0.00 days vs. 6.00 ± 2.95 days, respectively, all P < 0.05). The eventration levels in these two groups were significantly different in the perioperative and postoperative periods as detected by chest X-ray. No chest tubes were inserted and no recurrence of DE occurred in the thoracoscopy group through the postoperative follow-up of at least 6 months.

CONCLUSION

Same-day surgery by minithoracotomy as a treatment for DE was feasible and safe with less operative time, less blood loss, and low recurrence. Same-day surgery for DE was attributed to a quick recovery. More prospective studies are necessary to further explore the consequences of same-day surgery for DE by minithoracotomy.

Comparative Study of Thoracoscopic and Modified Small Incision Repair for Congenital Diaphragmatic Eventration in Children

Background: Thoracoscopic diaphragmatic plication has gained popularity in the treatment of congenital diaphragmatic eventration (CDE), but the therapeutic effect and prognosis have rarely been compared with nonendoscopic surgery. Materials and Methods: The medical records of 77 children who had received treatment for CDE in our institution from September 2006 to January 2019 were retrospectively analyzed. According to the repair approach, the children were divided into a thoracoscopic plication group and a modified small incision plication group. The perioperative characteristics and follow-up details after diaphragm plication were compared between the two groups. Results: Among 77 children with CDE, 44 cases were in the thoracoscopic plication group and 33 cases were in the modified small incision plication group. All the cases of CDE were unilateral, with 13 cases on the left side and 64 cases on the right side. There were no differences in the preoperative characteristics between the two groups. The modified small incision plication group had a higher bleeding volume (P = .000) and a greater proportion of patients needing chest drainage (P = .000), whereas the differences in the total and postoperative hospital stays (P = .088, P = .247, respectively) did not significantly differ between the two groups. There were no differences in postoperative improvement in the location of the diaphragm between the two groups or between the right and left lesions (P = .438, P = .677, respectively). The total follow-up time was 2-11 years. No recurrence was reported during this period in either of the groups, but the incidence of postoperative thoracic deformities was higher in the modified small incision plication group (P = .013). Conclusions: Compared with the modified small incision plication, thoracoscopic plication has the advantages of smaller blood loss, a low percentage of intrathoracic drainage tube usage, and no occurrence of thoracic deformities.
