Insights
Diaphragmatic plication effectively treats symptomatic eventration of the diaphragm (ED) in children, restoring normal diaphragm position and resolving respiratory issues. Post-surgery, patients experienced symptom remission with no relapse observed.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Respiratory Medicine
Background:
- Eventration of the diaphragm (ED) involves abnormal diaphragm elevation, potentially causing respiratory distress in children.
- Symptomatic congenital or acquired ED often necessitates surgical intervention.
Purpose of the Study:
- To evaluate the outcomes of diaphragmatic plication in pediatric patients with unilateral ED.
- To assess the efficacy of surgical correction for symptomatic diaphragm elevation.
Main Methods:
- Retrospective review of 15 children who underwent diaphragmatic plication for ED between 1997 and 2003.
- Diagnosis confirmed via chest radiography and fluoroscopy; surgery pursued for non-operative treatment failures.
- Post-operative diaphragmatic function assessed using fluoroscopy in 9 patients.
Main Results:
- Diaphragmatic plication normalized diaphragm position in 14 of 15 patients.
- Respiratory symptoms like tachypnea and pneumonia resolved post-surgery.
- Post-operative fluoroscopy confirmed immobile diaphragms without paradoxical motion in evaluated patients.
Conclusions:
- Diaphragmatic plication is an effective surgical treatment for symptomatic unilateral ED in children.
- The procedure restores normal diaphragm location and function, leading to symptom remission.
- Long-term follow-up showed no symptom relapse in patients with immobile diaphragms post-plication.
Objective:
Eventration of the diaphragm (ED) is defined as the abnormal elevation of the diaphragm. Although asymptomatic ED may be amenable to conservative treatment, symptomatic ED in children, either congenital or acquired, may require surgical treatment. This study evaluated the results of diaphragmatic plication in children with unilateral ED.
Methods:
Fifteen patients who had undergone diaphragmatic plication for ED between 1997 and 2003 were evaluated retrospectively. The diagnosis of ED was established by routine chest radiographs and fluoroscopy. Patients who failed to respond to nonoperative treatment were referred for surgery. Nine patients underwent diaphragmatic fluoroscopy 1-5 years following plication to assess function.
Results:
Indications for diaphragmatic plication were respiratory symptoms such as tachypnoea, dyspnoea, recurrent pneumonia and failure to thrive. In 14 patients, the position of the diaphragm was normal after plication, but the diaphragm was elevated without symptoms in one patient during postoperative follow-up. The motion of the diaphragm was investigated in nine patients. Fluoroscopic studies showed that the operated hemidiaphragm was immobile and there was no paradoxical motion. No return of symptoms was found during follow-up.
Conclusion:
ED is the abnormal elevation of the diaphragm as a result of paralysis or aplasia of the muscular fibres. The abnormally elevated diaphragm may compress the ipsilateral lung, and with respiratory effort the mediastinum may shift towards the normal side. Therefore, diaphragmatic plication is performed to restore normal pulmonary parenchymal volume by replacing the diaphragm in its normal location. After plication, there was immediate remission of symptoms in most patients and decreasing symptoms were observed for a year in others. During follow-up, the location of the diaphragm was normal and no paradoxical movement was observed. Relapse of symptoms was not noted in patients with immobile diaphragms.
