Anterior diaphragmatic hernias in children: long-term surgical outcomes
Anterior diaphragmatic hernia (ADH) is a rare congenital pathology that occurs in children with a frequency of 1:4800 (1–6% of all congenital diaphragmatic hernias). There are many controversial aspects in the surgical treatment of patients with ADH: the choice of surgical approach, the method of diaphragmatic repair and the feasibility of excision of the hernial sac. Objective. To conduct a comparative analysis of the surgical treatment of patients with ADH in different clinics, assessing longterm outcomes. Patients and methods. The medical records of 7 children with ADH who underwent surgical repair in different clinics (in time period from 2009 to 2019) were retrospecively reviewed. Evaluating the long-term results of ADH repair was made by telephone and online surveys of the parents of patients and by outpatient examination of children (chest x-ray in two projections). Results. In a ten-year period, 7 patients (4 boys and 3 girls) were operated on with a diagnosis of “anterior diaphragmatic hernia” at the age of 3 months to 12 years. In most children, a hernia was discovered accidentally by chest x-ray. Laparoscopic correction was performed in 5 (71%) cases, thoracoscopic correction – in 2 cases (29%). The main difference in surgical tactics in ADH patients was the manipulation with the hernial sac – the hernial sac was excised in 4 (57%) patients, but it was left in three cases (43%). The defect closure was performed by “full-thickness” separated sutures that fix the diaphragm to the anterior abdominal wall during laparoscopy (5) and to the chest tissue during thoracoscopy (2); in some cases, additional fixation to the rib (4) was performed. Sutures were tied extracorporeally and buried in the subcutaneous layer in 6 (86%) patients. Average follow-up was 7 years. While evaluating long-term outcomes no ADH recurrence were found. Conclusions. There are still many controversial aspects in the surgical treatment of ADH patients. In our opinion, multicenter studies with complex analysis of long-term results are required to standardize the surgical treatment of such patients.
