[Morgagni-Larrey anterior diaphragmatic hernias. Review of 13 cases].

Abstract

OBJECTIVE:

A review of anterior congenital diaphragmatic hernias (CDH) treated at our center, analysis of our experience and evolution in the surgical technique in pediatric patients over the last 15 years.

MATERIAL AND METHODS:

A retrospective descriptive study of patients of our center with anterior CDH (Morgagni, Larrey and Morgagni-Larrey) between 2000 and 2015, through a systematic review of clinical records. The studied variables were: age at diagnosis, age at treatment, diagnostic methods, symptoms, surgical technique, evolution, complications and relapses. Posterior CDH (Bochdalek) and patients older than 14 years old were excluded.

RESULTS:

13 patients (8 females) with anterior diaphragmatic hernia. Mean age at diagnosis was 29.4 months (range fetal age 4 months-14 years old) and mean age at surgery 18.5 m (range 1 day-14 years). Three left hernias (Larrey hernia) and n= 2central hernias (Morgagni-Larrey). Two patients were diagnosed prenatally, the rest of them were casual diagnoses. Symptoms: n= 6 asymptomatic, n= 4respiratory symptoms, n= 1abdominal pain, n= 1both symptoms and n= 1 hydrops fetalis. In all cases, a chest X-ray was performed, CT in n= 5 cases and US in other n= 5 patients. The surgical approach was laparoscopic in n= 7 (1 conversion due to bleeding), thoracoscopic in n= 1 (requiring conversion to laparotomy due to technical difficulty), thoracotomy in n= 1patients and laparotomy in n= 4. Prosthetic patches were necessary in n= 2 patients. During the follow-up (3.9 years, range: 1-8), there were n= 2 recurrences (laparoscopy and thoracotomy) and n= 1 exitus 2 years after surgery, due to pathology not associated with diaphragmatic hernia.

CONCLUSIONS:

The minimally invasive approach is considered of choice in the literature. Our group considers that most patients with anterior CDH should be considered for a laparoscopic repair. The laparoscopic approach is easily reproducible and the conversion rate is low when it is performed by expert surgeons. However, the low prevalence of this pathology would require comparative and long-term multicenter studies to obtain statistically significant conclusions.
