Insights
Preventive fundoplication in infants with congenital diaphragmatic hernia (CDH) significantly reduced gastroesophageal reflux (GER) but did not impact nutritional outcomes. This suggests selective use in specific CDH cases.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Neonatal Care
Background:
- Gastroesophageal reflux (GER) is a common complication in children with congenital diaphragmatic hernia (CDH).
- Optimal management strategies for GER in CDH patients remain unclear.
- This study investigates the impact of preventive fundoplication during initial CDH repair.
Purpose of the Study:
- To evaluate the efficacy of a preventive fundoplication in reducing GER and nutritional morbidity in infants with left CDH.
- To determine if performing fundoplication during the initial surgery improves outcomes for CDH patients.
Main Methods:
- A retrospective study comparing 17 patients with preventive fundoplication (Group A) and 19 patients without (Group B).
- Patients were classified by disease severity (mild, intermediate, severe) based on liver position and need for patch repair.
- Clinical data were analyzed with a mean follow-up of 3 years.
Main Results:
- The incidence of GER was significantly lower in Group A (17.6%) compared to Group B (52.6%) at 1-year follow-up (p < 0.5).
- Group B patients had a higher rate of requiring fundoplication before 6 months (30%).
- No significant differences were observed in hospitalization duration, need for nutritional supplementation, gastrostomy, or growth retardation between the groups.
Conclusions:
- Adding antireflux surgery to left CDH repair is recommended only for patients with intrathoracic liver and/or requiring patch repair.
- Selective use of fundoplication may be beneficial for specific subgroups of CDH patients.
Background:
Gastroesophageal reflux (GER) is common in children with congenital diaphragmatic hernia (CDH), and the optimal management in these patients is not well established. The aim of this study was to assess whether a preventive fundoplication performed during the first surgery will improve GER and nutritional morbidity in patients with a left CDH.
Methods:
Thus we studied one group of 17 patients treated with a one-step antireflux procedure (group A) and a group of 19 patients with only initial diaphragmatic repair (group B) between January 1994 and December 2004. The patients were classified in three stages, mild intermediate and severe form, based on anatomic criteria (liver position and patch requirement). Most of the patients with the severe form of disease were in group A. Clinical charts were compared between the two groups with a mean follow-up of 3 years.
Results:
For patients with intra-abdominal liver and direct diaphragmatic closure, the duration of hospitalization was significantly longer in group A than in group B (p = 0.08). The incidence of GER was significantly lower in group A (17.6%) than in group B (52.6%) at 1-year follow-up (p < 0.5). In the last group, 30% required a fundoplication before 6 months. Seven patients (19%) required intermittent nutritional supplementation via nasogastric tube feeding; for these patients there was no difference between the two groups. A gastrostomy was performed in only one patient. Twelve percent of patients had growth retardation during most of their first year, again with no difference between the two groups.
Conclusions:
Based on the published data, recommendations can be made regarding the efficacy of adding an antireflux surgery procedure to left CDH repair in only patients with intrathoracic liver and/or patch requirement.
