Role of hiatal hernia in delaying acid clearance

Hiatal hernia in pediatric gastroesophageal reflux

BACKGROUND

This study compares esophageal pH-monitoring parameters of children with gastroesophageal reflux (GER) with or without hiatal hernia (HH) and determines the outcome of those with GER and HH.

METHODS

Among 718 children with GER, 45 children (6%) with associated HH were retrospectively studied. They were divided into those with neurologically normal development (NN, n = 35) and those with neurologic disorders (ND, n = 10). The pH-monitoring parameters of 27 of these (60%) were compared with pH-monitoring parameters of 27 control children who had GER without HH.

RESULTS

Esophageal clearance was longer in patients with HH compared with those without HH (P < 0.05). All 35 NN patients underwent a trial of conservative treatment, which failed in 9 patients (25.7%). Surgery was the initial treatment in 8 ND patients. Follow-up was available in 20 NN and 10 ND patients. Nine of 11 conservatively treated NN patients improved. All NN (n = 9) and ND (n = 8) patients who underwent surgery improved. Conservative treatment failed in 2 NN and in 2 ND patients.

CONCLUSIONS

Presence of HH in children with GER is associated with prolonged exposure of the esophagus to acid and a high failure rate of nonoperative treatment. However, medical treatment should be tried in NN children despite the significant failure rate.

Twenty to 40 year follow up of infantile hiatal hernia

The aim of this study was to assess clinical and radiological findings of gastro-oesophageal reflux in adults who were diagnosed as having a hiatal hernia in infancy or early childhood. One hundred and eighteen patients with a minimum age of 20 who were diagnosed as having a hiatal hernia in childhood were interviewed; barium meal examination was performed in 96 of these cases. Ninety four patients had not required surgery for their hernia. The hiatal hernia persisted in 53% of these patients and 46% experienced heartburn at least monthly but in only three was this severe. Heartburn was significantly more common in patients in whom reflux was seen on barium meal. The consumption of antacids was significantly lower (20% v 46%) in patients who responded well to treatment as children. Eighteen of 24 patients who underwent surgery as children experienced heart-burn monthly but in only one patient was this severe. Two patients underwent endoscopy at their request because of symptoms during this follow up. Both had Barrett's oesophagus. In conclusion, despite the persistence of the hiatal hernia in half of the non-surgically treated patients, few complained of significant symptoms. Effective treatment in childhood was associated with a significant reduction in antacid consumption for heartburn as adults. The finding of Barrett's oesophagus in two patients high-lights a possible role for endoscopic screening in this patient group.
