Antireflux surgery in children suffering from reflux-associated respiratory diseases

The aim of our study was to evaluate the success, complications, and morbidity following a modified That fundoplication in children with reflux-associated respiratory disease (RARD). We used a procedure consisting of retroesophageal hiatal plasty, wrapping the gastric fundus around the gastroesophageal junction 180 degrees, and fixation of the lesser curvature at the abdominal wall. Follow-up by questionnaire of 128 (77 male, 51 females) out of 196 antireflux procedures between 1992 and 1995 was achieved. Surgical therapy was considered justified whenever there was gastroesophageal reflux resulting in severe recurrent respiratory symptoms. Eleven percent of the children suffered from bronchiectasis. The diagnosis of RARD was based on a high index of suspicion, barium swallow with fluoroscopy, 24-hr two-level pH-monitoring, bronchoscopy, bronchoalveolar lavage and detection of lipid-laden alveolar macrophages, esophago-gastroscopy, and esophageal biopsy. Patients with bronchopulmonary diseases such as allergy, immunodeficiency, cystic fibrosis, primary ciliary dyskinesia, and malformation of the bronchial tree or vessels had been excluded. "Evident improvement" as a result of surgery was reported in 88%, "no change" in 10%, and a "change for the worse" in 2% of patients. Persistent mild difficulties in swallowing were observed in 11%. Paraesophageal hernia, gas-bloat syndrome, and dumping syndrome were not observed. Two children needed a second operation because of relapse. The use of emergency steroidal medication for acute respiratory distress decreased impressively (219 single doses/year before surgery vs. 30 single doses/year after surgery). The need for more than 4 times/year of antibiotic therapy before surgery was reduced from 52.3% before to 14% after surgery. Most (90.6%) of the parents stated they would agree to have surgery done again ii medically indicated. In conclusion, Thal fundoplication is sufficient, safe, and effective in the management of RARD. Complications of the procedure were minor and of little consequence to the patient. Pediatr Pulmonol. 1999; 28:89-93. (C) 1999 Wiley-Liss, Inc.
