Efficacy of Partial Wrap Fundoplication for Gastroesophageal Reflux After Repair of Esophageal Atresia.

Gastroesophageal reflux (GER) often develops in children who have undergone prior repair of esophageal atresia/tracheoesophageal fistula (EA/TEF). Fundoplication is necessary in many of these children. The complete wrap (Nissen) fundoplication is often used in this setting. However, poor results have been noted, with a mean failure rate of 30% reported in four recent studies. A partial wrap fundoplication for GER associated with EA/TEF is theoretically attractive, because the poor esophageal motility and diminished acid clearance (already physiologically present) is exacerbated by a complete wrap fundoplication. The authors reviewed their extensive experience with partial wrap (Thal) fundoplication in EA/TEF to determine if the failure rate was better than that reported for the Nissen fundoplication. In the past 18 years, the authors performed 1,467 fundoplication procedures. During the same period, 143 children underwent repair of EA/TEF. Fifty-nine children underwent fundoplication after a previous EA/TEF repair. Most of the fundoplications (58 of 59, 98%) were Thal procedures. Defining failure strictly as a need for reoperation, the failure rate in our series was 15% (9 of 59 children). Compared with the failure rate in the 1,408 non-EA/TEF patients (61 of 1408, 4.3%), results were significantly worse for the EA/TEF group (P \u3e .001). The failure rate of Thal fundoplication performed for GER in the EA/TEF population is substantially higher than the non-EA/TEF patients. The same factors responsible for the development of reflux in these children (poor acid clearance, altered motility, esophageal shortening) may contribute to the higher failure rate. Although partial wrap fundoplication frequently failed (15%), the results were still substantially better than those reported for Nissen fundoplication in these children (30% failure rate)
