Surgical complications, especially gastroesophageal reflux disease, intestinal adhesion obstruction, and diaphragmatic hernia recurrence, are major sequelae in survivors of congenital diaphragmatic hernia

Abstract

Purpose: This study aimed to characterize the surgical complications, especially gastroesophageal reflux disease (GERD), intestinal adhesion obstruction (IAO), and diaphragmatic hernia recurrence, in patients with congenital diaphragmatic hernia (CDH).

Methods: Between January 1995 and December 2013, we determined the incidence of surgical complications and their predictors in CDH patients. We also examined whether the CDH repair and patch closure were associated with the incidence of IAO and the severity of adhesion.

Results: Seventy-four CDH survivors were evaluated. GERD occurred in 28 patients (37.8%) and recurred in 8 patients (10.8%). Stomach herniation was a risk factor for GERD, and occurred in 25 patients. IAO occurred in 13 patients (17.6%). In 240 neonatal laparotomies in the same period, the incidence of IAO was significantly higher in patients who underwent CDH repair than in patients who underwent other neonatal laparotomy (p = 0.023). Surgical time and intraoperative bleeding were significantly greater following CDH repair with an artificial patch compared with CDH repair with direct closure.

Conclusion: Surgical complications are major sequelae in survivors of CDH repair. CDH repair and artificial patch closure were significantly associated with the incidence of IAO and the severity of adhesion.
