Bronchoscopy in newborns with esophageal atresia.

The aim was to evaluate the influence of rigid laryngotracheo-bronchoscopy in newborns with oesophageal atresia (OA) and tracheoesophageal fistula (TOF) in preventing complications, improving diagnosis and surgical treatment. Among 76 consecutive newborns, received in the Paediatric Intensive Care Unit (PICU) from January 1990 to September 2001 with prenatal o perinatal suspected OA, forty-five had one or more other congenital anomalies. They were divided in I Montreal's risk group for 73.7% (56) and in the II one for 26.3% (20). Endoscopic procedure was performed in the operating room with Storz's rigid ventilating bronchoscope just before surgery, in all babies. With bronchoscopic examination we were able to identify the level, number and size of TOF and to visualise anatomical variants in 76 children. 15 children with OA had a gasless abdomen, but an upper pouch fistula was found only in three cases. In another four cases bronchoscopy confirmed the diagnosis of an "H" fistula and cervical surgical approach was established. One case had only oesophageal stenosis. 56 patients had fistula in lower pouch and in the last 38 cases we proceeded with selective transtracheal fistula incannulation and then we provided gastric drainage. One quadriforcation, 2 triforcations, 3 aberrant right upper lobe bronchi, 1 congential subglottic stenosis and 1 associated with a congenital subglottic stenosis and 1 left main bronchus agenesia were detected. No complications were correlated to the procedure and no babies had early pneumonia. Continuous feeding was achieved in 70 out of 76 patients: 46 primary anastomosis with 12 staged repairs (OA I and II type long gap), 4 resections of TEF, 8 oesophagocoloplasty. Nine babies (11.8%) did not survive. Clinical follow-up was possible in all the survivors. Mortality rate in the high-risk patients with OA remains high because of the many complications that may occur. Tracheal endoscopy is useful in improving the diagnostic approach and to prevent pulmonary complications. Fistula incannulation minimizes the risk of gastric distension and its detrimental effect on ventilation, helping the surgeon to identify TEF easily and quickly. Moreover, the endoscopic approach offers obvious advantages for the anaesthesiologist and the surgeon and has proven, in our experience, to be effective.
