Research summary
Oesophageal atresia (OA) is the most common congenital anomaly of the oesophagus (gullet). There is interruption of the continuity of the oesophagus, with or without an abnormal communication with the trachea (windpipe) called a tracheo-oesophageal fistula (TOF). Once incompatible with life, it is now a congenital anomaly with overall survival rates > 90%. This reflects significant developments in surgical techniques and in neonatal care since the 1940s.
All children with OA and/or TOF need surgical repair to restore continuity of the oesophagus allowing them to eat and drink normally.
Only types C and D have a connection (fistula) from the distal (lower) end of the oesophagus to the trachea called a distal tracheo-oesophageal fistula (dTOF).
Initial management of any baby with suspected oesophageal atresia involves placing a replogle tube to drain saliva from the upper blind ending oesophageal pouch and prevent overspill into the lungs. This is usually removed during surgery.
Surgical repair involves dissecting the fistula off the trachea and closing the resulting defect. The fistula is then joined to the upper atretic oesophageal pouch to create an oesophagus which is in continuity. A naso-gastric tube is passed from the nose down into the stomach
This is a major thoracic procedure and complications include a leak from the anastomosis in 15% of patients; stricture (narrowing) in 30% and recurrent TOF in 10%.
A leak can be a mild problem which seals spontaneously with non-operative management, to a severe problem requiring multiple operations, a prolonged stay in intensive care and hospital with short, medium and long-term problems. Sometimes the oesophagus has to be abandoned and replaced. Rarely death can occur.
This study aims to see if a full randomised trail is feasible to see if indocyanine green(ICG) and near infrared fluorescence(NIRF) can predict or prevent patients developing an anastomotic leak or strictureREC name
