What the experts said
At Great Ormond Street, patients are fed by day 3-4 after TEF repair without routine contrast studies or chest tubes
Minor leaks after TEF repair are of no consequence and will heal without intervention
At Minnesota, routine contrast studies are not obtained for easy type C cases, but difficult cases get day 14 contrast to check for reflux
Type C TEF patients almost always have reflux
The decision to obtain contrast study with large or tension pneumothorax depends on distinguishing complete dehiscence from manageable leak
With large or tension pneumothorax, exploration may reveal a single loose stitch that can be repaired with one additional suture
Early re-exploration (days 3-6) for leak can result in esophageal loss because the esophagus is edematous and inflamed, appearing like 'Hamburg'
Dehiscence usually occurs in the first 48 hours
Indications for operative exploration are a very sick baby or contrast showing complete disruption
Once an esophagostomy is performed, the esophagus is lost in most cases
With complete disruption, the main priority is to save the patient's life by abandoning the esophagus
Major reasons for anastomotic disruption are tension or poor vascularization
Re-doing the anastomosis after disruption faces the same problems of tension and poor vascularization as the initial repair
For a sick baby with complete disruption, esophagostomy should be placed on the right side where the surgeon is already operating
For a more stable baby, left-sided esophagostomy is preferred because replacement operation into the left neck is easier
The distal esophagus should be taken down low and closed in 2-3 layers, not merely tied off, to prevent recurrent fistula formation
If a leak cannot be detected on esophagram but the patient is managed conservatively, the inability to detect it does not matter because management would not change
For a medium leak with evidence of infection but cardiovascular stability, placing a chest tube and administering antibiotics while observing is appropriate management
The concern with leaks is hemodynamic instability and sepsis, not the leak itself
One case required thoracoscopic repair of persistent leak at two weeks with pleural flap coverage
Leaving a drain at the time of initial operation provides insurance against leaks and avoids later manipulation to place one
If leak rate is less than 10%, routine drainage means draining 90% of patients unnecessarily
Drains sitting against the anastomosis may cause leaks, so they must be anchored 1-2 cm away
Chest drains often fail to drain contained leaks even when leaks are present on contrast studies
When a drain fails to drain a leak, interventional radiology can place a drain into the leaking area
If contrast study shows half going down and half into chest in a stable baby, the consensus is to do nothing
