What This Answer Covers

1. Introduction & Embryology - Common foregut origin, tracheoesophageal septum formation, Sonic Hedgehog signalling, Adriamycin model
2. Classification - Both the Gross classification (A-E) and Vogt classification (2, 3A, 3B, 3C) with a detailed comparison table - with actual diagrams from Scott-Brown's (Vol 2) and Schwartz's Surgery
3. Associated Anomalies - Full VACTERL and CHARGE associations
4. Clinical Features - Antenatal (polyhydramnios, absent stomach bubble) and postnatal (3 C's: Choking, Coughing, Cyanosis), with H-type delayed presentation highlighted for ENT relevance
5. Diagnosis - NG tube test, X-ray findings, pull-back oesophagogram for H-type, bronchoscopy, echocardiography, prenatal MRI
6. Spitz Risk Stratification - Groups I, II, III with survival rates (replacing Waterston)
7. Pre-operative Management - Replogle tube, head elevation, avoiding PPV, preoperative bronchoscopy
8. Surgical Management with flowcharts - Standard repair (extrapleural thoracotomy + thoracoscopic), long-gap OA (Foker technique, oesophageal replacement), H-type cervical repair, premature infant staged approach
9. Post-operative Care - Trans-anastomotic feeds, contrast study, GERD prophylaxis
10. Complications - Anastomotic leak, stricture, recurrent TEF, tracheomalacia, GERD, eosinophilic oesophagitis - with management flowchart
11. Recent Advances - Thoracoscopic near-infrared guided H-type repair (2026), endoscopic fibrin glue/TCA/OTSC, bioengineered oesophageal scaffolds
