[Respiratory and swallowing difficulties after oesophageal atresia (author's transl)]
Insights
Persistent or recurrent tracheo-oesophageal fistulas are common after surgery for oesophageal atresia. Prompt diagnosis using radiography and endoscopy is crucial for managing associated respiratory and swallowing issues in infants.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Otolaryngology
Context:
- Oesophageal atresia repair can lead to persistent or recurrent tracheo-oesophageal fistulas.
- These fistulas cause significant respiratory and swallowing problems in infants.
- Associated anomalies like stenosis, reflux, and laryngeal/tracheal issues complicate management.
Purpose:
- To highlight the challenges in diagnosing and managing tracheo-oesophageal fistulas post-surgery.
- To emphasize the importance of thorough investigation for recurrent respiratory and swallowing difficulties.
- To present diagnostic techniques, including radiography and endoscopy, for fistula detection.
Summary:
- Tracheo-oesophageal fistula (TOF) is a primary cause of post-operative issues in oesophageal atresia, seen in 7/19 infants.
- Functional problems stem from TOF, stenosis, reflux, and other laryngo-tracheal anomalies.
- Radiography and detailed endoscopy are vital; repeated investigations may be necessary. Associated anomalies require consideration.
Impact:
- Improved diagnostic accuracy for tracheo-oesophageal fistulas.
- Enhanced management strategies for infants with post-operative complications.
- Better understanding of the multifactorial nature of functional problems after oesophageal atresia repair.
Abstract:
The main reason for these problems is a tracheo-oesophageal fistula, either recurrence of the T.O. fistula, either persistance of a fistula which has been neglected during surgery. It has been observed in 7 infants from 19 operated atresias with such problems. These functionnal troubles may be produced by different other anomalies: oesophageal stenosis and or dyskinesia often observed, gastro-oesophageal reflux, associated anomalies of the larynx or trachea; laryngeal paralysis, tracheomalacia, tracheal epithelium metaplasia, tracheal compression by abnormal vessel, neurological dysmaturity, loss of swallowing reflex after a long postoperative course. Radiography and endoscopy are fundamental and complementary investigations. Endoscopy, under general anesthesia, must be minute (with optics), explore oesophageal and laryngo-tracheo-bronchic tract, and use several tests to demonstrate permeability of the fistula when it has been located. A special technique is presented. Several points must be outlined: 1--classical symptoms of persistant fistula are not reliable in authors' experience; any recurrent respiratory and swallowing problem requires investigations; 2--endoscopy and radiographic study have to be repeated sometimes to prove fistula; 3--responsability of some anomalies must be always discussed, because of their possible association with a fistula; several fistulas may also exist.
