Study Notes
Open Repair of Tracheal Stenosis
- Open surgical repair is indicated after failed conservative management or endoscopic intervention.
- Various surgical procedures include patch tracheoplasty, segmental resection, wedge resection, tracheal autograft, slide tracheoplasty, and use of transplanted tissue (either autografts or allografts).
- Surgical approaches often involve intermittent distal tracheal intubation, extracorporeal membrane oxygenation (ECMO), or cardiopulmonary bypass (CPB) for stability and safety during complex repairs.
Preoperative Considerations
- Preoperative preparation includes antibiotic prophylaxis due to high pathogenic bacterial presence in affected patients.
- Management of comorbidities, such as gastroesophageal reflux disease (GERD), is crucial.
- Preoperative imaging is essential to identify associated cardiovascular anomalies and ensure strategic surgical management.
Simultaneous Repair and Outcomes
- Some institutions perform simultaneous airway and cardiovascular repairs typically using CPB.
- A study noted operative mortalities during simultaneous repairs, linking them to longer bypass times.
- Recommendations suggest staged reconstruction for patients with complex cardiac anomalies due to higher mortality rates.
Patch Tracheoplasty
- Patch tracheoplasty involves vertical midline division of stenosis with addition of anterior segment circumference.
- Initial reports used costal cartilage grafts in an infant with long-segment tracheal stenosis (CTS).
- Subsequent studies highlighted mixed long-term outcomes, with many patients experiencing residual stenosis and lengthy hospitalizations.
Materials and Techniques
- Autogenous pericardial patch is also used, with variable long-term success reported.
- A combination of pericardial patch and transverse costal cartilage struts showed favorable short-term outcomes (mean 5.5 days of postoperative intubation).
Advantages and Disadvantages
- Advantages of patch tracheoplasty include:
- Avoidance of tracheal mobilization and lateral dissection.
- Reduced risk to tracheal blood supply and recurrent laryngeal nerves.
- Less cicatricial scarring.
- Disadvantages include:
- Extended need for postoperative intubation or stenting to support the grafts.
- Risk of granulation tissue formation and restenosis due to mesenchymal tissue introduction into the airway.
Segmental Resection and Primary Reanastomosis
- Recommended for short-segment stenosis or severe malacia that cannot be treated otherwise.
- Key benefit is immediate restoration of a native mucosalized airway, which exhibits normal growth post-repair.
