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.
