QUAD #1: Cervical Tracheopexy with Dr. Alessandro de Alarcon

Foundation: The Combined Approach Framework

Cincinnati Children's typically uses a combined cervical and thoracic approach for esophageal atresia cases 0:49. This is not simply a matter of preference — the combined approach is valuable for complicated cases or patients needing additional operations for symptom relief 3:24. The preoperative workup reflects this complexity: dynamic CT imaging, pulmonary function tests, microlaryngoscopy and bronchoscopy, and flexible bronchoscopy 0:55. Each modality answers a different question about the airway and the degree of compression.

Airway Control: Positioning for Visualization

Endotracheal tubes are often placed nasotracheally with the cuff positioned high, sometimes almost at the glottis 1:29. This is not carelessness — flexible bronchoscopy during the operation is key for visualization 1:21, and the tube must be positioned to allow the pulmonologist to see through it while the surgeons work. A NIM tube is used when possible to prevent potential injury to recurrent nerves or provide awareness when getting close to them 1:39. The setup determines what you can see, and what you can see determines what you can safely do.

Exposure: Mobilizing What Others Fear

The surgical approach uses standard neck incision with subplatysmal flaps raised 1:55. Residual or regrown large thymus can be removed during the cervical approach as it is in the way 2:01. Aortopexy and innominate artery pexy can be added at the same time as the cervical approach 2:09. In the lateral approach, surgeons work on the side of the airway to find the esophagus 2:19, and pediatric surgeons find the recurrent nerve for the ENT team to help prevent injury 2:23.

The esophagus is mobilized above the level where the team aims to pexy 2:43. Mobilizing the esophagus above the pexy level makes it easier to place sutures exactly where needed 2:49. This is the judgment call that separates experience from hesitation: being willing to move the esophagus to get the exposure you need. Stitches are sometimes placed in the trachea to pull it up and out of the way to visualize the posterior aspect where the spine is visible 2:54.

Suture Placement: Sequence and Spontaneous Ventilation

A pulmonologist assists with visualization inside the trachea using flexible endoscopy through the endotracheal tube while stitches are being placed 3:02. 3-0 Prolene sutures are used for the tracheopexy 3:15. All stitches are placed before securing them down, and this is done under spontaneous ventilation conditions 3:15. Placing all sutures before tying allows you to assess the functional result — whether the airway opens adequately with spontaneous breathing — before committing to the construct. Positive pressure ventilation will open any airway; spontaneous ventilation tells you whether the pexy works.

Outcome Assessment: The Imaging-Symptom Discordance

Outcome measures include endoscopy follow-up, potentially PFTs when patients are old enough to perform them, and imaging 4:00. At 36 months follow-up, imaging may still show some tracheomalacia even when patients are symptomatically better 4:09. This is the point that changes management: imaging findings do not define success. The field is still trying to learn exactly what measures should be used to define good versus bad outcomes 4:15. A patient who breathes well, feeds well, and grows is a success even if the CT shows residual collapse. Potential complications include swallowing dysfunction and vocal fold paralysis 4:26, which is why otolaryngology involvement is important both in the procedure and during follow-up, and is easier when already built into the team 4:32.

The teaching progression here moves from setup to exposure to suture technique to outcome interpretation. The most subtle point — and the one most likely to change practice — is the last: that imaging at three years may still show tracheomalacia in a patient who is clinically well, and that this discordance is expected rather than a failure of the operation.

Airway Access and Nerve Monitoring

Endotracheal tube positioning for cervical tracheopexy demands precision that conflicts with standard anesthetic practice. The tube is often placed nasotracheally with the cuff positioned high in the trachea 1:29. This placement enables continuous flexible bronchoscopic visualization through the tube during suture placement 3:02, but requires explicit communication with anesthesia about the non-standard cuff position. When feasible, a NIM tube is used "to prevent potential injury to recurrent nerves or at least make you aware when you're getting close to them" 1:39. The recurrent nerve becomes the pediatric surgeon's responsibility early in the dissection — they identify it for the ENT team before esophageal mobilization begins 2:23.

Esophageal Mobilization Above the Pexy Level

The Cincinnati approach centers on aggressive esophageal mobilization, a maneuver many surgeons avoid in this anatomic corridor. "We have learned how to not be afraid of the esophagus," de Alarcon states 1:39. The esophagus is mobilized above the level where the pexy will be performed 2:43, creating working room that makes precise suture placement possible 2:49. This is not mobilization for the sake of exposure — it is mobilization to control exactly where the pexy stitches engage tissue. Without this step, sutures go where anatomy allows rather than where physiology demands.

Visualization Strategy for the Posterior Tracheal Wall

Placing anterior tracheoesophageal pexy sutures requires seeing the posterior tracheal wall and the prevertebral fascia beyond it. The team uses traction stitches placed directly in the trachea to lift it anteriorly and laterally, exposing the posterior aspect "where you see the spine" 2:54. Simultaneously, the pulmonologist maintains flexible bronchoscopy through the endotracheal tube, providing real-time intraluminal visualization as each suture passes through the tracheal wall 3:02. This dual-view approach — external surgical field and internal airway lumen — prevents full-thickness bites and confirms that sutures do not compromise the airway.

Suture Technique and Spontaneous Ventilation

All sutures are placed before any are tied 3:15. The material is 3-0 Prolene 3:15, and placement occurs under spontaneous ventilation conditions 3:15. Spontaneous breathing allows the surgical team to assess the functional result before committing to it — if the pexy over-restricts tracheal motion during spontaneous respiratory effort, the problem is evident before the knots are tied. Positive pressure ventilation masks this; spontaneous ventilation reveals it.

Outcome Assessment: Imaging Lags Behind Symptoms

At 36 months post-operatively, imaging may still demonstrate tracheomalacia even when patients are symptomatically improved 4:09. This dissociation between radiographic appearance and clinical function is not a failure of the operation — it is a feature of airway remodeling that the field has not yet learned to interpret. "We're still trying to learn exactly what are those measures that we want to use to be able to say that they are a good outcome versus a bad outcome" 4:15. Outcome measures include follow-up endoscopy, pulmonary function testing when age permits, and imaging 4:00, but the weight given to each remains unsettled. The error is treating persistent imaging findings as equivalent to persistent disease when the patient has returned to normal activity.

Multidisciplinary Structure as Risk Mitigation

The combined cervical and thoracic approach is used for complicated cases or patients requiring additional operations for symptom relief 3:24. Potential complications include swallowing dysfunction and vocal fold paralysis 4:26, and otolaryngology involvement in both the procedure and follow-up is critical and more readily implemented when the team structure is already established 4:32. The value of the multidisciplinary structure is not collaboration in the abstract — it is having the subspecialist who can diagnose and manage vocal fold paralysis already embedded in the care pathway when it occurs, rather than discovering the complication weeks later when the patient presents elsewhere.
