TEF Presentations (Extended): Aerodigestive & Esophageal Surgery
The bugbee cautery is useful and underutilized among general surgeons for treating recurrent tracheoesophageal fistulas.
opinionTodd Ponsky0:04 ↗
A 70-degree endoscope is a difficult tool to use but useful for tracking down hard-to-find tracheoesophageal fistulas.

Routine bronchoscopy is now standard practice for all type C esophageal atresia cases, though this represents a change from earlier training when it was not necessarily performed.

General surgeons may underappreciate tracheomalacia or laryngomalacia, making collaboration with ENT colleagues valuable for comprehensive airway assessment.
opinionTodd Ponsky1:53 ↗
Pediatric surgery fellows at this institution complete a one-month attachment with ENT to perform bronchoscopies as part of their training.

Dual scoping (simultaneous bronchoscopy and esophagoscopy) is enormously valuable for complicated TEF patients, providing different information and advantages in visualization.
clinicalDan6:41 ↗
During dual scoping, you can see the light from one scope through the epithelium, inject material that may come through subtle holes, or observe bubbles from air insufflation, making simultaneous visualization quite valuable.

For combined bronchoscopy and esophagoscopy in small children, a 2.8 mm flexible bronchoscope is typically used alongside an infant gastroscope (5.4 or 6 mm outer diameter).

An infant gastroscope will fit retrograde through a 16 French gastrostomy tube.

The concept of endoscopic TEF repair is to demucosalize the tract because mucosa is a non-stick surface; you want raw against raw with a tiny bit of fibrin glue to seal it while it scars off.
clinical11:01 ↗
When using fibrin glue for TEF repair, use a very small amount (about 0.1 ml) via a Duplo double-lumen catheter to avoid forming a foreign body.
clinical11:36 ↗
Trichloroacetic acid (TCA) can be used for TEF demucosalization, but it is difficult to control precisely and leaves white tissue everywhere, whereas the bugbee provides more precise control.
clinicalTodd Ponsky12:21 ↗
When using bugbee cautery for TEF repair, place something in the esophagus (such as an endotracheal tube) as a spacer to avoid burning the back of the esophageal wall.
clinical13:36 ↗
A bugbee catheter will go down an EGD scope, allowing cauterization from the esophageal side if the tract angle is favorable.
clinical14:29 ↗
A 3 French bugbee fits through a 2.8 mm flexible bronchoscope with a 1.2 mm suction channel, providing precise control of the tip.

When passing a bugbee through a rigid scope, bending the end at a slight angle before insertion allows steering by rotation.
clinical15:32 ↗
Endoscopic TEF repair often needs to be performed more than once; the average is approximately 2 procedures, with some requiring 1 and others 3-4 attempts.
clinical22:37 ↗
The success rate for endoscopic TEF closure is running about 80%, not 100%.
clinical24:18 ↗
After 3 or 4 failed endoscopic TEF repair attempts, it is typically time to give up and discuss alternative approaches.
clinical24:27 ↗
When cauterizing a TEF, you should particularly try to get the edges and sides because as they scar in, that will narrow the whole mouth, making re-intervention easier if needed.
clinical24:59 ↗
To reduce airway fire risk during bugbee cautery, insufflated oxygen should be kept at 30% or less.
clinical25:51 ↗
Patients can tolerate a minute or two of lower oxygen saturation during cautery procedures to maintain safe oxygen levels below 30%.
clinicalBob Wood26:10 ↗
Radiance voice gel (used for vocal cord injection) can be injected into the wall beside a TEF to obliterate the potential space and hold raw surfaces together; it only lasts a few weeks.
clinical27:05 ↗
For TEF repair, all that matters is achieving raw-on-raw tissue contact for healing.
clinicalTodd Ponsky1:09:25 ↗
Thoracoscopic diaphragmatic hernia repairs may have a higher recurrence rate than open repairs, possibly because they do not cause enough raw-on-raw tissue contact.
opinionTodd Ponsky1:09:33 ↗
Slide tracheoplasty is a useful technique for big complex TEF holes, using part of the trachea to repair the esophageal defect.
clinical30:55 ↗
Sternal periosteum is an excellent interposition graft material—it is like Kevlar, bulletproof, abundant, and very strong, though almost impossible to suture.
clinical34:02 ↗
Slide tracheoplasty appears to be a learning-curve, surgeon-dependent operation, unlike many operations where the surgeon does not matter long-term.

Button batteries are extremely dangerous and can cause ongoing tissue damage that extends beyond what is visible and beyond the expected time frame.
clinicalDan43:17 ↗
The institutional protocol for button battery ingestion is to remove them within 2 hours of identification, as it is considered a medical emergency.
