For thoracoscopic EA/TEF repair, the gap between proximal and distal esophagus should be assessed preoperatively using X-ray with nasogastric tube and bronchoscope positioning to identify the fistula orifice.
ClinicalYama
Leaving one-quarter of the fistula uncut prevents cranial retraction of the distal esophagus and makes anastomosis easier.
ClinicalYama
Preserving one-fifth to one-quarter of the proximal esophageal tip provides a 'cap' for grasping without touching the anastomotic site.
ClinicalYama
If there is a 1-2 to 3 vertebral body gap, the assistant can pull the proximal esophagus caudally using the uncut cap.
ClinicalYama
The first stitch should be placed in the middle of the posterior wall rather than at the edge.
ClinicalTodd Ponsky
Optical trocars are used for initial port insertion in this technique.
ClinicalYama
The mucosa of the distal esophagus must be included in sutures to prevent postoperative stenosis.
ClinicalYama
6-0 PDS suture is used for the anastomosis.
ClinicalYama
The tracheoesophageal fistula is divided completely after 1-2 stitches are placed.
ClinicalYama
The uncut cap of the proximal esophagus is divided after 2-3 stitches are placed.
ClinicalYama
Todd Ponsky tried Yama's technique after seeing the video in September and found it worked well, though he was uncertain how much the traction contributed versus standard technique.
OpinionTodd Ponsky
There is no downside to leaving the last bit of fistula attached—if the stitch sets up perfectly, it can be taken; if not, it can be cut.
OpinionTodd Ponsky
David Vanderzee uses a transfixing suture to close the fistula rather than clips to ensure it doesn't come off.
ClinicalDavid Vanderzee
David Vanderzee avoids clips because they tend to hook behind the suture being used for anastomosis.
ClinicalDavid Vanderzee
For type C anastomosis with considerable length, David Vanderzee places two sutures and makes them into sliding knots to slowly bring the ends together, dividing tension between the two ends.
ClinicalDavid Vanderzee
David Vanderzee finalizes the posterior anastomosis before placing a tube and closing the anterior wall.
ClinicalDavid Vanderzee
Jeff Blair predicts that in the next decade, mechanical devices will be developed that can be passed through the upper pouch to mechanically grab and seal the lower pouch, possibly with thoracoscopic or imaging guidance.
OpinionJeff Blair
Suet found the fistula much easier to identify and appreciate laparoscopically, allowing better assessment of how much esophagus to leave on the tracheal side.
ClinicalSuet
Suet found dissecting the upper esophageal segment difficult, particularly in handling the esophagus without damaging the wall needed for anastomosis.
ClinicalSuet
Todd Ponsky's experience with thoracoscopic TEF repair (3 cases over one year) has been that the first half during dissection and fistula division feels advantageous, but the anastomosis phase makes him question the approach.
OpinionTodd Ponsky
Todd Ponsky has experienced a clip eroding into the esophagus.
ClinicalTodd Ponsky
Todd Ponsky uses metal clips, the same type Steve Rothenberg uses.
ClinicalTodd Ponsky
Weck Hema lock clips are used by many surgeons, but the applier is large and impairs visualization compared to metal clip appliers.
ClinicalTodd Ponsky
Weck Hema lock clips are difficult to remove if their position is unsatisfactory.
ClinicalTodd Ponsky
If the fistula clip is applied very tightly, it will crush the esophageal muscle and cause erosion, leading to recurrent fistula; the clip should just oppose the tissue rather than crush it.
ClinicalYama
Mark Woflan from Atlanta uses a technique where a stitch is placed through the chest wall, through the proximal end, through the distal end, and back out through the chest wall, holding the ends together during anastomosis.
Host summaryTodd Ponsky · not cited in answers
Several instances have occurred where clips seem to erode or be implicated in recurrent fistula.
Host summaryTodd Ponsky · not cited in answers
Steve Rothenberg uses clips routinely and has the largest experience, but has never had a clip erode.
