Tracheoesophageal Fistula Repair (Pediatric) - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: A tracheoesophageal fistula is a birth defect in which the esophagus has an abnormal connection to the trachea. The esophagus is the tube that food passes through from the mouth to the stomach. And the trachea is the wind pipe that air passes through from the mouth and nose to the lungs. The trachea forms during the sixth week of pregnancy. Here you can see the tube that will eventually form all the organs of the digestive system. The trachea and lungs grow from a part of the digestive tube that will eventually become the esophagus. For unknown reasons, the esophagus and trachea may grow and separate abnormally during this time. The esophagus may end in a blind pouch with missing gaps, and be abnormally narrow. This absence, or narrowing, of a natural body passageway is called atresia. The esophagus and trachea may also have an abnormal connection called a tracheoesophageal fistula. Here we see the most common type of tracheoesophageal fistula in a newborn infant. The upper esophagus ends in a blind pouch. And the lower esophagus connects to the trachea. This is a serious problem, because stomach contents can travel up the esophagus and pass through the fistula into the trachea and lungs. The fistula can also cause difficulty breathing for the newborn, since air can now bypass the lungs and enter the stomach. Before a tracheoesophageal fistula repair procedure, an intravenous line will be started. The baby maybe given antibiotics through the IV to decrease the chance of infection. The baby will be given general anesthesia, which will put the baby to sleep for the entire operation. A breathing tube will be inserted through the mouth and down the throat to help the baby breathe during the operation. The surgeon will make an incision in the baby's chest, usually on the right side. Through the incision, the surgeon will gently move the lungs aside to view the trachea and esophagus. After identifying the tracheoesophageal fistula, the surgeon will slowly close the fistula's connection to the trachea with sutures, then cut the connection away from the trachea. The fistula's connection to the esophagus will also be cut, and the fistula will be removed. Next, the surgeon will make an incision at the end of the upper esophagus to open it. Then, the upper and lower esophagus will be connected with sutures. Finally, the surgeon will insert a surgical drain in the chest and close the incision with sutures. After the procedure, the baby will continue to use the breathing tube until they've healed enough to breathe on their own. The baby will be taken to the neonatal intensive care unit for monitoring. Pain medication will be given. The baby may continue to receive antibiotics through the IV. Babies are released from the hospital when they're able to eat enough to maintain their weight, which may be after two weeks or longer.
"The Doe Report is a visual feast of medical information for personal injury
lawyers."
Aaron R. Larson, Esq. President ExpertLaw.com
"Whether it's demonstrating a rotator cuff tear, neck movement a few
milliseconds after rear impact, or a proposed lumbar fusion, the Doe Report
represents an instant on-line database of medical illustration for
health-care and legal professionals.
Illustrations can be purchased 'as is' or modified within hours and sent
either electronically or mounted on posterboard. An illustration is worth a
thousand words, as juries perk up and look intently to capture concepts
that are otherwise too abstract. Start with good illustrations, a clear and
direct voice, a view of the jury as 12 medical students on day one of
training, and your expert testimony becomes a pleasure, even on cross
examination. An experienced trial lawyer should also emphasize these
illustrations at the end of trial, as a means of visually reinforcing key
concepts covered.
As a treating physician, I also use these accurate illustrations to educate
my own patients about their medical conditions. The Doe Report is an
invaluable resource, and its authors at MLA have always been a pleasure to
work with."

"Medical illustrations are essential during trial for any medical malpractice case. The people at MLA have the uncanny ability of creating medical illustrations that simplify the most complex of medical concepts and human anatomy to a lay audience. The exhibits of MLA allow experts to easily describe complex concepts and human anatomy in a manner that could
not be done otherwise.
In addition, their custom illustrations show in great detail the extent of
injuries suffered and the devastating effects they have had on the client's
anatomy. These custom illustration can show, side by side, the body before
and after a catastrophic injury. The effect of this juxtaposition is
unmatched by any testimony that can be adduced at the time of trial.
Even jurors after trial have commented on the ease with which they grasp
medical concepts and anatomy once the MLA exhibits were introduced and
used by my experts. Even judges who have "seen it all" are thoroughly
impressed by the detail and sophistication of the illustrations.
"Medical Legal Art has always performed quality and efficient work. The
doctors that review the exhibits are always amazed at the precise
descriptions and drawings."
