A 30-People Medical Team From Texas Children’s Hospital Separates Ten-Month-Old Conjoined Twins In A Grueling 26-Hour First-Ever Surgery.

Conjoined ten-month-old twin girls, who were connected at the chest and abdomen, were separated in Texas after a grueling operation that had never been successfully performed before.

Knatalye Hope and Adeline Faith Mata were born last April in Lubbock, Texas, to parents Elysse and John Eric.

The couple knew that their baby girls would be conjoined and when they were born, doctors found that they shared the same chest wall, lungs, pericardial sac (the lining of the heart), diaphragm, liver, intestines, colon and pelvis. (Scroll down for the video.)

Earlier this month, a 26-member medical team, including 12 surgeons, six anesthesiologists and eight surgical nurses, operated to separate the 10-month-old girls at the Texas Children’s Hospital.

The marathon 26-hour operation marked the first time twins conjoined at the chest and abdomen in this way had been successfully separated.

Their mother Elysse said she can’t thank the surgeons enough for giving her babies the chance to live separate lives. She said:

We know how much planning and time went into this surgery and we are so blessed to be at a place like Texas Children’s where we have access to the surgeons and caretakers that have made this dream a reality.

We also want to express our gratitude to all of the people that have prayed and provided support to our family over the last 10 months.

4. The girls’ father John Eric struggles contain his emotion after both of his daughters survived the operation, which had never before been attempted.

To prepare them for the surgery, Knatalye and Adeline underwent a five-hour procedure in December to insert custom-made tissue expanders into their chest and abdomen. These helped to stretch the babies’ skin to prepare them for the separation surgery.

Models of the babies’ organs were also created so doctors could perform simulations of the surgery, prior to the actual operation.

During the surgery, the team worked for around 23 hours on Knatalye and for 26 on Adeline, with the official separation occurring 18 hours into the procedure.

7. Mr. and Mrs. Mata personally thank some of the medical team that operated on their daughters. In total 12 surgeons, six anesthesiologists and eight surgical nurses carried out the surgery.

Dr. Darrell Cass, a pediatric surgeon said:

This is the first time a separation surgery for thoraco-omphalo-ischiopagus twins with this particular configuration has been successful.

This surgery was not without its challenges with the girls sharing several organ systems.

Our team has been preparing for this surgery for months and we’ve done everything from working with our radiology experts to build a 3-D model of their organs, to conducting simulations of the actual separation surgery.

The babies are now being cared for in the hospital’s pediatric intensive care unit, where they will remain for the next couple of months.

No date has been for their release from Texas Children’s Hospital, as it is believed that they will have to undergo additional procedures in the future.

10. Doctors prepare to begin the procedure after the girls are given anesthetic. The surgery was the first time it had been carried out successfully.
