Let’s have a hand for the doctors over in Switzerland!

When conjoined twins were born, the doctors were going to wait several months before attempting to separate them with surgery. But after the twins contracted a fatal illness, the doctors moved the five-hour emergency surgery to just eight days after the twins were born.

Talk about pressure!

According to BBC, the operation had a 1% success rate. The twins were born with a rarely seen blood condition, where one twin was born with more blood in their system than the other.

The twins, Lydia and Maya, were born eight weeks premature at a hospital in Bern. A triplet was also born that day, and is fully healthy.

“It is the first successful operation of such small conjoined twins in Switzerland and possibly even worldwide, and therefore—apart from great luck for the parents—a medical sensation,” the hospital said in a statement on Jan. 31.

While the doctors were prepared for the worst possible outcome, they still went through with the surgery. This goes to show that they are dedicated in their medical oath to save lives. In this case, the babies were already out of the mother, so the surgeons only had to worry about the twins.

But with such a small window of success, even their small fates hung in the balance! One doctor in the surgery unit described the overwhelming feelings as “extreme” and said how they “were prepared for the death of both babies.”

The success of the surgery is a notable achievement not just for the surgical staff, but the entire medical team.

“The perfect teamwork of physicians and nursing personnel from various disciplines were the key to success here,” added Steffen Berger, head of the department of pediatric surgery. “We are very happy that the children and parents are faring so well now.”

Doctors expect Lydia and Maya to make a full recovery, but they are still being kept under observation in the hospital’s pediatric intensive care unit.

There are currently approximately 200 separated conjoined twins around the world. Sometimes referred to as Siamese twins, this phenomenon occurs in about one in every 200,000 live births.

Talk about amazing! Way to go, team! And congrats to Lydia, Maya, and their proud parents!
