This is the joyous moment two conjoined twins were successfully separated after undergoing surgery in a hospital in eastern China.

The medical triumph was carried out at the Zhejiang University Children’s Hospital in Hangzhou city, in Zhejiang Province.

The sisters who were born with connected abdomens and shared an umbilical cord were surgically separated after two and a half hours op 40 days after their birth.

Following the separation, the pair underwent simultaneous sternum, diaphragm and abdominal wall repair operations in two adjacent operating rooms.

The chief surgeon of the operation and hospital director said that at present, the vital signs of both sisters are stable.

In the footage, the twins can be seen going into the operating room at around 9:00am, and coming out at 11:20am as separate babies.

A team of medical professionals accompanied them out of the operating room whilst filming the happy moment each of the sisters was given their own tag, officially marking them as two separate individuals.

They retained their complete organs and their abdomens are reportedly almost the same as that of an ordinary person.

Although they are both currently held in the intensive care unit, the medical team is optimistic about their recovery.

Even though one of them suffers from complex congenital heart disease, she is expected to have a positive health outcome.

For the first time in their lives, the sisters were able to both lie flat and doctors were able to weigh them individually.

One sister weighed 6.7 pounds (3 kilogrammes), and the other one tipped the scales at 5.07 pounds (2.2 kilogrammes).
