Youngest conjoined twins were separated successfully by Swiss doctors at Bern University Hospital.The eight-day old sisters with attached chest and liver went through a 5-hour long operation.

A team of six anaesthesiologists, five surgeons, and two nurses carried out the operation on December 10, which only had one percent chance of success.  Its is possibly the most successful operation in Switzerland and in the world.

On December 2, a mother gave birth to triplets, with two conjoined babies and one separate. The twins, Lydia and Maya weighed just 4lb 14oz and had all other essential organs. Third baby, Kamilla was born normal.  The mother’s condition was not well during birth so doctors had to carry out Caesarean section.

Doctors had to operate even if the plan is to do it after a few months when the babies are older.  But after the twins suffered from a life-threatening condition, they decided to  do the operation when one twin was reported having too much blood and other with little blood flow.

According to the doctors, the twins are better than before the operation.  They have both actually put on a little weight. They have started the breastfeeding, according to report by Evening Standard.

Head of pediatric surgery Steffen Berger was quoted saying in a report by Evening Standard: “The perfect teamwork of physicians and nursing personnel from various disciplines were the key to success here.  We are very happy that the children and parents are faring so well now.”

Barbara Wildhaber, head of the pediatric surgery unit at the Geneva University Hospital, said that the pressure was extreme on both the lives as their lever were adjoined with each other. She headed the team for operation.

“We were prepared for the death of both babies, it was so extreme. It was magnificent! I will remember it my entire career” said Wildhaber.

According to University of Maryland Medical Centre, such cases of conjoint twins are one in 200,000 live births; they are also known as Siamese twins.

So far there are 200 cases of conjoined twins living worldwide. Generally,the possibility of survival in such cases is 5 to 25 percent, according to a report by NDTV.
