JEDDAH: In accordance with the directives of King Salman and Crown Prince Mohammed bin Salman, it has been decided to conduct the separation of the Saudi Siamese twins Sheikha and Shumukh at King Abdullah Specialist Children’s Hospital in King Abdul Aziz Medical City on Thursday. Dr. Abdullah Al-Rabiah, the head of the medical and surgical team, explained that the twin females, four months old, weigh 5.2 kilograms each and are attached at the lower abdomen and pelvic region.  He added that both have full lower limbs and are linked in the pelvic area, the lower digestive system and the reproductive system. Al-Rabiah predicted that the operation will take 12 hours in seven stages, involving about 25 doctors and specialists as well as technicians and nursing staff. He pointed out that this humanitarian program has served 21 countries in three continents, and the Kingdom will, he hopes, register success with this latest surgery.
