On August 16, 2000 (July 17, 2000 in the lunar calendar), a rare conjoined baby was successfully separated in Chongqing. On August 16, 2000, a pair of rare thoraco-abdominal conjoined babies were recently successfully separated at Xinqiao Hospital of the Third Military Medical University (the separation operation is the third case in the world and the first in China). At present, all vital indicators of the two babies are normal. After search, this separation operation is the third case in the world and the first case in China. On May 12, 2000, Wen Xueqing, a farmer in Nanchong City, Sichuan Province, gave birth to a pair of male babies with their chest and abdomen. Because the chest and abdomen are connected and multiple organs are connected, separation of this conjoined baby is very difficult. The internationally accepted surgical method is to sacrifice one and preserve the other. With her trust in the PLA doctors, Wen Xueqing came to Xinqiao Hospital with her children at the end of June. Zhao Xianzhu, president of the hospital, and Su Baocheng, political commissar of the hospital, attached great importance to it and immediately mobilized experts from 17 departments to form a diagnosis and treatment team to use advanced testing methods to conduct diagnosis. The male boy's chest and abdomen connection circumference reaches 38 centimeters, their hearts are connected, and their liver is shared. They weigh only 7.5 kilograms. They are weak and have a high risk of separation. In order to ensure the success of separation, the doctors first performed preoperative treatment and careful feeding on the conjoined baby in pediatrics. After its weight increased to 9.5 kg, the doctors worked out 6 sets of plans through 8 discussions, which were held on August 16. The separation operation started at 8 a.m. After opening the chest and abdominal cavity, the situation was more complicated than expected. Both connected hearts had congenital heart disease and were severely ectopic. The shared liver thickness reached 8 centimeters, and the gastrointestinal tract and biliary system were intertwined. The experts first separated and repaired the heart with skillful techniques, followed by the original "local blocking and blood-free liver separation method" to safely separate the liver. Finally, using novel pediatric plastic surgery, they sutured the two infants with defects reaching 18 cm in diameter and 12 cm in transverse diameter. The thoracic and abdominal cavity. The operation lasted for a full 8 hours and was successful.
