Repeated diarrhea more than 4 years, has been a local hospital as "gastroenteritis" treatment, the final diagnosis of hepatic tumors have enormous. Yesterday, Mr. Wu Zhujiang Hospital, Southern Medical University successfully underwent surgery to remove the tumor. Surgery doctor in charge Professor Fang Chihua introduction, this surgery complicated, very difficult, if not by means of 3D printing liver model guidance, surgery can not be completed. It is reported that the use of 3D printing instructions to complete the complicated liver tumor resection, first in the country. Tumor "shape small watermelon," Mr. Wu liver tumor volume is large, are more than 10 cm length and breadth, Zhujiang Hospital of Southern Medical University medical staff describe "the shape of a small watermelon." However, the biggest difficulty is not bulky tumor surgery, the patient's pulmonary artery and portal vein there are three variations of the team must be precisely determined breakthrough surgical resection plane, at the same time to remove the tumor, cut off to ensure that no important vessel. If you are using a conventional method of lung resection, clear the Wu tumor at least to cut 59.24 percent of the lungs. "It is not feasible, because patients with cirrhosis of the liver, liver cirrhosis liver surgery must retain a minimum of 50%, less than 50% bound to postoperative liver failure, life-threatening or even lead to death." Professor Fang Chihua said. Model allows physicians visual recognition

Encountered this difficult surgery, Professor Fang Chihua Hepatobiliary Division, he led digital medical team uses 3D printing technology, the successful print out the three-dimensional simulation of liver cancer in patients with liver model. Team of the model into the operating room, the surgeon for real-time identification and location of key parts, guide important separation and tumor vascular lesions removed. After more than five hours of surgery, the success of the giant tumor resection operation completed successfully. Professor Fang Chihua said that with the help of 3D printing technologies, they develop and implement the best removal programs, avoiding major blood vessels, only 42.75% liver resection. According to the surgeon introduced to preserve as much normal liver tissue on postoperative recovery has a very important role, but also because "under the knife" precise clever, very little blood loss in patients. 3D printing organ widely Professor Fang Chihua say, the medical profession to be seen as a technological revolution in 3D printing, it realized from the "three-dimensional images of the human brain", "three-dimensional computer images" to "true three-dimensional anatomical kind of" change. Professor Fang Chihua description, good 3D printing technology medical applications. Now 3D model not only in human organs now used for preoperative planning and surgical navigation indirect, and have organs 3D printing are as follows jaw, organ support, skull, spine, pelvis, etc., have already entered the clinic. Future, will achieve living tissue and organs 3D printing helps in-depth study of human diseases. In addition, 3D printing model can also be applied to preoperative discussions and training of young doctors, patients and their families at the same time to facilitate intuitive understanding of the disease can be detailed, correct understanding of the risk of surgery, thereby forming a good doctor-patient communication, reduce possible disputes. However, 3D printing guide surgery clinical aspects, there are still difficulties, first of expensive, and because the printing material reasons, finished fragile and easily damaged. It is understood that this 3D model ready for each surgery cost more than 3,000 yuan, it took over 20 hours to print out.
