People’s Hospital of Peking University successfully performed laparoscopic “waterjet” resection of hepatic hemangioma On November 7, 2006, a hepatic hemangioma of about 10cm in diameter was successfully removed from the patient’s body. On November 7, 2006, a hepatic hemangioma was successfully removed from the patient’s body by the Department of General Surgery (Hepatobiliary Surgery) of Peking University People’s Hospital, using the most advanced medical instrument in the world – “waterjet”. The patient was an ordinary worker, 54 years old, but she had been suffering from asthma for more than 20 years and her lung function was extremely poor. After being diagnosed with hepatic hemangioma, the doctor recommended her to undergo surgery, but it was extremely risky for this high-risk patient to undergo surgery under general anesthesia. Because of the high trauma of liver resection surgery, intraoperative bleeding and the number of complications that can easily occur, it is a great test for the patient’s cardiopulmonary function. After the patient was admitted to the Department of General Surgery of the People’s Hospital, a preoperative discussion was held under the organization and guidance of Director Leng Xisheng, and a thorough surgical plan was formulated based on the patient’s past medical history and current condition. In order to reduce the risk of surgery and postoperative trauma, the treatment team consisting of Prof. Wang Fushun, Dr. Chen Lei and Dr. Gao Jie decisively formulated a treatment plan of laparoscopic combined waterjet resection of hepatic hemangioma for the patient. The operation was very successful, with only 300ml of intraoperative bleeding, which was significantly less than that of a normal open operation. The patient woke up soon after the operation and was extubated in the operating room, which effectively prevented pulmonary complications, and the longest incision in the patient’s abdomen was only 3cm (for removing the specimen), which was significantly less traumatic than an open operation. ”Waterjet” is an instrument that has been used in clinical practice only in the past two years. It selectively cuts tissue through a spiral high-pressure water stream, just like a “laser”, with the advantages of precise tissue separation, less bleeding, clear surgical field, and effective reduction of operating time. At present, it is mainly used in open surgery. In addition, there are only a few hospitals in China that can remove part of the liver laparoscopically, and the combined use of waterjet under laparoscopy is a perfect combination of these two new technologies, bringing a boon to patients who need to remove part of the liver, especially high-risk patients.
