"There are a total of eighteen special lectures and two academic reports today, which is a little less than tomorrow. It will end at six o'clock in the afternoon, and the lunch break will be about two hours."
"If there is a surgical demonstration in the special lecture, it will probably take a long time, and you may not be able to finish it even after lunch."
"Don't you have confidence in the surgeons here in the capital?"
"The operation time of hepatobiliary surgery is relatively long. If they start the operation in the hospital early, we will not be able to see it in time."
"If there is a demonstration of surgery, do you want to watch it?"
"Look. But it depends on who performed the surgery and what kind of surgery."
Listening to the discussions of these people, it is similar to the estimated situation discussed in their department. Xie Wanying thought.
"I know Professor Hao from Juyang Hospital." A colleague suddenly pointed out one of the lectures and said.
"This is a lecture that starts at 8:30, and the topic is PTCD intrabiliary radiotherapy."
The placement of bile duct stents after percutaneous transhepatic biliary drainage is mainly used in cancer patients with pancreatic head cancer, cholangiocarcinoma, ampullary cancer, etc., which are difficult to detect in the early stage and will be in the middle and late stages once discovered. These patients also have a characteristic, high
He had poor cardiopulmonary function and could not tolerate radical surgery, so he could only undergo palliative treatment.
This treatment method only relieves malignant biliary obstruction caused by late-stage cancer. However, the stent itself cannot inhibit tumor growth and will continue to grow along the drainage stent to cause obstruction again. In order to keep the drainage smooth, doctors have thought of many ways to avoid stent obstruction.
, one of which is the transcatheter 192lr wire used for brachytherapy in the bile duct, which was pioneered abroad in the 1980s.
192lr is the radioactive source iridium-192, and Ir is the nuclide symbol. It is a relatively mature technology used for various brachytherapy in the human body. The first cancer that is widely used in the human body is cervical cancer, and then extends to bile duct cancer and tongue.
Cancer, etc. In the application of cervical cancer, it can be used as one of the treatments to shrink tumors before surgery. In hepatobiliary surgery, it is only used as late-stage palliative treatment.
Palliative care is equivalent to treatment measures that basically have no long-term hope for patient survival. Statistics from various academic papers show that the survival time of patients with malignant biliary obstruction is generally only two months. PTCD plus 192Lr brachytherapy is used
If so, the patient's survival period can be extended to more than two years at most, depending on the size of the tumor. For patients with advanced cancer to live just one more day, it is meaningful.
The doctors discussed above decided to listen to Professor Hao's lecture on PTCD intrabiliary radiotherapy first. Xie Wanying followed her, mainly because she saw that there were many people attending the lecture. It can be seen that everyone's tendency is basically the same.
The multimedia conference rooms reserved in the hotel are basically converted from small halls and small rooms. They are not large in area. After entering, some of them only have about a hundred seats. Entering the conference room, I found that the seats in the front row were full of people. Xie Wanying found a seat
Sit in the back seat.
Just as she was next to the chair, two people came in from the door. One of them noticed her figure and turned around and walked towards her.
"Isn't that Xie Wanying?"
When she heard someone calling her name, Xie Wanying raised her head. The tall male doctor standing in front of her had a briefcase on his shoulder, and his face seemed familiar to her.
"Don't remember me? I remember you very much. You and the other two went to the emergency department of our Xuanwu Hospital that night. What happened to you after Dr. Cao took you back?"
