Zhang invented CAES treatment for his father There is such a father and son in Nanjing. The father, who has been suffering from a persistent disease for decades, and the son, who has become a gastroenterologist. The son is grateful to his father and researches new treatment devices and techniques to solve his father’s pain; the father trusts his son and is willing to be the child’s first patients to verify this innovative treatment method. This is Zhang Invention, deputy director of the Gastroenterology Center of the Second Affiliated Hospital of Southern Medical University and director of the Key Laboratory of Integrative Gastroenterology of Southern Medical University, and his old father. In order to help his old father, who has been plagued by the disease for decades, Zhang Inveng developed a new device and method to treat his father’s persistent disease. The new technique was recently published in an international English-language journal. A “minor ailment” that has plagued his father for decades. “As a doctor, I’ve treated many people, but it’s hard to watch my own father suffer for years because of his illness. So I thought, “I have to cure my father’s disease no matter what.” Zhang Invention told reporters. According to Zhang’s own recollection, when he was in middle school, there was a time when the school wanted to build a basketball court and needed to carry stones from the river bank, a task that was divided among each student. His father used a hand-pulled cart to transport the stones, because the load is too high, the road slope and large, the result just after the last car, the father lying on the corner of the wall vomited, and then breathless to go to the toilet. When he came out, his father said he sprayed blood from his anus, and also took out a section of intestines, or slowly by himself back to the top. At that time, Zhang Inveng, who was just a student, did not know that his father was suffering from a persistent disease. After that, he heard from time to time that his father had an attack of the old disease, people around him said it was hemorrhoids, but it was “a big deal”, plus the medical environment was limited at the time, so his father kept putting it off. Later, my father became less inclined to go out, and he always temporarily “stood up” when we said we would go out as a family. “I didn’t know much at that time, but now I think back, it was because his rectum would ‘fall out’ from time to time, and hemorrhoids were bleeding more and more, so he didn’t want to go out.” Zhang Invention lamented. Later, Zhang’s father was diagnosed with internal hemorrhoids combined with rectal prolapse, and the situation was quite serious. After becoming a doctor himself, Zhang Invention asked the old man to undergo surgery, but the old man refused to do so. He just listened to the experience from a “master” he knew, using a strip of cloth from the shoulder down, across the root of the thigh, and then “pocket” the anus from below to avoid the rectum “fall”. out. Although this method is still somewhat effective, the old man relied on this “bandage” and lasted a broken time, but still inconvenient and very uncomfortable. As a doctor, Zhang felt that this would not work. Although there is a folk saying that “the doctor does not heal himself,” but as a doctor, he has treated so many patients, but can not help his own father? But the old man just refused to accept the surgery, the existing method can not be used, and can not find a better treatment method, so what to do? Zhang felt that he had to do something. During his 2 studies at Johns Hopkins Hospital in the United States, he was looking for and thinking of new techniques to treat his father’s disease. A “new design” that would make the “old technology” newer and safer. The method that Zhang came up with is called “transparent cap-assisted endoscopic sclerosis,” or CAES for short. The name sounds really foggy to the average person, but Zhang explained it simply: “To put it plainly, we are changing the traditional technique of hemorrhoid sclerosis treatment from the traditional naked eye The problem is solved by changing the traditional naked eye observation to endoscopic assisted completion, along with a special ‘transparent cap’ and a special injection needle.” According to the report, the sclerotherapy injection treatment of hemorrhoids is not new in itself, but a technology that has matured. This method allows hemorrhoids to harden, atrophy and gradually scarify by injecting a sclerosing agent into the hemorrhoid so that it no longer bleeds and also solves some of the other problems brought on by the hemorrhoid. At the same time, it does not require bleeding as occurs with surgical incisions and does not require the patient to rest in bed for a long time after the procedure. This is why the technique has been so popular in Europe and the United States as a convenient and effective “office procedure” and has been highlighted in the New England Journal of Medicine as one of the most effective treatments for bleeding hemorrhoids. However, traditional sclerotherapy is performed under the naked eye of the surgeon with the assistance of a speculum. In this case, the operation may injure the urethra or other parts of the body if the injection position deteriorates, leading to complications, also known as medically induced injuries. With the widespread development of hemorrhoid surgery in China, this “office surgery” has become less and less common. Zhang led his team to develop a special injection needle for hemorrhoids that can be controlled under the colonoscope based on the principle of traditional sclerotherapy, adding a “transparent cap” in front of the colonoscope, which is a transparent “small cap” worn specifically in the front section of the endoscope. “You can not look at this ‘small cap’, it is transparent, and does not prevent the endoscopist’s observation; at the same time it can better support the intestine, to avoid the intestine because of its own peristaltic relationship, affecting the doctor’s vision, not injected to bring unknown risks, so that the treatment becomes safer and more accurate. ” Zhang invention, using this method, with the assistance of transparent cap can also complete the treatment of internal hemorrhoids next to the anal papilloma and other diseases. Currently Zhang Invention has applied the technique and treated a number of patients, including his father. “Before treating my father, he told me ‘don’t worry’ and after the operation he told the nurse, ‘don’t be afraid of him, it will be fine, I know he just does things carefully’. It was with gratitude that I wanted to solve his illness at first; but I didn’t realize that he was cooperating with me to complete the trial with the mood of helping his son.” So far, the technology has been used for clinical treatment in several provinces. Just in December 2015, the journal WJGE published Zhang Invention’s new CAES technology with fast-track priority. Just like other treatments, the technique does not solve all hemorrhoid problems, so patients with hemorrhoids should still be evaluated by a medical professional to choose the most appropriate treatment option, Zhang said. But for some hemorrhoid patients who resist surgical treatment, who cannot tolerate surgery, or who have had multiple surgical procedures and whose continued surgery may lead to anal incontinence problems, this offers a new opportunity.
