Peking Union Medical College Hospital took the lead in transanal endoscopic microsurgery. What is an anal endoscopic microsurgery? A special proctoscope with a diameter of 4 cm is inserted from the patient's anus into the rectum and inserted from the four channels on the proctoscope. Stereoscopic mirrors and surgical instruments, the doctor completes the tumor under the stereoscopic microscope with the aid of surgical instruments. This is the latest technology for the treatment of rectal tumors pioneered by the Department of Basic Surgery of Peking Union Medical College Hospital - transanal endoscopic microsurgery (TEM). According to Qiu Huizhong, deputy director of the Department of Basic Surgery, TEM was designed and invented by German experts. It was first reported in 1983 and has been in clinical use for more than 20 years. Studies have confirmed that TEM is a safe and effective minimally invasive technique, which has obvious advantages in the treatment of rectal, upper benign and early rectal cancer. Some Western countries and Japanese medical institutions have used TEM as a standard procedure for the treatment of rectal tumors and early rectal cancer diseases. The technology was introduced to Hong Kong in 1995, but it has not been reported in China yet. Compared with the advantages of traditional surgery, Director Qiu introduced that the current surgical treatment of rectal tumors still uses traditional surgical methods: for rectal tumors that are closer to the anus (not more than 4 or 5 cm), transanal resection is generally used, because the operation is On a flat surface, the operation is difficult, and it is easy to remove the tumor without recurrence. For tumors that are farther away from the anus (more than 4 or 5 cm), laparotomy is performed, which is very traumatic and prone to complications after surgery. In recent years, the hospital's first surgical method, the transanal sphincter approach, has a good effect, but the surgical trauma is still large. The newly introduced TEM technology has the following advantages over traditional therapy: First, there is no trauma and no skin incision during surgery. Unlike open surgery, it is traumatic and scarred, and more importantly, it can keep some patients who need to be removed together with the anus with traditional surgical methods. Secondly, it can remove the rectal tumor from any distance from the anus, and because it is operated under the microscope, the surgical field is good and the resection is accurate. It can not only completely remove the tumor, but also leave the ideal resection margin, prevent postoperative recurrence and reduce the recurrence rate. . Third, the average operation time is only one hour. It is obviously shorter than the open surgery. The amount of intraoperative blood loss is very small, generally only 5 to 10 ml. The patient does not need blood transfusion. Fourth, the incidence of surgical complications is low, and the incidence of surgical complications is low due to accurate surgical procedures, minimal trauma, and minimal impact on the patient's general condition. Fifth, high-quality tumor specimens can be obtained during surgery for accurate pathological staging. Sixth, the patient recovered faster than other surgical methods, and the hospital stay was short. The clinical examination has a good effect. The Department of Basic Surgery and Colorectal Surgery of Peking Union Medical College Hospital has been specializing in the surgical treatment of colorectal tumors for many years. The specialization rate of patients admitted to the hospital is over 95%%, and there is a wealth of experience in clinical diagnosis and treatment of colorectal cancer. Since April this year, 8 cases of TEM have been successfully carried out in China. The patients recovered well after surgery and no complications occurred. Initial experience has been accumulated for the future of such operations. Zhang Daye, a 70-year-old Beijing patient, had no inducement of blood in the stool a year ago. The stool often had a small amount of bright red blood. In December last year, he went to Peking Union Medical College Hospital and found that there was a 2 × 3 cm polyp at 7 cm from the anus. The diagnosis was a tubular adenoma of the rectal villus, and the hospital was given a snare. After 3 months, the patient relapsed and went to Peking Union Medical College Hospital again. It was found that a 2×2.5 cm tumor appeared 8 cm away from the anus, and the initial diagnosis was early rectal cancer. The patient's cancer is deep, and it is necessary to open the abdomen to complete such surgery. However, the hospital used the latest technology TEM to perform surgery on patients. Professor Qiu Huizhong, the deputy director of the Department of Basic Surgery, personally assisted the surgeon and assisted by the physician, Lin Guole, and the operation was completed in just one hour. The patient was able to get out of bed 3 days after surgery, and the patient was discharged home 7 days after surgery. The surgery has higher technical requirements for the doctor. Director Qiu said that the technique is mainly suitable for rectal adenomas, early rectal cancer, palliative resection of advanced rectal cancer and other conditions such as benign rectal stenosis and rectal mucosal prolapse. . Because the technical operation is performed on a parallel plane, which is obviously different from laparoscopic surgery, the surgeon needs to operate with a TV screen or a stereoscopic binocular lens. After the tumor is removed, the intracavitary suture is completed in a small space. Physicians need to have extensive experience in traditional rectal surgery and have received TEM professional training in order to be proficient in operational techniques. "Meddy Medical Network"
