Colorectal cancer is a common cancer in China. Once colorectal cancer occurs, the most feared thing is that the anus must be removed, which will not only cause abnormal defecation in the future, but also have a certain impact on the patient's work and social life. The doctor said that for patients with "low rectal cancer", there is a new type of "transanal low rectal resection", which allows patients to keep their anus.

Electrotherapy+chemotherapy reduces tumor and keeps anus unobstructed. Mr. Wu, 54, was diagnosed with stage III colorectal cancer last year, with a tumor size of about 5 cm. According to the evaluation of colorectal surgeons in Shuanghe Hospital of the Ministry of Health and Welfare, the tumor was shrunk by electrotherapy and chemotherapy, and then "low anterior resection of anus and rectum" was performed, which successfully helped Mr. Wu to retain his anus and have normal defecation function in the future.

"Transanal low anterior resection of rectum" is a single-hole laparoscopic minimally invasive surgery to disconnect blood vessels, and at the same time, a natural hole laparoscopic surgery is performed to remove tumors with the patient's anus as the opening. Through natural laparoscopic surgery, the patient's anus can be preserved without permanent enterostomy (artificial anus).

The doctor said that in the past, patients with "low rectal cancer" all underwent abdominal and perineal resection, and the wound was about 20 to 25 cm long, which required permanent enterostomy excretion, which not only had the burden of colostomy care, but also had a certain impact on work, activities and social life.

Compared with the traditional combined abdominoperineal resection, laparoscopic surgery has the advantages of less trauma, less bleeding, no inconvenience of artificial anus and incontinence. At present, many traditional laparoscopic operations have further evolved into single-hole laparoscopic operations, which are characterized by reducing the original scattered four to five wounds of 0.5 ~ 1 cm to 1 wound of 0.5 ~ 2 cm.

Women who are equally dedicated are easier to operate than men. The doctor pointed out that the tumor location of low rectal cancer is less than 5 cm away from the anal orifice. Surgery can enter from the anal orifice and directly remove the tumor from the lower edge of the tumor, which can completely remove the tumor, and it has less damage to the nerves in the pelvic cavity and less impact on defecation function. In addition, women's pelvic cavity is larger than men's, so colorectal cancer surgery in the same position is easier than men's. At present, there is a medical insurance subsidy for "transanal low anterior resection", and patients only need to pay for the consumables at their own expense.
