Radical surgery is a relatively effective method for treating rectal cancer

Radical surgery is a relatively effective method for treating rectal cancer, and there are still many options. Generally, patients can ask their doctors about the treatment of rectal cancer according to their own conditions and choose the surgery that suits them. The specific contents are as follows.

The treatment of rectal cancer mainly includes the following:

First, abdominoperineal resection: Indications: cancer of the lower rectum, where the distance between the lower edge of the cancer and the edge of the anus is less than 7 cm. This surgical excision for rectal cancer includes the entire rectum and its adipose lymphatic tissue in the proper fascia, most of the sigmoid colon and its mesentery and lymphatic tissue, lymphatic tissue at the root of the inferior mesenteric blood vessels before the abdominal aorta, pelvic floor peritoneum, rectal lateral ligaments and levator ani muscles, anal canal, skin around the anus, anal sphincter and adipose lymphatic tissue of the ischiorectal fossa. The blood vessels are ligated and cut at the root of the inferior mesenteric artery or below the branch of the left colic artery, the corresponding para-arterial lymph nodes are cleared, a permanent colostomy and artificial anus are made in the abdomen, and the perineal wound is sutured in the first stage or packed with gauze. This treatment method for rectal cancer is very effective.

Second, anterior resection of rectal cancer: It is mainly suitable for upper rectal tumors more than 12CM away from the anal margin. The sigmoid colon and rectum are removed in the abdominal cavity. The advantages of this method of treating rectal cancer are less traumatic, retaining the anus and good function, and the effect is ideal. This treatment of rectal cancer is not suitable for patients with larger tumors and a wide range of spread and infiltration of surrounding tissues. It is also clinically called low abdominal resection and extraperitoneal primary anastomosis.

Third, anal preservation surgery for rectal cancer: This treatment for rectal cancer is mainly suitable for patients with early rectal cancer whose tumor is 7-11 cm away from the anal margin. Anal preservation surgery for rectal cancer has the advantages of simple operation and short operation time. It also avoids the mental and physical pain brought to patients by permanent artificial anus and many complications caused by artificial anus, and improves the quality of life. Clinically, whether to choose anal preservation surgery is mostly determined based on the pathological type of rectal cancer patients, the size of the tumor, and the degree of infiltration and spread. This method aims to completely cure rectal cancer and has a good prognosis.

Fourth, transanal endoscopic local excision (TEM): It is a new method of local excision of rectal cancer developed in recent years. The surgical indication is patients with T1N0M0. This operation is to perform a local extended excision of the local rectal tumor through an anoscope, using a method similar to surgical laparoscopy, to achieve the purpose of treating rectal cancer. This treatment of rectal cancer can complete the full-thickness resection of the rectal wall. Due to the high requirements for surgical techniques and equipment and the high price, this type of operation is rarely performed in my country.
