What are the surgical treatments for colorectal cancer

In recent years, colorectal cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of colorectal cancer, we humans should master the surgical treatment methods for colorectal cancer:

1. Radical resection of sigmoid colon cancer Depending on the specific location of the cancer, in addition to resection of the sigmoid colon, the descending colon or part of the rectum may be resected. Colocolectomy or colorectal anastomosis may be performed.

2. Abdominal rectal cancer resection (Dixon operation): It is the most commonly used radical resection for rectal cancer. Recent studies have found that rectal cancer rarely infiltrates more than 2 cm downward, so the lower resection margin is required to be 3 cm away from the lower edge of the tumor. With the widespread use of rectal staplers, ultra-low anastomosis can often be successfully performed after resection of rectal cancer 6 cm away from the anal margin, which has expanded the indications for rectal cancer anal preservation resection and improved the anal preservation rate.

3. Radical perineal resection of rectal cancer (Miles surgery): It is suitable for anal canal cancer, lower rectal cancer (the lower edge of the cancer is within 6 cm from the anal edge), or patients with anal incontinence, outlet obstruction constipation, etc. The resection range includes the distal sigmoid colon, the entire rectum, the inferior mesenteric artery and its regional lymph nodes, the entire mesorectum, the levator ani muscle, the fat in the ischiorectal fossa, the skin of the anal canal and about 3 to 5 cm around the anus, subcutaneous tissue and all anal sphincters, and a permanent sigmoid colon single-lumen stoma (artificial anus) is performed in the left lower abdomen. Now there are special artificial anus bags, which are convenient for care and do not affect social interaction and work.

The above is the surgical treatment method for colorectal cancer.
