What are the specific surgical treatments for colorectal cancer?

Surgery has a good effect in the treatment of colorectal cancer. Surgery has a certain degree of safety and radicality. Many patients do not know much about the treatment of colorectal cancer . Let's take a look at the experts' introduction to the treatment of colorectal cancer, hoping it will be helpful to you.

Surgery as a treatment for colorectal cancer mainly includes the following:

1. Radical surgery : Radical surgery or absolute radical surgery refers to the complete removal of the tumor and the removal of regional lymph nodes during surgery, with no residual cancer at any of the resection margins as determined by histological examination.

2. Local resection : Local resection refers to the resection of part of the intestinal wall in the area where the tumor is located. It is suitable for early superficial colon cancer and benign tumors that are limited to the mucosa or muscularis mucosa. Some malignant tumors located in the muscularis mucosa and the submucosa, among which a few cases may already have regional lymph node micrometastasis and metastasis, may not meet the requirements of radical cure by local resection alone. Such cases should be treated with caution. The resection range of local resection can include the entire layer of the intestinal wall, and the cutting edge should be no less than 2 cm away from the tumor. It is also possible to perform mucosal resection through endoscopy, or to perform resection of the mucosa, submucosa and part of the muscularis mucosa through anal dilation.

3. Palliative tumor resection : Absolute palliative tumor resection refers to those with residual tumor visible to the naked eye. For example, if there is metastasis to the peritoneum, liver, and non-regional distant lymph nodes, it is impossible to remove all metastatic lesions. Relative palliative tumor resection (or relative radical surgery) is a radical procedure. Although the tumor is completely removed by naked eye during the operation, postoperative histology confirms that there is a resection margin, residual tumor base, or metastasis in the highest level lymph nodes removed.

4. Bowel segment resection : Bowel segment resection refers to the removal of a certain length of intestinal tube including the tumor. Generally, the upper and lower cutting margins should not be less than 5.0 cm from the tumor. Tumor bowel segment resection should include corresponding mesangial resection, that is, to meet the DL requirement. It is suitable for larger benign tumors and cancers that are partially limited to the submucosal and superficial muscle layer and have no lymph node metastasis.

5. Combined organ resection : Combined organ resection for colon cancer is suitable for cases where adjacent organs are invaded, and is often used as a radical surgical procedure. However, in some cases, such as when the tumor invades other organs, obstruction or perforation may occur, or internal fistula has formed, and the patient has a long survival expectation after surgery, palliative combined organ resection can still be performed even if distant dissemination has occurred.
