Surgical treatment of colorectal cancer

Colorectal cancer treatment method of radical surgical treatment still proves the most so far.

The 1st National Conference on colorectal cancer, invasive colorectal cancer following radical surgical resection is defined as when the naked eye can see, and palpable tumors, including the primary tumor and draining lymph nodes were all clear for the radical resection, surgery, been able to resection of lesions, but the naked eye or palpable residual tumors belong to palliative surgery. Therefore, lesions confined to the primary or regional lymph nodes should be radical surgery; localized lesions extensive, it is estimated the total excision is not easy, but there is no distant metastasis can be used for palliative resection; local lesion wider still capable of excision, but has have distant metastasis, in order to lift the obstruction, the symptoms can also be made to improve the palliative resection; localized lesions extensive adhesions, fixed, has not removed, can be used as shortcut to making rash surgery or surgery to relieve symptoms; had distant metastasis, such as liver metastasis , or other internal organs shift, while still capable of the primary tumor resection may be considered according to the specific patient is also removed, of course, also goes to belong to palliative surgery.

After surgery syndrome: straight, colon cancer after surgery often gut motor function disorders, increased frequency of stool; sigmoid colon resection often due to the coordination function of solid delivery of the destruction caused by constipation; anal, colon anastomosis often changes in bowel function, such as the increased frequency of bowel incontinence. Urinary function after rectal cancer surgery often barriers to sexual dysfunction. Non-reserved to the anus of the patient, research and design are placed in the perineum of the "artificial anus," and to have control over large toilet device is intended to address the patient's bowel problems. The application is currently studying the muscles of the sphincter muscles instead of exciting technology seems to be promising approaches.
