Large intestine is one of common malignant tumors in the digestive tract, the main mode of the early spread of direct invasion and lymphatic metastasis. Recurrence after resection surgery leading to failure or cause of death among patients the choice of surgical approach. Colorectal cancer surgery should be based on tumor location, involvement of surrounding tissue, lymph node metastasis, malignancy, biological characteristics, and whether the obstruction, combined with the general conditions of patients and surgical resection decisions. The following are the major colorectal cancer surgery.
(1) methods of colorectal cancer colorectal surgery colorectal cancer radical surgery should include removal of the scope where the intestinal cancer and possible lymph node metastasis in mesangial. Jiu cancer itself, does not require long segment of bowel resection, but the Department of Mo Genbu for removal of the lymph nodes, Department of films need to ligation major vessels supplied this to the intestines Jianggai Quanbu removed. However, the necessary removal of cancer in different parts of different scopes.
In recent years, the widespread use of gastrointestinal stapling, so the location deep in the low anastomosis facilitate operation of the cases have a choice to retain the proximal 3-4 cm of the anal rectum, which can be matched to the possibility of sphincter preservation was increased. Can the middle rectal sphincter preservation surgery, you need to get under the principle of radical surgery, according to the patients general condition, local anatomical conditions, surgery safety, the surgical field exposure and experience of the surgeon decide.
(2) colorectal cancer surgical methods of palliative operation extensive local lesions, complete resection difficult to estimate, but no distant metastasis can do palliative resection. Local lesions are still capable of more extensive resection, but had a distant metastasis, in order to remove the obstruction, the symptoms can also be done to improve palliative resection. Extensive local lesions, adhesions, fixed, has not removed the shortcut to do surgery or surgery to relieve symptoms of lean manufacturing. Have distant metastases or other internal organs such as liver metastasis, while still capable of primary tumor resection according to the specific circumstances of the patient to consider whether the same time removed, of course, also goes to mouth is palliative surgery
(3) colorectal cancer Endoscopic surgical treatment of foci, including endoscopic removal of the colon, the rise in recent years and gradually mature treatment of colorectal cancer, a new method. But not all, including endoscopic resection of colorectal cancer may be that this treatment of early colorectal cancer and more limited.
Endoscopic treatment of colorectal surgery without the need to cut open the belly of the profile, the doctor will be through the abdomen of the "key hole" to replace the traditional "long zipper" for treatment. The greatest benefit of this surgery is postoperative physical function would be restored quickly, after a short period of time to get out of bed.
Laparoscopic technique in 1991 be applied to non-cancerous colon surgery disease, because it can reduce bleeding, reduce postoperative pain and is conducive to the recovery of intestinal function has been widely recognized.
