Large invasive colorectal cancer resection is radical surgery to the naked eye can see and palpable tumors, including primary tumor and draining lymph nodes were all clear as radical resection. Although surgery to remove lesions, but the naked eye or palpable residual tumors that belong to palliative surgery.
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.
Colorectal surgical options (1) radical cancer surgery
Radical resection of colorectal cancer where the scope should include the possible transfer of intestinal harmony mesangial lymph nodes. On the cancer itself, does not require long segment of bowel resection, but in order to remove the root of mesentery lymph node, you need to mesangial ligation of major blood vessels, for the supply of blood vessels to the total removal of intestines. 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 34 cm proximal to anus door of the rectum, which can be matched to the door to retain the possibility of Wang improved significantly. Middle rectal cancer surgery can keep the door sphincter anus, 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.
Colorectal surgical options (2) colon cancer palliative surgery
Extensive local lesions, estimated complete removal is not easy, but there is 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 belong to palliative surgery.
Colorectal surgical options (3) endoscopic treatment, including endoscopic resection of the colorectal cancer focus, and gradually matured in recent years the rise of the 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. Laparoscopy in colorectal surgery in 1991, is applied to the non-cancer diseases, in reducing blood loss, reduced postoperative pain and is conducive to the recovery of intestinal function has been widely recognized.
Colorectal surgical options (4) a common complication of surgery straight after colon cancer surgery often intestinal motor function disorders, stool frequency increased, often due to sigmoid colon after removal of the solid coordination of delivery of functional constipation caused by the destruction of embryos g tube, colon anastomosis, bowel function often changes, such as increased stool frequency, incontinence. Rectal cancer surgery can have barriers to urinary function, sexual dysfunction.
