Laparoscopic Lower Anterior Resection

A laparoscopic lower anterior resection is a procedure that is usually performed for rectal cancer.  Using a laparoscope, which is a small telescopic instrument that is inserted through a very small “keyhole” incision in the abdomen, the part of the rectum containing the tumor is removed without affecting the anus.  The cancer and a margin of normal tissue on either side of the cancer, along with nearby lymph nodes around the rectum is removed.  The colon is then reattached to the remaining part of the rectum.  In this situation, a permanent colostomy is not necessary.  However, if radiation and chemotherapy have been given before surgery, it is common for a temporary colostomy to be made.  Usually this can be reversed about 8 weeks later.
