Transanal Surgical Removal of Rectal Tumors
UW Health Colon and Rectal Surgery specialists in Madison, Wisconsin provide comprehensive evaluation and surgical treatment of diseases of the colon, rectum and anus.
Tumors that are within 10 inches (20 centimeters) of the anus are considered to be in the rectum. In general, cancers of the rectum require a radical operation, involving an approach through the abdomen, to remove the majority rectum.
However, in very specific cases, transanal removal of the tumor may be an option. UW Health colon and rectal surgeons offer a multidisciplinary approach to the workup and management of rectal cancers. When a patient has been diagnosed with a very early-stage tumor (identified as a precancerous or early malignant lesion), our surgeons may be able to offer transanal resection, which refers to a surgical procedure through the anal canal.
Transanal Endoscopic Microsurgery for Rectal Tumors
In addition to the traditional transanal procedure, surgeons at UW Health offer transanal endoscopic microsurgery, an operation that uses an operating scope inserted into the anus through which instruments are passed to remove rectal tumors.
Possible Candidates for Transanal Surgery
Fewer than 10 percent of patients are candidates for a transanal removal of a cancerous rectal tumor. UW Health surgeons will help in deciding if this is a viable option for patients.
