Colorectal Surgery with Transanal Excision procedure is an option for patients needing colon or rectal removal. In this procedure, the surgeon removes the colon or rectum and the surrounding tissue using minimally invasive, robotic or laparoscopic techniques. The bowel ends are hooked back up together. The procedure allows for the functioning of the anal sphincter and eliminates the need for a colostomy bag after surgery.
The major difference between this technique and other minimally invasive colon and rectal surgery is that the bowel is removed from the anus rather than an incision on the abdomen. Additionally, the bowel ends are sutured back together in a hand-sewn fashion rather than using staplers that need larger incisions on the abdomen. Only tiny incisions for robotic tools are made on the abdomen. Thus, there are no large incisions on the abdomen for removal of the specimen or for staplers.
Recovery from the procedure usually involves a one-night stay in the hospital. Recovery from the procedure is typically quicker and more pain-free than other surgical approaches. Most pain felt after any surgery will be from the abdominal incision, which with this technique are minimal. Patients are usually able to walk right after and most do not need to use narcotic pain medication.
