Familial polyposis, an inherited (hereditary) condition in which hundreds to thousands of polyps (small growths) form throughout the entire length of the large intestine
The term "laparoscopic" refers to a type of surgery called laparoscopy, which allows the surgeon to complete the operation through very small (5-10 mm) incisions in the abdomen. A laparoscope, a small telescope-like instrument, is placed through a small incision near the navel.
Before doctors can prescribe new medications and treatments, they must be shown to be safe and effective. Colorectal cancerclinical trials allow test the effects of new medications on volunteers with colorectal cancer. The researchers follow a strict protocol and use carefully controlled conditions to evaluate the drugs being developed. The evaluation focuses on how well the drug treats colorectal cancer. Researchers also determine its safety and any possible side effects.

The Three Steps of Laparascopic Total Abdominal Colectomy
Step 1: Positioning the Laparoscope
Once you are under anesthesia, the surgeon will make a small cut (about ½ inch) near the navel. A laparoscope will be inserted into the abdomen through this incision. Images taken by the laparoscope will be projected onto video monitors placed near the operating table.
Once the laparoscope is in place, the surgeon will make four or five more small (5-10 mm) incisions in the abdomen. Surgical instruments will be placed through these incisions.
The colon is a large organ (about 5 feet long) stretching from the small intestine (ileum) to the rectum. Doctors divide the colon into four main sections, ascending (right), transverse, descending (left), and the sigmoid colon, which attaches to the rectum. Your surgeon will carefully free the colon in sections, starting with the rectum and sigmoid colon, and finishing with the ascending (right) colon. The main blood vessels (arteries) that supply blood to the colon will be carefully cut and closed throughout the surgery.
Throughout the procedure, the surgeon will use a paddle-like instrument to hold loops of the intestine up and out of the way. When the entire large intestine is freed, the surgeon will free the right colon from the ileum and then identify the part of the ileum that will be rejoined with the rectum.
Finally, your surgeon will pass a snare-like instrument over the colon to make sure that all of the attachments to the tissue have been cut. This snare-like instrument is designed to hold a wire loop, which is tightened by the surgeon around any remaining tissue growths to remove them. Once this is complete, he or she will enlarge one of the incision sites and pull the colon out of the abdominal cavity.
