If a polyp is detected during a colonoscopy, a physician will typically opt to remove it and have it sent to pathology for examination. Depending on the size, shape, and location of the polyp, the physician may use snare polypectomy or hot biopsy forceps polypectomy to remove the polyp.
Treatment options may involve minimally invasive endoscopic or laparoscopic therapy, surgery, and chemotherapy.
Endoscopic or Laparoscopic Therapy
Small cancer that is in very early stages may be treated with minimally invasive options such as snare polypectomy to remove polyps during a colonoscopy, endoscopic mucosal resection (EMR) or by using laparoscopic surgery.
- Snare Polypectomy: a minimally invasive endoscopic procedure where snares are used to slip over the polyp and upon closer, excise the polyp.
- Endoscopic Mucosal Resection: is a minimally invasive endoscopic procedure to remove tissue from the colon by lifting the lesion by either suction or injection of fluid and then removing the polyp.
- Laparascopic surgery: often referred to as minimally invasive surgery, is performed through several small incisions in the abdominal wall to access the colon to remove cancerous tissue.1
Colonic Self-expanding Metal Stents
The WallFlex Enteral Colonic Stent with Anchor Lock Delivery System is indicated for palliative treatment of colonic strictures caused by malignant neoplasms and to relieve large bowel obstruction prior to colectomy in patients with malignant strictures.
For more invasive cancer your doctor may recommend surgery which may remove a portion of your colon or relieve a blockage to help improve symptoms.
- Partial colectomy is a procedure to remove the cancerous portion of the colon. The surgeon will reconnect the remaining, healthy portions of your colon. 1
- Colostomy is a procedure used when it is not possible to reconnect the remaining portions of the colon. The surgeon will create an opening in the wall of the abdomen to allow for the elimination of body waste into a special bag. 1
- If the cancer is very advanced a surgeon may perform procedures that are intended to relieve your symptoms and help improve quality of life but are not intended to cure the cancer. 1
Chemotherapy uses drugs to destroy cancer cells and is usually given after surgery if the cancer has spread to the lymph nodes. Chemotherapy may also be used before surgery to shrink the cancer before the operation.
