About us Our impact Surgical development for rectal cancer Our support for the development of a novel surgical technique, called the APPEAR procedure, enabled surgeons to carry out surgery for low rectal cancer without damaging the patient's anal sphincter, and thereby avoiding a permanent colostomy. The APPEAR technique paved the way for the development of TaTME, a groundbreaking minimally invasive surgical treatment for rectal cancer which preserves bowel function and reduces the likelihood of a permanent colostomy. A systematic review of the procedure was published in the British Journal of Surgery in 2016. The rate of permanent colostomy was 5%. The review's conclusion was that the technique offers a good outcome for selected patients. Dee Herbert was one of the first patients to undergo the procedure. Patients from around the world can still be assessed for the APPEAR at the Royal London Hospital. If you would like to be considered, contact Deborah.
