Reconstructive rectal surgery.

Rectal cancer causes approximately 6000 deaths in the UK each year. The role of the surgeon in rectal cancer is to control local disease and minimise the risk of recurrence. Reconstructive rectal surgery for cancer aims to combine a safe oncological procedure with the maximum quality of life possible. An improved understanding of rectal cancer pathology allied to modern surgical techniques such as intestinal stapling guns, endoanal anastomoses and the colonic pouch has led to an increased number of sphincter saving operations being performed. We have reviewed the background, technical advances and looked at the future of reconstructive rectal surgery for rectal cancer. Firstly we discuss the work which led to low anterior resection being accepted as an oncologically safe operation. followed by an overview of surgical techniques that have facilitated low anterior resection for rectal cancer with good functional results for the patient. Lastly, we look at the role of radiotherapy and the neosphincter in reducing the need for a permanent stoma.
