Abstract

Local control of rectal cancer and patient survival have improved remarkably with advances in surgical techniques and adjuvant therapy. By applying advanced surgical principles, surgeons can now excise most rectal cancers completely, often preserving the anal sphincter and leaving the patient with relatively normal bowel and pelvic function. Historically, the earliest surgical approaches to rectal cancer were via the perineum. As surgical techniques and general anesthesia improved, other approaches such as a posterior approach were undertaken to improve access to the whole rectum. Consequently, abdominoperineal resection became the standard treatment until anterior resection was introduced for proximal rectal cancers. The most important surgical breakthrough in recent years has been the advent of total mesorectal excision (TME). The emphasis in rectal cancer surgery is on preservation of function, with dissection being done in appropriate anatomical planes. Thus, mobilization of the rectum has a long history, and is seen in modern procedures including TME and intersphincter resection. This article reviews the progression of the surgical management of rectal cancer with reference to historical perspectives. We discuss the major surgical considerations for mobilization of the rectum in several surgical procedures, from conventional operations to modern standardized TME.
