Introduction: elective resection for rectal cancers
Surgical resection of the tumour remains the primary modality to treat rectal cancer. Technological advances have broadened the range of approaches that can be taken to facilitate curative resection of abdominal tumours, and improved understanding of pelvic anatomy has influenced the extent of resection for rectal cancer. These developments have resulted in a number of randomised controlled trials (RCTs) to determine the optimal approach to the elective resection of rectal cancer.
