Abstract
Surgery for potentially curable colorectal cancer most commonly involves resection of the primary tumor and regional lymph nodes. However, the site, extent and presentation of disease have an impact on surgical strategy and the use of combined modality therapy. For colon cancer, complex presentations such as obstructing or perforated colon cancer may influence surgical therapy, and issues pertaining to en bloc resection and oophorectomy remain unresolved. For rectal cancer, surgical management may range from local excision to radical resection. Extent of resection and relatively new operative techniques such as coloanal anastomosis with or without a colonic pouch reservoir are directed towards optimizing both oncologic and functional results.
