| [ Summary ] | Rectal cancer surgical procedures have improved over the past two decades. Extended radical procedures to improve curerates have been employed to maintain urinary and sexual functionality. Recently, the highest level of anal preservation, using ISR (intersphincteric resection) has been performed for rectal cancer around the dentate line. Methods anastomosis have improved due to advances in anastomotic devices. Pouch operations using the residual sigmoid colon have improved early postoperative defecation rates. There are some differences in Japan concerning the rules for lymph node dissection classification. N3 and lateral lymph nodes which are classified as regional lymph nodes are classified as distant metastases according to the TNM classification system. There is a huge difference between the two classifications. It is necessary to determine these differences in the near future. | |
