摘要
The treatment of mid-and low rectal cancer is a challenging issue. Lateral spread of
cancer cells to the pelvic side wall, sphincter preservation technique in a narrow
pelvis, ultra-low ananstomosis, a high local recurrent rate, and unsatisfactory
anorectal function of low anastomosis are all problems which should be solved.
Total mesorectal excision resection is now the standard procedure. Lateral pelvic
side wall lymph node dissection is not widely accepted as a routine procedure
because of high morbidity. Now it is largely replaced by preoperative CCRT
(concurrent chemoradiotherapy). Construction of a colon pouch for ultra-low
anastomosis is well accepted for improvement of anorectal function after resection
for lower rectal cancers.
