A new sphincter-preserving operation for low rectal cancer: ultralow anterior resection and colorectal/coloanal anastomosis by supporting bundling-up method

PurposeThe introductions of total mesorectal excision and double-stapling technique into colorectal surgery have promoted the clinical application of sphincter preservation. However, for the tumors localized on the middle or lower level of rectum, sphincter-preservation approaches might be problematic in some patients. We introduce in this report a new sphincter-preserving technique for low rectal cancer.
