Long-term outcomes by a transanal approach to total mesorectal excision for rectal cancer.

Background: The challenge of performing a good total mesorectal excision (TME) dissection, particularly in the distal 1/3 of the rectum, has spurred interest in new techniques. Robotic surgery is advocated by some, and more recently, a "new" approach, the transanal total mesorectal excision, has been popularized to address this problem. While great interest in this technique exists, little long-term outcome data are available.

Quality of Life and Functional Outcome After Transanal Abdominal Transanal Proctectomy for Low Rectal Cancer.

Background: Transanal abdominal transanal proctectomy is a sphincter-preserving procedure designed to avoid colostomy in patients with cancer in the distal third of the rectum. Oncologic outcomes of this procedure have been established. However, data regarding patient satisfaction and quality of life are scant.

True NOTES TME resection with splenic flexure release, high ligation of IMA, and side-to-end hand-sewn coloanal anastomosis.

Introduction: Natural orifice transluminal endoscopic surgery (NOTES) represents the ultimate expression of minimally invasive surgery. We have developed and present here an initial feasibility and safety study of transanal total mesorectal excision (TME) with splenic flexure release, high ligation of the IMA and IMV, and side-to-end coloanal anastomosis with temporary diverting ileostomy for rectal cancer.

Methods: A program of full NOTES TME resection with release of the splenic flexure, high ligation of the IMA/IMV, with side-to-end coloanal anastomosis was performed transanally from December 2013 to July 2014.

Single-port laparoscopic colorectal surgery shows equivalent or better outcomes to standard laparoscopic surgery: results of a 190-patient, 7-criterion case-match study.

Introduction: Single-port (SP) surgery has been characterized as having limited applicability regarding procedure, disease, and patient characteristics. There is a question if SP procedures offer disadvantages or advantages to multiport (MP) colorectal surgery. We hypothesize that SP is equivalent to MP and is a safe alternative in the full spectrum of colorectal disease and procedures.

Quality of life and fecal incontinence after transanal endoscopic microsurgery for benign and malignant rectal lesions.

Background: Transanal endoscopic microsurgery (TEM) is a minimally invasive treatment used to excise a variety of rectal lesions. Potential overstretching of the sphincter's musculature due to dilation of the anal canal to allow placement of a 40-mm-wide scope combined with partial resection of the rectum and subsequent loss of rectal volume creates a concern regarding anorectal function postoperatively. Data regarding patient satisfaction with anorectal function and quality of life after TEM are scant.
