Meta Analysis Comparative Study
Does previous transanal excision for early rectal cancer impair surgical outcomes and pathologic findings of completion total mesorectal excision? Results of a systematic review of the literature.
Transanal excision (TAE) is increasingly used in the treatment of early rectal cancer because of lower rate of both postoperative complications and postsurgical functional disorders as compared with total mesorectal excision (TME) OBJECTIVE: To compare in a meta-analysis surgical outcomes and pathologic findings between patients who underwent TAE followed by completion proctectomy with TME (TAE group) for early rectal cancer with unfavorable histology or incomplete resection, and those who underwent primary TME (TME group). ⋯ This meta-analysis suggests that previous TAE impaired significantly surgical outcomes and pathologic findings of completion TME as compared with primary TME. First transanal approach during completion TME might be evaluated in order to decrease technical difficulties.
