Evaluation of postoperative damage to anal sphincter/levator ani muscles with three-dimensional vector manometry after sphincte

The aim of this study was to examine correlations between pressure profile of the anal canal and postoperative defecatory disorder after sphincter-preserving operation (SPO) for rectal cancer.(Study design) Using three-dimensional vector manometry, pressure profile and length of the anal canal were evaluated more than 1 year after SPO according to operation method and degree o
