• This study was to examine whether 'fit' patients over the age of 50 who require elective surgery for ulcerative colitis are suitable candidates for restorative proctocolectomy, providing that they are continent before operation and that the anal sphincter is preserved in its entirety without stripping of the mucosa or endoanal anastomosis.

  • The epithelium of the anal canal between the anal verge below and the pectinate line above is variously described as anal mucosa or anal skin. (medscape.com)
  • It is a scalloped demarcation formed by the anal valves (transverse folds of mucosa) at the inferior-most ends of the anal columns. (medscape.com)
  • In patients over 50, median resting anal pressure was 88 (range 44-131) cm water before and 80 (47-138) cm water after the operation (NS). (bmj.com)
  • The length of the anal canal is about 4 cm (range, 3-5 cm), with two thirds of this being above the pectinate line (also known as the dentate line) and one third below the pectinate line. (medscape.com)
  • However, in patients with FAP who have had colectomy with ileoanal anastomosis, sulindac or celecoxib may be beneficial in reducing the size and the number of adenomatous polyps in the remaining rectum. (medscape.com)
  • The anal canal is the most terminal part of the lower GI tract/large intestine, which lies between the anal verge (anal orifice, anus) in the perineum below and the rectum above. (medscape.com)

  • The demarcation between the rectum above and the anal canal below is the anorectal ring or anorectal flexure, where the puborectalis muscle forms a sling around the posterior aspect of the anorectal junction, kinking it anteriorly. (medscape.com)
  • Cancers of the rectum (in patients who have had subtotal colectomy with ileorectal anastomosis) have been reported despite treatment with sulindac and celecoxib therapy. (medscape.com)
  • Laparoscopic ultralow anterior resection with colonic J-pouch-anal anastomosis. (nih.gov)
  • In front of (anterior to) the anal canal is the rectovesical fascia (of Denonvilliers), and behind (posterior) is the presacral endopelvic fascia (of Waldeyer), under which lie a rich presacral plexus of veins. (medscape.com)
