Origin of the name Sydney: Transferred use of the surname originating as a Norman baronial name taken from the place-name St. Denis in Normandy. Alternatively, the name arose independently in England and is derived from the Old English elements sÄ«d (extensive, wide) and ieg (island in a river, riverside meadow).
Sigmoidectomy surgery for inflammatory bowel disease (IBD) Sigmoidectomy surgery removes all or part of the sigmoid colon - the S-shaped part of the large intestine just before the rectum. Where possible the two healthy ends of the intestinal tract are then rejoined. If this is not possible then a stoma may be formed.
Sigmoidoscopy is a less invasive alternative to the traditional colonoscopy procedure. It is performed by gastroenterologists, proctologists and other medical doctors as a routine test to screen for colon cancer for monitoring for healing in patients with IBD.lthough the sigmoidoscopy procedure is very similar to colonoscopy, sigmoidoscopy is a limited colorectal examination, allowing only the lower third of the colon to be viewed, as opposed to the entire large intestine.
