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.
A sigmoidoscopy allows an examination of the distal portion (about 600 mm) of the colon, which may be sufficient because benefits to cancer survival of colonoscopy have been limited to the detection of lesions in the distal portion of the colon.
