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.
The sigmoid colon is the part of the large intestine after the descending colon and before the rectum. The name sigmoid means S-shaped (see sigmoid; cf. sigmoid sinus). The walls of the sigmoid colon are muscular, and contract to increase the pressure inside the colon, causing the stool to move into the rectum.
