Volvulus can also arise as a rare complication in persons with redundant colon, a normal anatomic variation resulting in extra colonic loops. [12] Sigmoid volvulus is the most-common form of volvulus of the gastrointestinal tract. [13] and is responsible for 8% of all intestinal obstructions.
A human colon is considered abnormally enlarged if it has a diameter greater than 12 cm [3] in the cecum (it is usually less than 9 cm [4]), greater than 6.5 cm [3] in the rectosigmoid region and greater than 8 cm [3] for the ascending colon. The transverse colon is usually less than 6 cm in diameter. [4] A megacolon can be either acute or ...
The transverse colon is the part of the colon from the hepatic flexure, also known as the right colic, (the turn of the colon by the liver) to the splenic flexure also known as the left colic, (the turn of the colon by the spleen). The transverse colon hangs off the stomach, attached to it by a large fold of peritoneum called the greater omentum.

This typically is associated with anatomic issues such as a redundant sigmoid colon or a transverse colon which prevents complete advancement of the colonoscope to the cecum. During an ELVIS procedure one proceduralist attempts a standard colonoscopy in the operating room with the patient under anesthesia.
Thomas Packard was diagnosed with Stage 4 colon cancer after rectal bleeding, using the bathroom a dozen times a day. He had six months to live. Doctors used HAI to treat him.
The full thickness of the rectal wall is incised at a level just above the dentate line. Redundant rectal and sigmoid wall is removed and the new edge of colon is reconnected (anastomosed) with the anal canal with stitches or staples. [10] This procedure may be combined with levatorplasty, to tighten the pelvic muscles. [7]
