It is more commonly seen in the elderly, some psychiatric patients or in institutionalised individuals. It is not, however, a part of normal aging. The exact cause remains unknown. Dolichocolon is often an incidental finding on abdominal X-rays or colonoscopy. It is not by itself a disease and as such requires no treatment.
CT-Scan showing a coronal section of the abdomen of an elderly lady with an IPO. The symptoms of IPO are nonspecific. It is not unusual for patients to present repeatedly and to undergo numerous tests. [4] Mechanical causes of intestinal obstruction must be excluded to reach a diagnosis of pseudo-obstruction.
Pseudodiarrhea, also known as hyperdefecation or excess stool, is defined as increased stool frequency (more than three times daily) with a normal daily stool weight of less than 300 g. [ 1 ] Pseudodiarrhea is often associated with rectal urgency and accompanies irritable bowel syndrome , hyperthyroidism , and anorectal disorders such as ...
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 ...
Ogilvie syndrome, or acute colonic pseudo-obstruction, is the acute dilatation of the colon in the absence of any mechanical obstruction in severely ill patients. [1]Acute colonic pseudo-obstruction is characterized by massive dilatation of the cecum (diameter > 10 cm) and right colon on abdominal X-ray.
Sigmoidocele (also known as pouch of Douglas descent) is a medical condition in which a herniation of peritoneum containing loops of redundant sigmoid colon descends (prolapses) into the rectouterine pouch (in females), between the rectum and the vagina. [1] [2] This can obstruct the rectum and cause obstructed defecation syndrome. [3]
Fecal calprotectin, a marker of colon inflammation, may be elevated. Computed tomography of the abdomen is not routinely necessary, but may show thickening or inflammation in the distal colon (sigmoid colon) with associated diverticulosis. Treatment may consist of antibiotics, aminosalicylates (mesalamine), or prednisone. In rare cases, surgery ...
The treatment of fecal impaction requires both the remedy of the impaction and treatment to prevent recurrences. Decreased motility of the colon results in dry, hard stools that in the case of fecal impaction become compacted into a large, hard mass of stool that cannot be expelled from the rectum.
