Inflammatory bowel disease, or IBD, is the most common initial cause of toxic megacolon. There are two main forms: ulcerative colitis (UC) and Crohn’s disease.
What is fulminant infection?
Fulminant hepatitis is a rare syndrome of rapid (usually within days or weeks), massive necrosis of liver parenchyma and a decrease in liver size (acute yellow atrophy); it usually occurs after infection with certain hepatitis viruses, alcoholic hepatitis, or drug-induced liver injury (DILI).
How long does it take to develop toxic megacolon?
Often, triggering or predisposing factors can be identified. Signs and symptoms of acute colitis may be present for as long as 1 week before dilatation develops.
Can Megacolon be reversed?
Is megacolon reversible? In most cases, megacolon is reversible. This depends on whether it is possible to treat the underlying cause. In acute and toxic megacolon, the underlying cause can usually be treated or otherwise resolves itself naturally, so dilation of the colon is reversed.
Can constipation cause megacolon?
Idiopathic megacolon is a relatively uncommon condition usually associated with slow-transit constipation. Although medical therapy is frequently ineffective, rectal laxatives, gentle enemas, and manual disimpaction can be attempted.
How quickly does toxic megacolon develop?
Toxic megacolon is rare. It’s a widening of the large intestine that develops within a few days and can be life-threatening. It can be a complication of inflammatory bowel disease (such as Crohn’s disease).
Which antibiotic causes toxic megacolon?
difficile) is a gram positive, anaerobic, spore forming bacterium spread by the fecal oral route[1-4]. It produces toxins A and B, causing severe mucosal destruction and pseudomembrane formation[1-5]. Clindamycin, cephalosporins and fluoroquinolones are the most common antibiotics associated with C.
What is toxic colitis with an associated megacolon?
Toxic colitis with an associated megacolon (colonic distention above 6 cm) is often referred to as toxic megacolon or toxic colitis/toxic megacolon (TC/TM). It is a potentially lethal complication of acute colitis, and is defined as total or segmental nonobstructive colonic distention associated with systemic toxicity. [1] Marshak RH, Lester LJ.

What is toxic colitis with dilated colon?
Toxic colitis with dilated colon is referred to as toxic megacolon; dilatation may be segmental or generalized. Toxic colitis can develop without megacolon. An acute presentation from inflammatory or infectious colitis with significant morbidity and mortality.
What is the role of CTCT in the diagnosis of toxic megacolon?
CT is useful in distinguishing patients with toxic megacolon from patients with severe acute colitis, but not toxic megacolon as a complication. The association of air-filled colonic distension greater than 6 cm, abnormal haustral pattern, and segmental colonic parietal thinning seems pathognomonic of toxic megacolon and should lead to rapid
