A condition in which the lower colon is very much larger than normal, because part of the colon above is constricted, making bowel movements impossible.
Abnormal enlargement of the colon due to an accumulation of impacted feces. It may be congenital (Hirschsprung’s disease); acquired (as in chronic refusal to defecate, especially in children); or toxic, a complication of ulcerative colitis. Treatment is by surgery, especially for congenital and toxic forms, and by enemas and laxatives.
Condition of the colon with extreme dilation and hypertrophy.
A distended colon. Symptoms of megacolon include severe constipation. Diagnosis is made by X rays or a lower gastrointestinal (GI) series (also known as a barium enema). In severe cases, surgery is required.
Dilatation, and sometimes lengthening, of the colon. It is caused by obstruction of the colon, Hirschsprung’s disease, or longstanding constipation, or it may occur as a complication of ulcerative colitis (toxic megacolon), Crohn’s disease, or severe bacterial dysentery.
A greatly enlarged colon that may be present at birth or develop later. It can occur in all age groups and the condition is typified by severe chronic constipation. Megacolon is caused by obstruction of the colon, possibly due either to faulty innervation, or to psychological factors. Other causes are hirschsprung’s disease or ulcerative colitis. In old people the persistent use of powerful laxative drugs may cause the condition.
Massive dilation of the colon, which, if left untreated, may result in perforation and peritonitis.
An unusually enlarged colon commonly linked to various chronic intestinal disorders.
A significant enlargement of the colon, typically associated with intense, long-term constipation.
In children, leading causes of megacolon include anal fissures, Hirschsprung’s disease, and mental factors that might surface during potty training. For the elderly, it’s often due to prolonged use of potent laxatives. Individuals with chronic depression or schizophrenia frequently exhibit megacolon. Less common causes encompass hypothyroidism, spinal injuries, and the consumption of drugs like morphine and codeine.
Megacolon results in constipation and abdominal swelling. Some people with this condition might face a reduced appetite, potentially causing weight loss. Diarrhea can arise if semi-liquid stool bypasses the blockage created by solid feces.
The condition is diagnosed using proctoscopy (an endoscopic examination of the rectum), barium X-ray analysis, and tests evaluating the intestinal muscles’ functionality. If Hirschsprung’s disease is a potential cause, a biopsy of the large intestine might be conducted.
Enemas are typically used to clear out impacted stool. In more serious situations, the stool might need to be manually extracted.
An enlarged, expanded colon, also referred to as Hirschsprung’s disease.
