Volvulus occurs most frequently in middle-aged and elderly men. [11] 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.
The colon is the longest part of the large intestine and its average length in the adult human is 65 inches or 166 cm (range of 80 to 313 cm) for males, and 61 inches or 155 cm (range of 80 to 214 cm) for females. [11]
Although uncommon in the general population, ischemic colitis occurs with greater frequency in the elderly, and is the most common form of bowel ischemia. [ 1 ] [ 2 ] [ 3 ] Causes of the reduced blood flow can include changes in the systemic circulation (e.g. low blood pressure ) or local factors such as constriction of blood vessels or a blood ...
The true incidence of rectal prolapse is unknown, but it is thought to be uncommon. As most affected people are elderly, the condition is generally under-reported. [22] It may occur at any age, even in children, [23] but there is peak onset in the fourth and seventh decades. [3] Women over 50 are six times more likely to develop rectal prolapse ...
In infants, feeding difficulties and poor weight gain are also frequent symptoms. [6] In some cases of SMA syndrome, severe malnutrition accompanying spontaneous wasting may occur. [7] This, in turn, increases the duodenal compression, which worsens the underlying cause, creating a cycle of worsening symptoms. [8]
Colorectal cancer rates in people under 55 are increasing and it's more advanced. Experts are unsure why, but think diet, exercise and environment play a role. Colon cancer is rising in young ...
The total removal of the colon, called a colectomy or resection of affected parts of the colon may be needed if part of the gut dies (for instance toxic megacolon), or if there is a localized area of dysmotility. Gastric and colonic pacemakers have been tried. These are strips placed along the colon or stomach which create an electric discharge ...
Approximately 5% of people experience smoldering diverticulitis. [54] Diverticulitis recurs in around one-third of people – about 50% of recurrences occur within one year, and 90% within 5 years. Recurrence is more common in younger people, in those with an abscess at diagnosis, and after an episode of complicated diverticulitis. [54]
