Bowel infarction or gangrenous bowel represents an irreversible injury to the intestine resulting from insufficient blood flow. It is considered a medical emergency because it can quickly result in life-threatening infection and death. [1] Any cause of bowel ischemia, the earlier reversible form of injury, may ultimately lead to infarction if ...
Those with severe ischemia who develop complications such as sepsis, intestinal gangrene, or bowel perforation may require more aggressive interventions, such as surgery and intensive care. Most patients make a full recovery; occasionally, after severe ischemia, patients may develop long-term complications such as a stricture [49] or chronic ...
Non-gangrenous ischemic colitis, which comprises the vast majority of cases, is associated with a mortality rate of approximately 6%. [34] However, the minority of patients who develop gangrene as a result of colonic ischemia have a mortality rate of 50–75% with surgical treatment; the mortality rate is almost 100% without surgical intervention.
Volvulus causes severe pain and progressive injury to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed. [11] Ultimately, this can result in necrosis of the affected intestinal wall, acidosis, and death. This is known as a closed-loop obstruction because there exists an isolated ("closed") loop of bowel.
However, instances with symptoms and signs of a bowel obstruction occur, but with the absence of a mechanical obstruction, mainly in acute colonic pseudo-obstruction, Ogilvie's syndrome. [3] In 2023 the US FDA reported gastrointestinal ileus as an adverse effect of the medication semaglutide , with frequency and causal relationship unknown.
Gangrene is a type of tissue death caused by a lack of blood supply. [4] The feet and hands are most commonly affected. [1] If the gangrene is caused by an infectious agent, it may present with a fever or sepsis. [1] Symptoms may include: [1] a change in skin color to red or black; numbness; swelling; pain; skin breakdown; coolness
Gangrenous necrosis can be considered a type of coagulative necrosis that resembles mummified tissue. It is characteristic of ischemia of lower limb and the gastrointestinal tracts. Both dry gangrene and gas gangrene can lead to this type of necrosis. If superimposed infection of dead tissues occurs, then liquefactive necrosis ensues (wet ...
Gastrointestinal perforation, also known as gastrointestinal rupture, [1] is a hole in the wall of the gastrointestinal tract. The gastrointestinal tract is composed of hollow digestive organs leading from the mouth to the anus. [3]
