Study Notes
Internal gangrene refers to the death of body tissue within an organ due to a lack of blood flow or a serious bacterial infection. It is a life-threatening condition that requires urgent medical attention. Several organs can be affected by internal gangrene, primarily those with reduced blood supply or susceptible to bacterial invasion. The following is a brief discussion on the organs affected by internal gangrene:
Liver
The liver is susceptible to internal gangrene, especially in individuals with poor blood flow or existing liver diseases. In some cases, gangrenous changes may develop in liver segments that already show compromised function. These changes are related to prolonged hepatotoxicity resulting from bacterial colonization in cirrhotic livers. Unfortunately, the prognosis for patients with acute liver gangrene is poor, with a significant proportion dying shortly after diagnosis. However, if detected early and managed promptly, the outcome may be improved.
Intestines
Intestinal gangrene occurs when the intestinal wall loses its nutrient support from the bloodstream. This leads to tissue decay and eventual death. Common causes of intestinal gangrene include ischemia, sepsis, and vasculitis. In rare cases, internal gangrene in the intestines can be triggered by a rare disorder called bacterial synergistic gangrene, where several strains of bacteria act together to destroy healthy tissue.
Kidney
Renal gangrene, also known as renal infarction, occurs when blood flow to parts of the kidney is obstructed, leading to tissue death. This can be caused by various conditions like embolism, thrombosis, or vasculitis. Renal gangrene can cause impaired kidney function and, in extreme cases, complete kidney failure. Treatment options depend on the underlying cause and the severity of the gangrene.
In summary, internal gangrene can affect several organs, including the liver, intestines, and kidneys. Early detection and timely intervention are critical to avoid severe complications and ensure better outcomes.
