An intestinal abscess is a medical condition in which there is swelling in the colon as a result of pus that has collected in that area of the body. Infection is the most common reason an intestinal abscess develops. Diverticulitis is a relatively widespread disorder and is the most common source of infection responsible for the formation and accumulation of pus in an intestinal abscess. Other sources include Crohn's disease, peritonitis, and pelvic inflammatory disease (PID).
Diverticulitis is a disorder of the digestive system and primarily affects the large intestine, also known as the colon or intestine. Intestinal abscess develops as a result of diverticulitis. However, diverticulitis itself is a direct result of a different medical condition known as diverticulosis. In diverticulosis, pouches known as diverticula develop within the large intestine. The presence of these pockets can cause pain in the lower left abdomen, although many people with this condition do not have any symptoms.
Diverticulum infection leading to intestinal abscess can be due to various complications arising from diverticulosis. Bleeding and tearing are often contributing factors to the development of intestinal abscess. Intestinal obstruction is also a common cause of the infected condition known as diverticulitis. If diagnosed early enough, dietary changes can sometimes help prevent this type of infection.
Peritonitis, or inflammation of the abdominal membrane, is another potential cause of intestinal abscess. Infection or appendicitis are among the most common causes of peritonitis. Physical trauma involving the abdomen also has the potential to cause injury severe enough for an abscess to form. Pancreatitis, Crohn's disease, and pelvic inflammatory disease also increase the risk of developing abscesses.
Abdominal pain accompanied by fever and a general feeling of weakness should be reported to a medical professional immediately. If an intestinal abscess is present, early diagnosis can often prevent some of the more serious complications, including sepsis, from developing an intestinal abscess. Antibiotics are usually prescribed in an effort to clear the infection from the body. Surgical intervention is often necessary to repair the damage caused by the abscess.
Once diagnosed with an abscess, the prognosis will depend on a variety of factors. Some of these include the underlying medical condition leading to the development of the abscess, as well as the patient's general health and response to treatment. Many patients report pain relief as well as an improved quality of life after undergoing treatment for this condition.
