What is the difference between an incarcerated hernia and a strangulated hernia?

An incarcerated hernia and a strangulated hernia are advanced stages of hernia complications that require medical attention. An incarcerated hernia occurs when a portion of the intestine or fatty tissue protruding through a weakness in the muscle wall becomes trapped and cannot be pushed back into the abdominal cavity with gentle pressure [3]. A strangulated hernia is a more serious condition that occurs when the blood supply to the tissue trapped within the hernia is cut off, which can lead to tissue death [3].

What is an incarcerated hernia?

An incarcerated hernia is a hernia that cannot be manually returned to its normal position inside the abdominal cavity [3]. A person may feel a protruding lump at the hernia site that does not disappear when lying down or applying pressure. Although an incarcerated hernia may not cause severe pain initially, it carries the risk of progressing to a strangulated hernia if left untreated [3]. This type of hernia can occur anywhere in the body, but it often appears in the abdominal area, such as an inguinal or umbilical hernia [1].

What is a strangulated hernia?

A strangulated hernia is a medical emergency that requires immediate surgical intervention. This happens when the blood supply to the tissues trapped within the hernia is cut off [3]. The lack of blood flow can lead to tissue death (gangrene) within a few hours, which is life-threatening [3]. If a strangulated hernia contains a part of the small intestine, it may lead to bowel obstruction and death of the strangulated part of the intestine [3].

Symptoms of a strangulated hernia and when to seek emergency help

Symptoms of a strangulated hernia include the sudden appearance of a larger hernia lump, or a lump that used to return into the abdomen but no longer does so [3]. Other symptoms may include fever, redness at the hernia site, sudden or severe pain or tenderness upon touch in the hernia area, as well as symptoms of bowel obstruction such as abdominal pain, bloating, nausea, and vomiting [3]. If any of these symptoms appear, emergency medical help must be sought immediately, as a strangulated hernia is a life-threatening condition [3].

Treatment options

An incarcerated hernia usually requires surgery to repair it, although men with an inguinal hernia causing little or no symptoms may be able to delay surgery under observation [3]. A strangulated hernia requires emergency surgery to repair the hernia and treat the complications [3]. Several types of hernia surgeries are available, including open surgery and laparoscopic surgery, and the type of surgery recommended depends on factors such as the size of the hernia, the patient's age, and their health condition [3].
