Internal hernia

Internal Hernia

Internal hernia (in-ter-nal her-ni-a) is a type of hernia that occurs when an organ or tissue protrudes through a defect within the muscles of the abdominal wall, into the peritoneal cavity. It is a rare cause of intestinal obstruction.

Etymology

The term "hernia" is derived from the Latin word "hernia", which means "a rupture". The prefix "internal" is derived from the Latin word "internus", which means "inside".

Types of Internal Hernia

There are several types of internal hernias, including:

• Paraduodenal hernia: This is the most common type of internal hernia. It occurs when part of the small intestine herniates into the paraduodenal fossa, a potential space behind the first part of the duodenum.

• Foramen of Winslow hernia: This is a rare type of internal hernia that occurs when part of the intestine herniates through the foramen of Winslow, an opening between the stomach and the liver.

• Transmesenteric hernia: This type of hernia occurs when part of the intestine herniates through a defect in the mesentery, the tissue that connects the intestines to the back of the abdominal wall.

Symptoms

Symptoms of an internal hernia can vary, but may include:

• Abdominal pain
• Nausea
• Vomiting
• Bloating
• Constipation

Diagnosis

Diagnosis of an internal hernia is often challenging due to its nonspecific symptoms. It is usually confirmed through imaging studies such as Computed Tomography (CT) scan or Magnetic Resonance Imaging (MRI).

Treatment

Treatment for an internal hernia usually involves surgery to reposition the herniated organ and repair the defect in the abdominal wall. This can be done through open surgery or laparoscopic surgery.
