An omphalomesenteric cyst is a rare congenital malformation that occurs when the omphalomesenteric duct, which connects the midgut to the umbilical cord during fetal development, fails to close. This results in a cyst that is filled with fluid and can be found in the abdomen or umbilical area. Treatment typically involves surgical removal of the cyst.

The most common symptom of an omphalomesenteric cyst is a lump in the abdomen. Other symptoms may include abdominal pain, nausea, vomiting, and fever. In some cases, the cyst may cause a blockage in the intestines, leading to constipation, abdominal distention, and abdominal tenderness.

Omphalomesenteric cysts are caused by a failure of the omphalomesenteric duct to close during fetal development. This can be due to a variety of genetic and environmental factors, including chromosomal abnormalities, maternal infections, and exposure to certain medications or toxins.

The treatment for Omphalomesenteric cyst depends on the size and location of the cyst. Small cysts may not require any treatment, while larger cysts may require surgical removal. In some cases, the cyst may be drained or aspirated to reduce its size. In some cases, the cyst may be removed laparoscopically, which is a minimally invasive procedure. In more severe cases, the cyst may need to be removed through open surgery.

At this time, there is no known cure for omphalomesenteric cyst. Treatment typically involves surgical removal of the cyst and any associated organs or tissues. In some cases, medications may be prescribed to reduce inflammation and pain.
