Huge Rare Mesenteric Cyst in a 7 years old boy operated successfully.
A mesenteric cyst is an extremely rare, typically benign tumor that develops within the mesentery, the tissue that attaches the intestine to the abdominal wall. They are believed to form due to congenital malformations of the lymphatic system, which causes trapped lymphatic fluid to pool and form a cyst. They are usually formed in the mesentery of the small intestine and very rarely seen to arise from the mesentery of the sigmoid colon (part of large intestine). The presenting symptoms are usually vague abdominal pain, a feeling of fullness, or a palpable, sometimes movable mass in the abdomen. Large cysts can press on nearby organs, leading to nausea, vomiting, constipation, or acute bowel obstruction.
Our patient was a 7 years old boy with history of pain abdomen and abdominal distention for 8 months. On examination, the child’s abdomen was hugely distended with presence of fluid thrill. CT scan of the abdomen showed presence of a large cystic mass occupying the entire abdomen and compressing all other organs. The child was prepared and taken for surgery, intraoperatively the cyst was found to be arising from the mesentery of the sigmoid colon, which is a very rare location for the origin of a mesenteric cyst. The cyst was very meticulously dissected preserving all the blood vessels supplying the sigmoid colon and was successfully removed completely.
Postoperative recovery was uneventful and the child was discharged on 4th postoperative day.
