Laparoscopic enucleation of a jejunal mesenteric cyst: a case report.

Mesenteric cysts (MC) are a rare surgical condition occurring approximately in 1/200.000-350.000. The aetiology is unknown and the rarity of the tumor has led to confusion about their nature and classifi cation. They can be uni- or multi-locular, and are mostly benign. Approximately 830 cases have been reported in the literature and only four of them were found to be malignant. Cysts are usually diagnosed during routine abdominal examinations, they can present with various signs, such as acute abdominal pain, chronic abdominal pain, nausea and vomiting, or change in bowel habit. Although rare, shock due to rupture or bleeding of the cyst, intestinal obstruction secondary to external compression and volvulus or torsion of the cyst have been reported. Defi nitive treatment requires complete surgical resection of the cyst and is indicated when the lesion causes symptoms. We report a case of calcifi ed MC which was completely excised using the laparoscopic approach.
