Total excision of mesenteric cysts by laparoscopic surgery: report of two cases.

Mesenteric cysts are relatively rare tumors, and most patients present nonspecific abdominal symptoms until developing larger cysts. We report two cases of mesenteric cysts that were totally excised during laparoscopic surgery. The cysts of both patients were located in the mesenterium of the cecum or ascending colon. Under laparoscopy, the cyst was punctured to collect the cystic fluid for cytology and then completely removed without bowel resection. Histological examination revealed cystic lymphangiomas with endothelial cell lining. The postoperative course was uneventful. Laparoscopic treatment of benign abdominal cysts is an alternative safe and less invasive operation.
