Mesenteric cysts are rare intraabdominal tumors. We review the diagnosis, laparoscopic management, patient's outcome and follow-up of evaluation for three cases of mesenteric cyst that presented to Istanbul University, Istanbul Medical School, Department of Surgery, from 1999 to 2002. All of the patients presented with nonspecific abdominal symptoms such as constipation, abdominal discomfort, and anorexia. Preoperative evaluation for differentiating mesenteric cyst from malignancy is made by abdominal ultrasound and computed tomography. The procedure was completed laparoscopically using three trocars in three patients. In one patient retroperitoneal resection was performed. There were no intraoperative or postoperative complications. The follow-up periods ranged from 6 to 36 months, and there were no recurrences. Currently, the surgical treatment of mesenteric cyst should be performed by laparoscopy, which offers significant advantages in terms of reduced morbidity and hospital stay. For appropriate cases in which cyst arises from mesenterium of colon, the retroperitoneal approach should be applied.
