Result: The mean age of these patients was 45.63 months. The common clinical presentation was abdominal pain (49.4%), a palpable mass (26.5%) and abdominal extension (22.9%). The cysts were intra-operative found in the bowel mesentery, omentum, and retroperitoneal space with the rates were 43.3%; 34.9% and 21.8%, respectively. Total cyst excision was performed in 38 cases (45.8%), simultaneous bowel resection was needed in 26 mesenteric cysts (31.3%), partial cystectomy and sclerosis therapy with Bleomycin was applied in 19 cases (22.9%). There were no perioperative complications in either method of treatment. Subsequently, 13 cases developed recurrence cysts (15.7%); of which, 9 cases had a spontaneous regression without treatment, while 4 cases needed a second intervention included cyst resection and re-do sclerosis therapy. In the retroperitoneal group, the rate of recurrence was 55.5% (10/18 cases). Of the 19 cases who underwent intracystic injection with Bleomycin, recurrence was identified in 8 cases (42.1%).
