Mesenteric Cyst in 22 Cases.

Background: The aim of this study is to retrospectively and multi-centerly examine the clinicopathological features of patients who were operated with the diagnosis of mesenteric cyst, which is a rare cause of intra-abdominal mass in the last 9 years, in the light of the literature.

Methods: The patients were operated due to mesenteric cysts in the general surgery clinics of two Training and Research Hospital between 2010 and 2019; age, gender, preoperative clinical findings, computed tomography (CT) findings, localization of the mass, surgical procedure, morbidity, histopathological results, and follow-up period status were analyzed and reported electronically.

Results: The patients generally applied with the complaints of abdominal pain, palpable abdominal mass, and abdominal distention. Fourteen (63.7%) of the cases were male and 8 (36.3%) were female. The mesenteric cysts were located in the small intestine in 18 cases and colon in 4 cases. In the histopathological examination of the surgical materials, simple cyst was detected in 17 cases, lymphangioma in 4 cases, colon adenocarcinoma, and simple cyst in 1 case. In the postoperative period, superficial surgical site infection developed in 3 patients and morbidity developed in 1 patient due to anastomotic leakage.

Conclusion: Although mesenteric cysts are rarely seen, although most of them are not histopathologically malignant, they can reach large sizes and require extensive surgical operation, and related morbidities can be seen. Therefore, mesenteric cysts should be followed carefully in the postoperative period as well as during the diagnosis and surgical treatment process.
