Abstract: Objective：To explore the main points of diagnosis and treatment of mesenteric cyst in children.Methods：A retrospective analysis of the clinical manifestations,diagnosis and treatment data of 10 cases of mesenteric cysts confirmed by surgery and pathology in our hospital from 2011 to 2020.Results：The clinical symptoms of this disease are mostly abdominal masses,abdominal pain,and abdominal distension.Bultrasound and CT examinations can help diagnose and provide a definite location.In this group,1 case of acute abdomen was examined by emergency laparotomy,and 9 cases were clearly diagnosed before operation.There were 8 cases within 6 years of age and 2 cases within 9 years of age.During the operation,there were 7 cases of cysts located in the mesentery,3 cases of cysts were removed by surgery alone,7 cases of cysts and surrounding intestines were removed,of which 2 cases were operated with the aid of laparoscopic surgery.The postoperative pathological diagnosis was mesenteric cyst.Conclusion：In childhood,especially those under 6 years of age,the onset of abdominal masses,abdominal pain,and abdominal distension should be highly suspected.Cysts can be diagnosed with ultrasound,Xray,CT and other routine examination methods.Surgical treatment is the most effective treatment method.,Simple cyst resection is the most ideal surgical method,and laparoscopic surgery has advantages.
