To explore the application of laparoscopic technique in the treatment of lymphangioma involving important blood vessels in the abdominal cavity of children.

A retrospective analysis of the clinical data, surgical treatment strategies, surgical time, postoperative recurrence rate and complications of 22 children with intra-abdominal lymphangioma involving important blood vessels admitted to the Pediatric Surgery Department of the Second Hospital of Hebei Medical University from 2003 to 2020.

Among them, 18 cases of complete laparoscopic lymphangioma resection were successful, and 4 cases involved huge intestinal lesions. After lengthening the umbilical incision, the abdomen was removed together with the intestinal tube. The important blood vessels involved included 3 cases of splenic blood vessels, 5 cases of retroperitoneal large blood vessels, and 14 cases of mesenteric blood vessels. The operation time is 50-270 min, (131.40±35.2) min, the intraoperative blood volume is 1-300 ml, (41.84±5.24)ml, the average postoperative recovery time is 3.45 days, and the postoperative hospital stay is 6 to 38 days, (15.54±2.36) days, no incision infection, postoperative pathology reported lymphangioma. 2 cases of postoperative drainage fluid 100-200 ml per day, considering the leakage of lymphatic vessels, were cured after drainage; 2 cases of postoperative B-ultrasound showed a small amount of abdominal effusion, which disappeared after 1 to 3 months follow-up. All children had no recurrence or adhesive intestinal obstruction.

Laparoscopic surgery is a safe and feasible method. The child recovers quickly after surgery. The incision scar is small and beautiful. Especially for the resection of abdominal lymphangioma involving important blood vessels, it has less trauma, good visual field exposure, and safe naked blood vessels.
