Complications of lymphangiomas in children

Abstract

One hundred ninety-three cases of lymphangioma presenting in children were reviewed over a 10-year period. The diagnosis was established before 5 years of age in 87.0%. The distribution of lymphangiomas was: cervical (31.4%), craniofacial (18.9%), extremity (18.9%), trunk (9.2%), intraabdominal (9.2%), cervicoaxillothoracic (4.9%), multiple (3.8%), cervicomediastinal (2.2%), and intrathoracic (1.6%). Of 164 patients undergoing primary therapy, total excision was performed in 77.4% and partial excision in 20.7% with recurrence rates of 11.8% and 52.9%, respectively. Thirty-eight percent of all operations for lymphangiomas were performed for resection of recurrent or residual disease. The incidence of postoperative complications was 31.3%. Forty-four additional procedures were required to manage these complications. Sclerotherapy with 50% dextrose was used as an adjunct in 9.5%. Recurrences were seen after total resection in 17.6% of operations in which 50% dextrose was used and 11.8% in which it was not used. Seroma formation was noted in 3.5% of total resections and 40.0% of resections for recurrent disease in which adjunctive sclerotherapy with 50% dextrose was used. Seromas occurred in 9.8% of wounds in which local drains were used and 3.6% of wounds in which drains were not used. Infectious complications occurred after 6.6% of operations using perioperative antibiotics and 3.5% not using antibiotics. The management of lymphangiomas in children remains a difficult problem. Despite being benign lesions, lymphangiomas are attended by a high rate of morbidity from complications of the disease and its management. Complete excision still offers the best chance for complete cure. Sclerotherapy with 50% dextrose is not beneficial in the management of recurrent disease or postoperative seromas. Local drains and perioperative antibiotics do not appear to diminish the incidence of seromas and infectious complications, respectively.
