BackgroundWe evaluated the results of urgent intralesional bleomycin injection (IBI) treatment of intra-abdominal lymphan-giomas (IAL) presenting with acute abdomen in children.MethodsThe records of patients who underwent urgent IBI due to acutely presenting IAL between January 2013 and January 2020 were reviewed retrospectively in terms of age, presenting symptoms, cyst type, number of injections, pre- and post-treatment cyst volume, clinical response, complications, and follow-up.ResultsSix patients with a mean age of 4.3 years (2-13 years) were treated. Presenting symptoms were acute abdominal pain (n=4), abdominal distention (n=1), hypoproteinemia and chylous ascites (n=1). Lesions were of macrocystic type in four and macro and micro cystic in two patients. The median number of injections performed was 2 (1-11). Mean cyst volume reduced dramatically from 567 cm3 (range 117-1656) to 3.4 cm3 (range 0-13.8) after treatment (p=0.028). Treatment response was excellent in four patients with complete resolution of the cysts, while good in the remaining two. No early or late complications or recurrence was observed in a mean follow-up period of 40 months (16-56 months).ConclusionIBI is a safe, fast, and easily applicable method with satisfactory results in the treatment of acutely presenting IAL. It may be recommended in primary as well as recurrent lesions.
