    Abstract:
    Background: To demonstrate the value of intranodal lymphangiography (INL) and lymphatic embolization (LE) in management of iatrogenic chylous ascites in children who fail conservative management. Methods and Results: Retrospective review of medical records revealed six patients (four males and two females; age range 11-39 months) who underwent eight INLs and three LEs between 2017 and 2019. In one patient, the leak was visualized and embolized. In three patients, the leak was not visualized and no embolization was done, but drain output decreased and INL was not repeated. In two patients, the leak was not visualized and no embolization was done, but drain output did not decrease and INL was repeated. Repeat INL identified a leak in one patient and targeted LE was done. Repeat INL did not identify a leak in the other patient, but empirical LE was performed at the sites suspicious for leakage after multidisciplinary discussion. INL was able to identify the site of lymphatic leak in two patients (33%). In the three patients who underwent LE (two targeted at the site of identified leak and one empirical at sites suspicious for leak), one (33%) was clinically successful and the other two required surgery to address the lymphatic leak. In three patients, chylous ascites resolved after INL alone with no additional interventions. Three patients developed complications after the procedure, but only one appears to be related to the procedure itself. Follow-up for 13.8 months (13-26 months) revealed no long-term complications or mortality. Conclusion: INL with or without LE is a safe treatment for iatrogenic pediatric chylous ascites. Early utilization before more invasive surgical intervention should be considered in light of the response to INL.
