As such, surgical intervention is preferred and, with complete resection, offers an excellent prognosis. Two independent studies reported recurrences in 10% of patients in whom primary resection was incomplete.1-2 Chylous ascites may occur if the stem of the cyst and feeding lymphatics are unsuccessfully ligated.3 Management of this condition may include the placement of drains as they facilitate the injection of fibrinogen and thrombin, especially when drainage is persistent.4
