Abstract
Contrast lymphangiography is a useful technique to determine the site of lymphatic leakage in the patient with chylous ascites. Conventional lymphangiography with lipid-soluble contrast material carries the disadvantage of complications, such as oil emboli and lymphedema. The authors report a successful case of computed tomography (CT)-lymphangiography with direct injection of water-soluble contrast medium into a lower limb lymphatic vessel to determine the site of lymphatic leakage in a pediatric patient with refractory primary chylous ascites. The patient subsequently underwent laparoscopic ligation of the leaking site and recovered well. This novel technique offers superior potential for preoperative assessment and the planning of laparoscopic repair.
