Two Cases of Atraumatic Chylous Ascites Characterized by Hypotriglyceridemia and Partially Managed with an Oral Fat-Free Elemental Diet

Most cases of chylous ascites occur after surgery, but it also develops in nonoperative cases, although rarely. Such cases are often difficult to treat. In this study, we treated 2 cases of atraumatic chylous ascites, which were controlled by combining diuretic treatment with an oral fat-free elemental diet (Elental®, EA Pharma Co., Ltd., Tokyo, Japan). Elental can provide oral nutrition compatible with a lipid-restricted diet, which may be useful for control of chylous ascites. We report on these cases, including literature review-based considerations.
