Chylous ascites, which can lead to peritonitis, intestinal obstruction, metabolic disorder, and even death from pyemia, is a rare complication of abdominal surgery. Currently, first-line treatment involves conservative management, which includes oral diet and total parenteral nutrition (TPN). However, the efficacy of these treatments cannot be guaranteed. For example, single diet control can result in consecutive drainage for up to 1 month, and salvage surgery is required for some invalid cases. Here, we report 6 cases of chylous ascites after abdominal surgery. In addition to diet control, we delivered traditional Chinese herbal medicine (TCHM) twice daily orally. The drainage volume of the chylous fistula showed an obvious decrease 1 day after the TCHM administration and all 6 patients completely recovered within 4 to 8 days (median: 5.5 days). Although relevant data are limited, our cases would suggest that TCHM could play an important role in the management of chylous ascites. However, randomized controlled trials are still needed to confirm its efficacy in a larger population.
