Underlying etiology determines the outcome in atraumatic chylous ascites.

Abstract

Chylous ascites is an uncommon entity and infectious etiology is the most common cause in developing countries. However, recently, whether there is any change in trend of etiologies in developing countries is not known. In this study, a retrospective analysis of the data of cases of atraumatic chylous ascites was conducted. Twelve patients of atraumatic chylous ascites with a mean age of 35 years were studied and 6 of them were males. The mean duration of symptoms was 9.6 months and the clinical presentation was abdominal distension (12 cases), pain abdomen (10 cases), loss of appetite and weight (9 cases), peripheral lymphadenopathy (4 cases) and fever (3 cases). Etiologies were tuberculosis (3 cases), malignancy (2 cases), radiotherapy related (2 cases), pancreatitis related (2 cases), lymphatic malformation (2 cases) and multifactorial (1 case). Eight improved with conservative measures, 2 were lost to follow up and 2 died. Our outcomes found infectious etiology still as the most common cause of atraumatic chylous ascites. Benign treatable causes could be managed successfully with conservative measures while malignant etiology had a poor prognosis. Underlying etiology determines the outcome in atraumatic chylous ascites.
