This document discusses ascites, a pathological accumulation of fluid in the abdominal cavity. It begins with historical references to ascites from ancient Greece and Mesoamerica. The document then covers the causes, clinical findings, diagnostic workup and treatment of ascites. The most common cause is cirrhosis, accounting for around 85% of cases. Diagnostic paracentesis is used to analyze ascitic fluid and determine if it is a transudate or exudate. Treatment involves dietary changes, diuretics, serial paracentesis and sometimes liver transplantation. Complications like spontaneous bacterial peritonitis are also discussed.
