Peritoneal lavage in the treatment of acute pancreatic ascites.

A case of intraperitoneal rupture of a pseudocyst associated with ascites is presented. Peritoneal lavage was successful in the initial management and allowed definitive surgery to be performed at a more opportune time. When faced with a case of intraperitoneal rupture of a pseudocyst, peritoneal lavage should be considered as an alternative to emergency surgery.
