Abstract
A ascite é o acúmulo de líquido livre de origem patológica na cavidade abdominal, fenômeno presente em várias doenças da prática clínica. A doença mais associada com ascite é a cirrose hepática. Na sua fisiopatologia destacam-se três teorias que ocorrem sempre em determinado paciente, porém em momentos diferentes de sua doença: vasodilatação, "overflow" e "underfill". O conceito mais moderno sugere que as três teorias estão presentes no mesmo paciente com cirrose, dependendo do tempo de evolução de sua doença. A teoria da vasodilatação estaria presente desde a fase pré-ascítica até a ascite de longa data. A teoria do overflow seria predominante nos primeiros meses de ascite e a teoria underfill explicaria a maioria dos achados em pacientes com ascite por longo tempo. Neste artigo são comentadas em detalhes as várias doenças que produzem ascite, os métodos diagnósticos empregados na pesquisa clínica da ascite, as complicações da ascite e as opções terapêuticas disponíveis. Em cada item é mostrado o grau de evidência (A até C) presente na literatura médica.
The accumulation of free fluid of pathological origin in the peritoneal cavity is named ascites, and, in clinical practice this phenomenon is present in several diseases. The most common cause of ascites is liver cirrhosis. In the pathophysiology of ascites three theories are noteworthy: vasodilation, overflow and underfill. The modern concept suggest that these three theories are present in the same patient with cirrhosis depending on the disease evolution time. The vasodilation theory would be important in the pre-ascitic phase as well as during all the ascites evolution time. The overflow theory would be important in the first months of development of ascites in cirrhosis, and the underfill theory would explain most of the findings in patients with ascites for a long time. This article comments in detailed, several diseases that produce ascites, the diagnostic methods employed in clinical investigation of ascites' complication and therapeutics options available. In each item the evidence grade (A to C) found in medical literature is shown.
