Ascites (/ ə ˈ s aɪ t i z /; [5] Greek: ἀσκός, romanized: askos, meaning "bag" or "sac" [6]) is the abnormal build-up of fluid in the abdomen. [1] Technically, it is more than 25 ml of fluid in the peritoneal cavity, although volumes greater than one liter may occur. [4]
The serum-ascites albumin gradient or gap (SAAG) is a calculation used in medicine to help determine the cause of ascites. [1] The SAAG may be a better discriminant than the older method of classifying ascites fluid as a transudate versus exudate. [2] The formula is as follows: SAAG = (serum albumin) − (albumin level of ascitic fluid).
The serum-ascites albumin gradient (SAAG) is the most useful index for evaluating peritoneal fluid and can help distinguish ascites caused by portal hypertension (cirrhosis, portal vein thrombosis, Budd-Chiari syndrome, etc.) from other causes of ascites. SAAG is calculated by subtracting the albumin measure of ascitic fluid from the serum value.
Spontaneous bacterial peritonitis (SBP) is the development of a bacterial infection in the peritoneum, despite the absence of an obvious source for the infection. [1] It is specifically an infection of the ascitic fluid – an increased volume of peritoneal fluid. [2]
In medicine, shifting dullness refers to a sign elicited on physical examination for ascites (fluid in the peritoneal cavity). [1]The two steps of shifting dullness. Percussion of the green section shifts from a dull note to a tympanic note after the patient changes from supine to lateral decubitu
The serum-ascites albumin gradient can help determine the cause of the ascites. [7] The color of the ascitic fluid can also be useful in analysis. Blood fluid can indicate trauma or malignancy. A milky appearance of the fluid can indicate lymphoma or malignant peritoneal ascites. Cloudy or turbid fluid can indicate possible infection or ...

The liver biopsy can also be image-guided, in real-time or not, which is recommended for some clinical situations such as people with known intra-hepatic lesions, previous intra-abdominal surgery who may have adhesions, a small liver that is difficult to percuss, obese people and people with evident ascites.
