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).
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] Ascites is most commonly a complication of cirrhosis of the liver. [1]
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.
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]
Primary peritonitis is the diffuse bacterial infection of the peritoneum while the integrity of the gastrointestinal tract is preserved (in cases of ascites); secondary peritonitis is the infection of peritoneum where the integrity of gastrointestinal tract is compromised; tertiary peritonitis is reinfection of peritoneum 48 hours after ...
Peritonitis is inflammation of the localized or generalized peritoneum, the lining of the inner wall of the abdomen and cover of the abdominal organs. [2] Symptoms may include severe pain, swelling of the abdomen , fever, or weight loss.
The ongoing symptoms make Porter and other patients worry they've developed a secondary infection. However, subsequent COVID-19 tests have been negative, and other diagnostic screenings have been ...
The clinical manifestations of secondary peritonitis are a reflection of the underlying disease process. Fever, diffuse abdominal pain, nausea and vomiting are common. Physical examination generally show signs of peritoneal inflammation, isuch as rebound tenderness, abdominal wall rigidity and decrease in bowel sounds.
