Purpose Of Review:
This review will give an overview of current trends in diagnosis, treatment, and pathogenesis of ascites and intraabdominal infection in cirrhotic and noncirrhotic critically ill patients.
Recent Findings:
Single clone-bacterial DNA has been found in sterile ascites and serum, proving the concept of direct translocation. Activation of mesenteric macrophages can be induced by splanchnic vasodilatation but also by hypoxia. Carbon monoxide, an end product of heme catabolism, promotes splanchnic vasodilatation, representing a possible link between gastrointestinal hemorrhage and circulatory dysfunction. Colorimetric test strips and automated counters accurately diagnose spontaneous bacterial peritonitis. Vasopressin V2-antagonists have been introduced as novel therapy for impaired water excretion in hyponatremia.
Summary:
Emerging pathophysiological concepts have modified the conventional view of hydrostatic and Starling forces in the evolution of ascites. Current data indicate that the dynamic sequence of bacterial translocation, mesenteric inflammation, splanchnic vasodilatation and intrahepatic vasoconstriction determines occurrence, severity, and outcome of ascites and intraabdominal infection.
Insights
New insights into ascites and intraabdominal infection reveal bacterial translocation and inflammation drive these conditions in critically ill patients. Diagnosis and treatment strategies are evolving for cirrhotic and noncirrhotic patients.
Area of Science:
- Critical care medicine
- Gastroenterology
- Infectious disease
Background:
- Ascites and intraabdominal infections are common complications in critically ill patients, particularly those with cirrhosis.
- Traditional understanding focused on hydrostatic and Starling forces, but emerging evidence points to complex pathophysiological mechanisms.
Purpose of the Study:
- To review current trends in the diagnosis, treatment, and pathogenesis of ascites and intraabdominal infection.
- To provide an overview for critically ill patients, both cirrhotic and noncirrhotic.
Main Methods:
- Literature review of recent studies on ascites and intraabdominal infection.
- Analysis of pathophysiological concepts, diagnostic tools, and therapeutic interventions.
Main Results:
- Bacterial translocation from the gut is a key factor, evidenced by bacterial DNA in sterile ascites and serum.
- Splanchnic vasodilatation, induced by factors like hypoxia and carbon monoxide, contributes to disease progression.
- Novel diagnostic methods like colorimetric test strips and automated counters improve spontaneous bacterial peritonitis detection.
- Vasopressin V2-antagonists offer new therapeutic options for hyponatremia.
Conclusions:
- Pathogenesis is redefined by bacterial translocation, mesenteric inflammation, and altered splanchnic circulation.
- These dynamic processes, rather than solely hydrostatic forces, dictate the occurrence, severity, and outcomes of ascites and infection.
- Updated diagnostic and therapeutic approaches are crucial for managing these complex conditions in critically ill patients.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
