Defining gastrointestinal failure.

Area of Science:

• Critical Care Medicine
• Gastroenterology
• Pathophysiology

Background:

• Gastrointestinal failure (GIF) is proposed as a primary driver of multiple organ dysfunction syndrome (MODS).
• Current scoring systems for MODS often exclude gastrointestinal dysfunction.
• Lack of a standardized definition hinders GIF's recognition and integration into clinical practice.

Purpose of the Study:

• To review and analyze the existing literature on gastrointestinal failure (GIF).
• To highlight the variability in definitions and assessments of GIF.
• To emphasize the need for a standardized, function-based definition of GIF.

Main Methods:

• A comprehensive literature search was conducted using PubMed.
• Analysis focused on English-language articles and reviews concerning gastrointestinal problems.
• Key findings regarding GIF definitions, incidence, and impact were synthesized.

Main Results:

• Significant heterogeneity in terminology and definitions of GIF was identified.
• Controversial data exists regarding the incidence of GIF and its association with mortality in critically ill patients.
• Existing definitions are largely diagnosis-based rather than function-based, unlike other organ failure assessments.

Conclusions:

• There is a lack of consensus on the definition of GIF across different medical specialties.
• Current diagnosis-based approaches to GIF are inadequate and differ from function-based assessments of other organ failures.
• A universally accepted, function-based definition for GIF is urgently needed for clinical application and research.
