Chronic intestinal failure: an overview and future perspectives

Intestinal failure (IF) is the inability of the gut to absorb necessary water, macronutrients, micronutrients, and electrolytes sufficient to sustain life and requiring intravenous supplementation or replacement. IF Types 1 and 2 are the initial phase of this condition and usually last for weeks to a few months. Type 3 IF (also known as chronic IF [CIF]) is a chronic and stable condition, usually irreversible, whose main treatment is home parenteral nutrition. CIF is a relatively rare condition, and its prevalence and different causes vary throughout the world. Due to its complexity, CIF requires a multidisciplinary team with experience in this field to achieve successful outcomes. This editorial aims to provide an overview of CIF in adults, emphasizing the challenges faced by clinicians when managing this rare entity, as well as outlining the role of the gastroenterologist.
