Gastrointestinal obstruction caused by solidification and coagulation of enteral nutrition: pathogenetic mechanisms and potential risk factors

Abstract

Enteral nutrition (EN) is preferred in order to provide nutrition and reduce catabolism in critically ill patients. Recent studies suggest that the use of EN is successful and complications are rare. However, an underestimated mechanical complication of tube feedings seen in critically ill patients is the coagulation and solidification of the EN causing gastrointestinal obstruction. This report describes two clinical cases (1.23% of all cases seen at our clinic) of obstruction and perforation of the small bowel secondary to the solidification of EN. The understanding and early recognition of this potential complication are essential for the prevention and successful treatment of this condition.
