Small bowel necrosis in association with jejunal tube feeding.

Early recognition and appropriate treatment of bowel ischemia is imperative to reduce morbidity and mortality in any situation, including in conjunction with enteral tube feeding. GI intolerance can manifest as increased nasogastric tube output, unexplained abdominal pain/distension, and pneumatosis intestinalis in critically ill patients who are on tube feedings and may be experiencing periods of splanchnic hypotension. Recommendations are to immediately cease tube feedings when these signs and symptoms are recognized, and total parenteral nutrition should be considered. Surgical exploration during the early stages should be considered to prevent the usual and fatal catastrophic cascade of widespread bowl infarction.
