Important practical aspects in the management of patients with shot bowel syndrome and intestinal failure

Short bowel syndrome is a gastrointestinal disorder resulting from massive resection of the small intestine. The most common causes of resection are acute mesenteric ischemia, Crohn’s disease, abdominal trauma, adhesive intestinal obstruction, intestinal malignancies, and radiation enteritis. Short bowel syndrome with intestinal failure is characterized by severe malabsorption-m aldigestion accompanied by abdominal pain, diarrhea, dehydration, and progression of protein-energy malnutrition. Many patients with SBS develop long-term clinical complications over time due to altered bowel anatomy and physiology or various therapeutic interventions such as parenteral nutrition and central venous catheterization. This review focuses on the most important aspects of diagnosis, treatment, and prevention of several complications that can occur in this patient population, including macronutrient and micronutrient imbalances, diarrhea, fluid and electrolyte imbalances, metabolic bone disease, biliary disorders, bacterial overgrowth in the small intestine, and complications related to venous access. The main therapeutic strategies for SBS with intestinal failure are: special diet, enteral nutritional support with semi-elemental mixtures, parenteral nutrition, oral rehydration, antimicrobal and antidiarrheal drugs, enzymes. Administration of glucagon-like peptide 2 analog, teduglutide, is clinically effective in reducing dependence on parenteral nutrition and improving quality of life. Management of patients with SBS with intestinal failure is a complex long-term process which requires dynamic clinical and laboratory monitoring.
