The short bowel syndrome with intestinal failure (SBS-IF) is a rare but devastating medical condition. An absolute loss of length forces the patients into parenteral support (PS) dependency and variety sequalae resulting in increased morbidity mortality. Interdisciplinary treatment may include therapy effective, expensive intestinotrophic peptide teduglutide. A time-discrete Markov-model was developed to simulate effect (lifetime-costs, quality-adjusted life-years (QALYs) (LYs)) teduglutide...
