摘要

Background and Objectives: Short bowel syndrome (SBS) is a rare and life-threatening disease. Few studies have investigated risk factors for parenteral nutrition (PN)-dependence and death in SBS. Accordingly, the aim of this study was to investigate the risk factors for PN-dependence and long-term mortality in SBS. Methods and Study Design: This retrospective study reviewed and evaluated children and adults who were diagnosed with SBS at King Chulalongkorn Memorial Hospital from October 2005 to January 2015. Age, causes of SBS, length of remnant bowel, type of anastomosis, types of nutrition support, SBS-associated complications, PN-dependence rate, duration of PN-dependence, mortality rate, and causes of death were evaluated. Results: Twenty-two adults and 19 children were reviewed. The median follow-up time was 48 months. At the end of follow-up, PN-dependence rate was 51.2%. The residual colon ≥50% group had a significantly lower PN-dependence rate, with a hazard ratio of 0.36 (95% CI: 0.14-0.93; p=0.03). The most frequent cause of death was infection, with the highest percentage of mortality occurring within the first 2 years after surgery. The mortality rate was 53.8% and the residual colon ≥50% group had a significantly lower mortality rate, with a hazard ratio of 0.36 (95% CI: 0.14-0.88; p=0.03). Conclusions: PN-dependence and death occurred in about half of all patients. Residual colon ≥50% was significantly associated with lower death rate and PN-dependence. The crucial role of colon in continuity as a protective factor should be investigated further in prospective studies.
