Single-center experience with pediatric short bowel syndrome: clinical outcomes based on etiology and anatomical type in a retrospective cohort study

Short bowel syndrome (SBS), a subgroup of intestinal failure, is a condition that occurs after major resection of the small intestine due to congenital or acquired lesions that result in malabsorption [1,2].Throughout the past decades, there have been a variety of definitions for SBS.When evaluating the short bowel, the focus used to be on the length of the small intestine.However, recently, definitions have been based more on the function of the remaining bowel than on the length of the small intestine [3,4].Thus, SBS is generally defined as either requiring parenteral nutrition (PN) for >60 days after small bowel resection or having a remnant small bowel length (RSBL) <25% of that expected for gestational age [5,6].
