  • Recovery from short bowel syndrome (SBS) requires intestinal adaptation, dependent on enteral nutrition (EN) and peptides, like glucagon-like peptide-2 (GLP-2). The purpose of this thesis was to investigate endogenous GLP-2 production and compare elemental versus polymeric formula in a neonatal animal model of SBS. Piglets were assigned mid-intestinal resection (JI); distal-intestinal resection (JC); or to a sham group. Postoperatively piglet’s commenced parenteral nutrition (PN), tapering as EN (elemental or polymeric) was increased. JI piglets had shorter PN duration (p<0.01), longer villi (p<0.01), deeper crypts (p<0.01) and higher plasma GLP-2 (p<0.001). Adaptation did not occur in JC piglets, while polymeric formula increased their duration of PN support (p<0.05) and plasma GLP-2 (p<0.05). This thesis shows that endogenous GLP-2 production is increased in association with adaptation in SBS piglets with ileum (JI). Polymeric formula increased endogenous GLP-2 in piglets without ileum, but did not benefit adaptation in neonatal SBS.
