Decrease in plasma levels of vasoactive intestinal polypeptide in short bowel syndrome: experimental study.
To investigate the behaviour of the vasoactive intestinal polypeptide (VIP) in short bowel syndrome (SBS), an experimental model of massive intestinal resection (MIR) was developed. For this purpose, 20 'minipigs' were divided into two experimental groups: A (control) and B (MIR). The parameters determined were the mean plasma levels of VIP and the degree of steatorrhea at four different times: T1 (basal), T2 (one week after surgery), T3 (two weeks after surgery), and T4 (24 weeks after surgery). The results indicated that, after MIR, a progressive decrease in the mean plasma levels of VIP takes place, with statistical significance in T3 (p < 0.05) and T4 (p < 0.01). This situation seems to be a direct result of the massive loss of intestinal tissue, and could lead to the use of this peptide to mark the evolution of the intestinal adaptation process.
