title: Sandostatin impairs postresection intestinal adaptation in a rat model of short bowel syndrome.
abstract: Because of its antisecretory properties, sandostatin has been advocated for the treatment of patients with short bowel syndrome (SBS). This study was conducted to determine the effect of sandostatin on structural intestinal adaptation, cell proliferation and apoptosis in a rat model of SBS. Sprague-Dawley rats were divided into three experimental groups: Sham rats underwent bowel transection, SBS rats underwent 75% small bowel resection, and SBS-sandostatin rats underwent bowel resection and were treated with sandostatin (SBS-SND). Parameters of intestinal adaptation, enterocyte proliferation, and enterocyte apoptosis were determined on day 14 following operation. We have demonstrated that SBS-SND animals demonstrated lower (vs SBS rats) duodenal and jejunal bowel weights, jejunal and ileal mucosal weight, jejunal and ileal mucosal DNA and protein, jejunal and ileal villus height, cell proliferation index in the ileum, and enterocyte apoptosis in jejunum and ileum. We conclude that in a rat model of SBS sandostatin decreases cell proliferation and inhibits structural intestinal adaptation.
