Οι μεταβολές της έκκρισης της Ghrelin και του PYY μετά από χειρουργείο χολοπαγκρεατικής εκτροπής με περιφερική γαστρική παράκαμψη (RYGBP) και άλλες μείζονες χειρουργικές επεμβάσεις

Ghrelin and Peptide YY levels anfter a variant of biliopancreatic diversion with Roux-en-Y gastric bypass versus after colectomy: A prospective comparative study Background. The gastrointestinal peptide hormones ghrelin and PYY, have been shown to play a role in the regulation of metabolism and apetite. We investigate the effect of the biliopancreatic diversion with Roux-en-Y gastric bypass (BPD-RYGBP) procedure on the circulating levels of ghrelin and PYY during the first 3 months postoperatively as compared to the effects of colectomy, an abdominal operation of similar severity. Methods. We determined the fasting plasma levels of ghrelin and PYY in 20 morbidly super obese patients that underwent BPD-RYGBP and in 13 subjects that underwent a colectomy because of large bowel cancer. Fasting plasma ghrelin and PYY levels were measured preoperatively and during the postoperative period on days 1,3,7,30 and 90 in all patients of both groups and at the 1 year for the patients who
