The effect of chronically increased intra-abdominal pressure on rectus abdominis muscle histology an experimental study on rabbits.

Background: The aim of this study was to specify the histologic response of the rectus abdominis muscle of the rabbit, to the chronically increased intra-abdominal pressure.

Materials And Methods: Forty-five New Zealand white rabbits were divided into three groups. In all groups, a rubber bag was implanted into the peritoneal cavity.

Serum ghrelin, leptin and adiponectin levels before and after weight loss: comparison of three methods of treatment--a prospective study.

Background: Ghrelin is a peptide hormone with orexigenic properties, primarily produced by the stomach. Leptin and adiponectin are the two adiposity products that participate in body weight control. Leptin always decreases and adiponectin increases after weight loss.

Prader-Willi syndrome-associated obesity treated by biliopancreatic diversion with duodenal switch. Case report and literature review.

Background: Prader-Willi syndrome (PWS) is a congenital chromosomal disorder characterized by compulsive hyperphagia and the early development of obesity. Obesity is identified as the main cause of morbidity and mortality in PWS individuals. Thus, body weight reduction is of major importance for a prolonged survival.

The effect of biliopancreatic diversion with pylorus-preserving sleeve gastrectomy and duodenal switch on fasting serum ghrelin, leptin and adiponectin levels: is there a hormonal contribution to the weight-reducing effect of this procedure?

Background: Ghrelin is a peptide hormone with orexigenic properties, primarily produced by the stomach. Different changes in fasting ghrelin levels have been reported following bariatric surgery. In this study, we investigate the hypothesis that because ghrelin is mainly produced by the fundus of the stomach, biliopancreatic diversion with sleeve gastrectomy with total resection of the gastric fundus and duodenal switch (BPD-DS) will cause substantial decrease in circulating ghrelin levels.
