2. 1. Intestinal Bypass and Total Parenteral Nutrition: Changes in Gut Function and Morphology

   Author : Mikael Ekelund; Lund Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; Surgery; Gastroenterologi; Gastro-enterology; Fysiologi; Physiology; total parenteral nutrition; supersensitivity; plasticity; intestinal bypass; interstitial cells of Cajal; goblet cells; eosinophils; adaptation; enteric nervous system;

   Abstract : Abolition of enteral nutrition is sometimes required in severe illness. The primary aim of the present work has been to elucidate possible changes in intestinal morphology and motor function in absence of enteral nutrition. Total absence of enteral nutrition in an isolated intestinal segment was created by bypassing the distal ileum in a rat model. READ MORE

4. 2. Intestinal adaption in response to Roux-en-Y gastric bypass surgery

   Author : Erik Elias; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; obesity; bariatric surgery; proteomic analysis; intestinal permeability; calcium; bone mineral density; lipid metabolism;

   Abstract : ABSTRACT Background: Obesity is a condition with increasing prevalence that leads to morbidity, decreased quality of life and reduced life expectancy. The only effective evidence-based treatment is bariatric surgery. READ MORE

5. 3. Aspects on the functional characteristics of the Roux-limb after Gastric Bypass surgery

   Author : Per Björklund; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; obesity; bariatric surgery; meal size; morphology; intestinal motility; high resolution manometry; abdominal pain; opioid analgesics;

   Abstract : Background: Bariatric surgery, and particularly the Roux-en-Y Gastric Bypass (RYGBP) procedure, has highlighted the central role of the gastrointestinal tract in the regulation of body weight and metabolism. The Roux-limb is the part of the small intestine that has become the food recipient after RYGBP and has generally been very little studied. READ MORE

6. 4. Splanchnic perfusion in cardiac surgery

   Author : Anders Thorén; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Splanchnic circulation; jejunal mucosal perfusion; laser Doppler flowmetry; cardiopulmonary bypass; cardiac surgery; inotropic agents; gastric tonometry; sympathetic reflex;

   Abstract : Splanchnic ischemia in cardiac surgery is considered a risk factor in the development of the Multiple Organ Dysfunction Syndrome (MODS), which is the leading cause of morbidity and mortality in the intensive care unit. Splanchnic ischemia/reperfusion may lead to an injury of the intestinal mucosa and induce a systemic inflammation (SIRS), which is proposed to precede MODS. READ MORE

7. 5. Vasopressors and intestinal mucosal perfusion. Studies in cardiac surgical and critically ill patients

   Author : Andreas Nygren; Göteborgs universitet; []
   Keywords : ;

   Abstract : During trauma, surgery and critically illness, splanchnic ischemia and reperfusion damage maythreaten the barrier function of the intestinal mucosa, leading to bacterial translocation, immuneactivation and subsequent development of systemic inflammatory response syndrome. Detection,prevention and treatment of intestinal mucosal hypoperfusion are therefore important forprevention of complications in critically ill patients. READ MORE
