   Abstract : Gastric bypass achieves weight loss in the morbidly obese. Preoperative weight loss is used to reduce the enlarged fatty liver that otherwise reduces visibility during surgery. The purpose of gastric bypass is to provide patients with long-term weight loss. READ MORE

4. 12. Metabolic Disturbances in Relation to Serum Calcium and Primary Hyperparathyroidism

   Author : Emil Hagström; Per Hellman; Ewa Lundgren; Jonas Rastad; Svante Jansson; Uppsala universitet; []
   Keywords : Surgery; Primary hyperparathyroidism; Parathyroidectomy; Insulin sensitivity; Lipoproteins; Glucose metabolism disorders; Bone density; Calcium; Kirurgi;

   Abstract : Primary hyperparathyroidism (pHPT), characterized by elevated serum levels of calcium and parathyroid hormone (PTH), is associated with a number of metabolic derangements causing secondary manifestations. These include osteoporosis and increased risk of fractures, but also risk factors for cardiovascular morbidity and mortality. READ MORE

5. 13. Clinical Studies on Adrenocortical Tumours using  [11C]-metomidate Positron Emission Tomography

   Author : Joakim Hennings; Per Hellman; Bo Wängberg; Uppsala universitet; []

   Abstract : Adrenal tumours, discovered en passant in patients undergoing radiological examinations for non-adrenal disease, so-called adrenal incidentalomas, have increased dramatically in the recent era of more sophisticated diagnostic modalities such as high resolution multidetector computed tomography (CT) and magnetic resonance imaging (MRI). Furthermore, primary aldosteronism (PA) has been documented in several screening studies as being far more common than previously believed among hypertensive patients. READ MORE

6. 14. Calciumhomeostasis and Vitamin D in Obesity and Preeclampsia

   Author : Hella Hultin; Per Hellman; Ylva Pernow; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium homeostasis; vitamin D; preeclampsia; obesity; parathyroid hormone; Endocrine surgery; Endokrin kirurgi; Kirurgi; Surgery;

   Abstract : Normal physiological functioning is highly dependent of calcium and the concentration range is very narrow. Normal calcium levels are so crucial to survival that the body will de-mineralize bone if the levels are insufficient. A prerequisite for normal calcium uptake is a normal Vitamin D level. READ MORE

7. 15. Endoscopic retrograde cholangiopancreatography : Perforation and long-term outcomes after endoscopic sphincterotomy

   Abstract : Endoscopic retrograde cholangio pancreatography (ERCP) is a commonly used procedure in various disorders of the pancreatobiliary tract. When extracting common bile duct stones (CBDS), the major duodenal papilla is divided using a papillotome to perform an endoscopic sphincterotomy (ES). READ MORE
