Data from Decreased Blood Flow with Increased Metabolic Activity: A Novel Sign of Pancreatic Tumor Aggressiveness

Gaber Komar, Saila Kauhanen, Kaisa Liukko, Marko Seppänen et autres

Abstract Purpose: To study blood flow (BF) and metabolism in normal pancreas and in different pancreatic lesions. We then determined the effect of these biomarkers on outcome in patients with pancreatic cancer. Experimental Design: Oxygen-15–labeled water and fluorodeoxyglucose positron emission tomography/computed tomography …

Effect of Laparoscopic Sleeve Gastrectomy vs Roux-en-Y Gastric Bypass on Weight Loss, Comorbidities, and Reflux at 10 Years in Adult Patients With Obesity

Paulina Salminen, Sofia Grönroos, Mika Helmiö, Saija Hurme et autres

Importance: Long-term results from randomized clinical trials comparing laparoscopic sleeve gastrectomy (LSG) with laparoscopic Roux-en-Y-gastric bypass (LRYGB) are limited. Objective: To compare long-term outcomes of weight loss and remission of obesity-related comorbidities and the prevalence of gastroesophageal reflux symptoms (GERD), endoscopic esophagitis, …

Effect of Laparoscopic Sleeve Gastrectomy vs Roux-en-Y Gastric Bypass on Weight Loss and Quality of Life at 7 Years in Patients With Morbid Obesity The SLEEVEPASS Randomized Clinical Trial

Sofia Grönroos, Mika Helmiö, Anne Juuti, Roosa Tiusanen et autres

Importance Laparoscopic sleeve gastrectomy (LSG) is currently the predominant bariatric procedure, although long-term weight loss and quality-of-life (QoL) outcomes compared with laparoscopic Roux-en-Y gastric bypass (LRYGB) are lacking. Objective To determine weight loss equivalence of LSG and LRYGB at 7 years in …

Physical Activity Associates with Muscle Insulin Sensitivity Postbariatric Surgery

Anna Savolainen, Anna Karmi, Heidi Immonen, Minna Soinio et autres

PURPOSE: Bariatric surgery is considered as an effective therapeutic strategy for weight loss in severe obesity. Remission of type 2 diabetes is often achieved after the surgery. We investigated whether increase in self-reported habitual physical activity associates with improved skeletal muscle insulin …

Effect of Laparoscopic Sleeve Gastrectomy vs Laparoscopic Roux-en-Y Gastric Bypass on Weight Loss at 5 Years Among Patients With Morbid Obesity

Paulina Salminen, Mika Helmiö, Jari Ovaska, Anne Juuti et autres

Importance: Laparoscopic sleeve gastrectomy for treatment of morbid obesity has increased substantially despite the lack of long-term results compared with laparoscopic Roux-en-Y gastric bypass. Objective: To determine whether laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass are equivalent for weight loss at …

Accuracy of 18F-FDG PET/CT, Multidetector CT, and MR Imaging in the Diagnosis of Pancreatic Cysts: A Prospective Single-Center Study

Saila Kauhanen, Irina Rinta‐Kiikka, Jukka Kemppainen, Juha Grönroos et autres

UNLABELLED: Accurate diagnosis of the nature of pancreatic cysts is challenging but more important than ever, in part because of the increasing number of incidental cystic findings in the pancreas. Preliminary data suggest that (18)F-FDG PET/CT may have a significant influence on …

Diagnostic performance of 18F-FDG PET/CT, contrast enhanced CT and MRI in cystic pancreatic tumors

Jukka Kemppainen, Saila Kauhanen, Irina Rinta‐Kiikka, Juha Grönroos et autres

1407 Objectives The diagnostic accuracy of combined 18F-FDG PET/CT with contrast enhanced CT (ceCT) was prospectively compared to ceCT and magnetic resonance imaging (MRI) with MR cholangiopancreatography in differentiating malignant and benign pancreatic cysts. Methods Altogether 31 patients with pancreatic cysts were …
