BACKGROUND The purpose of this study was to review the incidence of incidental gastrointestinal stromal tumors (GISTs) in a cohort of morbidly obese patients undergoing laparoscopic sleeve gastrectomy (LSG) or Roux-en-Y gastric bypass (RYGB), analyzing surgery indication, morbidity, and follow-up data. METHODS All cases with incidental GISTs found were(More)
The laparoscopic Roux-en-Y gastric bypass surgery involves some characteristic surgical complications besides the general risks associated with bariatric surgery. The overall risk could be effectively decreased due to the minimal invasive technique,though. The mortality is 0-0.5% and the risk of morbidity varies between 6 and 30%. However, the specific(More)
BACKGROUND The Edmonton Obesity Staging System (EOSS) is a more comprehensive measure of obesity-related diseases and predictor of mortality than body mass index (BMI) or waist circumference. Its application for the selection of obese patients for obesity surgery has been suggested. OBJECTIVES The aim of this study was to determine whether the EOSS can(More)
Dumping syndrome is a long-term postoperative complication of Roux-en-Y gastric bypass procedures. Morphologically, dumping syndrome usually correlates with a dilatation of the gastroenterostomy with accelerated pouch emptying. Conservative therapy includes diet changes, complementary pharmacotherapy and, if symptoms persist, surgical revision. Surgical(More)
INTRODUCTION The established single-anastomosis-duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is based on a sleeve gastrectomy (SG) as the restrictive part of the procedure. Due to preserved pylorus, SG has the disadvantage of a high-pressure system with de novo or worsening of existing gastroesophageal reflux disease (GERD). CASE PRESENTATION A(More)
PURPOSE To date there is a lack of long-term results of anatomic hip stems in the literature. In this context we present our 10-year results with the hip stem "Euroform". METHODS In a retrospective cohort study 90% of the 51 stems implanted in our institute in the years 1993/94 51 stems were reexamined. Of them 39 were implanted cement-free while 11 were(More)
