INTRODUCTION A novel single port access (SPA) cholecystectomy approach is described in this study. We have designed a randomised comparative study in order to elucidate any possible differences between the standard treatment and this novel technique. MATERIALS AND METHODS Between July 2009 and March 2010, 140 adult patients with gallbladder pathologies(More)
BACKGROUND & AIMS Scarce data suggest that cholecystectomy may alter bowel habit. The aim of this study was to determine whether cholecystectomy modifies gut transit. METHODS Five experimental groups were studied: 29 patients with uncomplicated gallstones before and 1 month after elective cholecystectomy, 22 patients 4 years after elective(More)
Objective. Robot-assisted sleeve gastrectomy has the potential to treat patients with obesity and its comorbidities. To evaluate the learning curve for this procedure before undergoing Roux en-Y gastric bypass is the objective of this paper. Materials and Methods. Robot-assisted sleeve gastrectomy was attempted in 32 consecutive patients. A survey was(More)
Introduction. Laparoscopic appendectomy (LA) has been performed in many approaches such as open, laparoscopic and recently Single Port Access (SPAA). In order to elucidate its potential advantages, we compared the two laparoscopic approaches. Methods. 87 patients were included in a multicentric study for suspected appendicitis in order to perform (SPAA)(More)
The trafficking of glycerol from adipose and hepatic tissue is mainly mediated by 2 aquaporin channel proteins: AQP7 and AQP9, respectively. In rodents, both aquaporins were found to act in a coordinated manner. The aim was to study the relationship between adipose AQP7 and hepatic AQP9 messenger RNA expression and the presence of glucose abnormalities(More)
BACKGROUND Although bariatric surgery is the most common procedure used to induce weight loss in morbidly obese patients, its effect on plasma satiety factors (leptin, ghrelin, and apolipoprotein (apo)-AIV) is controversial. The aim of this work was to analyze these parameters before and at different times after surgery. METHODS Plasma was obtained from(More)
Morbidly obese patients (MOPs) are predisposed to developing abdominal wall hernias with the potential complication of small bowel obstruction and other morbidity. We report our experience in treating morbidly obese patients. Hernia prophylaxis has been attempted as a means of decreasing the incisional hernia risk associated with weight loss surgery. The(More)
This study investigated the relationship between the circulating levels of the endothelial cell glycoproteins plasminogen activator inhibitor type 1 (PAI-1), tissue plasminogen activator (TPA), and thrombomodulin (TM) and the major vascular risk factors described in dialysis patients. In addition, the role of these endothelial cell products as independent(More)
BACKGROUND The relationship between C-reactive protein (CRP), nitric oxide (NO), leptin, adiponectin, and insulin growth factor 1 (IGF-1) is poorly defined in morbidly obese patients before and after gastric bypass and, in some cases, is controversial. METHODS We examined the plasma of 34 morbidly obese patients before and 1, 6, and 12 months after(More)
OBJECTIVE Type 2 diabetes (T2DM) and obesity are associated with magnesium deficiency. We aimed to determine whether the presence of type 2 diabetes and the degree of metabolic control are related to low serum magnesium levels in obese individuals. METHODS A) Case-control study: 200 obese subjects [50 with T2DM (cases) and 150 without diabetes (controls)](More)
