BACKGROUND Aiming to clarify the mechanism of weight loss after the restrictive bariatric procedure of sleeve gastrectomy (LSG), the volumes and pressures of the stomach, of the removed part, and of the remaining sleeve were measured in 20 morbidly obese patients. METHODS The technique used consisted of occlusion of the pylorus with a laparoscopic clamp(More)
UNLABELLED We combined (18)F-FDG PET and CT enterography in a single examination and compared the level of (18)F-FDG uptake measured by maximal standardized uptake value (SUVmax) with the CT enterography patterns of disease activity found in patients with Crohn disease (CD). METHODS Twenty-eight patients (mean age, 37.5 y; 11 male and 17 female) suspected(More)
BACKGROUND Positron emission tomography (PET) combined with Computerised Tomography (CT) is gaining ground in clinical settings due to its added value of combined metabolic and anatomical imaging. PET/CT has shown promising results in diagnosing both acute and chronic infection of the axial and appendicular skeleton. PET imaging has an advantage in patients(More)
BACKGROUND AND AIMS The diagnosis of patients with fever of unknown origin (FUO) remains a challenging medical problem. We aimed to assess the diagnostic contribution of 18-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET)/computed tomography (CT) for the evaluation of FUO. METHODS We performed a 4-year retrospective single-center study of(More)
OBJECTIVE The purpose of this article is to illustrate the spectrum of common benign intraarticular and extraarticular disorders associated with focal (18)F-FDG uptake in the shoulder and pelvic areas in oncology patients referred for PET/CT. CONCLUSION A wide spectrum of benign musculoskeletal disorders associated with focal FDG uptake may be detected in(More)
BACKGROUND In recent years, laparoscopic sleeve gastrectomy (LSG) as a single-stage procedure for the treatment of morbid obesity is becoming increasingly popular. Of continuing concern are the rate of postoperative complications and the lack of consensus as to surgical technique. METHODS A prospective study assessment was made of 120 consecutive morbidly(More)
BACKGROUND Obesity is associated with a poor anesthetic risk, in part because of the greater aspiration rates. A greater gastric residue and lower stomach pH have been implicated. The relationship of obesity to gastric emptying is ill-defined. with contradicting reports stating shorter, similar, and longer times compared with nonobese subjects. The aim of(More)
BACKGROUND The aim of this study is to clarify whether laparoscopic sleeve gastrectomy (LSG) to treat morbid obesity causes changes in gastric emptying. METHODS Gastric emptying scintigraphy was performed before and 3 months after LSG, in 21 consecutive morbidly obese patients. After an overnight fast, subjects consumed a standard semi-solid meal, to(More)
The exact incidence of extra-cardiac complications (ECC) in patients with infective endocarditis (IE) is unknown but presumed to be high. These patients, although mostly asymptomatic, may require a more aggressive therapeutic approach. (18)fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) is used for the diagnosis of(More)
Repeated imaging with positron emission tomography-computed tomography (PET-CT) is associated with cumulative exposure to substantial doses of radiation. Furthermore, PET-CT is an expensive and limited resource in many institutions. We conducted a retrospective analysis to evaluate whether limited PET-CT focused on the initially involved field of view (FOV)(More)
