Context: Fibroblast growth factors (FGF) 19 and FGF21 are secreted by the intestine and liver in response to macronutrient intake. Intestinal resection and reconstruction via bariatric surgery may alter their regulation. Objective: We tested the hypothesis that weight loss induced by Roux-en-Y gastric bypass (RYGB) surgery, but not matched weight loss induced by laparoscopic adjustable gastric banding (LAGB), increases postprandial plasma FGF19 and FGF21 concentrations...

PURPOSE: Dumping is currently seen as a negative side effect of Roux-en-Y gastric bypass (RYGB). However, it may help patients to comply with their prescribed diet. In this study, we assess the role of dumping on weight loss in patients who have undergone conversion of failed restrictive surgery into RYGB. METHODS: An analysis was performed of 100 consecutive patients who underwent revisional RYGB (rRYGB) between 2006 and 2011 due to inadequate weight loss or band intolerance after laparoscopic adjustable gastric banding (LAGB)...

BACKGROUND: Bariatric surgery is an effective therapy for morbid obesity but may reduce calcium absorption and significantly decrease the bone mineral density. This study examined the prevalence of secondary hyperparathyroidism (SHPT) in obese subjects during follow-up after different bariatric surgeries. We investigated predictors of SHPT. METHODS: We enrolled 1470 obese subjects undergoing bariatric/metabolic surgery with at least 1-year follow-up, including 322 patients undergoing Roux-en-Y gastric bypass (RYGB), 695 undergoing single anastomosis (mini-) gastric bypass (SAGB), 93 undergoing laparoscopic adjustable gastric banding (LAGB), and 360 undergoing sleeve gastrectomy (SG)...

INTRODUCTION: Laparoscopic adjustable gastric banding (LAGB) is acknownledged as a popular and effective surgical option in the management of obesity and related metabolic diseases. This procedure is a remarkably safe operation from both a general surgical and bariatric perspective. It facilitates brief hospitalization and can be performed by single incision. METHODS: We analyzed the most common LAGB complications as intraoperative and postoperative gastric perforation, stomach slippage/dilatation, port/tubing complications and intragastric band migration which occurred in our long decades clinical experience...

BACKGROUND: Prosthetic materials wrapped around a portion of the stomach have been used to provide gastric restriction in bariatric surgery for many years. Intraluminal erosion of adjustable and nonadjustable gastric bands typically occurs many years after placement and results in various symptoms. Endoscopic management of gastric band erosion has been described and allows for optimal patient outcomes. OBJECTIVES: We will describe our methods and experience with endoscopic management of intraluminal gastric band erosions after bariatric procedures...

BACKGROUND: Clinical trials in the field of bariatrics, and specifically laparoscopic adjustable gastric banding (LAGB), have frequently been gender imbalanced, with males representing only 20% of examinees. Long-term gender-oriented results, and specifically quality of life (QOL) parameters, have not been addressed sufficiently. The aim of our study was to examine the long-term gender association with outcome of LAGB including the impact on QOL. METHODS: A retrospective cohort study of patients who underwent LAGB between 2006 and 2014 by a single surgeon was conducted...

BACKGROUND: In many countries, laparoscopic adjustable gastric banding (LAGB) was previously the most commonly performed bariatric procedure due to its operative safety and early efficacy. This procedure is now superseded because of doubtful long-term results and late complications. Many people eventually required revisional bariatric surgery such as conversion to single anastomosis gastric bypass (SAGB). This study aims to assess the safety and durability of single-stage conversion from LAGB to SAGB in patients who are intolerant to LAGB and who also fail to lose weight, or re-gain weight...

BACKGROUND: There is vast evidence that supports the importance of obesity in the pathogenesis and progression of cardiovascular disease. Rapid weight loss induced by laparoscopic Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (LAGB) has proven beneficial. The aim of this study is to evaluate laparoscopic sleeve gastrectomy (LSG) as an alternative treatment modality and its impact on the Framingham-BMI 10-year risk score. METHODS: We retrospectively reviewed all patients that underwent bariatric surgery at our institution between 2010 and 2014...

BACKGROUND: Studies conducted in Poland have found that 1% (~300,000) of Polish adults are obese. The degree of weight loss and reduction of discomfort associated with severe obesity are used to evaluate bariatric surgery outcomes. From the patient's point of view, QoL and mental health are the most important determinants of successful surgery, which is why interest in QoL assessment has increased. OBJECTIVES: To assess the effect of BMI on quality of life and depression levels depending on the type of bariatric surgery...

In this paper, the microstructure, the room-temperature and high-temperature tensile mechanical properties of monolithic TA15 alloy and TiB whisker-reinforced TA15 titanium matrix composites (TiBw/TA15) fabricated by vacuum hot-pressing sintering were investigated. The microstructure results showed that there were no obvious differences in the microstructure between monolithic TA15 alloy and TiBw/TA15 composites, except whether or not the grain boundaries contained TiBw. After sintering, the matrix microstructure presented a typical Widmanstätten structure and the size of primary β grain was consistent with the size of spherical TA15 titanium metallic powders...

Controlling grain size in polycrystalline nickel base superalloy is vital for obtaining required mechanical properties. Typically, a uniform and fine grain size is required throughout forging process to realize the superplastic deformation. Strain amount occupied a dominant position in manipulating the dynamic recrystallization (DRX) process and regulating the grain size of the alloy during hot forging. In this article, the high-throughput double cone specimen was introduced to yield wide-range strain in a single sample...

BACKGROUND: Anemia following bariatric surgery is a known complication. To prevent nutrient deficiencies, adolescents require multivitamin/mineral supplementation following bariatric surgery. The purpose of this study was to investigate if routine multivitamin/mineral supplementation is sufficient to prevent anemia in adolescents undergoing bariatric surgery, particularly sleeve gastrectomy (SG), a procedure that may induce nutrient malabsorption. METHODS: We conducted a retrospective review of pediatric patients who underwent SG (34 patients) and laparoscopic adjustable gastric banding (LAGB) (141 patients) (January 2006 through December 2013)...

BACKGROUND: The latter are inhabited by over 15 million people, i.e. 39.5% of Polish population, including about 5 million rural residents in the Podlaskie voivodeship. The incidence of obesity is associated with increased prevalence of obesity-related conditions. The conducted studies do not confirm the efficacy of conservative treatment obesity, but show that bariatric procedures produce the best long-term results. OBJECTIVES: The aim of the study was to present the effects of bariatric obesity treatment (LAGB, SG, RYGB) on body mass index (BMI), selected diabetes control parameters, dyslipidemia, hepatic and renal enzymes, blood count, and hypertension control...
