Changes in various grain interfaces, including the grain boundary and phase boundary, are a strong indication of microstructural changes, particularly ultra-fined grains achieved by large strain deformation and subsequent annealing. After direct rolling and cross rolling with the same strain of ε = 2, the distributions of the interfaces in annealed UNS S32304 duplex stainless steel were investigated using electron backscatter diffraction (EBSD) in this study. The ferrite experienced continued recovery, and a high density of low-angle grain boundaries (LAGBs) was produced...

BACKGROUND: Bariatric surgery predisposes patients to development of cholelithiasis, and therefore the need of a subsequent cholecystectomy; however, the incidence of cholecystectomy after bariatric surgery is debated. OBJECTIVE: The purpose of our study is to assess the incidence of cholecystectomy after 3 of the most common bariatric procedures. SETTING: University Hospital, involving a large database in New York State. METHODS: The Statewide Planning and Research Cooperative System administrative longitudinal database was used to identify all patients undergoing Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and laparoscopic adjustable gastric banding (LAGB) between 2004 and 2010...

Background: Laparoscopic adjustable gastric band (LAGB) has been an established bariatric procedure for the last three decades and was, for many years, the first-choice procedure for the treatment of chronic obesity. However, more recently, the popularity of the LAGB has been in sharp decline and has been replaced by other procedures such as the Roux-En-Y gastric bypass and sleeve gastrectomy. A key driver in this decline has been the high revision and early explanation rates reported in some studies...

INTRODUCTION: Bariatric surgery reduces obesity and knee osteoarthritis (OA) pain, but some patients improve more than others. We aimed to identify characteristics that predict this knee pain improvement. METHODS: We reviewed NYU Langone Health bariatrics records (2002-2015) and called eligible patients reporting pre-operative knee pain. Patients were asked to rate their pain on a 10-point scale at three time points: before surgery, one year post-surgery, and time of survey administration...

INTRODUCTION: Bariatric surgery is considered the most effective treatment for obesity. A recent worldwide survey demonstrated that Laparoscopic Sleeve Gastrectomy (LSG) is the most commonly performed bariatric procedure, while Laparoscopic Adjustable Gastric Banding (LAGB) has been almost abandoned. OBJECTIVES: The aim of this retrospective study was to compare 5-year results of LSG and LAGB at our Institution. MATERIALS AND METHODS: Prospective maintained database of our Institution was reviewed to find all patients who had undergone LSG between January 2009 and December 2011...

BACKGROUND: Laparoscopic gastric band (LAGB) has gained popularity among the surgical community since its first description in the early 90'. Actually, it is the third most practiced bariatric procedure in the world. The mean advantage of LAGB is a low rate of early postoperative morbidity. These satisfactory early results are in complete opposition with relatively high long term morbidity and a high rate of weight loss failure. AIM: Long term morbidity, weight loss and life quality index after LAGB were analyzed...

BACKGROUND AND OBJECTIVES: Bariatric surgery improves metabolic diseases and alters the intestinal microbiota in animals and humans, but different procedures reportedly have different impacts on the intestinal microbiota. We developed laparoscopic sleeve gastrectomy with duodenojejunal bypass (LSG-DJB) as an alternative to laparoscopic Roux-en-Y gastric bypass (LRYGB) in addition to laparoscopic sleeve gastrectomy (LSG) for Japanese patients with obesity. We investigated the precise change in the intestinal microbiota induced by these procedures in the present study...

The long-term outcomes of weight loss maintenance induced by laparoscopic adjustable gastric band (LAGB) followed by multidisciplinary medical care in patients with type 2 diabetes mellitus (T2DM) (beyond 3 years) are scarcely reported. Study aims were to determine the longer term metabolic outcomes following LAGB combined with medical care in patients with T2DM. This is a longitudinal analysis of 200 adults with T2DM who had LAGB between 2003 and 2008 and were followed up till 2013 at a single bariatric unit in a tertiary UK centre...

Sang-Yong Son, Yun Chan Park
BACKGROUND: Band slippage is known to be a troublesome complication of laparoscopic adjustable gastric banding (LAGB), often requiring surgical intervention. To prevent band slippage, a new auxiliary device "S-loop" was developed. METHODS: From July 2010 to January 2014, a total of 814 LAGBs were performed by a single surgeon. The patients were divided into two groups based on the application of S-loop: conventional LAGB group (n = 378) and S-loop group (n = 436)...

BACKGROUND: Bariatric surgery is the most effective treatment for severe obesity, capable of producing more than 50% excess weight loss at 10-year follow-up (James Clin Dermatol 1; 22:276-80; O'Brien Br J Surg 2; 102:611-17; Buchwald et al. Metab Syndr 3; 347-56). The success of bariatric surgery extends far beyond weight loss, with up to 80-90% of patients having improvement or resolution of many of their weight-related co-morbidities including type II diabetes mellitus and hypertension (Puzziferri et al...

We describe a case of polymicrobial bacterial pericarditis with Klebsiella pneumoniae and Proteus mirabilis , caused by pericardial penetration of the tip of the catheter of a laparoscopic adjustable gastric band (LAGB). The patient developed a cardiac tamponade, and subsequently emergency pericardiocentesis was performed. Analysis of earlier CT scans showed that the tip of the catheter had migrated through the liver and through the diaphragm into the pericardium, and was in contact with the myocardium. After stabilisation he was operated to remove the LAGB...

Weight loss after bariatric surgery is associated with reduction in adverse cardiovascular outcomes; however, the impact of obstructive sleep apnea (OSA) on reduction of cardiovascular outcomes after bariatric surgery in morbidly obese patients is not known. We retrospectively assessed differences in cardiovascular events after laparoscopic adjustable gastric banding (LAGB)-induced weight loss in patients with and without OSA before and after propensity score matching for age, sex, body mass index (BMI), and major comorbidities between the two groups and determined predictors of poor outcomes...

BACKGROUND: In the USA, three types of bariatric surgeries are widely performed, including laparoscopic sleeve gastrectomy (LSG), laparoscopic Roux-en-Y gastric bypass (LRYGB), and laparoscopic adjustable gastric banding (LAGB). However, few economic evaluations of bariatric surgery are published. There is also scarcity of studies focusing on the LSG alone. Therefore, this study is evaluating the cost-effectiveness of bariatric surgery using LRYGB, LAGB, and LSG as treatment for morbid obesity...

BACKGROUND: As the number of obese patients in the United States continues to grow, there is a parallel increase in the number of bariatric surgery patients. A quarter of these patients will return to the Emergency Department (ED) within the first two years of the index procedure. OBJECTIVE: An understanding of the most common bariatric procedures and their related complications will greatly aide the Emergency Medicine physician in the care of these patients. DISCUSSION: Abdominal pain is the most common reason for bariatric patients to present to the ED and can represent a diagnostic challenge to EM physicians...

AIM: Laparoscopic adjustable gastric banding (LAGB) migration is an uncommon late complication after bariatric surgery. It usually presents with an unexplained weight increase or without any symptom. Current guidelines do not establish the timing of a clear endoscopic follow-up to prevent and/or to treat this kind of complication. PATIENTS AND METHODS: Long-term follow-up was performed in 217 patients with LAGB (37 underwent surgery in other bariatric centers). At the endoscopic check, 3 patients presented banding erosion respectively 7, 9 and 11 years after surgery...

BACKGROUND: A lack of clarity remains over the optimal strategy for the management of laparoscopic adjustable gastric band (LAGB) slippage, which, although rare (around 3% in our experience), can when acute result in obstruction, gastric erosion or ischaemia. Typically, slipped bands are removed acutely. The aim of this study was to explore outcomes following immediate or delayed resiting of slipped LAGBs in a single centre, comparing simple repositioning with retunnelling and replacement...
