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...

BACKGROUND: A learning curve (LC) is a graphic display of the number of consecutive procedures performed necessary to reach competence and is defined by complications and duration of surgery (DOS). There is little evidence on the LC of surgical residents in bariatric surgery. Aim of the study is to evaluate whether the laparoscopic Roux-en-Y gastric bypass (LRYGB) can be safely performed by surgical residents, to evaluate the LC of surgical residents for LRYGB and to assess whether surgical residents fit in the LC of the bariatric center which has been established by their proctors...

BACKGROUND: The effect of positive end-expiratory pressure (PEEP) has been studied in detail after induction of general anesthesia especially in obese individuals. However, sparse information can be gathered from the literature regarding its effect when applied at the time of induction and the time of onset of its effect. Thus, this study was planned to assess the effect of PEEP when applied for a single minute in morbidly obese patients. MATERIALS AND METHODS: This was a randomized prospective study comprising seven morbidly obese patients (body mass index ≥40 kg/m(2))...

BACKGROUND AND OBJECTIVES: There is a high prevalence of undiagnosed obstructive sleep apnoea (OSA) in obese surgical patients. We investigated the extent to which anthropometric measurements can be used to identify the presence of significant OSA (Apnoea/Hypopnoea Index (AHI) ≥ 20) in adult patients. MATERIALS AND METHODS: We prospectively studied 1357 adult patients scheduled for elective laparoscopic bariatric surgery. Prior to surgery, body mass index (BMI), gender, neck circumference, STOP-Bang score, SpO2, neck and trunk fat (by dual X-ray absorptiometry) were recorded...

BACKGROUND: Paraesophageal hernia (PEH) is a common condition that bariatric surgeons encounter. Expert opinion is split on whether bariatric surgery and PEH repair should be completed concurrently or sequentially. We hypothesized that concurrent bariatric surgery and PEH repair is safe. OBJECTIVES: We examined 30-day outcomes after concomitant PEH repair and bariatric surgery. SETTING: National database, United States. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database (2011-2014), we identified patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) with or without PEH repair...

BACKGROUND: Studies have shown conflicting effects of resident involvement on outcomes after laparoscopic bariatric surgery. Resident involvement may be a proxy for a teaching environment in which multiple factors affect patient outcomes. However, no study has examined outcomes of laparoscopic bariatric surgery based on hospital teaching status. OBJECTIVE: To compare outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) between teaching hospitals (THs) and nonteaching hospitals (NTHs)...

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: The efficacy of antiretroviral therapy has made HIV a chronic condition. The prevalence of obesity in HIV positive patients has subsequently risen and is present in 6-34% of men and 21-30% of women (Keithley et al. J Assoc Nurses AIDS Care 20(4):260-74, 2009). Sleeve gastrectomy is a safe and effective procedure for weight loss in the general population, but having HIV may bring hesitation to performing bariatric surgery for some practitioners. OBJECTIVES: The aim of this study is to evaluate the safety and efficacy of laparoscopic sleeve gastrectomy (LSG) in patients with HIV...
