Background: Sleeve gastrectomy(SG) is a popular bariatric surgery procedure with rare but dreaded complications. Although drain amylase levels are a reliable early predictor of anastomosis leakage in oesophagectomy and pancreaticoduodenectomy, for SG have not yet been studied. We aimed to monitor drain amylase levels to ascertain their applicability for early diagnosis of gastric leakage in SG. Read More

Introduction: The combination of Cushing's syndrome and obesity, one of the most common manifestations of the syndrome itself, may be associated with the worsening of post-operative outcomes in case of laparoscopic adrenalectomy. This study focused on the laparoscopic treatment of Cushing's syndrome with the purpose to identify any relevant difference between morbidly obese, mildly obese and non-obese patients.

Material And Methods: Patients were retrospectively divided into three groups according to their Body Mass Index (BMI). Read More

Sleeve Gastrectomy (SG), as the most effective bariatric surgery, has been using to chronically lose weight and control glucose metabolism in Type 2 diabetes mellitus patients. However, the underlining mechanism is still unclear. In this study, we performed SG on Zucker diabetes fatty (ZDF) rat and investigated visceral lipid metabolism and energy metabolism. Read More

IL-1β stimulates expression of prostaglandin (PG)-synthesizing enzymes cyclooxygenase (COX)-2 and aldo-keto reductase (AKR)1B1 in human preadipocytes. We aimed to examine the impact of IL-1β, COX-2 and AKR1B1 on markers of human visceral and subcutaneous adipose tissue function, and to assess whether PG synthesis by these enzymes mediates IL-1β effects. Omental and subcutaneous fat samples were obtained from bariatric surgery patients. Read More

Bariatric surgery is an effective strategy for blood pressure (BP) reduction, but most of the evidence relies on office BP measurements. In this study, we evaluated the impact of bariatric surgery on 24-hour BP profile, BP variability, and resistant hypertension prevalence. This is a randomized trial including obese patients with grade 1 and 2 using at least 2 antihypertensive drugs at maximal doses or >2 at moderate doses. Read More

Introduction: Postoperative pain remains the most common challenge following inpatient and outpatient surgeries, and, therefore, opioid analgesics are widely used during the perioperative period. The aim of this study is to examine the efficiency of transversus abdominis plane (TAP) block using liposomal bupivacaine in reducing the use of opioid analgesics during the perioperative period of bariatric procedures.

Material And Methods: A retrospective chart review was performed on 191 patients who underwent a laparoscopic bariatric procedure between September 13, 2017, and February 26, 2018. Read More

Altered GLP-1 secretion from L cells has been implicated in the development of type 2 diabetes mellitus and its resolution following bariatric surgery. However, changes in L cell gene expression, which may form the basis for altered functionality after high fat diet (HFD) or bariatric surgery, have either not been investigated or have given conflicting results. We developed a gcg-DTR-eGFP reporter mouse to isolate ileal and colonic L cells from HFD fed insulin resistant mice and mice showing improved glucose tolerance following vertical sleeve gastrectomy (VSG).

Up to 80% of patients who undergo bariatric surgery are women of childbearing age. Coupled with improved fertility in women with obesity after bariatric surgery, pregnancy postbariatric surgery has become increasingly more common. Although numerous studies have evaluated associations of bariatric surgery with pregnancy outcomes, the effect of maternal nutritional status on maternal and perinatal outcomes is not well established.

Background And Aims: Placement of the duodenal-jejunal bypass liner (DJBL) leads to rapid weight loss and restoration of insulin sensitivity in a similar fashion to bariatric surgery. Increased systemic bile acid levels are candidate effectors for these effects through postprandial activation of their receptors TGR5 and FXR. We aimed to quantify postprandial bile acid, GLP-1 and FGF19 responses and assess their temporal relation to the weight loss and metabolic and hormonal changes seen after DJBL placement. Read More

Context: Bariatric surgery results in reduced muscle mass as weight is lost, but postoperative changes in muscle strength and performance are incompletely understood.

Objective: To examine changes in body composition, strength, physical activity, and physical performance 12 months following Roux-en-Y gastric bypass (RYGB).

Design, Participants, Outcomes: In a prospective cohort of 47 obese adults (37 women, 10 men) aged 45 ± 12 years (mean ±SD) and BMI 44 ± 8 kg/m2, we measured body composition by DXA, handgrip strength, physical activity and physical performance (chair stand time, gait speed, 400-meter walk time) before and 6 and 12 months after RYGB.

Bariatric surgery is recommended when other weight loss interventions, such as lifestyle modification or medications, have failed. A considerable number of women undergoing bariatric surgery are of childbearing age; hence, it is necessary to be aware of the effects of bariatric surgery on pregnancy for managing these patients. Although bariatric surgery is associated with positive effects on cardiovascular and metabolic parameters, side effects such as anaemia, the risk of developing internal hernia, altered glucose metabolism and the risk of small for gestational age offspring have to be considered.

Importance: Schizophrenia is associated with a reduced life expectancy of 15 to 20 years owing to a high prevalence of cardiometabolic disorders. Obesity, a key risk factor for the development of cardiometabolic alterations, is more prevalent in individuals with schizophrenia. Although obesity is linked to the altered reward processing of food cues, no studies have investigated this link in schizophrenia without the confounds of antipsychotics and illness chronicity.

Purpose: Anastomotic leakages or staple line defects after Roux-en-Y gastric bypass (RYGB) and primary laparoscopic sleeve gastrectomy (LSG), respectively, with consecutive bariatric revisional surgery are associated with relevant morbidity and mortality rates. Endoscopic vacuum therapy (EVT) with or without stent-over-sponge (SOS) has been shown to be a promising therapy in foregut wall defects of various etiologies and may therefore be applied in the treatment of postbariatric leaks.

Methods: We report the results of six consecutive patients treated with EVT (83% in combination with SOS) for early postoperative leakages in close proximity to the esophagogastric junction (EGJ) after LSG (n = 2) and RYGB (n = 4) from May 2016 to May2018. Read More

Background: Sleeve gastrectomy (SG) is currently the most commonly performed bariatric procedure in the United States; however, it can be associated with development of de novo gastroesophageal reflux (GERD) or worsening of existing GERD.
