Introduction
My longstanding goal has been to apply new laparoscopic techniques to obesity and metabolic surgery with a particular research interest in its metabolic and nutritional consequences. I believe that multidisciplinary teamwork is essential to advance the validation of new surgical techniques.Nowadays, I am a young gastrointestinal surgeon working in the Obesity Surgery Department of Bellvitge University Hospital in Barcelona, Spain with Dr. Jordi Pujol Gebelli as a mentor.

Article
Introduction Duodenal switch (DS) is considered one of the most effective techniques to achieve weight loss and reduce comorbidities in patients with morbidly obesity. Material and methods Descriptive single-center study. 224 patients were analyzed who underwent direct laparoscopic DS in our center. The objective was to describe the results of wei...
Article
Introduction: The "Single Anastomosis Duodeno-Ileal bypass with Sleeve gastrectomy" (SADI-S) is a bariatric surgery conceived to simplify the duodenal switch in order to reduce its postoperative complications. The objective of this study is to assess the safety and efficacy of SADI-S, comparing its results in both direct and two-step procedure. M...

Purpose Long-term studies comparing the mechanisms of different bariatric techniques for T2DM remission are scarce. We aimed to compare type 2 diabetes (T2DM) remission after a gastric bypass with a 200-cm biliopancreatic limb (mRYGB), sleeve gastrectomy (SG), and greater curvature plication (GCP), and to assess if the initial secretion of gastroin...

Objective: To explore the meal response of circulating succinate in patients with obesity and type 2 diabetes undergoing bariatric surgery and to examine the role of gastrointestinal glucose sensing in succinate dynamics in healthy subjects. Research design and methods: Cohort I comprised 45 patients with morbid obesity and type 2 diabetes (BMI...

Aims/hypothesis: Midlife obesity is a risk factor for dementia. We investigated the impact of obesity on brain structure, metabolism, and cerebrospinal fluid (CSF) core Alzheimer's disease (AD) biomarkers in healthy elderly. Methods: We selected controls from ADNI2 with CSF AD biomarkers and/or fluorodeoxyglucose positron emission tomography (FD...

There is scant evidence of the long-term effects of bariatric surgery on bone mineral density (BMD). We compared BMD changes in patients with severe obesity and type 2 diabetes (T2D) 5 years after randomization to metabolic gastric bypass (mRYGB), sleeve gastrectomy (SG) and greater curvature plication (GCP). We studied the influence of first year...

Background: Mid-life obesity is related to increased risk for overall dementia and Alzheimer´s disease (AD) dementia. In the present work, we aimed to investigate the impact of obesity on brain structure, metabolism, and cerebrospinal fluid (CSF) biomarkers of amyloid (Aβ 1-42) and tau-pathology (total-tau and p-tau) in healthy elderly. Methods: We...

Background To compare changes in bone mineral density (BMD) in patients with morbid obesity and type 2 diabetes (T2D) a year after being randomized to metabolic gastric bypass (mRYGB), sleeve gastrectomy (SG), and greater curvature plication (GCP). We also analyzed the association of gastrointestinal hormones with skeletal metabolism. Methods Fort...

Background The surgical management of weight regain following RYGB remains controversial. Simpler modifications such as endoscopic suturing and banding the bypass have had variable efficacy. Distalization of the bypass has resulted in a high risk of malabsorption-related complications as reported by Amor et al. (Obes Surg. 27(1):273-274, 2017); Bor...

We aimed to explore the relationship between GLP-1 receptor (GLP-1R) expression in adipose tissue (AT) and incretin secretion, glucose homeostasis and weight loss, in patients with morbid obesity and type 2 diabetes undergoing bariatric surgery. RNA was extracted from subcutaneous (SAT) and visceral (VAT) AT biopsies from 40 patients randomized to...

Mid-life obesity is an established risk factor for Alzheimer´s disease (AD) dementia, whereas late-life obesity has been proposed as a protective state. Weight loss, which predates cognitive decline, might explain this obesity paradox on AD risk. We aimed to assess the impact of late life obesity on brain structure taking into account weight loss a...

Endobarrier® is a minimally invasive, reversible endoscopic treatment for obesity. It provokes malabsorption along 60 cm of the small intestine, which can contribute to the development of vitamin deficiencies and to changes in bone mineral density (BMD). To determine the prevalence of nutrient deficiencies, changes in body composition and BMD durin...

Introduction: The effects of bariatric surgery on skeletal health raise many concerns. Trabecular bone score (TBS) is obtained through the analysis of lumbar spine dual X-ray absorptiometry (DXA) images and allows an indirect assessment of skeletal microarchitecture (MA). The aim of our study was to evaluate the changes in bone mineral density (BM...

Weight loss has been proposed as a sign of pre-clinical Alzheimer Disease (AD). To test this hypothesis, we have evaluated the association between longitudinal changes in weight trajectories, cognitive performance, AD biomarker profiles and brain structure in 363 healthy controls from the Alzheimer´s Disease Neuroimaging Initiative (mean follow-up...

Background: Our aim was to determine the predictive value of gut hormone changes for the improvement of type 2 diabetes (T2D) following metabolic Roux-en-Y gastric bypass (mRYGB), sleeve gastrectomy (SG), and greater curvature plication (GCP) in a randomized controlled trial. Contradictory results have been obtained regarding the role of gastroint...

Background: The purpose of this study was to evaluate the efficacy and safety of Endobarrier® in grade 1 obese T2DM patients with poor metabolic control and the role of gastro-intestinal hormone changes on the metabolic outcomes. Methods: Twenty-one patients aged 54.1 ± 9.5 years, diabetes duration 14.8 ± 8.5 years, BMI 33.4 ± 1.9 kg/m(2), and H...
Article
This work aimed to explore the link between ANGPTL8 and weight loss after metabolic surgery. In the cross-sectional study (n=100), circulating ANGPTL8 concentrations were significantly lower in morbidly obese than in lean subjects, and strikingly lower in morbidly obese patients with type 2 diabetes mellitus (T2DM). Conversely, ANGPTL8 expression i...

Introduction: 39% of morbidly obese patients have type 2 diabetes mellitus (T2DM) and 80% of them can achieve diabetes remission after bariatric surgery. However, there are few randomized studies comparing the metabolic results of different surgical techniques and the hormonal mechanisms involved. Objective: To study and compare the improvement of...
