Nutritional Deficiencies Before and After Metabolic and Bariatric Surgery in Patients Above 50.0 kg/m: A Single Center Study.

Purpose: Metabolic and bariatric surgery (MBS) is an effective treatment for patients with body mass index (BMI) above 50.0 kg/m but nutritional deficiencies (ND) may arise. This study aimed to assess if patients with BMI above 50.

Diabetes Remission After Bariatric Surgery: A 10-Year Follow-Up Study.

Introduction: Treatment of type 2 diabetes (T2DM) in patients with obesity can be challenging. Metabolic and bariatric surgery (MBS) has shown promising results in improving glycemic control and even achieving remission in T2DM patients with obesity. However, the durability of glycemic improvements in T2DM patients following MBS remains insufficiently studied.

Portomesenteric Venous Thrombosis after Bariatric Surgery: A Case Series and Systematic Review Comparing LSG and LRYGB.

(1) Background: Portomesenteric Venous Thrombosis (PMVT) is a rare but serious complication of Metabolic Bariatric Surgery (MBS). Although more frequently reported after laparoscopic sleeve gastrectomy (LSG), the risk factors for PMVT remain unclear. This study aims to compare the incidence and determinants of PMVT between LSG and laparoscopic Roux-en-Y gastric bypass (LRYGB).

Intragastric Balloon as a First Step Before Metabolic Bariatric Surgery in Patients with BMI ≥ 50 kg/m: are the Results After Balloon Related to Global Outcomes After Surgery?

Introduction: Patients with body mass index (BMI) ≥ 50 kg/m, classified with obesity class IV/V, require complex treatments. Intragastric balloon (IGB) is a possible treatment before metabolic bariatric surgery (MBS) that may reduce peri-operative complications. This study evaluates IGB outcomes and complications before MBS in patients with Obesity IV/V, and subsequent MBS results, regarding weight loss and comorbidity resolution.

Efficiency and safety of single anastomosis sleeve ileal (SASI) bypass in the treatment of obesity and associated comorbidities: a systematic review and meta-analysis.

Introduction: The Single Anastomosis Sleeve Ileal (SASI) bypass is a new bariatric surgery corresponding to an adaptation of the Santoro approach, consisting of a sleeve gastrectomy (SG) followed by loop gastroileostomy. Therefore, we aimed to systematically assess all the current literature on SASI bypass in terms of safety, weight loss, improvement in associated comorbidities, and complications.

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta- Analyses (PRISMA) recommendations, we conducted a systematic review and meta-analysis by searching three databases (PubMed, Scopus, and Web of Science).

Assessing Nutritional Deficiencies in Bariatric Surgery Patients: A Comparative Study of Roux-en-Y Gastric Bypass versus Sleeve Gastrectomy.

Obesity is a worldwide epidemic, and bariatric surgery is considered the primary treatment for long-term weight loss and managing obesity-related health issues. Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most performed procedures. Nutritional deficiencies are a significant concern following bariatric surgery and can have serious consequences.

The Impact of Cholecystectomy in Patients with Post-Bariatric Surgery Hypoglycemia.

Background: Metabolic surgery is the foremost treatment for obesity and its associated medical conditions. Nonetheless, post-bariatric hypoglycemia (PBH) emerges as a prevalent complication. PBH pathophysiology implicates heightened insulin and glucagon-like peptide 1 (GLP-1) levels, with bile acids (BA) contributing to GLP-1 release.

Preoperative risk factors for early postoperative bleeding after Roux-en-Y gastric bypass surgery: a systematic review and meta-analysis.

Purpose: Although bariatric surgery is an effective intervention for obesity, it comes with risks such as early postoperative bleeding (EPB). Identifying preoperative risk factors for this complication can help patients' risk stratification and optimization. We performed a systematic review and meta-analysis to find predictors for early postoperative bleeding after Roux-en-Y gastric bypass (RYGB).

Prediabetes remission after bariatric surgery: a 4-years follow-up study.

Background: Bariatric surgery leads to weight loss and to cardiometabolic risk improvement. Although prediabetes remission after bariatric surgery is biologically plausible, data on this topic is scarce. We aimed to assess prediabetes remission rate and clinical predictors of remission in a 4 year follow up period.

Roux-en-Y gastric bypass and sleeve gastrectomy as revisional bariatric procedures after adjustable gastric banding: a retrospective cohort study.

Introduction: The frequency of revisional bariatric surgery is increasing, but its effectiveness and safety are not yet fully established. The aim of our study was to compare short-term outcomes of primary (pRYGB and pSG) and revisional bariatric surgeries (rRYGB and rSG).

Methods: We performed a retrospective cohort study assessing all patients submitted to primary and revisional (after a failed AGB) RYGB and SG in 2019.

Incidence of symptomatic gallstones after bariatric surgery: the impact of expectant management.

Background: Bariatric surgery is the most effective treatment for sustained weight reduction and obesity-related comorbidities. The development of gallstones as a result of rapid weight loss is a well-known consequence of bariatric procedures. It remains unclear, if there is an increased risk of these gallstones becoming symptomatic.

Risk and Prophylactic Management of Gallstone Disease in Bariatric Surgery: a Systematic Review and A Bayesian meta-analysis.

Background: The frequency and management of gallstone disease (GD) in bariatric patients, including the role of routine prophylactic concomitant cholecystectomy (CCY), are still a matter of debate. This study aims to assess the risk of de novo GD in patients undergoing bariatric surgery (BS) and their predictive factors, as well as mortality and morbidity in prophylactic CCY compared to BS alone.

Methods: We performed a systematic review, searching PubMed, EMBASE, and Web of Science until April 2021.

Health-related quality of life 6 years after bariatric surgery: factors influencing outcome.

Unlabelled: Bariatric surgery is the only proven treatment to significantly improve obesity and its associated comorbidities. The success of bariatric surgery goes beyond weight lost: quality of life (QoL) is acquiring relevance when evaluating outcomes after bariatric surgery but few studies evaluated factors influencing QoL at long term. The main objective of this study is to identify factors that could affect QoL more than 5 years after bariatric surgery.

Early Postoperative Bleeding After Laparoscopic Roux-En-Y Gastric Bypass: a Single Center Analysis.

Purpose: Early postoperative bleeding is a common complication after laparoscopic Roux-en-Y gastric bypass (LRYGB) and is associated with significant morbidity. We aimed to identify predictors of early postoperative bleeding after LRYGB and characterize hemorrhagic events and 30-day postoperative outcomes.

Material And Methods: We conducted a retrospective cohort study regarding all patients submitted to LRYGB in 2019 at a high-volume obesity center.

New Endoscopic Solutions in Managing Phlegmonous Esophagitis.

A 48-year-old woman was admitted in the emergency department due to epigastric pain, nausea, vomiting, and cough. She presented with fever and increased inflammatory parameters. A thoracoabdominal computed tomography (CT) was performed and revealed thickening of the gastric fundus and esophagus, with an apparent laceration in esophageal mucosa and associated dissection of esophageal wall.

Vitamin B Complex Deficiency After Roux-en-Y Gastric Bypass and Sleeve Gastrectomy-a Systematic Review and Meta-Analysis.

Bariatric surgery, although an effective method, still has complications, like nutritional deficiencies. Our aim was to summarize the evidence on the frequency of complex B vitamin deficiencies in studies comparing Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). We included 25 studies for qualitative synthesis and 21 studies for quantitative synthesis.

Roux-en-Y Gastric Bypass Vs Sleeve Gastrectomy in Super Obesity: a Systematic Review and Meta-Analysis.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are safe procedures that may present sub-optimal results in superobesity (SO). A meta-analysis was performed aiming to summarize the available evidence on weight loss (primary outcome) and comorbidities resolution of LRYGB and LSG in patients with SO (BMI ≥ 50 kg/m). From the 16 included studies, 7 integrated the meta-analysis.

Comparative Effectiveness of Bariatric Surgeries in Patients with Type 2 Diabetes Mellitus and BMI ≥ 25 kg/m: a Systematic Review and Network Meta-Analysis.

Purpose: In patients with type 2 diabetes mellitus (T2DM), bariatric surgery appears to be more effective than medical treatment (MT) at improving glycaemic control and decreasing cardiovascular risk. However, long-term effectiveness has not been systematically assessed using randomised controlled trials. In this study, we aimed to systematically assess randomised controlled trials, with at least 5 years of follow-up, on bariatric surgery in patients with T2DM and BMI ≥ 25 kg/m, as well as to compare different bariatric procedures.

Surgery for Perforated Peptic Ulcer: Is Laparoscopy a New Paradigm?

Introduction: Laparoscopic repair of perforated peptic ulcer (PPU) remains controversial mainly due to its safety and applicability in critically ill patients. The aim of this study is to compare the outcomes of laparoscopy versus laparotomy in the treatment of PPU.

Methods: Single-institutional, retrospective study of all patients submitted to surgical repair of PPU between 2012 and 2019.

How Far Can Our Expectations Go on Revisional Bariatric Surgery After Failed Adjustable Gastric Banding?

Purpose: Bariatric surgery has proven its effectiveness in the treatment of obesity and related comorbidities. However, several procedures may be required to treat this chronic disease and/or complications after bariatric surgery. The most frequent revisional surgeries performed after failed laparoscopic adjustable gastric banding (AGB) have been Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG).

Acute improvement in insulin resistance after laparoscopic Roux-en-Y gastric bypass: is 3 days enough to correct insulin metabolism?

Background: Although medium- to long-term improvement in insulin resistance and T2DM after Roux-en-Y gastric bypass (RYGB) is well documented, few studies have analyzed the acute effects after surgery. Understanding these effects might help explain the physiologic adjustments after surgery and help in managing insulin resistance and controlling the hypoglycemic treatment for bariatric patients.

Methods: We recruited a prospective cohort of 55 consecutive female patients that underwent primary laparoscopic RYGB between January and June/2011.
