Women with Anemia Refractory to Oral Iron Treatment Following Bariatric Surgery: a Short-Term Analysis.

Introduction: Iron deficiency and anemia are common after bariatric surgery. Women have a higher risk of developing such long-term complications. Though oral supplementation is indicated, intravenous iron therapy is required in some cases.

Complications Rate Variability after Bariatric Surgery and the Importance of Standardization of a Reporting System.

Background: The rate of early (< 30 days) complications after bariatric surgery has been reported to be 0.4-27.4%.

Weight loss before bariatric surgery and its impact on poor versus excellent outcomes at 2 years.

Purpose: To identify preoperative factors that influence the outcomes of gastric bypass surgery, in terms of excess weight loss at 24 months.

Methods: This retrospective study included two groups of patients who underwent laparoscopic gastric bypass surgery. Group A (poor outcomes) had ≤ 50%EWL or BMI ≥ 30 kg/m; group B (excellent outcomes) had ≥ 80%EWL at 24 months.

Long versus short biliopancreatic limb in Roux-en-Y gastric bypass: short-term results of a randomized clinical trial.

Background: The Roux-en-Y gastric bypass continues to be one of the most performed bariatric surgeries because of its adequate balance of outcomes, complications, and durability. Recently, the role of the biliopancreatic limb on weight loss and co-morbidity control has gained attention because it seems to have a positive impact based on limb length.

Objective: To compare results at 12 months of a "standard" (group 1) versus a long (group 2) biliopancreatic limb bypass.

Metabolic Surgery and Class 1 Obesity (< 35 kg/m): a Prospective Study with Short-, Mid-, and Long-term Results Among Latinos.

Introduction: Metabolic surgery for managing class 1 obesity and type 2 diabetes mellitus has recently gained popularity. The Latino population presents high rates of these diseases. Reports on surgical outcomes in this population are scarce.

Type 2 Diabetes Mellitus Remission Models Following Laparoscopic Gastric Bypass: a 4-Model Analysis in a Latino Population.

Background: Bariatric surgery is indicated for major weight loss and for the control of associated comorbidities, particularly type 2 diabetes. Remission prediction scores have been proposed for this end, such as: DiaRem, Ad-DiaRem, ABCD, and DiaBetter. Nevertheless, they have not been evaluated all together in a specific population.

Unexpected Intraoperative Findings, Situations, and Complications in Bariatric Surgery.

Background: Bariatric surgery is considered a safe therapy to treat obesity. Postoperative complications are well known; however, there is a lack of data describing intraoperative complications and/or unexpected findings, and if there is further impact on outcomes.

Methods: Retrospective study with patients operated between 2013 and 2016 at a single institution.

Depression Before and After Bariatric Surgery in Low-Income Patients: the Utility of the Beck Depression Inventory.

Background: The prevalence of psychological disorders in bariatric surgery candidates is well established, where anxiety and depression are commonly observed. Depression prevalence and evolution after gastric bypass, and its impact on weight loss, have been less explored, especially among low-income patients.

Methods: A retrospective study with low-income patients undergoing bariatric surgery from 2015 to 2016.

The Impact of Preoperative BMI (Obesity Class I, II, and III) on the 12-Month Evolution of Patients Undergoing Laparoscopic Gastric Bypass.

Background: Whether or not the initial body mass index (BMI) influences weight loss and comorbidities improvement after bariatric surgery continues to be a matter of debate. The main reason for this is a lack of studies including obesity class I.

Methods: Retrospective study with patients submitted to gastric bypass at a single institution.

Metabolic syndrome 2 years after laparoscopic gastric bypass.

Background: The latest diabetes consensus identified obesity as key component of the metabolic syndrome. The role of bariatric surgery over such syndrome has been less explored with a lack of long term studies, and especially among Mexicans.

Methods: Retrospective study including patients with metabolic syndrome submitted to laparoscopic gastric bypass at a single institution with complete data after 24 months.

Type 2 diabetes mellitus outcomes after laparoscopic gastric bypass in patients with BMI <35 kg/m using strict remission criteria: early outcomes of a prospective study among Mexicans.

Background: Mild obesity (BMI 30-34.9 kg/m) is highly prevalent worldwide and is associated with type 2 diabetes mellitus. The efficacy of bariatric surgery remains unclear, including among Mexicans.

A Prospective Study of the Conservative Management of Asymptomatic Preoperative and Postoperative Gallbladder Disease in Bariatric Surgery.

Introduction: Bariatric surgery is the most effective therapy for weight loss in patients with morbid obesity. One of the most common long-term complications includes cholelithiasis. There is not a clear consensus in how to treat an asymptomatic gallbladder disease before and after bariatric surgery.

Revisional Surgery Following Laparoscopic Gastric Plication.

Background: The laparoscopic gastric plication (LGP) is a relative new bariatric procedure that has gained popularity over the last few years, but no real consensus exists and the evidence is unclear, especially in its real efficacy, safety, and durability.

Methods: Retrospective study analyzing the records patients submitted to LGP between 2009 and 2010. The primary objective was to describe the characteristics and outcomes of patients submitted to revisional surgery.

Taste and Olfactory Changes Following Laparoscopic Gastric Bypass and Sleeve Gastrectomy.

Background: Alterations in taste/smell after bariatric surgery have been observed, but few data is available. Some authors documented these changes and their role on weight loss but there is no evidence after laparoscopic sleeve gastrectomy (LSG).

Methods: Cohort study with patients submitted to laparoscopic gastric bypass (LGBP) and LSG that were asked to participate in a validated survey.

Laparoscopic gastric bypass vs. sleeve gastrectomy in the super obese patient: early outcomes of an observational study.

Background: Super obesity [body mass index (BMI) > 50 kg/m2] can yield to higher morbidity/mortality in bariatric surgery, this could be related to patient's characteristics and/or surgeon's experience. In morbid obesity, both techniques proved to have a positive impact and sometimes comparable outcomes during the first 2 years. This has not been clearly analyzed in the super obese patient.
