Purpose: The effectiveness of biliopancreatic diversion with duodenal switch (BPD/DS) for weight loss is well established, yet there remains ongoing debate over optimal limb lengths to maximize weight loss without compromising safety. We aimed to evaluate the impact of BPD/DS limb lengths on weight loss outcomes and comorbidity resolution.
Material And Methods: A multicenter review of patients who underwent primary BPD/DS between 2008 and 2022.
Biliopancreatic diversion with duodenal switch (BPD-DS) and single anastomosis duodeno-ileostomy with sleeve (SADI-S) are associated with superior and sustained weight loss outcomes. Despite their growing popularity, long-term safety profiles, particularly the risk of internal hernia (IH), remain underexplored. This study aimed to evaluate the incidence and characteristics of IH following BPD-DS and SADI-S procedures, comparing their clinical presentation, diagnostic methods, and outcomes.

Purpose: Postoperative nausea and vomiting (PONV) is one of the most common adverse effects of anesthesia and surgery, resulting in patient discomfort and dissatisfaction. Latest research has demonstrated the efficacy of NK-1 receptor antagonists in PONV management and its use in chemotherapy nausea prophylaxis. The authors of this article would like to provide evidence to support the use fosaprepitant, as monotherapy, in postoperative care, replacing a polypharmacological standard of care regimen.

Settings: Postoperative pain management is an ever-growing challenge with the rise of the opioid crisis. Ketamine is an NMDA channel blocker, considered an alternative to perioperative opioid use; small concentrations are safe. Objective: The primary objective of this study was to evaluate the impact of perioperative ketamine administration on postoperative opioid use and the length of hospital stay in bariatric patients.
View Article and Find Full Text PDFPurpose: Metabolic and bariatric surgery (MBS) could improve health-related quality of life (HrQoL) for selected patients with obesity. Although biliopancreatic diversion with duodenal switch (BPD-DS) is regarded as the most effective MBS technique in achieving weight loss, no consensus has been reached on the impact of BPD-DS on HrQoL. The aim of this meta-analysis is to assess the mid-term HrQoL after BPD-DS in the management of patients with obesity.
View Article and Find Full Text PDFBackground: Sleeve gastrectomy (SG) in current literature showed an increased risk of "de novo" gastroesophageal reflux disease (GERD) and increased risk for Barrett's esophagus in longer follow-up series, with a possibility of esophageal adenocarcinoma in this population. Adding primarily an anterior Dor Fundoplication to SG (Sleeve-Dor) may protect the patient for future and can potentially avoid these chronic complications for patients with obesity.
Methodology: A standard SG is performed laparoscopically, and a small redundance of the fundus is maintained as a wrap, and this will be fixed to the right crura without dissection of the anatomy of the hiatus.
Purpose: Describe and analyze the safety and weight loss performance of biliopancreatic diversion and duodenal switch (BPD-DS) and single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S), verifying any possible superiority according to preoperative BMI.
Methods: Retrospective review of patients who underwent primary SADI-S or BPD-DS in three bariatric centers. Study groups were further stratified according to preoperative BMI (subgroup 1: BMI < 50; subgroup 2: 50 ≤ BMI < 55; subgroup 3: BMI ≥ 55).
Introduction: Several modalities have been proposed to tackle insufficient weight loss and weight regain after bariatric surgery; we aimed to evaluate efficacy and safety of duodenal switch conversion as a salvage procedure.
Material And Methods: Data from patients who underwent duodenal switch conversions (n = 50) were retrospectively studied. Excess weight loss % and total body weight loss % were compared between primary procedure and duodenal switch conversion.
Background: Endoscopic sleeve gastroplasty (ESG) is an endolumenal, organ-sparing therapy for obesity, with wide global adoption. We aimed to explore the efficacy and safety of ESG with lifestyle modifications compared with lifestyle modifications alone.
Methods: We conducted a randomised clinical trial at nine US centres, enrolling individuals aged 21-65 years with class 1 or class 2 obesity and who agreed to comply with lifelong dietary restrictions.
Continuous nonlinear transmission lines (NLTLs), also known as gyromagnetic lines, consist of ferrite-based magnetic cores biased by an external magnetic field. Over the past years, many analytical and experimental studies have predicted the rise time reduction of the input pulse to the range of a few nanoseconds or even hundreds of ps experimentally observed in such gyromagnetic lines. This effect, known as pulse sharpening, is investigated in this paper built on a model based on a periodic structure of inductive-capacitive cells in series with magnetization-driven voltage sources expressed by the one-dimensional form (1D) of the Landau-Lifshitz-Gilbert (LLG) gyromagnetic equation.

However, a small number of RYGB patients can still develop severe reflux symptoms that require a surgical intervention.
Aim: To examine and describe the patient population that requires an anti-reflux procedure after RYGB evaluating demographics, characteristics, symptoms and diagnosis.
Background: The benefits of oversewing the staple lines during laparoscopic sleeve gastrectomy have been controversial. No study examined the benefit of oversewing the staple lines in robotic sleeve gastrectomy (RSG). This retrospective study aims to examine the difference in immediate postoperative complications, readmissions, reoperations, and emergency room visits between RSG patients with and without oversewn staple lines at a single, large-volume, bariatric center.

Background: One of the most significant concerns after laparoscopic sleeve gastrectomy (LSG) is the new-onset or worsening of gastroesophageal reflux disease (GERD). Some patients with LSG undergo a conversion to Roux-en-Y gastric bypass (RYGB) because of severe GERD. Cardiopexy at the time of LSG may help prevent GERD.

Background: Conversions and revisions after bariatric procedures are inevitable and associated with longer operative time and higher complication rates. Because robot-assisted procedures allow better dissection, robotic conversions and revisions may be more beneficial to the patients than laparoscopic ones.
Objectives: This study aimed to compare the feasibility and safety of robot-assisted conversions and revisions to laparoscopic procedures.
Objectives: To compare the short-term safety and effectiveness of long biliopancreatic limb Roux-en-Y gastric bypass (RYGB) to that of regular RYGB.
Setting: Academic hospital, United States.
Methods: A retrospective chart review was performed on 89 consecutive patients who underwent RYGB between February 4, 2014 and March 12, 2015.
Background: Duodenal switch is a choice of conversion when patients fail to lose or regain weight after Roux-en-Y gastric bypass (RYGB). This study aims to evaluate the effectiveness and safety of duodenal switch as a secondary operation for patients who presented with insufficient weight loss or weight regain after a RYGB.
Methods: A retrospective chart review was performed on 15 patients who underwent a conversion of RYGB to single anastomosis duodeno-ileal bypass with sleeve (SADI-S) or biliopancreatic diversion with duodenal switch (BPD-DS) due to weight regain between December 31, 2013 and October 31, 2018.
Background: Endoscopic sleeve gastroplasty (ESG) is an option for patients with Class I and II obesity or patients who refuse to undergo a laparoscopic bariatric surgery. The aims of this study are as follows: (1) to demonstrate a short-term outcome after primary ESG and (2) to compare the effectiveness of weight loss between Class I and Class II obesity patients.
Methods: Patients undergoing ESG at four bariatric centers in Brazil between April 1, 2017 and December 31, 2018 were prospectively enrolled in the study (BMI 30.
