Background and study aims Endoscopic ultrasound-directed transgastric intervention (EDGI) is a technique that creates an anastomosis between the gastric pouch or jejunum to the excluded stomach in Roux-en-Y gastric bypass (RYGB) anatomy to allow access to the pancreaticobiliary system. Thus far, management of anastomosis closure at the time of lumen-apposing metal stent (LAMS) removal has varied widely. This study aimed to assess the efficacy of primary closure at the time of LAMS removal using a through-the-scope (TTS) tack-based suture system...

PURPOSE: Sleeve Gastrectomy (SG) is the most performed bariatric surgery, but a considerable number of patients may require revisional procedures for suboptimal clinical response/recurrence of weight (SCR/RoW). Conversion options include One-Anastomosis Gastric Bypass (OAGB) and Single Anastomosis Duodeno-Ileal Bypass (SADI). The study aims to compare SADI vs. OAGB as revisional procedures in terms of early and mid-term complications, operative time, postoperative hospital stay and clinical outcomes...

Metabolic and bariatric surgery (MBS) is the most effective therapeutic intervention for patients with obesity, with sleeve gastrectomy (SG) being the most commonly performed primary MBS procedure. Long-term studies have demonstrated that 15-20% of patients require revisional bariatric surgery (RBS) due to weight-related issues or surgical complications. Despite the gold standard being laparoscopic revision, there are other available approaches such as open or robotic-assisted. An extensive literature review was performed for articles from their inception to February 2024...

BACKGROUND: One anastomosis gastric bypass (OAGB) prevalence is increasing worldwide and shows good mid- to long-term results. Data on long-term outcomes of revisional OAGB (rOAGB) is limited. This study objective is to evaluate the long-term outcomes of patients undergoing primary OAGB (pOAGB) and rOAGB. METHODS: A retrospective analysis of a prospectively maintained patient registry at a single-tertiary center. Patients undergoing OAGB from January 2015 to May 2016 were included and grouped to pOAGB and rOAGB...

BACKGROUND: The prevalence of patients suffering from extreme obesity (body mass index (BMI) ≥ 50) has significantly increased over the past three decades, surpassing the rise in the general population of overweight patients. Weight loss outcomes after bariatric surgery in patients suffering from extreme obesity are less favorable, with a higher incidence of weight regain. Variations of existing bariatric procedures have been proposed to address this issue. One such variation is adding a gastric band to limit the expansion of the newly created pouch...

Background: Bariatric surgery delivers substantial weight loss for obese patients with comorbidities like diabetes mellitus. We aimed to investigate the impacts of bariatric surgery on diabetic markers after 5 years of follow-up. Methods: This is a retrospective study on patients with diabetes and a history of bariatric surgery between 2016-2017. The diabetic markers before and 5 years following surgery, including a lipid profile, glucose level, and the required antidiabetic medications, were evaluated. Results: 34 consecutive patients were included, 30 (88...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) has consistently demonstrated excellent weight loss and comorbidity resolution. However, outcomes vary based on patient's BMI. Single anastomosis duodeno-ileostomy with sleeve (SADI-S) is a novel procedure with promising short-term results. The long-term outcomes of SADI-S in patients with BMI ≥ 50 kg/m2 are not well described. We aim to compare the safety and efficacy of SADI-S with RYGB in this patient population...

Until now, there has not been organized consensus for standardization in bariatric surgery In Russia. We present the results of the first Bariatric Surgery Consensus Conference conducted in Barnaul (March, 2023). A list of questions was proposed within 6 blocks: 1) general issues of bariatric surgery, 2) sleeve gastrectomy, 3) one-anastomosis gastric bypass («mini-gastric bypass»), 4) Roux-en-Y Gastric Bypass, 5) Single Anastomosis Duodenal Switch and other options for biliopancreatic bypass, 6) rare procedures...

The objective of this study was to evaluate and compare the effectiveness of three different types of bariatric surgeries, namely, sleeve gastrectomy (SG), one-anastomotic gastric bypass (OAGB), and single anastomosis sleeve ileal (SASI) bypass, in the treatment of metabolic syndrome (MS). The optimal approach for managing MS remains uncertain, and thus this study aimed to provide a recent analysis of the efficacy of these surgical procedures. This retrospective study evaluated data of individuals who underwent SG, OAGB, and SASI bypass...

BACKGROUND/AIM: Long-term gastroesophageal reflux (GERD) after gastric bypass for obesity is underestimated. The present study aimed to evaluate the rate of treated GERD and the factors influencing it in a cohort of patients who underwent gastric bypass. PATIENTS AND METHODS: Patients who underwent one-anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) as a primary bariatric procedure between 2010 and 2011 at a French private referral center were included in the study...

This article examines the evolution of bariatric surgery, with a focus on emerging technologies such as robotics and laparoscopy. In the case of gastric bypass, no significant differences have emerged between the two techniques in terms of hospitalization duration, weight loss, weight regain, or 30-day mortality. Robotic surgery, while requiring more time in the operating room, has been associated with lower rates of bleeding, mortality, transfusions, and infections. In revisional bariatric surgery, the robotic approach has shown fewer complications, shorter hospital stays, and a reduced need for conversion to open surgery...

<b><br>Introduction:</b> The rate of revisional surgeries following sleeve gastrectomy (SG) has increased. One-anastomosis gastric bypass (OAGB) appears to have multiple advantages as a primary bariatric procedure. OAGB as revisional surgery is still being investigated.</br> <b><br>Aim:</b> Evaluation of the efficacy and safety of OAGB performed as a post-SG revisional surgery.</br> <b><br>Materials and methods:</b> A single-center, retrospective cohort study was conducted using a routinely collected database of adults undergoing revisional OAGB after SG...

Intestinal malrotation is typically encountered in the first year of life and is rarely seen in adult populations. Herein, we present the case of a 48-year-old woman with a surgical history of laparoscopic Nissen-sleeve gastrectomy before 11 months who was referred to the general surgery service after presenting to the emergency department with acute epigastric abdominal pain for one-day duration. Radiography and a computed tomography (CT) scan of the abdomen revealed a large pneumoperitoneum. Subsequently, a diagnostic laparoscopy was performed, which detected a sealed perforation in the fundus of the wrapped-sleeved stomach, along with an incidental finding of intestinal malrotation...

Single-port or single-incision laparoscopic surgery (SILS) is esteemed for its efficacy in achieving superior postoperative cosmetic outcomes compared to the conventional laparoscopic approach (Behnia-Willison et al. in Aust N Z J Obstet Gynaecol 52:366-370, 2012; Rogula et al. in Obes Surg 24:1102-1108, 2014; Pitot et al. in Surg Endosc 28:3007-3011, 2014). The introduction of SILS for bariatric procedures can be attributed to the pioneering work of Saber in 2008, who initially applied this technique to laparoscopic sleeve gastrectomy (SG), followed by its utilization in laparoscopic adjustable gastric banding (AGB) (Saber et al...

The increased operative time and costs represent the main limitations of robotic technology application to bariatric surgery. Robotic platforms may help the surgeon to overcome the technical difficulties in super-obese (SO, BMI ≥ 50 kg/m2 ) patients, in which multi-quadrant operations could be challenging. We aimed to evaluate the effect of robot-assisted (R) versus laparoscopic (L) approaches in Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI-S) and Roux-en-Y Gastric Bypass (RYGB) in SO and Super-Super Obese (SSO, BMI ≥ 60 kg/m2 ) patients in terms of outcomes and cost-effectiveness...

PURPOSE: Our aim in this study is to assess single anastomosis duodeno-ileal bypass (SADI) as a salvage procedure following sleeve gastrectomy (SG), examining its technical feasibility, outcomes, and potential complications. MATERIALS AND METHODS: A systematic review and meta-analysis were conducted, drawing data from PubMed, Medline, and the Cochrane library. The analysis encompassed 14 studies, involving 1,066 patients. We evaluated operative time, comorbidity resolution (hypertension, dyslipidemia, diabetes), post-operative diarrhea incidence, excess weight loss (EWL) at six, twelve, and twenty-four months, and post-operative leak rates...

BACKGROUND: Rapid adoption of sleeve gastrectomy (SG) in the last decade aptly reflects the desire of patients and surgeons for alternatives to RYGB and DS. While SG provides good outcomes, other options that address specific patient needs are warranted. Recently approved by ASMBS, SADI, and OAGB have garnered increasing interest due to their single anastomosis technique. METHODS: Using the Metabolic and Bariatric Surgery Quality Improvement Program database, we examined laparoscopic and robotic cases from 2018 to 2021 to understand the percentage of primary bariatric surgery cases that are SADI and OAGB...

Bariatric surgery is a well-established treatment for morbid obesity, combining both restrictive and malabsorptive mechanisms to achieve weight loss. Macro and micronutrient deficiencies are some of the most common complications of these operations, which in rare occasions can be unexpected, severe, and difficult to manage. We present a case of severe copper deficiency related myelopathy in a patient post single anastomosis gastric bypass, requiring parenteral copper replacement and eventual reversal. She presented with ascending lower limb paraesthesia and weakness, with copper levels on admission of 4 μmol/l, and ceruloplasmin 94 mg/l...
