Background Bariatric surgery in patients with BMI over 50 kg/m2 is a challenging task. The aim of this study was to address main issues regarding perioperative management of these patients by using a worldwide survey. Methods An online 48-item questionnaire-based survey on perioperative management of patients with a BMI superior to 50 kg/m2 was ideated by 15 bariatric surgeons from 9 different countries. The questionnaire was emailed to all members of the International Federation of Surgery for Obesity (IFSO). Responses were collected and analyzed by the authors. Results 789 bariatric surgeons from 73 countries participated in the survey. Most surgeons (89.9%) believed that metabolic/bariatric surgery (MBS) on patients with BMI over 50 kg/m2 should only be performed by expert bariatric surgeons. Half of the participants (55.3%) believed that weight loss must be encouraged before surgery and 42.6% of surgeons recommended an excess weight loss of at least 10%. However, only 3.6% of surgeons recommended the insertion of an Intragastric Balloon as bridge therapy before surgery. Sleeve Gastrectomy (SG) was considered the best choice for patients younger than 18 or older than 65 years old. SG and One Anastomosis Gastric Bypass were the most common procedures for individuals between 18 and 65 years. Half of the surgeons believed that a 2-stage approach should be offered to patients with BMI > 50 kg/m2, with SG being the first step. Postoperative thromboprophylaxis was recommended for 2 and 4 weeks by 37.8% and 37.7% of participants, respectively. Conclusion This survey demonstrated worldwide variations in bariatric surgery practice regarding patients with a BMI superior to 50 kg/m2. Careful analysis of these results is useful for identifying several areas for future research and consensus building.

Background The coronavirus disease 2019 (COVID-19) pandemic led to a worldwide suspension of bariatric and metabolic surgery (BMS) services. The current study analyses data on patterns of service delivery, recovery of practices, and protective measures taken during the COVID-19 pandemic by bariatric teams. Materials and Methods The current study is a subset analysis of the GENEVA study which was an international cohort study between 01/05/2020 and 31/10/2020. Data were specifically analysed regarding the timing of BMS suspension, patterns of service recovery, and precautionary measures deployed. Results A total of 527 surgeons from 439 hospitals in 64 countries submitted data regarding their practices and handling of the pandemic. Smaller hospitals (with less than 200 beds) were able to restart BMS programmes more rapidly (time to BMS restart 60.8 ± 38.9 days) than larger institutions (over 2000 beds) (81.3 ± 30.5 days) (p = 0.032). There was a significant difference in the time interval between cessation/reduction and restart of bariatric services between government-funded practices (97.1 ± 76.2 days), combination practices (84.4 ± 47.9 days), and private practices (58.5 ± 38.3 days) (p Precautionary measures adopted included patient segregation, utilisation of personal protective equipment, and preoperative testing. Following service recovery, 40% of the surgeons operated with a reduced capacity. Twenty-two percent gave priority to long waiters, 15.4% gave priority to uncontrolled diabetics, and 7.6% prioritised patients requiring organ transplantation. Conclusion This study provides global, real-world data regarding the recovery of BMS services following the COVID-19 pandemic. Graphical abstract

One anastomosis/mini gastric bypass (OAGB/MGB) is up to date the third most performed obesity and metabolic procedure worldwide, which recently has been endorsed by ASMBS. The main criticisms are the risk of bile reflux, esophageal cancer, and malnutrition. Although IFSO has recognized this procedure, guidance is needed regarding selection criteria. To give clinicians a daily support in performing the right patient selection in OAGB/MGB, the aim of this paper is to generate clinical guidelines based on an expert modified Delphi consensus.A committee of 57 recognized bariatric surgeons from 24 countries created 69 statements. Modified Delphi consensus voting was performed in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was considered to indicate a consensus.Consensus was achieved for 56 statements. Remarkably, ≥ 90.0% of the experts felt that OAGB/MGB is an acceptable and suitable option "in patients with Body mass index (BMI) 70, BMI 60, BMI 50 kg/mPatient selection in OAGB/MGB is still a point of discussion among experts. There was consensus that OAGB/MGB is a suitable option in elderly patients, patients with low BMI (30-35 kg/m

Although laparoscopic adjustable gastric band (LAGB) placement appears as a safe and reproducible procedure, serious complications can occur. We present a patient with fever, dysphagia, epigastric pain, and port site inflammation. Esophagogastroduodenoscopy and computed tomography (CT) scan diagnosed esophageal erosion of the gastric band. An endoscopic retrieval was proposed to avoid accessing the abdominal cavity and mediastinum, reduce recovery time, and minimize complications. The patient successfully underwent the procedure with immediate improvement of symptoms and discharge on the seventh postoperative day. This article aims to report the first clinical case of an esophageal erosion of LAGB completely treated with an endoscopic approach.

Introduction: Roux-en-Y gastric bypass (RYGB) remains among the most widely performed bariatric procedures. A significant decline in its indication has been observed due to weight regain and reappe...

Bariatric surgery is the most effective treatment for morbid obesity and its associated comorbidities. To ensure long-term postoperative success and safety, patients and physicians must be informed about the related commitment required, regarding supplementation, follow-up, and lifestyle changes. Hypoabsorptive procedures have demonstrated to be most effective in the long term when compared with other procedures. As morbid obesity is a chronic disease, these techniques should be applied as long as postoperative premises can be responsibly carried out.

The worldwide acceptance of bariatric surgery is a result of its well-known results, but despite making our greatest efforts to achieve near-zero complications, some may appear. A new challenge starts when this happens, and the medical team must be prepared to manage them appropriately.

There is no doubt that obesity is an epidemic that affects not only developed but also underdeveloped countries. This “globalization” of the disease has led to the current surgery, as a therapeutic method of this pathology, to evolve in terms of its techniques implemented to patients [1]. Within these evolutions is the single anastomosis gastric bypass (SAGB) too called one-anastomosis gastric bypass (OAGB), which although it has few years of application, many centers of the world have adopted it successfully with good results. This technique has about 15 years, but it is in the last 5 years in which it showed a surprising development [2]. It consists of performing a gastric pouch and a single gastroenteroanastomosis, without Roux-en-Y reconstruction. In this way surgery is achieved with equal or better results with a less anastomosis and all that implies.

In laparoscopy, it often is the case that port sites are enlarged for specimen extraction. This leads to higher risk of trocar site complications, such as infection or incisional hernia. Natural orifice surgery (NOTES) is beneficial for minimizing these complications, and this is emphasized when the extracted specimen is of large volume. We have been using transgastric technique for appendectomy, cholecystectomy, and laparoscopic sleeve gastrectomy (LSG). Of these transgastric operations, we focus on the one with relatively large-organ extraction: LSG with transoral remnant extraction (TORE). We describe the details and feasibility of this procedure and compare the outcomes to conventional LSG. All patients undergoing LSG were considered candidates for TORE and were consented for this procedure if interested after an informed discussion. Eighteen LSGs with TORE (TORE group) and ten conventional LSGs (non-TORE group) were performed from August 2010 to March 2011. We retrospectively compared these two groups for the age, sex, preoperative body mass index, operating room time, hospital stay, excess weight loss (EWL), and trocar site complications. Laparoscopic sleeve gastrectomy with TORE consists of conventional LSG and transgastric retrieval of the resected stomach. The procedure exceeds exactly the same manner as conventional LSG until the initial stapling of the stomach. For TORE, the gastrectomy is initiated 5 cm proximal to the pylorus than usual LSG to save the space for the gastrotomy used for specimen retrieval. After the gastrectomy is completed, the full thickness of the distal most part of the staple line is incised open as wide as 2 cm by using electric cautery or ultrasonic dissector. A flexible upper endoscope, which has been in the stomach already as a bougie for gastrectomy, is then guided into the peritoneal cavity through the gastrotomy. The specimen is grasped endoscopically with a snare and extracted transorally. Following this, the gastrotomy is closed laparoscopically. The final shape of the gastric sleeve is identical to the one of conventional LSG. There was no significant difference between the TORE and the non-TORE group for patients’ profile, operating room time, hospital stay, and EWL. Neither group has experienced perioperative complications. All specimens were extracted readily and safely in the TORE group. Of the ten cases in the non-TORE group, four required extension of the trocar site. No trocar site complications were found in the TORE group, whereas the extended trocar site developed panniculitis in two cases of the non-TORE group; one required panniculectomy for refractory induration. TORE can be safely and easily performed by surgeons with laparoscopic and endoscopic skill, and with commonly available instruments. While producing identical outcomes, our initial experience with the TORE technique demonstrates an advantage over traditional LSG, because it minimizes trocar site complications. Transgastric organ extraction is potentially applicable to other large-organ extractions in laparoscopic surgery without excessive risk or resources. Larger case volume and longer follow-up period is awaited.
