National introduction of one-anastomosis gastric bypass in the UK National Bariatric Surgery Registry - a cohort study.

Aim: There is a paucity of evidence regarding the national introduction of newer bariatric metabolic surgery procedures. This study assessed the impact of introducing one-anastomosis gastric bypass (OAGB) in bariatric surgical practice in the UK on 30-day postoperative morbidity and early postoperative weight loss.

Methods: Patients who underwent primary BMS in the UK National Bariatric Surgical Registry (2010-2019) were identified.

What is the effect of bariatric surgery on health-related quality of life in people with obesity? Observational cohort analysis of the United Kingdom National Bariatric Surgery Registry.

Background: Previous small studies investigating health-related quality of life (HRQoL) following bariatric surgery have demonstrated heterogenous effects. This study aimed to use National Bariatric Surgery Registry (NBSR) records to investigate the relationship between weight and HRQoL in people undergoing bariatric surgery in the UK.

Materials And Methods: In this observational study using United Kingdom National Bariatric Surgery Registry (NBSR) records between 1st June 2017 and 23rd November 2022, patients undergoing primary bariatric surgery with one baseline and at least one follow-up visit within 1 year from surgery were eligible for inclusion.

Bariatric surgery provision in response to the COVID-19 pandemic: retrospective cohort study of a national registry.

Background: When surgery resumed following the outbreak of the COVID-19 pandemic, guidelines recommended the prioritization of patients with greater obesity-related co-morbidities and/or higher body mass index.

Objective: The aim of this study was to record the effect of the pandemic on total number, patient demographics, and perioperative outcomes of elective bariatric surgery patients in the United Kingdom.

Setting And Methods: The United Kingdom National Bariatric Surgical Registry was used to identify patients who underwent elective bariatric surgery during the pandemic (1 yr from April 1, 2020).

Clinical characteristics of patients undergoing primary bariatric surgery in the United Kingdom based on the National Bariatric Surgery Registry.

Baseline demographic characteristics and operations undertaken for patients having bariatric surgery in the United Kingdom are largely unknown. This study aimed to describe the profile of patients having primary bariatric surgery in the National Health Service (NHS) or by self-pay, and associated operations performed for both pathways. The National Bariatric Surgery Registry dataset for 5 years between January 2015 and December 2019 was used.

Bariatric-metabolic surgery for NHS patients with type 2 diabetes in the United Kingdom National Bariatric Surgery Registry.

Aim: Bariatric-metabolic surgery is approved by the National Institute of Health and Care Excellence (NICE) for people with severe obesity and type 2 diabetes (T2DM) (including class 1 obesity after 2014). This study analysed baseline characteristics, disease severity and operations undertaken in people with obesity and T2DM undergoing bariatric-metabolic surgery in the UK National Health Service (NHS) compared to those without T2DM.

Methods: Baseline characteristics, trends over time and operations undertaken were analysed for people undergoing primary bariatric-metabolic surgery in the NHS using the National Bariatric Surgical Registry (NBSR) for 11 years from 2009 to 2019.

The first international Delphi consensus statement on Laparoscopic Gastrointestinal surgery.

Background: Laparoscopic surgery has almost replaced open surgery in many areas of Gastro-Intestinal (GI) surgery. There is currently no published expert consensus statement on the principles of laparoscopic GI surgery. This may have affected the training of new surgeons.

The first modified Delphi consensus statement on sleeve gastrectomy.

Introduction: Sleeve gastrectomy (SG) is the commonest bariatric procedure worldwide. Yet there is significant variation in practice concerning its various aspects. This paper report results from the first modified Delphi consensus-building exercise on SG.

The first consensus statement on revisional bariatric surgery using a modified Delphi approach.

Background: Revisional bariatric surgery (RBS) constitutes a possible solution for patients who experience an inadequate response following bariatric surgery or significant weight regain following an initial satisfactory response. This paper reports results from the first modified Delphi consensus-building exercise on RBS.

Methods: We created a committee of 22 recognised opinion-makers with a special interest in RBS.

Exploring the Patient-Reported Impact of the Pharmacist on Pre-bariatric Surgical Assessment.

Background: The effects of surgical procedures and the need for life-long nutrient supplementation may impact on medication regimes, requiring changes to dosage and formulation of medicines, which can be difficult for patients following surgery. Our pre-surgical assessment pathway involves a pharmacist with specialist knowledge of bariatric surgery, to help prepare patients for these changes.

Objective: To explore the patient-reported impact of the specialist bariatric pharmacist in pre-surgical assessment.

Practices Concerning Revisional Bariatric Surgery: a Survey of 460 Surgeons.

Background: There is currently little evidence available on various aspects of Revisional Bariatric Surgery (RBS) and no published consensus amongst experts. The purpose of this study was to understand variation in practices concerning RBS.

Methods: Bariatric surgeons from around the world who perform RBS were invited to participate in a questionnaire-based survey on SurveyMonkey®.

Oral Vitamin B Supplementation After Roux-en-Y Gastric Bypass: a Systematic Review.

Background: Many respectable guidelines recommend lifelong vitamin B injections for Roux-en-Y gastric bypass (RYGB) patients in the absence of lack of consensus on the efficacy of oral route of prophylaxis and the appropriate doses needed for this purpose. The purpose of this review was to examine the published English language scientific literature in accordance with PRISMA principles to find out if orally given vitamin B is adequate for prophylactic purposes in RYGB patients and the appropriate dosages needed for this purpose if it is.

Methods: We examined the PubMed database for all English language articles examining various doses of oral vitamin B supplementation after proximal RYGB in adult patients.

The First Consensus Statement on One Anastomosis/Mini Gastric Bypass (OAGB/MGB) Using a Modified Delphi Approach.

Background: An increasing number of surgeons worldwide are now performing one anastomosis/mini gastric bypass (OAGB/MGB). Lack of a published consensus amongst experts may be hindering progress and affecting outcomes. This paper reports results from the first modified Delphi consensus building exercise on this procedure.

Perioperative Practices Concerning One Anastomosis (Mini) Gastric Bypass: A Survey of 210 Surgeons.

Background: There is currently little evidence available on the perioperative practices concerning one anastomosis/mini gastric bypass (OAGB/MGB) and no published consensus amongst experts. Even the published papers are not clear on these aspects. The purpose of this study was to understand various perioperative practices concerning OAGB/MGB.

Impact of biliopancreatic limb length on severe protein-calorie malnutrition requiring revisional surgery after one anastomosis (mini) gastric bypass.

Background: One anastomosis (mini) gastric bypass (OAGB) is believed to be more malabsorptive than Roux-en-Y gastric bypass. A number of patients undergoing this procedure suffer from severe protein-calorie malnutrition requiring revisional surgery. The purpose of this study was to find the magnitude of severe protein-calorie malnutrition requiring revisional surgery after OAGB and any potential relationship with biliopancreatic limb (BPL) length.

Bariatric Surgery in Septuagenarians: a Comparison with <60 Year Olds.

Introduction: There is reluctance amongst many healthcare professionals to offer bariatric surgery to septuagenarians. There is only one study in the scientific literature specifically describing any experience with this group of patients and none that compares the outcomes in this group with younger patients.

Methods: We retrospectively examined our prospective database to identify all those who were >70 years old at the time of bariatric surgery.

Conversion of Sleeve Gastrectomy to Roux-en-Y Gastric Bypass is Effective for Gastro-Oesophageal Reflux Disease but not for Further Weight Loss.

Introduction: Inadequate weight loss (IWL)/weight regain (WR) and gastro-esophageal reflux disease (GERD), unresponsive to medical management, are two most common indications for conversion of sleeve gastrectomy (SG) to Roux-en-Y gastric bypass (RYGB). This study reports detailed outcomes of conversion of SG to RYGB for these two indications separately.

Methods: We interrogated our prospectively maintained database to identify patients who underwent a conversion of their SG to RYGB in our unit.

Ascertaining the Place of Social Media and Technology for Bariatric Patient Support: What Do Allied Health Practitioners Think?

Background: There is an increasing presence of patient-led social media, mobile apps and patient support technology, but little is known about the role of these in the support of bariatric surgery patients in the UK. This study aimed to seek the views of allied health professionals (AHPs) working in bariatric surgical teams to understand their current perceptions of the role of social media, mobile apps and patient-support technology within bariatric surgery in the UK.

Methods: A confidential, printed survey was distributed to the AHPs at the British Obesity and Metabolic Surgery Society (BOMSS) 7th Annual Scientific Conference in January 2016.

Management of super-super obese patients: comparison between one anastomosis (mini) gastric bypass and Roux-en-Y gastric bypass.

Background: Gastric bypass can be technically challenging in super-super obese patients. Both Roux-en-Y gastric bypass (RYGB) and one anastomosis (mini) gastric bypass (OAGB/MGB) have been described in these patients, but direct comparisons are lacking. The purpose of this study was to compare the early outcomes with these two procedures in patients with body mass index (BMI) of ≥60 kg/m in our unit.

Zinc Deficiency after Gastric Bypass for Morbid Obesity: a Systematic Review.

Up to 50% of patients have zinc deficiency before bariatric surgery. Roux-en-Y gastric bypass (RYGB) is the commonest bariatric procedure worldwide. It can further exacerbate zinc deficiency by reducing intake as well as absorption.

Criteria for Inclusion of Newer Bariatric and Metabolic Procedures into the Mainstream: a Survey of 396 Bariatric Surgeons.

Background: There is currently no consensus on the criteria for inclusion of new bariatric procedures into routine clinical practice. This study canvasses bariatric surgeons in an attempt to define these criteria.

Methods: Bariatric Surgeons from around the world were invited to participate in a questionnaire-based survey on SurveyMonkey ®.

Monitoring of Liver Function Tests after Roux-en-Y Gastric Bypass: An Examination of Evidence Base.

There is no consensus on the monitoring of liver function tests after Roux-en-Y gastric bypass (RYGB). Since the main objective of such monitoring would be to diagnose early those who will eventually develop liver failure after RYGB, we performed a systematic review on this topic. An extensive search of literature revealed only 10 such cases in 6 published articles.
