Metabolic bariatric surgery generates substantial, sustained weight loss and health improvement in a real-world setting.

Background: To determine if the positive outcomes from clinical trials regarding the safety and efficacy of metabolic bariatric surgery are reproducible at a national level.

Methods: A longitudinal registry-based observation study with data collected from all persons undergoing metabolic bariatric surgery in Australia from 28 February 2012-31 December 2021 including data from 122,567 index patients who underwent 134,625 completed bariatric procedures.

Main Outcomes And Measures: Defined adverse outcomes at 90-days (unplanned readmission, intensive care admission and re-operation; death), annual change in weight (percent total body weight loss (TBWL)), diabetes treatment and need for re-operation.

Long-term accuracy of the National Emergency Laparotomy Audit risk score: Analysis of the impact of comorbidities on mortality 5 years after emergency laparotomy.

Background: The National Emergency Laparotomy Audit (NELA) risk prediction tool has demonstrated superiority in predicting 30-day mortality after emergency laparotomy (EL). The aim of our study was to evaluate the accuracy of NELA in calculating long-term (5 year) mortality and determine factors predicting long-term risk of death after EL.

Methods: This retrospective cohort study included consecutive patients who underwent EL for any indication other than trauma between May 2012 and June 2017 at a large tertiary and academic teaching center.

The safety, tolerability and clinical impact of pre-operative very low-calorie diet prior to non-bariatric abdominal surgery: a systematic review.

Background: The use of pre-operative very low-calorie diets (VLCD) is established within bariatric and gallbladder surgery. However, their use in patients with high BMI and hepatic steatosis (HS) requiring upper abdominal procedures is unclear. This review aims to assess the safety, adherence, and outcomes of a pre-operative VLCD prior to non-bariatric elective surgery.

Protocol for a feasibility multi-centre randomised controlled trial of a pre-operative two-week very low-calorie diet to reduce steatosis prior to liver resection (RESOLVE).

Background: Hepatic steatosis (HS) increases morbidity and mortality associated with liver surgery (LS). Furthermore, patients with HS are more likely to require a blood transfusion, which is associated with worse short and long-term outcomes. Patients with HS requiring LS receive no specific dietary treatment or advice.

Frailty and Long-Term Mortality Following Emergency Laparotomy: A Comparison Between the 11-Item and 5-Item Modified Frailty Indices.

Introduction: Emergency laparotomy (EL) is a high-risk operation which is increasingly performed on an aging patient population. Objective frailty assessment using a validated index has the potential to improve preoperative risk stratification. This study aimed to assess the correlation between frailty and long-term mortality and morbidity outcomes for older EL patients.
