“…Bariatric surgery has proven to be the most efficient method of maintained weight loss; however, it is not without risks [ 1 – 3 ]. Super-obese patients (BMI > 50 mg/kg 2 ) are at higher risk of post-operative complications; this may be related to the presence of associated comorbidities such as type 2 diabetes, hypertension, ischaemic heart disease and obstructive sleep apnoea [ 4 ]. A validated scale to predict post-operative risk is obesity surgery mortality risk score (OS-MRS) which classifies patients into low-, intermediate- and high-risk groups based on the presence of risk factors [ 5 , 6 ] [Table 1 ].…”

Pre-operative weight reduction may reduce morbidity and mortality in these patients undergoing bariatric surgery [ 7 , 8 ].…”

BackgroundObesity surgery mortality risk scoring system (OS-MRS) classifies patients into high, intermediate and low risk, based on age, body mass index, sex and other comorbidities such as hypertension and history of pulmonary embolism. High-risk patients not only have a higher mortality but are more likely to develop post-operative complications necessitating intervention or prolonged hospital stay following bariatric surgery. Endoscopically placed duodenal-jejunal bypass sleeve (Endobarrier) has been designed to achieve weight loss and improve glycaemic control in morbidly obese patients with clinically proven effectiveness.The aim of this study was to assess if pre-operative insertion of endobarrier in high-risk patients can decrease morbidity and length of stay after bariatric surgery.Materials and MethodsBetween 2012 and 2014, a cohort of 11 high-risk patients had an Endobarrier inserted (E&BS group) for 1 year prior to definitive bariatric surgery. These patients were compared against a similar group undergoing primary bariatric surgery (PBS group) during same duration. The two groups were matched for age, gender, body mass index, comorbidities, surgical procedure and OS-MRS using propensity score matching. Outcome measures included operative time, morbidity, length of stay, intensive therapy unit (ITU) stay, readmission rate, percentage excess weight loss (%EWL) and percentage total weight loss (%TWL).ResultsPatient characteristics and OS-MRS were similar in both groups (match tolerance 0.1). There was no significant difference in total length of stay, readmission rate, %EWL and %TWL. Operative time, ITU stay, post-operative complications and severity of complications were significantly less in the E&BS group (p < 0.05) with significant likelihood of planned ITU admissions in the PBS group (p < 0.05).ConclusionEndobarrier could be considered as a pre bariatric surgical intervention in high-risk patients. It may result in improved post-operative outcomes in high-risk bariatric patients.
