INTRODUCTION: The use of robotics in bariatric surgery is increasing worldwide, with the main objective of reducing complications and optimising surgical outcome. This study presents a single centre 1.5-year experience and clinical outcome with robotic gastric bypass. METHODS: A retrospective review was performed of 42 consecutive patients who underwent a robotic gastric bypass. Patient files were analysed to obtain patient characteristics, weight loss results and per- and postoperative morbidity. RESULTS: In 32/42 patients, a primary gastric bypass was performed, the remaining 10 procedures were revision cases. Mean start weight was 111.1 (+/- 20.5) kg, mean start BMI was 39.7 (+/- 5.6) kg/m2. Almost half of the patients presented with pre-existing comorbidities.  After a mean follow-up of 9.1 (+/-5.2) months, mean body mass index was 30.16 (+/-5.3) kg/m2 with a percentage excess weight loss of 66.16 (+/- 43.6)%. There were no conversions, no leaks and no mortality. Two patients presented with minor complications; one infected hematoma and one anastomotic ulcer. Mean length of stay in the hospital was 2.8 (2-5) days. All but one patients were satisfied with the weight loss result. CONCLUSION: The robotic gastric bypass is a safe and reproducible approach to treat morbid obesity. A secure handsewn gastrojejunal anastomosis, quick recovery and better ergonomics are the main advantages of this technique.

Abstract Purpose The treatment of people with severe obesity and BMI > 50 kg/m2 is challenging. The present study aims to evaluate the short and mid-term outcomes of one anastomosis gastric bypass (OAGB) with a biliopancreatic limb of 150 cm as a primary bariatric procedure to treat those people in a referral center for bariatric surgery. Material and Methods Data of patients who underwent OAGB for severe obesity with BMI > 50 kg/m2 between 2010 and 2017 were collected prospectively and analyzed retrospectively. Follow-up comprised clinical and biochemical assessment at 1, 3, 6, 12, 18, and 24 months postoperatively, and once a year thereafter. Results Overall, 245 patients underwent OAGB. Postoperative mortality was null, and early morbidity was observed in 14 (5.7%) patients. At 24 months, the percentage total weight loss (%TWL) was 43.2 ± 9, and percentage excess weight loss (%EWL) was 80 ± 15.7 (184 patients). At 60 months, %TWL was 41.9 ± 10.2, and %EWL was 78.1 ± 18.3 (79 patients). Conversion to Roux-en-Y gastric bypass was needed in three (1.2%) patients for reflux resistant to medical treatment. Six patients (2.4%) had reoperation for an internal hernia during follow-up. Anastomotic ulcers occurred in three (1.2%) patients. Only two patients (0.8%) underwent a second bariatric surgery for insufficient weight loss. Conclusion OAGB with a biliopancreatic limb of 150 cm is feasible and associated with sustained weight loss in the treatment of severe obesity with BMI > 50 kg/m2. Further randomized studies are needed to compare OAGB with other bariatric procedures in this setting. Graphical abstract

Sustained Weight Loss

<b><i>Objectives:</i></b> The growing prevalence of obesity rates worldwide is associated with an upsurge in its comorbidities, particularly type 2 diabetes mellitus (T2DM). Bariatric surgery is a proven treatment modality for producing sustained weight loss and resolution of associated T2DM providing marked improvement in quality of life with rapid recovery. This study aims to investigate the effects of laparoscopic sleeve gastrectomy (LSG), Roux-en-Y gastric bypass (RYGB), and mini-gastric bypass (MGB) on obese patients suffering from T2DM in the Indian population and their long-term association with regard to diabetes remission, resolution of comorbidities, and percentage EWL. <b><i>Methods:</i></b> Retrospective data of obese patients with T2DM (preoperative BMI 45.37 ± 8.1) who underwent bariatric surgery (RYGB, LSG, and MGB) were analyzed in this study over a period of 9 years. The mean follow-up period was 2.2 years. Following surgery, the clinical outcome on BMI, resolution of percentage weight loss, and T2DM were studied. The predictive factors of diabetic remission after surgery were determined. Student’s <i>t</i> test and ANOVA and McNemar’s test were applied. <b><i>Results:</i></b> Out of a total of 274 patients, complete remission of T2DM was achieved in 52.9% (<i>n</i> = 145) with mean fasting blood glucose and glycated hemoglobin values being 6.1 ± 0.769 (<i>p</i> = 0.00) at 1 year after surgery. The independent predictive factors of remission were age, gender, BMI, preoperative comorbidities, and % EWL. Gender had no correlation with the chance of achieving disease remission. <b><i>Conclusion:</i></b> Based on our results, bariatric surgery proves to be a successful treatment option resulting in sustained weight loss in obese patients suffering from T2DM. It is found to be beneficial for the long-term resolution of T2DM and improving comorbidities such as hypertension and dyslipidemia. The outcome of the different surgical methods is found to be similar for all patients irrespective of the independent predictors of complete remission.

Abstract Introduction Patients with low socioeconomic status have been reported to have poorer outcome than those with a high socioeconomic status after several types of surgery. The influence of socioeconomic factors on weight loss after bariatric surgery remains unclear. The aim of the present study was to evaluate the association between socioeconomic factors and postoperative weight loss. Materials and methods This was a retrospective, nationwide cohort study with 5-year follow-up data for 13,275 patients operated with primary gastric bypass in Sweden between January 2007 and December 2012 (n = 13,275), linking data from the Scandinavian Obesity Surgery Registry, Statistics Sweden, the Swedish National Patient Register, and the Swedish Prescribed Drugs Register. The assessed socioeconomic variables were education, profession, disposable income, place of residence, marital status, financial aid and heritage. The main outcome was weight loss 5 years after surgery, measured as total weight loss (TWL). Linear regression models, adjusted for age, preoperative body mass index (BMI), sex and comorbid diseases were constructed. Results The mean TWL 5 years after surgery was 28.3 ± 9.86%. In the adjusted model, first-generation immigrants (%TWL, B −2.4 [95% CI −2.9 to −1.9], p < 0.0001) lost significantly less weight than the mean, while residents in medium-sized (B 0.8 [95% CI 0.4–1.2], p = 0.0001) or small towns (B 0.8 [95% CI 0.4–1.2], p < 0.0001) lost significantly more weight. Conclusions All socioeconomic groups experienced improvements in weight after bariatric surgery. However, as first-generation immigrants and patients residing in larger towns (>200,000 inhabitants) tend to have inferior weight loss compared to other groups, increased support in the pre- and postoperative setting for these two groups could be of value. The remaining socioeconomic factors appear to have a weaker association with postoperative weight loss.

Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in bariatric surgery. The aim of this study was to evaluate the effect of patient characteristics, payer type, comorbidities, and surgical techniques on development of VTE in bariatric surgery. Using the National Inpatient Sample (NIS) database from 2006 to 2008, clinical data of 304,515 morbidly obese patients who underwent bariatric surgery were examined. Multiple regression analysis was performed to identify factors predictive of VTE. The overall rate of in-hospital VTE was 0.17 per cent, with the highest rate of VTE observed in open gastric bypass (0.45%). The VTE rate was significantly lower in laparoscopic compared with open gastric bypass (0.13% vs 0.45%, respectively, P < 0.01) and in nongastric bypass compared with gastric bypass procedures (0.06% vs 0.21%, respectively, P < 0.01). Alcohol abuse [odds ratio (OR): 8.7], open operation (OR: 2.5), gastric bypass procedures (OR: 2.4), renal failure (OR: 2.3), congestive heart failure (OR: 2.0), male gender (OR: 1.5), and chronic lung disease (OR: 1.4) were associated with a higher rate of VTE. This study identified several significant risk factors for development of VTE in bariatric surgery. To minimize the risk of VTE, surgeons may consider these factors in selection of appropriate prophylaxis and bariatric surgical options.
