Scholtz S, Miras AD, Chhina N, et al., 2014, Obese patients after gastric bypass surgery have lower brain-hedonic responses to food than after gastric banding, Gut, Vol: 63, Pages: 891-902, ISSN: 0017-5749
Objectives Roux-en-Y gastric bypass (RYGB) has greater efficacy for weight loss in obese patients than gastric banding (BAND) surgery. We hypothesise that this may result from different effects on food hedonics via physiological changes secondary to distinct gut anatomy manipulations.Design We used functional MRI, eating behaviour and hormonal phenotyping to compare body mass index (BMI)-matched unoperated controls and patients after RYGB and BAND surgery for obesity.Results Obese patients after RYGB had lower brain-hedonic responses to food than patients after BAND surgery. RYGB patients had lower activation than BAND patients in brain reward systems, particularly to high-calorie foods, including the orbitofrontal cortex, amygdala, caudate nucleus, nucleus accumbens and hippocampus. This was associated with lower palatability and appeal of high-calorie foods and healthier eating behaviour, including less fat intake, in RYGB compared with BAND patients and/or BMI-matched unoperated controls. These differences were not explicable by differences in hunger or psychological traits between the surgical groups, but anorexigenic plasma gut hormones (GLP-1 and PYY), plasma bile acids and symptoms of dumping syndrome were increased in RYGB patients.Conclusions The identification of these differences in food hedonic responses as a result of altered gut anatomy/physiology provides a novel explanation for the more favourable long-term weight loss seen after RYGB than after BAND surgery, highlighting the importance of the gut–brain axis in the control of reward-based eating behaviour.

Rowland SP, Dharmarajah B, Moore HM, et al., 2014, Inferior Vena Cava Filters for Prevention of Venous Thromboembolism in Obese Patients Undergoing Bariatric Surgery: A Systematic Review., Annals of Surgery, ISSN: 1528-1140
Objective: The use of inferior vena cava (IVC) filters for prevention of venous thromboembolism (VTE) in bariatric surgery is a contentious issue. We aim to review the evidence for the use of IVC filters in bariatric surgical patients, describe trends in practice, and discuss challenges in developing evidence-based guidelines.Background: The incidence of VTE in modern bariatric procedures with traditional methods of thromboprophylaxis, such as sequential calf compression devices and perioperative low molecular weight heparin, is approximately 2%.Methods: A systematic review of the literature was conducted according to PRISMA guidelines. We searched Medline up until July 2013 with the terms "bariatric filter" and "gastric bypass filter." Two investigators independently screened search results according to an agreed list of eligibility criteria.Results: Eighteen studies were included. There were no randomized controlled trials. Data from controlled cohort studies suggest that those who undergo IVC filter insertion preoperatively may be at higher risk of developing deep vein thrombosis (DVT) and pulmonary embolism (PE). A small cohort of patients with multiple risk factors for VTE benefitted from reduced PE-related mortality after preoperative IVC filter insertion. Data from 12 case series reporting VTE outcomes from a total of 497 patients who underwent preoperative IVC filter insertion demonstrated DVT rates of 0% to 20.8% and PE rates ranging from 0% to 6.4%.Conclusions: Published data reporting the safety and efficacy of IVC filter use in bariatric surgical patients is highly heterogeneous. There is no evidence to suggest that the potential benefits of IVC filters outweigh the significant risks of therapy.
Awad S, Carter S, Purkayastha S, et al., 2014, Enhanced Recovery After Bariatric Surgery (ERABS): Clinical Outcomes from a Tertiary Referral Bariatric Centre, Obesity Surgery, Vol: 24, Pages: 753-758, ISSN: 1708-0428
There is paucity of data on Enhanced RecoveryAfter Bariatric Surgery (ERABS) protocols. This feasibilitystudy reports outcomes of this protocol utilized within atertiary-referral bariatric centre. Data on consecutive primaryprocedures (laparoscopic gastric bypasses, sleeve gastrectomiesand gastric bands) performed over 9 months within an ERABSprotocol were prospectively recorded. Interventions utilizedincluded shortened preoperative fasts, intra-operative humidification,early mobilization and feeding, avoidance of fluid overload,incentive spirometry, use of prokinetics and laxatives.Data collected included demographics, co-morbidities, morbidity,mortality, length of stay (LOS) and re-admissions. A total of226 procedures (age [mean ± SD], 45±11 years, median [interquartilerange] BMI 44.9 [41.0–49.0] kg/m2) were undertaken:150 (66 %) bypasses, 47 (21 %) sleeves and 29 (13 %)bands. Hypertension, diabetes mellitus, sleep apnea and limitedmobility were present in 40 %, 34 %, 24 % and 9 % of patients,respectively. No anastomotic or staple line leaks/bleeds wereencountered. Ten (4.4 %) patients developed postoperativemorbidity (mainly respiratory complications). One deathoccurred from massive pulmonary embolus in a high-risk patient(despite insertion of preoperative-IVC filter). Respectivemean ± SD LOS for bypasses, sleeves and bands were 1.88±1.12, 2.30±1.69 and 0.69±0.81 days. Successful discharge onthe first postoperative day was achieved in 37 % and 28 % ofbypasses and sleeves, respectively. Day-case gastric bands wereperformed in 48 %. Thirty-day hospital re-admission occurredin six (2.7 %) patients. Applying an ERABS protocol wasfeasible, safe, associated with low morbidity, acceptable LOSand low 30-day re-admission rates. The presence of multiplemedical co-morbidities should not preclude use of an ERABSprotocol within bariatric patients.
