Randomized Controlled Trial
Systemic lidocaine to improve quality of recovery after laparoscopic bariatric surgery: a randomized double-blinded placebo-controlled trial.
Few multimodal strategies to minimize postoperative pain and improve recovery have been examined in morbidly obese patients undergoing laparoscopic bariatric surgery. The main objective of this study was to evaluate the effect of systemic intraoperative lidocaine on postoperative quality of recovery when compared to saline. ⋯ Systemic lidocaine improves postoperative quality of recovery in patients undergoing laparoscopic bariatric surgery. Patients who received lidocaine had a lower opioid consumption which translated to a better quality of recovery.

Laparoscopic Roux-en-Y gastric bypass (LRYGBP) reduces appetite and induces significant and sustainable weight loss. Circulating gut hormones changes engendered by LRYGBP are implicated in mediating these beneficial effects. Laparoscopic sleeve gastrectomy (LSG) is advocated as an alternative to LRYGBP, with comparable short-term weight loss and metabolic outcomes. ⋯ A similar increase in post-prandial fullness was observed post-surgery following both procedures. LRYGBP and LSG produced comparable enhanced satiety and weight loss. However, LSG and LRYGBP differentially altered gut hormone profiles.

Case Reports
Can bariatric surgery be performed safely in patients with severe treatment-resistant asthma?
Obesity-associated severe asthma is a distinct phenotype characterised by resistance to standard asthma therapies. Bariatric surgery appears to be a viable alternative for those who have failed trials of traditional weight loss methods. ⋯ We describe three patients with treatment-resistant obesity-associated severe asthma who underwent bariatric surgery without complications due to the multidisciplinary perioperative planning and care involved in these complex cases. All three patients showed improvements in asthma control and reduction in maintenance medication use post-surgery.

Roux-en-Y gastric bypass (RYGB) may reduce the absorption of iron, but the extent to which this absorption is impeded is largely unknown. First, we determined the prevalence of iron deficiency following RYGB and explored the risk factors for its development. Second, we examined to what extent oral iron supplements are absorbed after RYGB. ⋯ Iron deficiency is extremely frequent after RYGB and is linked with different risk factors. Iron supplementation seems essential, but the effect of oral tablets may be limited as absorption of oral iron supplements is insufficient post-RYGB.

Gastric electrical stimulation (GES) has been proposed as a promising therapeutic option in treating obesity for 20 years. Currently, the available device of GES cannot meet the clinical needs. The purpose of this study is to verify the effect of a new type of adjustable gastric electrical stimulator in reducing food intake and body weight. ⋯ Food intake and body weight of dogs are significantly reduced by adjustable GES. Individual parameters and resistance during GES are required to be considered. The new adjustable device may have good prospects of clinical application for obesity.
