Meta Analysis Comparative StudyAnemia, iron and vitamin B12 deficiencies after sleeve gastrectomy compared to Roux-en-Y gastric bypass: a meta-analysis.
The effective treatment of postoperative anemia and nutritional deficiencies is critical for the successful management of bariatric patients. However, the evidence for nutritional risk or support of bariatric patients remains scarce. The aims of this study were to assess current evidence of the association between 2 methods of bariatric surgery, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), and postoperative anemia and nutritional deficiencies. ⋯ The authors' findings suggest that SG is more beneficial than RYGB with regard to postoperative vitamin B12 deficiency risk, whereas the 2 methods are comparable with regard to the risk of postoperative anemia and iron deficiency. Postoperative prophylactic iron and B12 supplementation, in addition to general multivitamin and mineral supplementation, is recommended based on the comparable deficiency risk of the 2 methods as indicated by subgroup analysis.

Review Comparative StudyComparison of laparoscopic sleeve gastrectomy leak rates in four staple-line reinforcement options: a systematic review.
The study compared laparoscopic sleeve gastrectomy (LSG) staple-line leak rates of 4 prevalent surgical options: no reinforcement, oversewing, nonabsorbable bovine pericardial strips (BPS), and absorbable polymer membrane (APM). ⋯ Systematic review of 88 included studies representing 8,920 patients found that the leak rate in LSG was significantly lower using APM staple-line reinforcement than oversewing, BPS reinforcement, or no reinforcement.

Review Meta AnalysisInferior vena cava filters and postoperative outcomes in patients undergoing bariatric surgery: a meta-analysis.
Background: Pulmonary embolism(PE)accounts for almost 40% of perioperative deaths after bariatric surgery. Placement of prophylactic inferior vena cava(IVC) filter before bariatric surgery to improve outcomes has shown varied results. We performed a meta-analysis to evaluate post- operative outcomes associated with the preoperative placement of IVC filters in these patients. ⋯ Conclusions: Placement of IVC filter before bariatric surgery Is associated with higher risk of postoperative DVT and mortality. A similar risk of PE inpatients with and without IVC filter placement cannot exclude a benefit, given the potential large imbalance in risk at baseline. Ran- domized trials are needed before IVC placement can be recommended. (SurgObesRelatDis 2015;11:268-269.) r 2015 American Society for Metabolic and Bariatric Surgery.
