Roux-en-Y gastric bypass versus sleeve gastrectomy: what factors influence patient preference?
Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the most commonly performed bariatric procedures. RYGB involves altered gastrointestinal anatomy and 2 anastomoses, while SG involves gastric resection. When potential patients view images of the procedures, they may perceive RYGB to involve significant risk compared with SG, in which no significant gastrointestinal alterations are depicted. ⋯ Based on this survey, providing evidence-based risks and benefits of a procedure resulted in the majority of respondents choosing RYGB over SG. When procedure images were provided alone, preference for RYGB and SG were similar. There are likely other factors contributing to increasing SG volume aside from patient preference.

Comparative StudyMetabolic comparison of one-anastomosis gastric bypass, single-anastomosis duodenal-switch, Roux-en-Y gastric bypass, and vertical sleeve gastrectomy in rat.
One-anastomosis gastric bypass (OAGB) and single-anastomosis duodenal switch (SADS) have become increasingly popular weight loss strategies. However, data directly comparing the effectiveness of these procedures with Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (SG) are limited. ⋯ These data support the use of the rat for modeling bariatric surgical procedures and highlight the ability of the OAGB to meet or exceed the metabolic improvements of RYGB. These data point to the likelihood that each surgery accomplishes metabolic improvements through both overlapping and distinct mechanisms and warrants further research.

Meta AnalysisPredictors of glycemic control after sleeve gastrectomy versus Roux-en-Y gastric bypass: A meta-analysis, meta-regression, and systematic review.
Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most commonly performed bariatric procedures globally. However, it remains controversial which procedure provides better glycemic control. To identify predictors of glycemic control after SG versus RYGB, a systematic search of PubMed, EMBASE, and the Cochrane Library was conducted up to January 2017 for comparative studies with both SG and RYGB arms for the treatment of type 2 diabetes (T2D). ⋯ The baseline body mass index, duration of T2D, preoperative fasting plasma glucose, and preoperative A1C had predictive value for glycemic control after SG, but only duration of T2D and preoperative A1C were correlated with that after RYGB. These findings showed that the choice of procedure between SG and RYGB predicts no better glycemic control. However, more factors should be considered when SG is recommended to a given patient with diabetes.
