The document compares the length of stay (LOS) for mini-gastric bypass (MGB) surgery to Roux-en-Y gastric bypass (RNY) using data from several large studies. It finds that the median LOS for MGB was 1 day with a mean of 1.2 days, outperforming reported LOS for RNY which averaged 2.4 to 2.7 days. MGB also scored higher on a 30-point assessment of quality measures compared to RNY. The document concludes that LOS is a useful quality metric and that MGB demonstrates superior LOS and outcomes compared to RNY based on available data.
