(HealthDay News) – Laparoscopic Roux-en-Y gastric bypass (LRYGB) is safer than open Roux-en-Y gastric bypass (ORYGB), even after adjusting for patient-level variables.

Gaurav Banka, MD, from Stanford University in California, and colleagues retrospectively analyzed outcome data from the Nationwide Inpatient Sample for patients undergoing ORYGB (41,094) and LRYGB (115,177) from 2005–2007.

The researchers found that LRYGB was significantly more commonly performed than ORYGB (72 vs. 28%) and was significantly more likely to be performed at high-volume hospitals (69 vs. 61%). More ORYGB patients were Medicare (9.3 vs. 7.1%) and Medicaid (10.4 vs. 5.9%) recipients, compared with LRYGB patients. ORYGB patients were more likely to be discharged with non-routine dispositions (7.7 vs. 2.4%), were more likely to die (0.2 vs. 0.1%), and had one or more complications (18.7 vs. 12.3%), compared with LRYGB patients. ORYGB patients had higher rates of all Patient Safety Indicators, a significantly longer median length of stay (3.5 vs. 2.4 days), and significantly higher total charges ($35,018 vs. $32,671), compared to LRYGB patients.

"In this population-based study, LRYGB provided greater safety than ORYGB even after adjusting for patient-level socioeconomic and comorbidity differences," the authors write.
