Laparoscopic Safer Than Open Surgery for Gastric Bypass
Findings true even after adjusting for patient-level socioeconomic and comorbidity factors
THURSDAY, June 21 (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, according to research published in the June issue of the Archives of Surgery.
Gaurav Banka, M.D., 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 to 2007.
The researchers found that LRYGB was significantly more commonly performed than ORYGB (72 versus 28 percent) and was significantly more likely to be performed at high-volume hospitals (69 versus 61 percent). More ORYGB patients were Medicare (9.3 versus 7.1 percent) and Medicaid (10.4 versus 5.9 percent) recipients, compared with LRYGB patients. ORYGB patients were more likely to be discharged with non-routine dispositions (7.7 versus 2.4 percent), were more likely to die (0.2 versus 0.1 percent), and had one or more complications (18.7 versus 12.3 percent), compared with LRYGB patients. ORYGB patients had higher rates of all Patient Safety Indicators, a significantly longer median length of stay (3.5 versus 2.4 days), and significantly higher total charges ($35,018 versus $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.
