Bariatric surgery results: reporting clinical characteristics and adverse outcomes from an integrated healthcare delivery system.

BACKGROUND: Limited data have been reported on bariatric surgery within a large, high-volume regional multicenter integrated healthcare delivery system.

OBJECTIVES: Review clinical characteristics and short- and intermediate-term outcomes and adverse events from a bariatric surgery program within an integrated healthcare delivery system.

SETTING: Single high-volume, multicenter regional integrated healthcare delivery system.

METHODS: Adult patients who underwent primary bariatric surgery during 2010-2011 were reviewed. Clinical characteristics, outcomes, and weight loss results were extracted from the electronic medical record.

RESULTS: A total of 2399 patients were identified within the study period. The 30-day rates of clinical outcomes for Roux-en-Y gastric bypass (RYGB; n = 1313) and sleeve gastrectomy (SG; n = 1018) were 2.9% for readmission, 3.0% for major complications, .8% for reoperation, and 0% for mortality. One-year and 2-year weight loss results were as follows: percent weight loss (%WL) was 31.4 (±SD 8.5) and 34.2±12.0% for SG and 34.1±9.3 and 39.1±11.9 for RYGB; percent excess weight loss (%EBWL) was 64.2±18.0 and 69.8±23.7 for SG and 68.0±19.3 and 77.8±23.7 for RYGB; percent excess body mass index loss (%EBMIL) was 72.9±21.0 and 77.7±22.4 for SG and 76.6±22.1% and 85.6±21.6 for RYGB. Follow-up for each procedure at 1 year was 76% for SG (n = 778) and 80% for RYGB (n = 1052) and at 2 years was 65% for SG (n = 659) and 67% for RYGB (n = 875).

CONCLUSIONS: A large regional high-volume multicenter bariatric program within an integrated healthcare delivery system can produce excellent short-term results with low rates of short- and intermediate-term adverse outcomes.
