Abstract
follow-up of 17.2 months, the % excess weight loss (EWL) of RYGB, LSG and LAGB was 43.6%, 37.4% EWL, and 23.3% EWL, respectively. 80% of our patient population had OA prior to surgery, making OA the most common ORC in our study. All bariatric surgery procedures produced statistically significant ORC resolution and AORC scorechange for all 10 documented comorbidities (p < 0.0001). Resolution of OA, HTN, HLD, and LEE was found to be significantly different between surgery types (p < 0.05): The percentage of patients with OA resolution was 71% for RYGB, 63% for LSG, and 51% for LAGB. HTN resolution was 57% for RYGB, 23% for LAGB, and 29% for LSG. HLD resolution was 71% for LSG, 67% for RYGB, and 34% for LAGB. LEE resolution was 100% for LSG (n =6), 94% for RYGB, and 68% for LAGB. RYGB produced an overall mean ORC resolution of 66%, vs 60% and 44% produced by LSG and LAGB, respectively. ORC status improvement of OA, HTN, HLD, and GERD was significantly different between surgery types (p < 0.01). Patients with OA had an average AORC score decrease, from pre-surgery to post-surgery, of 2 for RYGB, 1.6 for LSG, and 1.2 for LAGB. HTN score change was 1.8 for RYGB, 1.1 for LSG, and 0.9 for LAGB. HLD score change was 1.9 for both RYGB and LSG, and 0.9 for LAGB. GERD score change was 2.1 for RYGB, 1.6 for LAGB, and 0.7 for LSG.The overall mean change in AORC score for all comorbidities, from pre-op to post-op, was 1.7 for RYGB patients, 1.4 for LSG patients, and 1.2 for LAGB patients. There was no significant association between initial BMI and change in AORC score. The pre-op AORC scores were not significantly different between surgery types. Conclusions: Patients with OA experienced the greatest resolution and greatest AORC score improvement with RYGB. RYGB had the greatest ORC resolution for patients with OA and HTN, as well as the greatest AORC score improvement overall. LSG produced the greatest significant ORC resolution for patients with HLD and LEE. All bariatric surgery procedures had statistically significant ORC status improvements and ORC resolution for all 10 documented comorbidities.
