Abstract

Background

The Edmonton Obesity Staging System (EOSS) is a staging system describing comorbidities and functional limitations associated with obesity, thus facilitating the prioritization of patients for bariatric surgery. Our objective was to elucidate any associations of EOSS scores with major complications after laparoscopic Roux-en-Y gastric bypass (LRYGB).

Methods

A retrospective chart review examined patients who received primary LRYGB from 2009 to 2015 at a single center. Collected data included patient comorbidities, preoperative EOSS stage, body mass index (BMI), age, percent excess weight loss, and 1-year major complications. Major complications were defined by a Clavien–Dindo classification ≥ IIIa.

Results

378 patients (81.7% female) receiving primary LRYGB were reviewed with the following EOSS stages: 0 (3.7%), 1 (10.8%), 2 (78.6%), 3 (6.9%), and 4 (0.0%). The mean preoperative BMI was 45.9 (SD 6.3) kg/m2. The overall major complication rate was 9.3%. Major complication rates for EOSS stages 0, 1, 2, and 3 were 7.1%, 4.9%, 8.8%, and 23.1%, respectively. Follow-up rates at 12 months were 76.6% with a mean overall follow-up of 10.9 (2.1) months. Multivariable analysis showed that patients undergoing LRYGB with an EOSS of 3 were more likely to experience major complications (OR 2.94; CI 1.04 to 8.35, p = 0.043).

Conclusion

Our findings suggest that undergoing LRYGB with EOSS stage 3 has increased odds of major complications. As such, the EOSS demonstrates utility in identifying bariatric surgery candidates at risk of major postoperative morbidity. Further studies are required to assess the applicability of the EOSS for patients undergoing other forms of bariatric surgery.
