Abstract

Background: Minimizing bariatric surgery care costs is important since more than 250,000 patients undergo bariatric surgery annually in the United States. The study objective was to compare perioperative costs for the two most common bariatric procedures: laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). In addition, we sought to identify predictors of high-cost perioperative care. Methods: Adult patients who underwent LSG or LRYGB from 2012 to 2017 were identified using our institutional bariatric surgery database. Perioperative costs, defined as costs incurred from the time of entering the preoperative unit until exiting the postanesthesia care unit, were obtained through billing data. Median perioperative cost components of LSG and LRYGB were compared using Mann-Whitney tests. Multivariable logistic regression was performed to investigate patient-level predictors of high-cost care, defined as the top tercile of perioperative costs. Results: We included 546 bariatric surgery patients with a mean age and body mass index (BMI) of 49.7 years and 45.9 kg/m2, respectively. There were no significant differences in median perioperative costs between LSG and LRYGB ($14,942 versus $15,016; P = .80). Stapler use was the largest cost contributor for both procedures, accounting for 27.7% and 29.2% of costs for LSG and LRYGB, respectively. In multivariable analyses, preoperative patient characteristics, including BMI, were not associated with high-cost perioperative care. Conclusions: Perioperative costs for LSG and LRYGB were similar in our single institution study. Reducing costs outside of the operating room, including those related to ED visits and complications, may be more impactful than focusing on cost reduction directly related to perioperative care.
