Apollo Endosurgery Announces Presentation of Mortality and Inpatient Costs of Revisional Bariatric Surgery

The presentation reported a retrospective cohort analysis of a Nationwide Inpatient Sample (NIS) discharge data on adult patients who had a principle diagnosis indicating a revisional bariatric surgery. The primary outcome reviewed in the study was mortality following revisional surgery. Secondary outcomes were cost, length of hospital and intensive care stay.

Key data reported from 14,280 patients who underwent inpatient revisional bariatric surgeries include:

• Post-operative inpatient mortality was 2.1% (290 patients)
• Length of hospital stay was 5.4 days
• Mean cost per patient was $65,836
• 3.3% of patients required intensive care stay, and of those, there was a 25% mortality rate

“Revisional bariatric surgeries increased from 6% of all bariatric procedures in 2011 to 13% in 2015. Previously published data based solely on a self-reported registry suggest a mortality rate of approximately 0.12 – 0.21%. In our study, which was based on inpatient billing data, the early post-operative inpatient mortality rate for revisional bariatric surgery was 2.1% - significantly higher than previously reported,” said Violeta B. Popov MD, Ph.D., lead author of the study and Assistant Professor, Department of Medicine at NYU Langone Health. “Alternatively, evidence demonstrates an endoscopic approach to bariatric surgical revisions is a safe, effective and clinically meaningful option for patients that should be considered before surgery.”

“Revision of bariatric surgery has increased, and we expect this will continue. An endoscopic approach to bariatric revision based on flexible endoscopic suturing using OverStitch™ demonstrates clinically meaningful benefits, at a much lower cost, and without the increased risks of surgery,” said Todd Newton, CEO of Apollo Endosurgery.
