Rationale:
Bariatric surgery is a highly effective and sustainable treatment against obesity.
Recently there has been a trend towards Same-Day Discharge (SDD) bariatric surgery. SDD
bariatric surgery has proven to be safe, when proper discharge criteria are used.
However, there is no consensus or guideline for discharge criteria for SDD bariatric
surgery. In particular, discharge criteria for patients with obstructive sleep apnea
(OSA) diverge between hospitals. In some, but not all hospitals, having (untreated) OSA
is a contra-indication for SDD bariatric surgery.
In Rijnstate hospital, bariatric patients are not routinely tested for OSA
preoperatively, meaning that they potentially have undiagnosed OSA. Having potentially
undiagnosed OSA, is not a contra-indication for SDD bariatric surgery in Rijnstate
hospital. Hospitals could be hesitant for SDD bariatric surgery in patients with OSA,
because it is known that the apnea hypopnea index (AHI) increases postoperatively. In a
population without obesity, the highest postoperative AHI was found during the third
postoperative night. During this third postoperative night, patients with a normal
postoperative course will already sleep at home, both after inpatient and SDD bariatric
surgery. This raises the question whether having (untreated) OSA should be a
contra-indication for SDD bariatric surgery. However, it is unknown if the same
postoperative changes in AHI and sleep architecture occur in patients undergoing
bariatric surgery. Objective: The primary objective of this study is to assess
postoperative Apnea-Hypopnea Index (AHI) changes during the first and third night after
Same-Day Discharge bariatric surgery in patients with potentially untreated OSA. The
secondary objective of this study is to compare postoperative AHI changes between
patients with a pre-operative AHI of 0-14 or ≥15. The tertiary objective of this study is
to describe and compare pre- and postoperative sleep architecture.
Study design:
This is a prospective observational study. AHI and sleep architecture will be assessed
and compared before and after Same-Day discharge (SDD) bariatric surgery during the first
and third postoperative night with Home Sleep Apnea Tests.
Study population: Patients scheduled for primary SDD bariatric surgery without treated
OSA
Main study parameters/endpoints: Primary endpoint is AHI. Secondary and tertiary
endpoints are 30 days complications rate, and parameters for sleep architecture and sleep
related breathing.
