Bariatric Surgery for Treatment of Sleep Apnea Syndrome in 15 morbidly obese patients: long-term results

To evaluate the long-term outcomes of bariatric surgery with respect to respiratory disturbance index (RDI) in sleep apnea syndrome (SAS).

Design

Case series with long-term follow-up (1 to 12 years).
Setting was a private clinic in an academic tertiary referral center. Patients included 15 morbidly obese patients (10 men, 5 women) who were referred for the treatment of severe SAS.

Intervention

For all 15 patients who presented with severe SAS, nasal positive airway pressure breathing was either not available or was not tolerated by the patient; therefore, bariatric surgery was performed as a means of treatment for SAS.

Main Outcome Measures

RDIs and minimum oxygen saturation were measured both preoperatively and postoperatively (1 to 12 years after surgery).

Results

Weight loss ranged from 60 to 220 pounds (27 to 100 kg). RDI decreased by at least 55% in each patient, and all patients with tracheostomies (8 of 15) had their tracheostomy tubes removed. Average RDI preoperatively was 96.9 and average RDI postoperatively was 11.3. Results were similar for all 15 patients in that minimum oxygen saturation increased during sleep from an average preoperative minimum oxygen saturation of 58.7% to an average postoperative minimum oxygen saturation of 85.2%.

Conclusion

Bariatric surgery as a means of treating SAS in the morbidly obese provides effective long-term reduction in RDI. Bariatric surgery also significantly improves minimum oxygen saturation in morbidly obese patients with SAS. Biliopancreatic bypass is more effective in reducing RDI to normal values than vertical banded gastroplasty.

Laparoscopic or open bariatric surgery, such as gastric banding or bypass is not an easy solution to morbid obesity and weight loss. It is a serious surgical procedure, involving health risks. To produce lasting weight loss it requires a long-term patient commitment to eating a healthy diet and following a regular program of physical exercise. Life-long use of nutritional supplements may also be necessary. So, before deciding, discuss your options fully with your doctor. © 2003-2017 Bariatric-Surgery.Info - Terms - Contact - Information - Resources
