ANALYSIS OF THE INCIDENCE AND AGGRAVATIVES FOR CHOLELITHIASIS IN POST-OPERATIVE BARIATRIC SURGERY OF PATIENTS WITH OBSTRUCTIVE SLEEP APNEA
The high incidence of gallstones after weight reduction due to bariatric surgery is common; some studies have also brought some correlation of increased incidence of gallstones in patients with obstructive sleep apnea (OSA). However, there are still no studies that aim to correlate both characteristics together in patients and analyze their results.
To analyze whether patients undergoing bariatric surgery and patients with OSA tend to evolve in the postoperative period with cholelithiasis requiring cholecystectomy. Thus, to understand if it would not be prudent to perform prophylactic cholecystectomy so as not to have to submit the patient to another surgery in the future.
A retrospective study of patients diagnosed with obstructive sleep apnea who underwent weight reduction surgery was conducted. Patients with cholecystectomy, AHI<5 (Apnea-Hypopnea Index), or gallstones prior to weight reduction surgery were excluded from the study. All patients over 18 years of age, male and female, with obstructive sleep apnea and who were submitted, after diagnosis, to bariatric surgery, were included in the study.
After analysis, 42% of the sample presented cholelithiasis in the bariatric PO within 12 months and 30% of the sample evolved to cholecystecomia. The evaluation of polysomnographic variables of apneic patients undergoing bariatric surgery revealed a significant correlation between the presence of cholelithiasis and the minimum O2 saturation in the univariate analysis, and after multivariate evaluation, it correlated with the AHI (Severity of OSA) and percentage of REM sleep.
In the present study carried out in patients with OSA, there was a higher incidence of cholelithiasis and evolution to cholecystectomy in 12 months, respectively 42% and 30% of the sample, than reported in the literature. There was a positive correlation of the cholelithiasis outcome with AHI, Minimum saturation and percentage of REM sleep.
