Background
Although still controversial, upper endoscopy is frequently performed before bariatric surgery. This study investigated the hypothesis that morbidly obese patients would prefer anesthesiologist-monitored sedation (AMS) compared to surgeon-monitored sedation (SMS) during preoperative endoscopy.
Methods
All patients who underwent endoscopy before their bariatric surgery were given a post-procedure survey regarding their experience with the preoperative endoscopy. The survey inquired about issues during and after the procedure. We compared patients who had AMS with IV propofol versus SMS IV narcotics and benzodiazepines.
Results
There were 100 patients (SMS = 49 and AMS = 51). Few patients complained of pain in the abdomen or throat during the procedure (AMS vs. SMS = 2 vs. 8% and 2 vs. 10%, respectively; p = NS). More patients complained about throat pain after the procedure (AMS vs. SMS = 37 vs. 45%; p = NS). More patients in the SMS group remembered the scope being placed in the mouth versus AMS (33 vs. 10%; p < 0.02). More patients remembered gagging during the procedure in the SMS group versus the AMS group, but this did not reach statistical significance (24 vs. 10%; p = 0.06). There was a trend that more patients in the AMS group felt they recovered in less than 1 h (53%) compared to the SMS group (37%; p = 0.1).
Conclusion
Patients who undergo upper endoscopy with either AMS or SMS seem to tolerate the procedure well. The preliminary benefits seen with AMS need to be further explored. AMS should be considered for patients undergoing preoperative upper endoscopy before bariatric surgery.
