1Department of Family Medicine, Michigan State University, East Lansing, USA.
Objective:
To evaluate the performance and findings of diagnostic esophagogastroduodenoscopy (EGD) procedures in a primary care office setting, comparing two nonintravenous methods of sedation and anesthesia.
Design:
A consecutive case series of patients with appropriate indications referred over a 13-month period for the EGD procedure was studied. Procedure outcomes and patient acceptance were evaluated following the procedure.
Setting:
Patients were referred from community primary care physician offices to another community private office.
Patients:
Medically stable adult patients with indications for nonemergent EGD were referred for evaluation.
Intervention:
Esophagogastroduodenoscopy was performed in an office setting using small-caliber (7.9-mm or 9.0-mm) fiberoptic endoscopes. Patients were given either diazepam orally and ketorolac tromethamine intramuscularly or triazolam orally and butorphanol tartrate spray intranasally as sedation prior to the procedure.
Main Outcome Measures:
Clinical findings observed, histopathologic results, complications, oxygen desaturation, cardiac dysrhythmias, and length of procedures were recorded. Patients reported pain and satisfaction scores on a linear numeric scale following the procedure.
Results:
No major complications were noted in this study population. Seventy-three percent (52/71) of all patients rated their discomfort during the office-based EGD procedure as mild, with 49% (35/71) giving the lowest possible pain score rating. Ninety-six percent (68/71) of all patients rated their satisfaction with the procedure as high, with 65% (46/71) reporting the highest possible level of satisfaction. The study did not demonstrate a significant difference in patient comfort or satisfaction between the two methods of nonintravenous sedation.
Conclusions:
Two alternative methods to intravenous sedation and anesthesia appear to create adequate comfort and satisfaction for patients undergoing EGD and merit future study and consideration.
