ABSTRACT

Introduction. In the last decades, the endoscopy has have a great develop allowing the development of an ultrathin endoscope that allow us perform an upper gastrointestinal endoscopy without use of anesthesia. Objective. Compare transnasal vs. transoral esophagogastroduodenoscopy in order to the comfort and security in unsedated patients. Patients and methods. We included all patients who were sent to endoscopy unit of Hospital Juarez de Mexico for a diagnostic upper gastrointestinal endoscopy during January 2008-October 2009. Statistical analysis. For descriptive variables we used frequencies and percentages. For comparative analysis we used χ². Results. We obtained a total of 156 patients, 101 women and 55 men, with a range of age of 16-90, median age of 44 years. For quantitative variables we used T test with a P significant ‹ 0.05, for cardiac frequency, and χ² for qualitative variables with a P significant ‹ 0.05 for cough, epistaxis, nausea and comfort. Conclusion. Transnasal endoscopy provides the same image quality as conventional endoscopy, is safe and comfortable in unsedated patients. However, it does not allows therapeutic procedures.
