Background/Aims: Although the diagnostic and therapeutic value of double balloon endoscopy (DBE) have been investigated in many studies, the subjective tolerability to DBE has not been assessed. We aimed to evaluate the tolerability to a DBE. Methods: Patients who underwent DBE in Asan Medical Center between March 2005 to March 2007 were eligible in this study. For the comparison of tolerability to DBE with that to EGD and colonoscopy, those who had not undergone EGD nor colonoscopy were excluded. A total of 52 patients were included in this study. Because 7 patients underwent both antegrade and retrograde DBE approach, the total number of DBE procedures analyzed in this study was 59. All procedures were performed under conscious sedation. Tolerability to DBE, EGD, and colonoscopy was assessed through an interview using a standardized questionnaire. Results: A total of 36 patients underwent both antegrade DBE and EGD under conscious sedation. The level of abdominal pain during procedures, the level of post-procedural abdominal discomfort and the proportion of patients with persistent abdominal discomfort till the next morning were higher in antegrade DBE. However, when analyzed in 16 patients who had good quality of sedation, the differences in the level of abdominal pain during procedures and the persistent abdominal discomfort till the next morning disappeared. A total of 23 patients underwent both retrograde DBE and colonoscopy under conscious sedation. Tolerability parameters were not different between retrograde DBE and colonoscopy. Serious complications including hemodynamic instability did not occur during all procedures. Conclusions: Patients tolerate DBE well. DBE can be performed as comfortably as EGD and colonoscopy if the quality of sedation is good enough.
