HGMs of the upper esophagus are not infrequent, although generally small and asymptomatic. In cases of large HGMs, acid secretion capacity may cause upper esophageal disorders.

Questionnaires on satisfaction or quality perceived by patients allow the most frequent causes for dissatisfaction to be identified. The main problems patients encountered were waiting time until the appointment and explanations.

Background: there has not been a validated questionnaire available in Spanish to evaluate patient satisfaction with gastrointestinal endoscopy. Our aim was to evaluate the external validity and internal consistency of the Spanish version of a questionnaire on patient satisfaction with gastrointestinal endoscopy elaborated by the American Society for Gastrointestinal Endoscopy. Design: prospective questionnaire validation study. Patients and methods: a total of 485 consecutive patients referred to two different hospitals for endoscopy were interviewed by telephone. Internal consistency was studied using Cronbach's alfa test and corrected item-total correlations (CITC). External validity was determined using a mailed questionnaire completed by 185 patients-correlations between telephone and postal responses were calculated, as well as the correlation with the total score obtained. Results: Cronbach´s alfa was 0.82 and mean CITC was 0.59. Weighted kappa values for the same questionnaire items performed by telephone or mail varied between 0.51 and 0.81. Total score correlation was 0.78. Internal consistency and external validity were not affected by differences in the administration of the questionnaire (mail or by telephone), different interviewers, type of endoscopy, or source of patients. Conclusions: the Spanish version of the ASGE questionnaire on satisfaction with endoscopy is valid, reliable, and reproducible.
