Patients presenting to two tertiary referral centers for EUS evaluation were prospectively enrolled. The patients completed a survey regarding any GI symptoms. The patient's age, gender and indication for the EUS were recorded. At the time of the procedure, the endoscopist completed a questionnaire regarding the level of difficulty of the procedure, any luminal abnormality noted during EGD or EUS, and the timing of the two procedures. Information regarding biopsies taken, any complications, and recommendations made based on the EGD portion of the study were also recorded.
