Background and Study Aims: Prospective data are lacking on the safety of endo scopic ultrasonography (EUS) and on patient satisfaction with the procedure. We prospectively recorded complications related to EUS in order to establish morbid ity and mortality. In addition the levels of patient satisfaction were evaluated , with regard to the tolerability of the procedure (pain, discomfort, and anxiet y levels) and the provision of information. Patients and Methods: 3324 consecuti ve patients who underwent EUS were studied with regard to complications. During the study period 300 patients were interviewed and followed up in detail as part of the evaluation of patient satisfaction. Results: Ten pa tients (0.3% ) suffered from a complication related to the EUS procedure, an d two patients died (0.06% ). There were no significant differences between the complication rates for EUS- guided fine- needle aspiration (EUS- FNA) and fo r EUS, but both fatal cases related to EUS- FNA/EUS- guided intervention. Nine of the ten patients with complications (90% ) had a diagnosis of malignancy, a nd esophageal perforation accounted for half of all complications. Although the majority of patients with nonlethal complications were managed well on conservat ive regimens, only one case, of self- limiting acute pancreatitis, could be cla ssified as a mild complication. With regard to patient tolerability, onlyminor i ncidents occurred during the EUS procedure (tracheal suction 5% , vomiting 0.3 % , aspiration 0.3% ) and no intervention was necessary. During the procedure, 80% of the patients had no or only slight pain and more than 95% experience d only slight or no anxiety, whereas more than half of the patients experienced moderate to severe discomfort. More than 90% of the patients were satisfied or very satisfied with the information provided to them before and after the EUS, and the same number of patients were ready without hesitation to undergo an addi tional EUS examination if necessary. Conclusions: EUS, EUS- FNA and EUS- guide d intervention are safe techniques, but severe and lethal complications do occur . The EUS procedures can be performed with a high level of patient satisfaction and with low levels of pain, discomfort and anxiety.
