GONZALEZ-PANIZO, F. et al. Impact of endoscopic ultrasonography on the management of a prospective cohort of 700 consecutive patients referred for diagnostic endoscopic ultrasonography. Rev. esp. enferm. dig. [online]. 2011, vol.103, n.2, pp.62-68. ISSN 1130-0108.

Background: endoscopic ultrasonography (EUS) is a high accuracy technique for the study of many digestive diseases. The degree of knowledge about the impact of EUS on the management of these patients is inadequate. Aim: to determine the therapeutic impact of endoscopic ultrasonography (EUS) on a prospective cohort of patients. Methods: all patients referred for EUS over a period of 2 years were prospectively evaluated in order to asses: 1. EUS provides new information not previously known; 2. theoretic impact of EUS on patient management; 3. real impact of EUS on final therapy; 4. changes in the aggressiveness of the therapeutic decision after EUS. Results: 700 patients were included. Preoperative assessment of digestive tumors was the commonest indication. EUS provided "new information" in the 89% of the patients. With regard to endoscopist opinion, these findings should alter the management in 79% of patients ("theoretic impact"). However, EUS prompted a change in the management in 67% of patients ("real impact"). Final therapy post-EUS was less aggressive in 34% of patients. Changes in therapeutic decision were associated with EUS findings, alcohol intake and age ≥ 57 years old. Conclusions: 1) EUS findings, advanced age, and alcohol intake are associated with a change in the management in 2 out of every 3 patients referred for EUS. 2) Therapeutic decision (post-EUS) is less aggressive in a third of these patients, what should represent a significant economic saving.
