State of endoscopic ultrasonography in Spain in 2017

Abstract

Aim: To understand the current state of endoscopic ultrasonography (EUS) in Spain.

Methods: Descriptive analysis from a national survey with 11 questions: 10 related to technique and 1 to the training and experience of the endoscopists.

Results: Sixty endoscopists from 48 of the 97 (49.5%) hospitals that perform EUS in Spain responded to the survey. A total of 28,678 procedures (20,311 diagnostic, 7,446 with puncture and 921 therapeutic) were recorded over the course of one year. Approximately 64% of the hospitals perform between 300 and 999 tests per year. All have radial and sectorial echoendoscopes, with a median of 2 (2-8) scopes. For cytological diagnosis, the 22-gauge needle is the most commonly used (98%) and, for histological diagnosis, the Procore (72%). The study of the pancreas and bile duct is the most common indication for diagnostic EUS (60%), followed by the staging of digestive tract neoplasms (20%). Approximately 72% of the hospitals perform on-site cytopathology evaluations and sedation is administered in equal parts by both endoscopists and anaesthetists. In terms of experience, 45% of echoendoscopists perform fewer than 300 annual exams and the median training duration is 6months (0.5-36).

Conclusions: EUS is adequately implemented in Spain and good equipment is available. However, it is necessary to establish a standardised EUS training program since the one undertaken by many echoendoscopists could prove insufficient according to the standards established by Scientific Societies.
