Endoscopic Ultrasound-Guided Gastroenterostomy Nationwide: Prospective Registry.

Introduction Of Endoscopic Ultrasound-Guided Gastroenterostomy Based On A Learning Protocol And Prospective Registry.

This is project of help and support for the introduction of the GASTROENTEROANASTOMOSIS technique guided by ENDOSCOPIC -ULTRASOUND (EUS-GE) in centers in Catalonia, facilitating a teacher training.

The main objective is facilitate a safe introduction of the technique, limiting technical failures, and if necessary, support in rescue techniques.

The goal of this interventional study is to assess the impact of a teaching and on live-support model in the introduction of the gastroenteroanastomosis technique, evaluating its effects in safety and the learning curve.

regarding the results in safety and learning curve of for the introduction [type of study: observational study or clinical trial] is to [learn about, test, compare etc.] in [describe participant population/health conditions]. The main question[s] it aims to answer are:

• [question 1]
