Transabdominal ultrasonography to reduce the burden of X-ray imaging in prophylactic pancreatic stent localization after ERCP-A prospective trial.

Transabdominal ultrasonography detects the majority of prophylactic pancreatic stents. Thereby, it helps to identify patients with an indication for endoscopy sufficiently. X-ray imaging could subsequently be omitted in about 70% of examinations, reducing the radiation exposure for the patient and the endoscopy staff.
