Repeated endoscopic ultrasound influences clinical diagnosis

The most recent publication of Gastrointestinal Endoscopy investigates the utility of a repeated endoscopic ultrasound at a tertiary-referral center.

The utility of a repeated endoscopic ultrasound by experts is not known.

Dr John DeWitt and colleagues from Indianapolis, USA defined the utility of a repeated endoscopic ultrasound for the same indication in consecutive subjects, with and without cancer.

The patients underwent an initial endoscopic ultrasound elsewhere within 6 and 12 weeks of a repeated endoscopic ultrasound at the researchers' hospital between 2000 and 2006.

A repeated endoscopic ultrasound provided a changed clinical diagnosis in 63%
Gastrointestinal Endoscopy

Of 8,936 endoscopic ultrasound examinations, 73 repeated procedures were identified, and 24 were excluded.

The 49 initial endoscopic ultrasound procedures were done in Indiana or another state, by one of 15 physicians in private practice, or at a teaching hospital.

The researchers performed an endoscopic ultrasound-guided fine-needle aspiration during an initial endoscopic ultrasound in 21 patients.

This method was not attempted in 14 patients.

The principle indication for a repeated endoscopic ultrasound in 35 patients was for an endoscopic ultrasound fine-needle aspiration after the initial tissue sampling was benign, nondiagnostic, or not done.

The researchers noted that a second endoscopic ultrasound had no clinical impact in 37% of patients.

The team found that in the remaining 63% of patients, a repeated endoscopic ultrasound provided a new or changed clinical diagnosis.

Dr DeWitt's team commented, "In this study, a repeated endoscopic ultrasound at a tertiary-referral center had a clinical impact in 63% of patients when performed by experts for a similar clinical indication."
