Emergency Ultrasound of the Gall Bladder: Comparison of a Concentrated Elective Experience vs. Longitudinal Exposure During Residency
The Journal of Emergency Medicine, 05/03/2012
Jang TB et al. – Physicians who participated in a 2–week, semi–structured emergency ultrasound (EUS) elective demonstrated EUS accuracy for biliary disease that was comparable with those who performed the same number of examinations over a longer period of time.
This was a secondary analysis of a previously reported prospective study of EUS for biliary disease.
The 21st-40th examinations were compared between those who participated in an EUS elective and those who did not.
The gold standard was ultrasound done by the Department of Radiology.
Mean time to complete 40 EUS examinations for biliary disease was 14months for those participating in an EUS elective compared with 29 months for those who did not.
One hundred and ninety-one examinations (49%) were done by 19 operators who did not participate in an EUS elective and 202 examinations (51%) were done by 23 operators who completed an EUS elective.
There was no statistical difference between the two groups with regard to detecting the presence of gall stones, gall bladder wall thickening, pericholecystic free fluid, ductal dilation, or sludge.
