Emergency Ultrasound of the Gall Bladder: Comparison of a Concentrated Elective Experience vs. Longitudinal Exposure During Residency
The Journal of Emergency Medicine,

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.

Methods
  • 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.

Results
  • 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.
