In recent decades wide-ranging changes have occurred in medical school curricula. Time spent studying gross anatomy has declined amidst controversy as to how, what, and when teaching is best delivered. This reduced emphasis has led to concerns amongst clinicians that a new generation of doctors are leaving medical school with insufficient anatomical knowledge. Previous studies have established that medical students value their anatomy teaching during medical school. None have sought to establish views on the sufficiency of this teaching. We investigate the opinions of newly qualified doctors at a UK medical school and relate these opinions to career intentions and academic performance in the setting of a traditional dissection and prosection-based course. Overall nearly half of respondents believe they received insufficient anatomy teaching. A substantial proportion called for the integration of anatomy teaching throughout the medical school course. Trainees intent on pursuing a surgical career were more likely to believe anatomy teaching was insufficient than those pursuing a nonsurgical career; however, overall there was no statistical difference in relation to the mean for any individual career group. This study adds to the current debates in anatomical sciences education, indicating that overall, regardless of career intentions, new doctors perceive the need for greater emphasis on anatomical teaching.
Background and Aims
Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) or biopsy is widely practiced. Optimal sonographic visualization of the needle is critical for image guided interventions. There are several commercially available needles but no bench-top testing and direct comparison of these needles to reveal their inherent echogenicity. The aims are to provide bench-top data that can be used to guide clinical applications and to promote future device research and development.
Methods
Descriptive bench-top testing and comparison. Bench-top testing of 8 commonly used EUS-FNA needles (all of 22 gauge in size): SonoTip Pro Control (Medi-Globe); Expect Slimline (Boston Scientific); EchoTip, EchoTip Ultra, EchoTip ProCore High Definition, (Cook Medical); ClearView (Conmed); EZ Shot2 (Olympus); BNX (Beacon Endoscopic); and 2 new prototype needles that are coated by echogenic polymers by Medi-Globe. Blinded evaluation of standardized and unedited videos by 43 EUS endoscopists and 17 radiologists specialized in gastrointestinal ultrasound examination that is unfamiliar with EUS needle devices.
Results
There was no significant difference in the ratings and rankings of these needles between endosonographers and radiologists. Overall, one prototype needle was rated as the best, ranking 10% to 40% higher than all other needles (p<0.01). Among the commercially available needles, the EchoTip Ultra needle and the ClearView needle were top choices. The EZ Shot 2 needle was ranked statistically lower than other needles (30%–75% worse, p<0.001).
Conclusions
All FNA needles have their inherent and different echogenicity, and these differences are similarly recognized by EUS endoscopists and radiologists. Needles with polymeric coating from the entire shaft to the needle tip may offer better echogenicity.
Digital rectal examination is frequently performed by the most inexperienced doctor and may not be verified by a more senior colleague. More training and supervision of junior doctors are required both prior to qualification and during the early stages of their medical career.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
