UNIT 4.4/4.4G
ENDOCRINE
SURGERY
NOTE: Endocrine
surgery differs from many other areas of surgery in that there are not simple
"junior level" cases and more complicated "senior level"
cases. Most endocrine surgery
cases are considered "senior level," primarily because the cases are
infrequent and it takes three or four years before a resident has seen enough
cases to be familiar with the variety of clinical presentations. Within
endocrine surgery there are diseases which are relatively common and others
which, although they be interesting, are exceptionally rare.
Detailed knowledge of those latter diseases should not
be the province of the resident who should focus only on the more common
entities.
