The Making of a Surgeon

  How does a doctor recognize the point in time when he is finally a “surgeon”? As my year as chief resident(进修医生) drew to a close, I asked myself this question    36   more than one occasion.

  The answer, I concluded, was   37   . When you can say to yourself,  “There is no surgical patient I cannot treat competently, treat just   38   or better than any other surgeon” — then, and not until then, you are   39   a surgeon. I was   40    that point.

41  , for example, the emergency situations that we met almost every night. The first few months of the year I had   42   the ringing of the telephone. I knew it meant another critical decision to be   43   . Often, after I had told Walt or Larry what to do in a particular       44  , I’d have trouble getting back to sleep. I’d   45   all the facts of the case and, often, wonder   46    I had made a poor decision. More than once at two or three in the   47  , after lying awake for an hour, I’d get out of   48  , dress and drive to the hospital to see the patient myself. It was the only   49   I could find the   50   of mind I needed to relax.

  Now, in the last month of my residency,   51   was no longer a problem. Sometimes I still couldn’t be sure of my decision, but I had learned to   52   this as a constant problem for a surgeon. I knew that with my knowledge and experience, any decision I’d made was bound to be a   53    one. It was a nice feeling.

This all sounds conceited(自负的) and I guess it is —   54     a surgeon needs conceit. He needs it to encourage him in trying moments when he’s bothered by the   55   and uncertainties that are part of the practice of medicine. He has to feel that he’s as good as and probably better than any other surgeon in the world. Call it conceit — call it self-confidence; whatever it was, I had it.
