Editor’s Note: For 16 years, I've published weekly essays here on Blogspot, which will continue. I’ve now begun publishing my work on a new blogging platform, Substack, and I hope you’ll join me there. Please enter your email address at this link to receive my posts directly to your inbox.
Why is the medical history – the patient’s narrative – so critical? I have opined in this blog repeatedly that the medical history is paramount, much more valuable than the physical examination or the laboratory and other data. Of course, there are instances when a finding on the exam or abnormal data cracks the case, but in general, the patient’s own story is most significant most of the time.
Indeed, medical professionals, if we are not being careful,
can permit abnormal data results to lead us to a trap door which will take us
far away from where we should be. Consider
this to be a medical ‘wag the dog’ phenomenon.
Our focus should be squarely on the patient before us.
Here’s an example of a physician distraction which I have
witnessed multiple times in my career. I
am sure that I have also been lured to a trap door or two over the years.
A patient comes to her doctor complaining of stomach
aches. The doctor prescribes a
medication which is not helpful. So, an
ultrasound of the abdomen is ordered and gallstones are discovered. The patient is then referred to a surgeon who
removes the gallbladder. Although the
procedure is performed flawlessly, the patient’s pain persists afterwards. Clearly, the gallbladder was not the culprit. What happened?
Abdominal pain comes in a myriad of versions. It can appear in every region of the
abdomen. It can be a dull ache or an
intense stabbing. It can last for minutes
or hours. It can be associated with
other symptoms such as nausea or back pain.
Indeed, evaluating abdominal pain is complex and takes time to tease
through the history. This careful deliberation
is the key to the evaluation.
Gallbladder pain causes very characteristic symptoms that
physicians are familiar with. (Of
course, there are always exceptions, but let’s leave this aside for now.)
And gallstones are extremely common. The majority of individuals with gallstones
never need to have their gallbladders removed – the gallstones are simply
innocent bystanders.
Here’s the trap door.
If a doctor orders an ultrasound of the gallbladder on a patient with
abdominal pain inconsistent with gallbladder pain, and gallstones are found,
then they can be erroneously assigned the blame. This patient may soon find himself in the
operating room. Such a patient will soon
have no gallbladder but will still have abdominal pain.
There is no guarantee that an operation or a medical treatment
will be successful, even when advised by thoughtful practitioners. Physicians engage in serious due diligence,
relying upon our knowledge and experience to maximize the probability of therapeutic
success. Maximizing does not mean guaranteeing.
Although I have used the gallbladder vignette to illustrate
my point, trap door phenomena occur in all medical specialties.
Yes, I have fallen through some trap doors in my career. I do my best to listen carefully to the
patient’s story to minimize the risk that the patient and I will find ourselves
in free fall as the trap door flies open.
