This applies to all surgery.

The medical system uses coarse statistics, like "did the condition go away" and "did the patient survive".

"The patient went through a devastatingly painful 9 months and slowly recovered over the course of years to work towards a small improvement in the original symptom" may be classified as a success.

And don't forget that many actors in the system are financially incentivized to recommend interventions.
