it is difficult to provide an up-to-date and exhaustive list of surgeries that only one or two doctors in the world can perform. Medical advancements and training opportunities may have changed since then, and the expertise of individual surgeons can evolve over time. Furthermore, the availability of information can be limited, especially when it comes to highly specialized or rare procedures.
However, it is not uncommon for certain complex and cutting-edge surgeries to be performed by a select group of highly skilled surgeons who have extensive experience and training in their respective fields. These surgeries often involve novel techniques, high-risk situations, or extremely rare conditions.
For example, certain pioneering neurosurgeons may have the expertise to perform complex brain surgeries for rare conditions, or a handful of cardiac surgeons may specialize in intricate heart surgeries. Additionally, some surgeons might have developed unique procedures for specific medical issues, making them the only ones capable of performing such surgeries.
It's essential to remember that medical knowledge and surgical capabilities are constantly advancing, and as new doctors gain experience and training, the number of experts in specific surgeries may change. The medical community is continually striving to improve patient care and expand surgical expertise across the world.
