America’s First Bronchoscopist
Imagine a young girl,
perhaps 7 or 8 years old, pale, weak, and emaciated. Her distraught mother
explains that weeks earlier, her daughter had swallowed lye, thinking it was
sugar. The resultant scars in her esophagus, contracting inexorably, now placed
her near death from starvation or dehydration. During much of the 19th
century most homes kept lye for making soap, and the jars did not carry danger
labels. Other home accidents included aspirated or swallowed bones, safety pins, or
coins, that might obstruct or perforate the esophagus or bronchial tree. Short
of chest surgery, risky at the time, there was little relief available.
To the rescue came the inventive Dr.
Chevalier Jackson. Born in 1863, Jackson grew up on a poor farm near Pittsburgh.
Valuing education, he worked his way through Western Pennsylvania University
(now Univ of Pittsburgh) and entered Jefferson Medical College. He took an
interest in laryngology, influenced by professors at the recently founded nose
and throat clinic. In the library of one professor, Jackson read through the
works of Sir Morrell MacKenzie, the father of laryngology in England. Determined
to study with MacKenzie, he booked the cheapest steerage passage to England, requiring him
to bring his own mattress for the assigned double-decker bunk. He stayed with
MacKenzie only briefly, however, disappointed in the design of his esophagoscope.

On return, in 1886, he opened an office in
Pittsburgh, a coal town that was so sooty that the lights were often kept on
throughout the day. Jackson’s new specialty of laryngology, fortunately, was publicized by news
bulletins about the crown prince of Germany, the son-in-law of Queen Victoria,
who had cancer of the larynx and on whom MacKenzie had consulted (see blog of
2/11/17).
Jackson was busy very soon. Enlarged,
chronically infected tonsils interfered with sleeping and breathing in those
days, and he removed them from many poor public-school children, rarely
receiving any payment. He also was adept at passing a tube through the larynx
or doing tracheotomies in children with diphtheria (where an anesthetic was
contraindicated). His inventive genius, however, found its greatest application
while dealing with foreign bodies and lye burns of the esophagus. Within four years
of arrival he had devised a new esophagoscope, with which he removed a “tooth
plate” from the esophagus of an adult and a coin from that of a child. He
reported the cases to the local medical society, only to learn of tragic
outcomes in similar instances treated by his untrained colleagues. He refused
henceforth to allow the instruments to be used without proper instruction in anatomy
and practice on anesthetized dogs.
When Jackson found he could dilate
constricted esophagi with his instruments, unexpected numbers of emaciated
children crowded his office. The numbers were so large that he initiated a
crusade to have labels placed on containers with poisonous substances. Industrial
resistance to labeling was fierce, however, and no such law was passed until
1927 – the Federal Caustic Poison Law.
Meanwhile in Austria, in 1897, Dr. Gustav
Killian, the “father of bronchoscopy”, made history by removing a piece of bone
from the bronchus of a farmer, using a rigid tube. Killian’s reports stimulated
Jackson to devise his own “bronchoscope”, and, in so doing, he introduced bronchoscopy
to America. Lighting in the distal end was adapted from cystoscopy techniques. Jackson’s
rigid scope was used almost exclusively for foreign body retrieval and biopsies.

Jackson continued to revise and perfect
new models of his scopes. He was rigorous about requiring training for their
use, and many of those he
trained went on to teaching positions elsewhere. As
his reputation spread, he was asked to demonstrate at conferences in major
cities, including Paris. He bypassed London, however; England’s severe antivivisection
laws prohibited endoscopy on dogs, even anesthetized ones.

In 1916, he accepted the Chair of Laryngology
at Jefferson Medical College in Philadelphia, and eventually held faculty
positions simultaneously at five medical schools in Philadelphia. This broke exclusivity
rules at most of the institutions, but regulations were bent to keep him
aboard. His one stumbling block was tuberculosis, each of three episodes putting him
at bedrest for months at a time. He used the idle time to
write a popular text
on endoscopy, a revised edition for use as a manual, other texts, and many
articles, 238 of which were single-authored. He was an editor of the Archives of Otolaryngology, wrote an
autobiography, and was a founder of the American College of Surgeons. In his lifetime he extracted from patients over 2000 foreign bodies, all in the Mütter Museum in Philadelphia.

autobiography, and was a founder of the American College of Surgeons. In his lifetime he extracted from patients over 2000 foreign bodies, all in the Mütter Museum in Philadelphia.
Beneath this busy and inventive exterior
lay a humane and charitable soul. Chevalier Jackson maintained that ninety
percent of his work with patients was gratis. He never patented any of his instruments, considering
it immoral to profit from medical inventions. He was a vegetarian and
attributed his unusually steady hand in bronchoscopy to his abstinence from
alcohol and tobacco. He was an accomplished artist and woodworker. He died at his farm, Sunrise Mill, near Philadelphia, at
the age of 93.
