A Moment in History

William S. Halsted, MD

William S. Halsted, MD
(1852 – 1922)

American anatomist, teacher, and surgeon, William Stewart Halsted was born in New York City, USA to a wealthy family of English origin. His father was involved in charitable work and Governor and trustee to a city hospital. Not a brilliant student initially, Halsted took an undergraduate in Liberal Arts in Yale, CT., after which he entered the Medical College of Physicians at the Columbia College, where he excelled.

As a second-year medical student Halsted applied and obtained a position in surgery at a local hospital. In here he learned about Lister’s antiseptic technique and became an adamant proponent of it to reduce infection. In 1877 Halsted obtained his MD. After a short time as House Physician at the New York Hospital, Halsted traveled to Europe to further his education studying for two years at the Universities of Vienna, Leipzig, and W?rzburg.

Besides being at the forefront of surgical and antiseptic techniques (introducing the use of rubber gloves in surgery), Halsted was extremely concerned with the way medical students were taught in the US. He pioneered bedside clinical round discussions with the medical students after two years of basic sciences studies. Halsted developed the idea of a patient chart; he also developed the residency program for medical students in use today.

Halsted is probably the most influential researcher and surgeon at the turn of the century. He dedicated time to the study of intestinal anastomoses and the use of silk as a suture material. His experimental work in 1887 proved that the inclusion of the submucosa layer in an anastomosis was mandatory, as well that a single layered anastomosis was enough to attain closure. Perhaps Halsted’s most important contribution was the application and use of the scientific method to surgical questions. Halsted’s principles, also known as  "Halsted's Rules of Surgery", set the standards used today in surgical suturing and surgical stapling.

He also pioneered the development and surgical techniques for radical mastectomy as a treatment for breast cancer.

As a side effect of this studied in anesthesia and the use of cocaine for anesthesia, Halsted became addicted to this substance, a problem that followed him through the years. Without impairing his capacity as a researcher and a surgeon, Halsted eventually recovered. He died in Baltimore in 1922 as a complication to surgery.

A public anatomy at the University of St. Louis

The terms “anatomy” and “dissection” are synonymous. In the days of Andreas Vesalius, the dissection of a corpse was a public event, where medical students would attend, as well as the paying public.

This event would go on for days as the dissector would explain the anatomy racing against time, as there were no means of body preservation.

Through the centuries after the public anatomies of the 1500’s, the dissection of donated bodies has been continued in the anatomy departments of medical schools helping medical students and surgeons prepare for the challenges of the practice of medicine and surgery.

A public anatomy was one of the events of the interdisciplinary symposium "Vesalius and the Invention of the Modern Body" hosted by the St. Louis University and the Washington University February 26-28, 2015. To my knowledge, a public anatomy has not been done in centuries (I may be wrong).

Some of the objectives were to demonstrate that Andrea Vesalius' description of the anatomy of the brain, its ventricular system, and the cranial nerves was logical, followed a process, and that  the Fabrica, in its seventh book can be used as a dissector. The presentation was entitled “A Fabrica-guided Neo-Vesalian Public Dissection of the Brain Ventricular System 500 Years Later at St. Louis University” by Dr. Salomon Segal.

The dissection used excerpts and images from the Fabrica, as well as an advanced HD 3D camera, showing the brain and its structures with amazing clarity. The accompanying photo of the event is not well focused because of the light conditions, but shows the setup for the presentation.

This was an extremely professional presentation and although not completely “public” per se, the variety of attendees had a great feedback on the event. Proper attention to the care and respect towards the specimens and the anonymity of the donors was maintained at all times. I consider myself honored to have been a witness and a participant to this extraordinary event. Dr. Miranda.
