Today more than 48 million surgeries are performed in the United States alone, and the sheer volume makes the operating room feel almost ordinary. With 28 million of those being outpatient procedures—meaning patients stroll out the same day without an overnight stay—the knife has become a familiar tool. Yet beneath that familiar veneer lie stories that are anything but ordinary. In this top 10 bloody tour we’ll peel back the curtain on the shocking, fascinating, and sometimes downright macabre beginnings of the surgeries we now take for granted.
10 Year-Old Boy’s Appendix in 1735
Appendicitis—when the tiny appendix swells, inflames, and fills with pus—affects roughly 8% of the population at some point. If the inflamed organ bursts, bacteria and debris spill into the abdominal cavity, a scenario that, left untreated, almost certainly spells death.
The condition has been noted for millennia. As early as A.D. 130, Galen’s anatomical treatises mentioned a painful abdominal ailment, and physicians continued to reference it for centuries. Yet the appendix itself remained a mystery until the late 1400s, and its link to the painful syndrome was only cemented by German surgeon Lorenz Heister in 1711. For countless generations, that 8% lived (and often died) without ever understanding why they suffered.
Understanding the cause, however, mattered less than finding a cure. In 1735, English surgeon Claudius Amyand performed the world’s first recorded appendectomy on an 11‑year‑old boy whose appendix had been pierced by a swallowed pin. The operation was a landmark, and the boy also turned out to have a rare type of inguinal hernia that would later bear Amyand’s name.
That single case delivered two firsts at once: the inaugural appendectomy and the discovery of the Amyand hernia. It would be another 24 years before surgeons began using the procedure routinely to treat appendicitis. Today, roughly 300,000 appendectomies are carried out each year in the United States, sparing millions from the pain and peril of a ruptured appendix.
9 First Brain Surgery: Trepanation Performed On Our Distant Ancestors
The brain sits beneath a delicate covering called the meninges, which is riddled with blood vessels. When a head injury tears these vessels, blood can pool between the brain and skull, creating a subdural hematoma. Pressure builds, threatening to crush the brain and cause death unless relieved.
Enter the burr hole: a small opening drilled into the skull to let the trapped blood escape—a primitive pressure valve. Though it sounds modern, trepanation dates back 5,000 years. Archaeologists have found that 5‑10% of Neolithic skulls bear evidence of such holes, indicating that ancient peoples performed this life‑saving procedure long before anesthesia or antiseptics existed.
But not all trepanations were medical. In southern Russia, twelve skulls uncovered within a 31‑mile radius all featured burr holes in the exact same spot—the obelion, a region near the back of the skull where a ponytail might sit. None of the skulls showed signs of trauma, suggesting the holes were ritualistic rather than therapeutic.
Anthropologist Elena Batieva posits that these individuals were perfectly healthy when their skulls were pierced, likely as part of a dangerous rite. Several of the skulls never healed, indicating the ritual may have been fatal for some. The true purpose of these ceremonial trepanations remains a mystery, locked away in bone.
8 First Biopsy: A Hollow Needle in A.D. 1000
Although the word “biopsy” was only coined in 1879 by Ernest Besnier, the practice predates the term by centuries. The earliest known biopsy was performed by the renowned court physician Abu al‑Qasim Khalaf ibn al‑Abbas Al‑Zahrawi—also known as Albucasis—who lived between 936 and 1013 A.D. He slipped a long needle into a patient’s thyroid gland, extracting tissue to diagnose a condition he called “Elephant of the throat,” a technique eerily similar to today’s fine‑needle aspiration.
Al‑Zahrawi’s medical manuscripts also catalogued the instruments he used, describing hollow needles that served as precursors to the modern tools employed for biopsies, injections, and blood draws. His detailed illustrations reveal a sophisticated understanding of minimally invasive sampling long before the modern era.
7 First Successful Cesarean: Mother and Child Saved In 1794
For most of history, a cesarean section was a last‑ditch effort performed only when the mother was already dead or dying. The operation almost guaranteed the mother’s death, though it could sometimes rescue the infant. Mythology even reflects this grim reality—Greek legend tells of Asclepius being delivered from his mother’s dead womb.
The holy grail of obstetrics was a cesarean that saved both mother and child. While medieval accounts claim successes, the first indisputable case occurred in America in 1794. Elizabeth Bennett, in the throes of a perilous labor, begged her physicians to perform a cesarean. They refused, deeming it fatal for her. Her husband, Dr. Jessie Bennett, stepped in and performed the operation himself, miraculously delivering a healthy baby and preserving his wife’s life.
That groundbreaking event paved the way for modern obstetrics. Today, roughly one‑third of births in the United States are delivered via cesarean section, a testament to how far the procedure has come from its deadly origins.
6 First Cataract Surgery: Ancient “Couching” Technique
Cataracts—cloudy protein deposits that fog the eye’s lens—have plagued humanity since antiquity. One of the earliest visual records is an Egyptian statue of the priest Ka‑aper (c. 2457‑2467 B.C.) depicting a heavily clouded eye.
Ancient surgeons devised a bold remedy: a copper needle or lancet was inserted into the eye to dislodge the cataract, pushing it deeper into the vitreous cavity. This method, known as “couching,” didn’t remove the lens opacity but often restored enough vision for the patient to function. The practice appears in the Code of Hammurabi, where a law warned that a physician who caused loss of an eye would have his hands cut off.
Couching persisted for millennia until 1748, when French physician Jacques Daviel performed the first true cataract extraction, removing the cloudy lens entirely. This marked a turning point toward the sophisticated eye surgeries we enjoy today.
10 People Who Woke Up During Surgery
5 First Cholecystectomy: Removal of the Gallbladder in 1882
The gallbladder, a modest pouch beneath the liver, stores bile to aid fat digestion. When gallstones, infection, or rare cancers strike, patients suffer painful attacks. In the 1880s, German physician Carl Johann August Langenbuch, then only 27, routinely opened patients’ abdomens, incised the gallbladder, and cleared its contents—a painful, temporary fix.
Unwilling to settle for short‑lived relief, Langenbuch envisioned a bold solution: total removal of the gallbladder. Skeptics feared the procedure could be lethal. After practicing on cadavers, Langenbuch performed the first successful cholecystectomy on a living patient in 1882, ending a 17‑year battle with gallstones. The patient recovered quickly with minimal side effects.
By 1897, over a hundred cholecystectomies had been performed, and today the operation ranks as the second most common surgical procedure worldwide.
4 First Coronary Artery Bypass Graft: Performed in 1960
Coronary artery bypass grafting (CABG) reroutes blood around clogged heart arteries using a vessel taken from elsewhere in the body. The road to this lifesaving surgery was paved by a series of incremental breakthroughs. In 1910, Alexis Carrel explored coronary circulation in dogs, laying foundational knowledge. Claude Beck (1935) experimented with substances in the pericardium, while Arthur Vineberg (1946) pioneered a bypass by linking the left internal thoracic artery to the heart wall. Charles Bailey’s 1956 coronary endarterectomy stripped blockages directly.
The pivotal moment arrived inadvertently when Mason Sones mistakenly injected contrast dye into a patient’s right coronary artery, discovering the technique for coronary angiography—allowing surgeons to see arteries in real time rather than operating blind.
All these advances culminated in 1960 when a team led by Robert Goetz performed the first successful CABG. Although the patient died 13 months later, autopsy revealed the graft remained intact, confirming the procedure’s efficacy and opening the door to modern cardiac surgery.
3 First Tonsillectomy: Common Even in 1000 B.C.
A tonsillectomy removes the two lymphoid tissues at the back of the throat, often the first surgical experience for many children plagued by recurrent sore throats.
The practice stretches back to antiquity. Ancient Hindu texts from around 1000 B.C. describe tonsil removal, but the most detailed early account comes from Roman physician Aulus Cornelius Celsus (A.D. 40). He recorded that surgeons would grasp the entire tonsil by hand and extract it in one swift motion—a technique that persisted well into the twentieth century.
2 First Orthopaedic Surgery: A 3,000‑Year‑Old Knee Pin
For decades, a mummy housed at the Rosicrucian Museum in California was thought to be an ordinary ancient Egyptian burial dating from the 11th‑16th centuries B.C. In 1995, researchers X‑rayed six of the museum’s mummies and discovered a startling anomaly in one: a nine‑inch metal pin lodged in its left knee.
Initially, project leader Professor Griggs assumed the pin was a modern addition, perhaps an artifact of recent restoration. However, further examination revealed a resin resembling bone cement surrounding the pin, as well as ancient fat and textiles, confirming the pin was part of a genuine 2,600‑year‑old surgical procedure.
Dr. Richard Jackson, a physician involved in the study, marveled at the biomechanical savvy of the ancient surgeon, noting the pin’s design mirrors modern rigid fixation methods. The operation was not intended to improve the individual’s earthly life; instead, it was performed post‑mortem to ensure the deceased’s body remained functional for the afterlife—a testament to Egyptian reverence for bodily integrity beyond death.
1 First Plastic Surgery: An Ancient Indian Nose Job
Contrary to popular belief, “plastic” surgery does not refer to synthetic polymers but derives from the Greek word plastikos, meaning “to give form.” The earliest recorded cosmetic procedures predate modern materials by over a millennium. The 6th‑century A.D. Indian medical treatise, the Sushruta Samhita, details a sophisticated nasal reconstruction technique.
The text instructs surgeons to measure the missing nose with a leaf, harvest a cheek skin flap attached by a small pedicle, and graft it onto the nasal stump after freshening the recipient site. The reconstructed nose is then supported with castor‑oil plant tubes, powdered herbal dressings, and continuous sesame‑oil applications. Once the graft heals, adjustments can be made to achieve the desired length.
The Sushruta Samhita catalogs 1,120 illnesses, 121 instruments, and 300 procedures, illustrating the breadth of ancient Indian surgical knowledge. This rhinoplasty method remained undocumented in the West until 1794, when a London publication described a similar technique used to rebuild the nose of a mutilated cart driver, marking the first Western encounter with Indian plastic surgery.
