In May 1962, University of Minnesota surgical chairman Owen H. Wangensteen announced in JAMA that a duodenal ulcer could be cured without an operation by swallowing a balloon and chilling the stomach to roughly minus-10 degrees Celsius — a bloodless “physiological gastrectomy” — and within two years thousands of Americans had been frozen on refrigeration machines that had never passed a single controlled trial; the gap between that announcement and the 1969 finding that a fake freeze worked exactly as well is the entire case. Gastric freezing was not a fringe quackery. It was launched by one of the most decorated academic surgeons in the United States, published in the country’s leading medical journal, and adopted at scale before anyone tested it against a placebo.
The promise rested on a plausible mechanism and a flattering measure. Wangensteen reasoned that supercooling the gastric mucosa would knock out the acid-secreting cells that drove ulcer disease, achieving by cold what surgeons then achieved by cutting out half the stomach. Early uncontrolled series were spectacular: investigators reported that on the order of 85 percent of patients had prompt relief of pain and apparent healing of ulcer craters. That surrogate — short-term symptom relief, the most placebo-responsive endpoint in all of medicine — was mistaken for cure. The acid suppression was real but transient, returning to baseline within weeks to months, and the symptom relief was, it later emerged, almost entirely the patient’s own expectation.
The reckoning came from the design that the launch had skipped. By 1964 controlled and double-blind studies were appearing, and in July 1969 a multi-institution cooperative trial led by Julian Ruffin reported in the New England Journal of Medicine that patients given a genuine gastric freeze did no better than patients given a sham freeze in which the same balloon circulated fluid that was never chilled. The treatment effect, against a proper control, was zero. Gastric freezing collapsed almost as fast as it had spread. It was never banned and never recalled; it was abandoned — and it survives in textbooks as the canonical demonstration of why a new procedure must be tested against a sham before, not after, it is sold to thousands.
In 1894, Johns Hopkins surgeon William Stewart Halsted published the results of his “complete operation” for breast cancer — an en-bloc amputation of the breast, both pectoral muscles, and the axillary lymph nodes — and reported that it had cut local recurrence from the 51–82% rates of his European contemporaries to a fraction of that; the gap between that local-control victory and the survival it never delivered is the entire case. The radical mastectomy controlled the wound bed and was mistaken, for three-quarters of a century, for a control of the disease. It was performed on the order of nine in ten American women with breast cancer well into the 1970s, left them with a hollowed chest wall, a frozen shoulder, and near-ubiquitous arm lymphedema, and — as randomized trials would eventually show — bought not one additional day of survival over far lesser surgery.
The operation did not fail because it was crude. It was, by the standards of 1894, a genuine advance: Halsted’s en-bloc dissection and his obsession with surgical technique made him one of the founders of modern American surgery, and the early survival figures — a five-year survival roughly double that of untreated women — were real. The error was theoretical. Halsted built the operation on an anatomical hypothesis: that breast cancer spread in an orderly, centrifugal, contiguous fashion outward from the breast through the lymphatics, so that cutting wider and deeper must, by geometry, cut ahead of the disease. If the theory were true, more radical surgery would mean more cures. The theory was false.
Cancer that had spread had usually spread through the bloodstream before the surgeon ever arrived, and cancer that had not spread was cured by far less. The radical mastectomy’s mutilating margins therefore changed the scar without changing the outcome. Critics — Geoffrey Keynes in England, George “Barney” Crile Jr. at the Cleveland Clinic — argued this from the 1930s and 1950s and were dismissed by a surgical establishment that treated the Halsted operation as settled doctrine.
The reckoning came from a randomized trial run by a surgeon who had once performed the operation himself. Bernard Fisher’s NSABP Protocol B-04, begun in 1971, randomized 1,665 women among radical mastectomy and two lesser procedures; B-06, begun in 1976, added lumpectomy. At every follow-up out to 25 years, survival was statistically identical. The Halsted hypothesis of contiguous spread was replaced by the systemic-disease model — that breast cancer is, at diagnosis, often already a whole-body problem the scalpel cannot outrun. The radical mastectomy was not banned; it was abandoned, retired by evidence as the textbook case of a mutilating operation sustained for 75 years by an elegant theory that happened to be wrong.
Beginning around 1916 at the New Jersey State Hospital in Trenton, its medical director Henry Andrews Cotton announced that insanity was not a disease of the mind but a hidden bacterial infection — “focal sepsis” — seeded in the teeth, tonsils, sinuses, stomach, spleen, cervix, and above all the colon, and curable by cutting those organs out; the gap between his claimed 85 percent cure rate and the documented reality, in which his colon resections killed on the order of 30 percent of patients and cured essentially none, is the entire case. Cotton extracted teeth by the tens of thousands and performed serial abdominal surgeries on institutionalized, frequently non-consenting psychiatric patients, on the theory that a “detoxified” body would yield a sound mind.
The practice was not a fringe horror tolerated in obscurity. It was celebrated. Cotton, a protégé of the most powerful American psychiatrist of the era, Adolf Meyer of Johns Hopkins, was lauded in the press as a humane reformer who had abolished mechanical restraint and replaced it with “scientific” surgical cure. His 1921 book, The Defective, Delinquent and Insane, packaged focal-sepsis theory as the frontier of psychiatry, and visiting clinicians from Britain and the United States toured Trenton to watch the operations.
The reckoning was assembled but then buried. In 1924–25 Meyer commissioned a former student, the psychiatrist Phyllis Greenacre, to audit Cotton’s results; she tracked his surgical patients and found the records chaotic, the cure claims unsupported, the recovery rate no better — in fact worse — than for unoperated patients, and the mortality catastrophic. Meyer suppressed her report rather than publish it, protecting Cotton and his own reputation, and the surgeries continued for years. Only Cotton’s retirement in 1930 and his death in May 1933 finally ended them. The focal-infection theory of insanity collapsed entirely thereafter, and “surgical bacteriology” survives now as a textbook case of how a charismatic clinician, a surrogate endpoint, and a senior authority’s cowardice can sustain a lethal, evidence-free operation on the powerless for the better part of two decades.
