An early adopter of the "white coat" (as shown in Seligmann's c.1890 painting), Billroth was directly responsible for a number of landmarks in surgery; in 1872, he was the first to conduct an esophagectomy, removing a section of the oesophagus and joining the remaining parts together. In 1873, he performed the first laryngectomy, completely excising a larynx. He was the first surgeon to excise a rectal cancer and by 1876, he had performed 33 such operations. By 1881, Billroth had made intestinal surgery seem almost commonplace. But his most famous accomplishment is unquestionably the first successful gastrectomy for gastric cancer. On January 29, 1881, after many ill-fated attempts, Billroth performed the first successful resection for antral carcinoma on Therese Heller, who lived for almost 4 months and died of liver metastases. He accomplished this operation by closing the greater curvature side of the stomach and anatomizing the lesser curvature to the duodenum, in an operation that is still known as the Billroth I to this day.
