Several examples of successfully separated conjoined twins born during this decade (with their separation dates, if known) include Lisa and Elisa Hansen of Utah (1979), Chun-yi and Chun-jen Chang of China (conjoined from the waist down with three legs) (1977), Andrew and Grant Priestly of Australia, and Clara and Altagracia Rodriguez (1974). The September, 1974 separation of the Rodriguez Twins from the Dominican Republic was performed at The Children's Hospital in Philadelphia by Dr. Everett C. Koop (later the Surgeon General of the United States and a veteran of several separation surgeries who was quoted in The Washington Post in 1988 as saying "I am willing to take any reasonable risk to separate Siamese twins because of the grotesque future they face"). A team of 23 doctors performed the surgery on the 13-month-old ischiopagus girls (they shared one liver and parts of the same colon). Both babies survive the separation, but Alta dies at age three after choking on a bean. Clara lives a healthy life in the Dominican Republic.
