@abcnews: A 5-month-old boy successfully underwent what doctors say was the first of its kind in-utero surgery in the United States. The groundbreaking procedure was performed at just 26 weeks of pregnancy, allowing Theo French to be born full term and leave the hospital just days after birth. Theo was diagnosed with complex gastroschisis — a condition where a baby's intestines develop outside the body — during his 20-week ultrasound, according to Dr. Sundeep Keswani, associate surgeon-in-chief at Texas Children's Hospital and principal investigator of the clinical trial.
