Dr. Gagliano Jr. is the best in his field. You can relax that he will do the best job possible. My husbands reattachment of the colon was a more challenging task because he had emergency surgery 10 months earlier and they removed 11 inches of intestines. So Dr. Gagliano had to repair what some other surgeons work had done. Dr. Gagliano is the best.
