Surgery is a common theme on Lost, and has been utilized both on the Island and off. Most of the surgeries seen on the show were conducted by Jack, Juliet, or Christian, three characters who are best known as doctors. Also, most surgeries are used to significantly advance the plot (i.e. Jack holding Ben hostage to allow Kate and Sawyer to escape).
