His surgeon used the model in preparation for the surgery and the 3-D image during surgery. The surgery was successful and he is recovering nicely. "It remains to be seen whether other bowel surgeons will want to incorporate 3-D imaging into their operating rooms. Ramamoorthy said she is enthusiastic about the idea. She plans to use 3-D imaging with more of her patients in the hopes of standardizing this approach."
