Sutures during the surgery scene are too far apart. The wound would have also been thoroughly irrigated prior to suturing. As a result, there would have not been a foreign body present after wound closure had begun.
At 17:44, there is an Establishment Shot outside the Hospital with a bunch of extras walking into, walking out of, and standing around the Hospital. At 30:46, in an obvious recycled scene, there is a second Establishment Shot with all the same extras doing all the same motions.
