A New York City hospital that evacuated hundreds of patients after losing power during Superstorm Sandy has partially reopened.

Officials at NYU Langone Medical Center say about 55 surgeries were being performed Thursday. The Manhattan hospital also has brought back a number of other services, including medical and surgical intensive care.

The emergency room remains shuttered after taking a severe hit when water surged out of the East River and flooded the facility. A temporary urgent care center should be running in a few weeks. The maternity unit, pediatrics and other services are due reopen Jan. 14.

Some 320 patients had to be moved after NYU Langone lost generator power in the storm. The hospital suffered about $1 billion in damage.

Some outpatient facilities have been open since early November.
