The state Health Department has approved an application from Erie County Medical Center to open two new operating suites, prepare two additional “shelled” operating rooms for future expansion and add related recovery and surgical services space, the hospital announced Wednesday.

The operating room expansion will go in the building that houses outpatient dialysis for the new Center for Excellence in Transplantation and Kidney Care.

The new suites are needed because of a 10 percent increase in ECMC’s surgical volume during the past two years, officials said.

The increased volume is related to an increase in emergency room cases, consolidation of Great Lakes Health’s transplantation programs for kidney and pancreas on the ECMC campus, and an increase in surgical cases from the hiring and partnering with new surgeons and physicians in the last few years, officials said.

Great Lakes Health is a parent organization that also includes Kaleida Health.
