Scalise was wounded when a gunman opened fire at a Republican baseball practice in Virginia on Wednesday.
Several other people were also injured in Wednesday's shooting before Scalise's security detail and other police officers gunned down the assailant, who later died. Because the bullet shattered, there may be hundreds of fragments in Scalise's body and doctors do not intend to try to remove them all, Sava said.
MedSTAR hospital has not issued an update on Scalise's condition last night when they said he was in critical but stable condition.
On Friday, a senior doctor at the hospital said Scalise, 51, had been at the brink of death because of extensive blood loss when he arrived at the hospital by helicopter. Although infection remains a risk, Scalise's vitals had stabilized Friday afternoon.

Congressman Steve Scalise is in surgery for a third time at a Washington, D.C. hospital. The round did substantial damage to bones, internal organs, and blood vessels according to Sava.
The hospital where Rep. Steve Scalise is recuperating from a gunshot wound says he "remains in critical condition, but has improved in the last 24 hours".
During the baseball practice on Wednesday, a gunman opened fire, injuring Scalise, congressional staffer Zach Barth, Tyson Foods lobbyist Matt Mika and two members of the Capitol Police force, Crystal Griner and David Bailey.
Scalise was shot in the hip, and sustained grievous injuries as the bullet traveled through his pelvis and injured internal organs.
A former congressman who formerly held the seat now held by Scalise says his condition is serious. Democrats sent the trophy they earned to Scalise's office after the game. But he will remain in the hospital for "a considerable period of time" and faces additional operations.
Since then he has had more than one surgery and doctors expect he will continue to have more in the near future.
"The Scalise family greatly appreciates the outpouring of thoughts and prayers", the statement concludes.
"It's been much more hard than people even thought at the time".
"By playing tonight we are showing the world that we will not be intimidated by threats, acts of violence or assaults on our democracy", said US President Donald Trump, appearing on the park's giant screen but not attending.
"The president says that because of the "tremendous pain and suffering he's now enduring. our country will perhaps become closer, more unified".
Investigators said in a statement that the Federal Bureau of Investigation has searched the van, which was parked not far from the Alexandria, Virginia, baseball field where Wednesday's shooting took place.
The FBI said that the shooter's weapons found at the scene - a 9mm handgun and 7.62mm caliber rifle - had been legally purchased.
The president made his comments as he spoke in Miami to announce a new policy on Cuba. Dr. Jack Sava of MedStar Washington Hospital Center said it's a "good possibility" that the Louisiana Republican will be able to return to work in his full capacity. The shooter was an IL man, James Hodgkinson, who had lashed out against President Donald Trump and Republicans over social media.
Republicans and Democrats are fighting for bragging rights in their annual Congressional Baseball game, and doing so as one unit - Team Scalise. Scalise is a member of the team and had been fielding balls at second base in preparation for the game when he was shot.
