Saturday was a great day for a party, and John Kreider and Jessie Reider had a great reason to celebrate.

Their family gathering outside of Elizabethtown marked the first anniversary of the surgery that saved Kreider's life.

Two years ago, he was suffering from cirrhosis of the liver.

"My skin was yellow, my eyes were bright yellow, it was miserable," Kreider recalled. He needed a liver transplant. He was put on the waiting list to get a liver from a deceased donor. Then another option came up. It's called a living donor transplant, and until Kreider's surgery it had never before been preformed in South Central Pennsylvania.

Kreider's sister, Jessie Reider, decided she was going to go through rigorous testing to see if she could donate part of her liver to save her brother's life.

"I went ahead and said, 'I'm going to try this'," Reider said. "I was the only person who matched."

When doctors at the Milton S. Hershey Medical Center told her the matching results, Reider could not believe the odds. "What makes it even more special is John is adopted into this family," she said, marveling that she could be matched so well with someone who was genetically not her sibling.

Reider would give up 60 percent of her liver to Kreider during a complicated procedure at the Hershey Medical Center. If the surgery worked, Reider's liver would grow back and her brother would be able to live a normal life. The siblings went under the knife on July 29, 2008.

A year later the surgery seems to be a massive success.

"I appreciate everything she did for me," Kreider said. "I'm back to work full time. I'm playing baseball with my kids. It's great."

"I saved him," Reider said with tears in her eyes. "I don't know how long he's going to live, but we made it a year, and that's what this is all about," she said, pointing to family and friends gathered around her. "I've got my brother back."
