Do you know anyone who had surgery for abscesses on the liver?

One of my best friends has been in the hospital for 7 days with abscesses on the liver. He has multiple abscesses and a fever over 102 for days. The antibiotics are not helping and he is going in for surgery on Friday. I was reading and found this, which made me feel anxious about his prognosis http://www.nlm.nih.gov/medlineplus/ency/article/000261.htm Does anyone know someone who had this surgery and how did it go? Should I be worried for him? He is strong and in his 40’s but apparently it can lead to sepsis, which I know is deadly. Please let me know if you have any experience with this and how his recovery will be, too. Thanks.
