For almost any surgery you have, bleeding will happen. There are different reasons for bleeding during surgery and different ways to stop bleeding. Bleeding usually stops by itself. If it doesn't stop right away, your doctor can use an instrument called cautery to stop the bleeding. If the bleeding becomes dangerous, or there is serious damage to a major blood vessel, the type of surgery you have might change. The surgery would change to an open surgery. This type of surgery gives your doctor more ways to fix the bleeding and keep you from bleeding too much. An open surgery means you will have a larger cut in your abdomen. Sometimes the bleeding shows up after the surgery. If this happens you might need another surgery to stop the bleeding. If the bleeding is very serious, you might need to have a blood transfusion. This means you get extra blood from the blood bank. Getting blood like this is usually safe. The blood is tested for AIDS and other diseases before it gets to you. Some people have gotten diseases or infections from blood, though, but this doesn't happen very often. Only about 1 in 100,000 people get Hepatitis C, and 1 in 200,000 get Hepatitis B from blood. And only about 1 in 600,000 people get HIV from blood.
