Despite the current sterile techniques used for all surgeries, infections can occur. The seriousness and subsequent treatment options will vary, depending upon the location.
Infections can range from very minor ones that only need to be treated with antibiotics, to very major infection, requiring a surgery to treat it. For example, skin infections occur in about 1 out of 100 procedures and usually take a few days to occur. Internal infections are much rarer; however, they are more serious.
In most cases, they require hospitalization and IV antibiotics and, in rare cases, a repeat surgery. Because of the infection, it is possible that it could increase your likelihood of developing adhesions which can cause pain and increased risk for a bowel obstruction.
Life-threatening complications are a very rare occurrence. If an infection does develop, your doctor will discuss the treatment options and expected outcomes with you.
