Antibiotic Prophylaxis Before Percutaneous Gastrostomy

The purpose of this study is to evaluate the use of antibiotics (i.e. Kefzol) before
percutaneous gastrostomy performed in interventional radiology. Patient will be randomized
to receive antibiotics or placebo before the procedure, and the rates of skin infection
after the procedure will be determined between the two groups. This has never been studied
in our population of patients undergoing the procedure. However, antibiotics are routinely
given despite the lack of evidence. The investigators hypothesize that patient receiving
prophylactic antibiotics will have a decreased number of infections compared to placebo.
