Background - Percutaneous endoscopic gastrostomy (PEG) is a surgical procedure performed to maintain nutrition in the short- or long-term. During the procedure, a feeding tube that delivers either a liquid diet, or medication, via a clean or sterile delivery system, is placed surgically through the anterior abdominal wall. Those undergoing PEG tube placement are often vulnerable to infection because of age, compromised nutritional intake, immunosuppression, or underlying disease processes such as malignancy and diabetes mellitus. The increasing incidence of methicillin-resistant Staphylococcus aureus (MRSA) contributes both an additional risk to the placement procedure, and to the debate surrounding antibiotic prophylaxis for PEGtube placement. The aimof surgical antimicrobial prophylaxis is to establish a bactericidal concentration of an antimicrobial drug in the patient's serumand tissues, via a brief course of an appropriate agent, by the time of PEG tube placement in order to prevent any peristomal infections that might result from the procedure. Objectives - To establish whether prophylactic use of systemic antimicrobials reduces the risk of peristomal infection in people undergoing placement of percutaneous endoscopic gastrostomy tubes. Search strategy - For this second update, we searched the Cochrane Wounds Group Specialised Register (searched 16 February 2011); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 1); Ovid MEDLINE (1950 to February Week 1 2011); Ovid MEDLINE (In-Process and Other Non-Indexed Citations February 15, 2011); Ovid EMBASE (1980 to 2011 Week 06); and EBSCO CINAHL (1982 to 11 February 2011). Selection criteria - Randomised controlled trials (RCTs) evaluating the use of prophylactic antimicrobials during PEGtube placement, with no restrictions regarding language of publication, date of publication, or publication status. Data collection and analysis - Both authors extracted data and assessed study quality. Meta-analyses were performed where appropriate.
