REDUCING THE RISK OF PERISTOMAL INFECTION AFTER PEG PLACEMENT

DIGESTIVE ENDOSCOPY, Issue 4 2005
Iruru Maetani
Percutaneous endoscopic gastrostomy (PEG) was first described in 1980 as an effective means of enteral nutrition where oral intake is not possible. PEG placement is safe and has now replaced the nasogastric tube in patients who need long-term feeding. Although it is relatively safe with a very low associated mortality, minor complications, especially local and systemic infection, remain a problem. Of these, peristomal wound infections are the most common complication of PEG. In patients indicated for this procedure who are aged and/or frail, this complication may pose a critical problem. In the commonly used pull or push methods for PEG placement, the PEG tube is readily colonized by oropharyngeal bacteria. Infection of the PEG site is considered to be associated with contamination of the PEG catheter. There are important measures that should be taken to prevent peristomal infection. A number of rigorous studies have shown that prophylactic antibiotics are effective in reducing the risk of peristomal infection. As methicillin-resistant Staphylococcus aureus (MRSA) or other resistant organisms are emerging as a major pathogen in peristomal infection, however, currently recommended antibiotic prophylaxis regimens might be inappropriate. Alternative regimens and other approaches to prevent contamination of the PEG tube during the procedure are required. [source]

A systematic review of prophylactic antimicrobials in PEG placement

Aim., To establish whether prophylactic systemic antimicrobials reduce the risk of peristomal infection in placement of percutaneous endoscopic gastrostomies. Background., Percutaneous endoscopic gastrostomies, placed surgically through the anterior abdominal wall, maintain nutrition in the short or long term. Those undergoing percutaneous endoscopic gastrostomy placement are often vulnerable to infection. The increasing incidence of methicillin-resistant Staphylococcus aureus contributes an additional risk to the debate surrounding antibiotic prophylaxis. The aim of antimicrobial prophylaxis is to establish a bactericidal concentration of an antimicrobial drug in the patient, during placement. Design., Systematic review. Methods., We searched the Cochrane Wounds Group Specialised Register (July 2006); The Cochrane Central Register of Controlled Trials (The Cochrane Library 2006, Issue 2); handsearched wound care journals, relevant conference proceedings and bibliographies of publications identified, and contacted manufacturers and distributors of percutaneous endoscopic gastrostomy products. Randomised controlled trials were selected evaluating the use of prophylactic antimicrobials for percutaneous endoscopic gastrostomy placement, with no restrictions for language, date or publication status. Both authors performed data extraction and assessment of study quality. Meta-analysis was performed where appropriate. Results., Ten eligible randomised controlled trials were identified evaluating prophylactic antimicrobials in 1100 patients. All trials reported peristomal infection as an outcome and a pooled analysis resulted in a statistically significant reduction in the incidence of peristomal infection with prophylactic antibiotics (pooled OR 0·31, 95% CI 0·22,0·44). The relative reduction in risk of infection for those given antibiotics was 19% with the need to treat 5·8 patients to prevent one infection , NNT. Conclusions., Administration of systemic prophylactic antibiotics for percutaneous endoscopic gastrostomy placement reduces peristomal infection. Relevance to clinical practice., The nurse's role in endoscopy is expanding rapidly and demands that practice is based on the best available evidence. This systematic review seeks to make a contribution to best practice in percutaneous endoscopic gastrostomy placement. [source]

Meta-analysis: antibiotic prophylaxis to prevent peristomal infection following percutaneous endoscopic gastrostomy

Summary Background Despite numerous guidelines recommending prophylactic antibiotics prior to percutaneous endoscopic gastrostomy, their use remains controversial. Aim To conduct a systematic literature review and performed meta-analyses to determine the benefit of antibiotic prophylaxis for percutaneous endoscopic gastrostomy placement. Methods We performed a systematic literature review by searching healthcare databases and grey literature for randomized-controlled trials of antibiotic prophylaxis against wound infection after percutaneous endoscopic gastrostomy. Relative risks were calculated for individual trials and data pooled using fixed-effects model. Relative risk reduction, absolute risk reduction and number needed to treat were calculated and are reported with 95% confidence intervals. Results Ten randomized-controlled trials met the inclusion criteria and 1059 cases were pooled. Overall findings indicated that antibiotic prophylaxis resulted in a relative risk reduction of 64% and an absolute risk reduction of 15%. Number needed to treat to prevent one wound infection was 8. Cephalosporin prophylaxis was associated with a relative risk reduction of 64%, absolute risk reduction of 10% and number needed to treat of 10, whereas penicillin-based prophylaxis was associated with a relative risk reduction of 62%, absolute risk reduction of 13% and number needed to treat of 8. Conclusions Antibiotic prophylaxis prior to percutaneous endoscopic gastrostomy is effective in reducing the incidence of percutaneous endoscopic gastrostomy site wound infection. Based on sensitivity analyses, penicillin-based prophylaxis should be the prophylaxis of choice. [source]
