Objectives: The benefit of antibiotic prophylaxis in percutaneous endo
scopic gastrostomy is controversial. The aim of this study is to deter
mine whether prophylactic antibiotic treatment with Cefazolin reduces
the incidence of peristomal infection after percutaneous endoscopic ga
strostomy. Methods: Of the 131 hospitalized or nursing home patients r
eferred for percutaneous endoscopic gastrostomy, 115 were enrolled in
a prospective randomized double-blind placebo controlled trial. Sixty-
one (group 1) were randomized in a double-blind fashion and received e
ither Cefazolin or saline pregastrostomy. Fifty-four patients (group 2
) were on antibiotics for prior medical indications pregastrostomy. Pa
tients had their peristomal area evaluated on a daily basis for 1 wk a
fter gastrostomy. Erythema and exudate were scored on a scale from 0 t
o 4; induration was scored on a scale of 0 to 3; a maximum score of 8
or higher or the presence of pus was criteria for infection. Results:
Wound infection occurred in 4 of 30 (13%) participants receiving Cefaz
olin and in 6 of 31 (19%) participants receiving saline (p > 0.5), In
the 54 patients on antibiotics for prior indications, wound infection
was observed in 2 subjects (3%). This finding was a significant differ
ence when compared with the placebo group (p < 0.02), Conclusions: A s
ingle dose of Cefazolin prophylaxis does not reduce the overall perist
omal wound infection in percutaneous endoscopic gastrostomy. Patients
receiving prior extended antibiotic therapy have fewer peristomal woun
d infections.
