Antibiotic Prophylaxis in Endoscopic and Minimally Invasive Surgery

Abstract

Infections are unusual following minimally invasive surgery but antibiotic prophylaxis is given in the same way as for the open surgery equivalents. Most prophylactic regimens have not been subjected to randomised placebo controlled trials. Antibiotic prophylaxis has been shown to be beneficial in transurethral resection of the prostate. In endoscopic retrograde cholangiopancreatography (ERCP) the incidence of bacteremia, but not cholangitis, is reduced by prophylaxis and some do not recommend its routine use. For arthroscopies and laparoscopies infection is too rare to warrant prophylaxis. There is a theoretical risk of infection in that endoscopes cannot withstand autoclaving so only high level disinfection can be used between patients. However, for most minimally invasive operations, the small wound size, reduced immune challenge and rapid recovery of the patient outweigh any disadvantages compared with open surgery.
