Endoscopy Antibiotic Guidelines

1. Endocarditis

  • For endoscopic procedures, antibiotic prophylaxis should no longer be routinely given in circumstances where the sole aim is the prevention of endocarditis. Click here for further information.
  • Antibiotic prophylaxis is recommended for patients with profound neutropaenia and/or immunosuppression (e.g. advanced haematological malignancy, history of organ transplantation) who undergo procedures that are associated with a high risk of bacteraemia. Procedures associated with high risk of bacteraemia include oesophageal dilatation, variceal injection, laser palliation of cancer, and ERCP in patients with biliary obstruction. 
  • If prophylaxis against infective endocarditis is required , the recommended regime is:

Amoxicillin 1g iv plus Gentamicin 120 mg iv at induction, followed by Amoxicillin 500 mg po 6 hours later.
If current/previous MRSA positive ADD:
Teicoplanin iv stat at induction
Dose:
<50kg:             600mg
50-100kg:       800mg
>100kg:          1200mg

For patients allergic to penicillin (see explanatory notes):
Teicoplanin iv stat at induction
Dose:
<50kg:             600mg
50-100kg:       800mg
>100kg:          1200mg
plus
Gentamicin 120 mg iv stat at induction

  •  The possibility of infective endocarditis should be considered in patients who develop symptoms and signs of infection during the weeks following an endoscopic procedure.  Such patients should undergo prompt investigation and appropriate treatment.   

 

 

2. ERCP

  • Patients with ongoing cholangitis (or other infections for which therapeutic endoscopy is indicated as part of their management plan) should already have been established on appropriate antimicrobial therapy. See GHNHSFT biliary tree infection antibiotic guidelines for details. If the patient has biliary sepsis and endocarditis risk factors then tazocin or meropenem should be used for treatment as these agents have enterococcal cover. 
  • Routine prophylaxis for ERCP is not necessary in most other circumstances provided that adequate biliary decompression can be achieved.
  • There are specific circumstances where antibiotic prophylaxis should be given routinely to cover ERCP.  These include: 

 Patients at risk of endocarditis

Patients with severe neutropaenia and/or haematological malignancy and/or profound immunosuppression (e.g. organ recipient)

Patients with biliary disorders, such as primary sclerosing cholangitis or hilar cholangiocarcinoma in whom it can be anticipated that complete biliary drainage will be difficult or impossible to achieve during one procedure

Patients with pancreatic pseudocyst.

  • When prophylaxis for ERCP is required, the recommended regime is : (Click here)
  • For combined ERCP and  infective endocarditis prophylaxis : 

Ciprofloxacin 750 mg po stat 1-2 hours before the procedure plus Amoxicillin 1g iv plus Gentamicin 120 mg iv at induction, followed by Amoxicillin 500 mg po 6 hours later
If current/previous MRSA positive ADD:
Teicoplanin iv stat at induction
Dose:
<50kg:             600mg
50-100kg:       800mg
>100kg:          1200mg

For patients allergic to penicillin (see explanatory notes):
Ciprofloxacin 750 mg po stat 1-2 hours before the procedure
plus
Teicoplanin iv stat at induction
Dose:
<50kg:             600mg
50-100kg:       800mg
>100kg:          1200mg
plus
Gentamicin 120 mg iv stat at induction

 

 

3. PEG

  • Patients having a percutaneous endoscopic gastrostomy (PEG) or jejunostomy (PEJ) should  receive:- (Click here)
  • Patients already receiving broad spectrum antibiotics do not require additional prophylaxis for PEG.   

 

4. Variceal Bleeding

  • Patients with suspected variceal bleeding, or patients with decompensated liver disease who develop acute gastrointestinal bleeding, should have already been established on intravenous antibiotics before undergoing endoscopy as per local guideline
