1. Bacteremia after endoscopic procedures
a. esophageal dilation carries the highest risk
b. banding may have a second peak of bacteremia 5 to 7 days later when the bands slough off
c. cleaning or disinfecting dilators prior to performing esophageal dilation markedly reduces the risk of bacteremia
d. the rate of bacteremia after esophageal dilation ranges from 5% to 62%
e. risk may be increased when dilating malignant strictures or passing several dilators.
True or False
2. The mean frequency of bacteremia after EGD is about 4.1%, it usually lasts < 30 minutes.
3. Transient bacteremia occurs in about 15% of cases when sclerotherapy is performed, at times, bacteremia may persist up to 24 hours.
4. Antibiotic prophylaxis is recommended for patients with obstructed bile ducts who are undergoing ERCP.
5. Sclerotherapy is followed by SBP in about 12% of cases.
6. Banding is associated with a mean rate of bacteremia of about 9%.
7. Local wound infection after PEG placement occurs in about 7% to 33% of cases, the risk is decreased significantly by the use of pre-procedure antibiotics
