Table 1 Evidence-based literature review for gastroendoscopy-associated Acinetobacter bacteremia

Ref.	Country	Evaluation	Risk factors	Microbiology	Treatment	Outcome
Norfleet et al[3], 1981	United States	447 patients have been evaluated, of which 6% had bacteremia after upper gastrointestinal endoscopy	Upper gastrointestinal endoscopy	One case with Acinetobacter sp infection	NM	NM
Maulaz et al[4], 2003	Brazil	The bacteremia incidence in cirrhotic patients submitted to variceal ligation was 2.5%, showing no difference from the control groups	Endoscopic variceal ligation or esophagogastroduodenoscopy only	One case with Acinetobacter lwoffii infection	NM	One case with Acinetobacter lwoffii infection is survived
Oh et al[5], 2007	South Korea	A total of 364 patients who underwent PTC were included in the study	Cholangitis and bacteremia were associated with percutaneous transhepatic biliary drainage and tract dilation, catheter migration and blockage with tract maturation, and bile duct injury with PTC	NM	NM	NM
Lai et al[6], 2008	Taiwan	Case report	Endoscopic procedure	Initial, polymicrobes (Acinetobacter baumannii, Klebsiella pneumoniae and Enterococcus Faecalis), then became Acinetobacter genomic species 13TU at day 14	Ceftazidime and ampicillin-sulbactam, then intravenous gentamicin and ciprofloxacin (parenteral antibiotics for 4 wk) then followed by oral ciprofloxacin and trimethoprim-sulfamethoxazole (for another 13 d) , antibiotics used for 61 d in total	Survived
