A case of recurrent infective endocarditis following colonoscopy

Antibiotic prophylaxis for GI endoscopy

“…Despite an estimated 14.2 million colonoscopies, 2.8 million flexible sigmoidoscopies, and perhaps as many upper endoscopies performed in the United States each year, 3 only approximately 25 cases of IE have been reported with temporal association to an endoscopic procedure. [4][5][6] There are no data demonstrating a causal association between endoscopic procedures and IE or that antibiotic prophylaxis prior to endoscopic procedures protects against IE. Finally, much of the existing data reflects estimated risk associated with conventional endoscopic techniques.…”

“…(4 444) 4. We recommend that antibiotic prophylaxis be administered before ERCP in patients who have had liver transplantation or who have known or suspected biliary obstruction, where there is a possibility of incomplete biliary drainage.…”

Bacterial Endocarditis Following Deep Enteroscopy: Is Prophylaxis Warranted?

“…6 In a recent comprehensive review of the literature, 25 cases of endocarditis secondary to endoscopy were identified, but none were secondary to deep enteroscopy. 7–9 Similarly, in a case series by Nelson et al, 7 cases of endocarditis in the setting of EGD and 1 case secondary to colonoscopy were described. 3…”

Enterococcus faecalis Endocarditis After Endoscopic Mucosal Resection of a Large Sessile Colonic Polyp

“…Similarly, Sekino et al reported E. faecalis endocarditis in a patient with prosthetic valve replacement after piecemeal resection of a 30-mm tubulovillous adenoma. 5 It is possible that the large area of submucosal exposure to colonic bacteria increases the risk of bacteremia and seeding of a heart valve. This complication of EMR of large colorectal polyps appears very rare.…”
