A man in his 80s who had a history of diabetes mellitus and aortic valve replacement was referred to our hospital for treatment of early gastric cancer and underwent endoscopic submucosal dissection (ESD). Three days after ESD, the patient presented with low back pain and fever (38.7°). We initially considered adverse events associated with gastric ESD such as delayed perforation. Moreover, thromboembolism and infectious endocarditis were suspected because of his medical history. However, there were no remarkable findings suggestive of these diseases. Finally, based on the results of blood cultures and MRI, the diagnosis of pyogenic spondylitis (PS) was made. We administered antibiotics for 12 weeks, and the patient improved without neurological impairments. This case indicates that bacteraemia and subsequent PS can occur following gastric ESD. Physicians should not overlook the patient’s physical signs related to various adverse events after ESD.
