He was diagnosed with acute appendicitis and underwent emergency laparoscopic appendicectomy. Cefmetazole was administered as a perioperative antibacterial drug. Postoperatively, the abdominal findings improved. However, on postoperative day three, bloody sputum and respiratory distress were observed. We performed thoracoabdominal computed tomography (CT) and observed bilateral pleural effusion and mottled frosted glass shadows extending to both lung fields. ARDS was diagnosed. We treated the patient with steroids and sivelestat sodium and switched the antibacterial drug to meropenem. The patient\u2019s general condition improved. After the patient was treated, <jats:italic>Bacteroides ovatus<\/jats:italic> was isolated from preoperative blood culture, which was resistant to cefmetazole.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>We encountered a case in which ARDS due to sepsis was caused by <jats:italic>Bacteroides ovatus<\/jats:italic> after acute appendicectomy.
