Postpolypectomy fever in patients with serious infection: a report of two cases

Abstract

Abstract Background Postpolypectomy fever (PPF) is a rare complication in patients after colonoscopy. Because of the absence of evidence of microperforation and abdominal tenderness, patients with PPF usually present mild clinical symptoms with a good prognosis. Case presentation In this study, all patients who underwent colonoscopic examination in our hospital between January 2019 and December 2019 were enrolled. Of these, two patients developed PPF after polypectomy, exhibiting serious infection without definitive fever foci. One patient experienced rapidly aggravated type 1 respiratory failure and abnormal hepatic function, which were attributed to colonoscopy-associated infection. After active antibiotic therapy, both patients were discharged without any complications. Conclusions In summary, our study provides novel insights into patients with PPF who develop serious infections with life-threatening complications.
