Background: Dietary supplements are commonly used in Japan. Although some dietary supplements can affect perioperative conditions owing to abnormalities in the blood coagulation system, there are no reports examining the duration of withdrawal and the risk of complications during bronchoscopy. We aimed to retrospectively review the safety and withdrawal periods of supplements before bronchoscopy in patients who regularly consumed dietary supplements.
Materials and Methods: This single-center retrospective observational study was conducted at Tottori University Hospital. Patients who underwent bronchoscopy between January 2019 and December 2019 were validated and examined. We examined patient backgrounds, including consumption of dietary supplements and the type of bronchoscopy procedure. Data regarding the duration of dietary supplement withdrawal and complications during and after bronchoscopy were also collected.
Results: A total of 351 bronchoscopy procedures were performed during the observation period. Of these, 69 bronchoscopies (23.3%) were performed in patients who regularly used dietary supplements. There were 19 cases of invasive bronchoscopy in patients who regularly used dietary supplements with bleeding risk. The median withdrawal period for the dietary supplements was 14 days. The incidence of bleeding complications from invasive bronchoscopy did not differ significantly among the patients who took antithrombotic agents or dietary supplements with bleeding risk.
Conclusions: On the basis of this retrospective analysis, dietary supplements may be considered safe if they are withdrawn at a significant interval (≥7 days) before patients undergo invasive bronchoscopy.
