“…Because the CCD is located at the front end of the insertion section of the flexible electronic bronchoscope, it is susceptible to failure. The failure rate in the small-diameter bronchoscopes, as illustrated in Tables 2 and 3 was high, which is consistent with the research results of Nishizawa et al [ 13 ]. The shorter the external diameter, the more vulnerable a flexible bronchoscope is to damage.…”

“…(3) Pressure marks in the insertion tube, damage to the forceps channel, and water leakage. The causes consisted of damage to the interior surface of the flexible bronchoscope while removing the foreign body or taking tissue samples for biopsy [ 13 ], improper use of a cleaning brush during the cleaning procedure [ 14 ] (for example, mismatch between cleaning brush size and inner diameter of the bronchoscope might cause scratches on the interior surface of the bronchoscope during cleaning; or the cleaning brush had become bent and deformed after being used for a long time, but the cleaning person insisted on using it to clean the bronchoscope), not putting the pediatric flexible bronchoscope into the transport bin during transportation, coiling the bronchoscope too tightly, pressed front end, and vibration or shaking during transportation. In addition, the insertion section shook violently and collided with the host when the flexible bronchoscope was hung on the host on standby.…”

Background Frequent repairs of pediatric flexible bronchoscopes can lead to a huge financial burden for the hospital. This study aimed to investigate the common causes of the failures in pediatric flexible bronchoscopes and propose the measures to prevent the failures. Methods This was a retrospective study. We collected repair information of the pediatric flexible bronchoscopes reprocessed in the Department of Sterile Processing at a hospital between September 1, 2018 and September 1, 2022 in order to investigate the causes and possible factors associated with the failures in pediatric flexible bronchoscopes. Results The Department of Sterile Processing staff reprocessed the pediatric flexible bronchoscopes 4280 times. A total of 29 failures were identified. The failure rate was 0.678%. The average repair cost was USD7246.60. The common failures in the pediatric flexible bronchoscopes included dim video image, black dots, improper video image display or no image during angulation adjustment, and pressure marks in the insertion tube. The failure rates in flexible electronic bronchoscopes and small-diameter flexible bronchoscopes were 65.5% and 93.1%, respectively. The failure rate in the pediatric flexible bronchoscopes reprocessed by the staff members with less work experience was 75.9%. Conclusion The failure rate in the pediatric flexible bronchoscopes was not high but the repair costs were extremely high. The types and size of the flexible bronchoscopes and work experience of the staff members responsible for bronchoscope reprocessing were the possible factors associated with the failure rate in the pediatric flexible bronchoscopes. It is advisable to further optimize the central workflow and management mode for reprocessing the pediatric flexible bronchoscopes, thereby extending their useful life and reducing costs.

Background and Aim: Endoscopy-based Kyoto classification predicts the risk of Helicobacter pylori infection and gastric cancer; however, the change in score following H. pylori eradication remains unknown. We retrospectively compared the Kyoto score before and after H. pylori eradication. Methods: H. pylori-positive patients who underwent baseline esophagogastroduodenoscopy (EGD), successful H. pylori eradication, and surveillance EGD were enrolled. The Kyoto score is a sum of scores for atrophy (Kimura-Takemoto atrophicborder classification none or C1: 0, C-II or C-III: 1

BACKGROUND We have previously reported that Helicobacter pylori ( H. pylori )-associated nodular gastritis could occur in both the antrum and the cardia. Cardiac nodularity-like appearance (hereafter, called as cardiac nodularity) had a high predictive accuracy for the diagnosis of H. pylori infection. In the previous study, we included only the patients who were evaluated for H. pylori infection for the ﬁrst time, and excluded patients with a history of eradication. Therefore, the prevalence and clinical features of cardiac nodularity remains unknown. AIM To perform this cross-sectional study to explore the characteristics of cardiac nodularity. METHODS Consecutive patients who underwent esophagogastroduodenoscopy between May, 2017 and August, 2019 in the Toyoshima Endoscopy Clinic were enrolled in this study. We included H. pylori -negative, H. pylori -positive, and H. pylori -eradicated patients, and excluded patients with unclear H. pylori status and eradication failure. H. pylori infection was diagnosed according to serum anti- H. pylori antibody and the urea breath test or histology. Cardiac nodularity was defined as a miliary nodular appearance or the presence of scattered whitish circular small colorations within 2 cm of the esophagogastric junction. Nodularity was visualized as whitish in the narrow-band imaging mode. We collected data on the patients’ baseline characteristics. RESULTS A total of 1078 patients were finally included. Among H. pylori -negative patients, cardiac nodularity and antral nodularity were recognized in 0.14% each. Among H. pylori -positive patients, cardiac nodularity and antral nodularity were recognized in 54.5% and 29.5%, respectively. Among H. pylori -eradicated patients, cardiac nodularity and antral nodularity were recognized in 4.5% and 0.6%, respectively. The frequency of cardiac nodularity was significantly higher than that of antral nodularity in H. pylori -positive and -eradicated patients. The frequencies of cardiac nodularity and antral nodularity in H. pylori -eradicated patients were significantly lower than those in H. pylori -positive patients ( P < 0.001). The patients with cardiac nodularity were significantly younger than those without cardiac nodularity ( P = 0.0013). Intestinal metaplasia score of the patients with cardiac nodularity were significantly lower than those without cardiac nodularity ( P = 0.0216). Among H. pylori ...
