Manufacturer Narrative

Since the literature described "surgical scissors (13b1x00277000028)", olympus selected "fs-3l-1" as a representative product.The product was unknown but a representative product was chosen for processing purposes.The device has not been returned to olympus for evaluation.The device history record was unable to be reviewed for this device since the serial and/or lot number was not provided.However, olympus only releases products to market that meet all manufacturing specifications and final product release criteria.Based on the results of the investigation, the relationship between the device and the adverse event cannot be confirmed.There is no evidence of an olympus device malfunction.Therefore, the root cause cannot be determined.Olympus will continue to monitor field performance for this device.

Event Description

Olympus reviewed the following literature titled "endoscopic internalization by cutting versus removal of the endoscopic transpapillary naso-gallbladder drainage tube in preoperative management of acute cholecystitis: a retrospective multicenter cohort study." abstract background: endoscopic transpapillary naso-gallbladder drainage (engbd)has been reported to be an effective treatment option for acute cholecystitis.At our institution, engbd was first placed for external fistula management, and endoscopic internalization by cutting was performed, shifting to endoscopic transpapillary gallbladder stenting (egbs) after improvement of cholecystitis.However, there has been no comparative study to define which preoperative management is better: converting engbd to egbs or removing engbd.The study aimed to compare the incidence rate of the late adverse events (aes) related to biliary system between shifting from engbd to egbs and removal of engbd.Methods: we retrospectively studied 122 patients who underwent engbd for acute cholecystitis between january 2010 and october 2022.The patients were divided into two groups: the cutting group (converting engbd to egbs) and the removal group (removal of engbd).The short and late clinical outcomes we recompared between groups.Results: endoscopic transpapillary naso-gallbladder drainage was successfully placed in 78.6% (96/122), and elective cholecystectomy was performed in 31 and 36 patients in the cutting and removal groups, respectively.The cumulative late-ae rates were 6.4% and 33.3% (p =.007), with a median waiting period for elective cholecystectomy of 58 and 33 days (p =.390) in the cutting and removal groups, respectively.In the multivariate analysis, only endoscopic internalization by cutting was an independent factor affecting late aes.Conclusion: endoscopic internalization by cutting engbd after the resolution of acute cholecystitis was considered effective in reducing the risk of late aes during the waiting period for an elective cholecystectomy.Type of adverse events (ae)/number of patients: pancreatitis as early aes of engbd 2 patients, bleeding as early aes of engbd 1 patient , cystic duct injury as early aes of engbd 1 patient , migration as procedure (endoscopic internalization by cutting engbd)-related adverse event 3 patients , late adverse events including recurrence of cholecystitis and cbds (common bile duct stone) 14 patients.This literature article requires 3 reports.The related patient identifiers are as follows: -(b)(6) :kd-211q-0725.-(b)(6) :fs-5l-1.-(b)(6) :fs-3l-1.This medwatch report is for patient identifier (b)(6).There is no report of any olympus device malfunction in any procedure described in this study.
