Manufacturer Narrative
The subject device was not returned to olympus medical systems corp. (omsc) for evaluation. Therefore, the exact cause of the reported event could not be conclusively determined. Since the serial number is unknown, the device history record could not be reviewed. However, omsc has only shipped devices that passed the inspection. In the literature, there is no description of the device's malfunction.
 
Event Description
On (b)(6) 2021, olympus medical systems corp. (omsc) received the literature titled "endoscopic submucosal dissection for colorectal neoplasms in proximity or extending to a diverticulum". In this study, 47 colorectal lesions treated with endoscopic submucosal dissection (esd) between january 2014 and april 2019 were included. The 47 subjects consisted of 27 male and 20 female patients with a mean age of (b)(6). In the literature, it was reported that the following. "delayed perforation, delayed bleeding, fever, and abdominal pain occurred in 1, 1, 4, and 5 patients, respectively. "two days after the esd, a strong tenderness was observed in the right lower abdomen, and ct revealed free air around the treatment area. The patient was diagnosed as having developed post operative delayed perforation, and emergency surgery was performed. Based on the available information, reported delayed perforation, delayed bleeding, fever, abdominal pain were not reported in a direct relationship with the olympus products. However, omsc assumes that the delayed perforation and the delayed bleeding might be related to the subject device since the subject device was used for the procedure. And, omsc assumes that the delayed perforation might be caused or contributed to a death or serious injury. Omsc assumes that the delayed bleeding, the fever and the abdominal pain were not serious due to the following report: *delayed bleeding was successfully controlled by endoscopic hemostasis. *four patients developed high-grade fever (38°c) and five patients developed transient severe abdominal pain; however, all of these patients improved conservatively with antibiotics. Therefore, omsc assumes that the delayed perforation was an adverse event to submit. Based on the available information, specific information on the subject device and the patient (except for some, for example, age) were not provided. There is no description of the device's malfunction. Omsc will submit one medical device report (mdr) of the subject device for the delayed perforation.
