On december 17, 2020, olympus medical systems corp.(omsc) received the literature titled "needle tract seeding and abscess associated with pancreatic fistula after endoscopic ultrasound-guided fine-needle aspiration".This study was conducted endoscopic ultrasound-guided fine-needle aspiration (eus-fna) for a (b)(6) years old woman with pancreatic ductal adenocarcinoma (pda).In the literature, it was reported that needle tract seeding with simultaneous abscess associated with pancreatic fistula occurring after eus-fna for pda.The patient presented with a fever of 38 degrees celsius and abdominal discomfort 18 days after eus-fna for pda of the pancreatic tail with a retention cyst.An abscess associated with pancreatic fistula (apf) is secondary to main pancreatic duct injury was suspected.Simultaneous needle tract seeding was also strongly suspected because the eus-fna needle was believed to penetrate the main pancreatic duct within the tumor, causing tumor cells to come into contact with the pancreatic juice which subsequently leaked out into the needle tract.Distal pancreatectomy with partial gastrectomy was performed 4 months after eus-fna.Strong adhesion between the stomach and pancreas was observed.The pancreatic body/tail, upper stomach, eusfna and eus-cd needle tract, transverse colon, left adrenal gland, and spleen was removed en bloc with curative intent due to adhesion and suspected invasion.The post-surgical course was complicated by pancreatic fistula, which was managed conservatively.She presented with vomiting 3 months later, when she was diagnosed with liver metastases, peritoneal carcinomatosis, and duodenal obstruction near the ligament of treitz.She died 9 months after the needle tract seeding and apf and 5 months after the surgery.Based on the available information, detailed information of the subject device was not provided.Omsc will submit one medical device report (mdr) for needle tract seeding with simultaneous abscess associated with pancreatic fistula occurring after eus-fna with the subject device.
