It was reported to boston scientific corporation that a hot axios stent was implanted in a transgastric position to treat a pancreatic walled-off necrosis during an inpatient stent placement procedure performed on (b)(6) 2019.The stent was placed as part of the (b)(6) clinical trial.The patient was enrolled into the clinical trial on (b)(6) 2019.According to the complainant, on (b)(6) 2019, the patient developed sepsis, and an abdominal computer tomography (ct) was performed.The ct showed signs of a new systemic infection, including fever, leukocytosis, and visualization of gas bubbles within the necrotic tissue.A necrosectomy procedure was performed on (b)(6) 2019 for insufficient won size reduction and to treat the patient's sepsis.The patient's won was measured to be greater than 3cm.The hot axios stent was confirmed to be patent and draining pus, necroses, and debris.Another necrosectomy procedure was performed on (b)(6) 2019 for insufficient won size reduction.The patient's won was again measured to be greater than 3cm.The hot axios stent was confirmed to be patent and draining pus, necroses, and debris.On (b)(6) 2019, under ct fluoroscopy guidance, serial dilation was performed, and a 12 french pigtail stent was placed due to the patient's illness.Insufficient won size reduction was noted.On (b)(6) 2019, two double pigtail stents were placed and balloon dilation of the tract was performed.The patient's won was measured to be less than 3cm.Drainage and patency of the hot axios stent were confirmed.According to the complainant, the sepsis was unlikely to be related to the axios stent and stent placement, and probably related to the complex necrotic debris.Reportedly, the patient's hospitalization was prolonged as a result of this event.As of (b)(6) 2019, the patient's condition was reported to be recovered.
