Event Description

Zhou-2020 (evo-c): safety and efficacy of through-the-scope placement of colonic self-expandable metal stents without fluoroscopic guidance: a retrospective cohort study.Retrospective study carried out in patients undergoing endoscopic sems insertion with or without fluoroscopic guidance for malignant large-bowel obstruction in a single tertiary medical center.Sems placement was performed using a 1-channel endoscope with working channel = 3.7 mm diameter (cf-h260; olympus co., (b)(4)).The stenting procedures are briefly summarized as follows: in the f group, a hydrophilic guidewire and a biliary dilation catheter (cook medical, (b)(4)) were inserted through the stricture.Then, the guidewire was removed and a water-soluble contrast agent was injected through catheter to insure proper entry into the proximal lumen and to evaluate the length of the stenosis under fluoroscopy.Then, after the guidewire was reinserted and the dilation catheter was withdrawn, the stent was advanced through the endoscope across the lesion and deployed under endoscopic and fluoroscopic guidance.In the nf group, procedures were otherwise the same as in f group, except that fluoroscopy was not used and contrast agent injection was omitted (off-label use).Guidewire and dilation catheter were considered across the stricture when they were easily advanced without resistance.When resistance was felt, the guidewire tip direction was adjusted.Insertion was retried until easy advance of at least 10 cm of both the guidewire and the catheter.The stent was deployed only under endoscopic monitoring.Stent length must allow for at least 2 cm of additional exposure to each end of the stricture.If one stent was not long enough to cover the obstruction, a second stent was used and at least 3 cm of overlap was obtained.In 1 patient, a stent was placed without fluoroscopic guidance (off-label) and the following aes occurred which required intervention: stent occlusion due to tumour ingrowth.Stent occlusion occurred 5 months after procedure due to tumor ingrowth that was managed endoscopically with another sems placement.

Event Description

Supplemental report is being submitted due to the completion of the investigation.

Manufacturer Narrative

510(k) number: k163468.Device evaluation: the evolution colonic devices of unknown lot number involved in this complaint were not available for evaluation.With the information provided, a document based investigation was conducted.This file was created from the attached journal article to capture ¿zhou-2020 (evo-c): safety and efficacy of through-the-scope placement of colonic self-expandable metal stents without fluoroscopic guidance: a retrospective cohort study.Additional complaint files: (b)(4) were opened as a result of this paper.Reference "zhou-2020." lab evaluation: n/a.Document review including ifu review: as the evolution colonic devices are from unknown lot number, a review of the relevant manufacturing records cannot be conducted.Prior to distribution, all evolution colonic devices are subjected to functional checks and visual inspection to ensure device integrity.These inspections and functional checks are outlined in internal procedures in place at cirl.The notes section of the instructions for use, ifu0052-11, which accompanies this device instructs the user "stent should be placed endoscopically with fluoroscopic monitoring ¿ after stent placement the following major adverse event occurred, stent occlusion due to tumour ingrowth.Stent occlusion occurred 5 months after procedure due to tumor ingrowth that was managed endoscopically with another sems placement.There is evidence to suggest that the customer did not follow the instructions for use.Image review: n/a.Root cause review: a definitive root cause could be determined from the available information.From the journal article it is known that the user used the device off-label, stents were placed without fluoroscopic guidance which is off label as per ifu.Summary: complaint is confirmed based on the customer's testimony.No patient death was reported.Complaints of this nature will continue to be monitored for potential emerging trends.

Event Description

Supplemental correction report is being submitted due to an update the complaint description.Initial complaint description: in 1 patient, a stent was placed without fluoroscopic guidance (off-label) and the following aes occurred which required intervention.Stent occlusion due to tumour ingrowth.Stent occlusion occurred 5 months after procedure due to tumor ingrowth that was managed endoscopically with another sems placement.Updated complaint description: this complaint was opened to capture stent occlusion due to tumour ingrowth.Stent occlusion occurred 5 months after procedure due to tumor ingrowth that was managed endoscopically with another sems placement.

Manufacturer Narrative

510(k) number: k163468.Device evaluation: the evolution colonic devices of unknown lot number involved in this complaint were not available for evaluation.With the information provided, a document based investigation was conducted.This file was created from the attached journal article to capture ¿zhou-2020 (evo-c): safety and efficacy of through-the-scope placement of colonic self-expandable metal stents without fluoroscopic guidance: a retrospective cohort study.This file was opened to capture major adverse event.As the conclusion of this article ¿colonic sems placement without fluoroscopy is as safe and effective as the conventional fluoroscopically guided approach.This new method significantly reduced the procedure time¿, which indicated a benefit without fluoroscopy as well as a safety and efficacy.Lab evaluation: n/a.Document review including ifu review: as the evolution colonic devices are from unknown lot number, a review of the relevant manufacturing records cannot be conducted.Prior to distribution, all evolution colonic devices are subjected to functional checks and visual inspection to ensure device integrity.These inspections and functional checks are outlined in internal procedures in place at cirl.As per the instructions for use, ifu0052, which accompanies this device it informs the user about the potential complications "additional contraindications include, but are not limited to : "stent occlusion.¿ there is no evidence to suggest that the customer did not follow the instructions for use.Image review: n/a.Root cause review: a definitive root cause could not be determined from the available information.A possible root cause could be attributed the patient¿s pre-existing condition.From the information provided it is known that the patient had malignant colorectal cancer.Summary: complaint is confirmed based on the customer and/or rep testimony.No patient death was reported.Complaints of this nature will continue to be monitored for potential emerging trends.
