Hemoclips are not magnetic resonance imaging (MRI)-safe, and are contraindications to MRI . Magnetic resonance imaging safety of surgical clips and staples De Silva, S.; Bampoe, S.; Scott, M. 2015-12-01 00:00:00 We read McCall et al. A secondary survey was then distributed to all original participants in July 2016. 1. Innovative clipping system for efficacy in flexible endoscopy. Please select any steps you may use as part of your pre-MRI endoclip screening protocol. Before having an MRI scan, you should tell medical staff if: you think you have any metal in your body ; you're pregnant or breastfeeding; The strong magnets used during the scan can affect any metal implants or fragments in your body. Similarly, none of the 28 centers in our secondary survey, representing approximately 157,000 annual patient visits, reported any knowledge of complications from endoscopic clips in MRI. Correct safety classification is as follows: Resolution Clip model, MRI conditional; LongClip, QuickClip, QuickClip2, and TriClip models, MRI unsafe [2]. The purpose of the secondary survey was to ask centers whether endoscopic clip screening practices had changed since the site received the primary survey results and whether they had ever encountered or heard reports of complications arising from performing MRI on persons with in situ gastrointestinal endoscopic clips. A canine study [3] showed a median of 8 weeks' retention for the Resolution Clip model. The clip is used to stop gastrointestinal (GI) tract bleeding, which is a condition that can be challenging to treat because of the variations among bleeds. Deployed into the gastrointestinal tract under endoscopic guidance, these hemostatic clips allowed safer and less invasive closure of tissue defects; control of gastrointestinal bleeding; securing of stents, catheters, and feeding tubes; and marking of internal anatomic structure for future surveillance or surgery [1]. Endoscopic Clip MRI Screening: A Canada-Wide Policy Survey. What MRI Sequences Produce the Highest Specific Absorption Rate (SAR), and Is There Something We Should Be Doing to Reduce the SAR During Standard Examinations? https://doi.org/10.1016/j.gie.2009.01.024. To put these findings into perspective, approximately 150,000 patients per year may be undergoing MRI without previous endoscopic clip–specific screening, according to reports from the 16 nonscreening centers in this surveyed population alone. If the clip is in your colon, it is important to tell your healthcare provider if you need an MRI. The Ethicon Endo-surgery clip is compatible with MRI. When the TriClip clip was attached to the gastric fold of dissected pig stomach, the force was strong enough to fully detach the clip from its place. Magnetic resonance imaging (MRI) is very safe and most people are able to have the procedure. Endoscopic clips like the Resolution Clip and Ethicon Endo-Surgery Clip models are labeled MRI conditional, meaning that MRI may be performed on patients with these clips but only under strict conditions, as outlined by the manufacturer [2]. These discrepancies existed despite the lack of survey time constraints or restrictions on referring to outside sources while completing the survey. ], We were not aware that some endoclips may not be MRI safe, We decided not to screen after review by a safety committee, Our local endoscopists use only MRI-safe clips, We tried screening for endoclips, but stopped because of limited yield/benefits. Twenty-eight of the 67 (42%) participating MRI sites responded to the secondary survey (24 screeners, four nonscreeners). Abstract Background: Endoscopic clipping devices are now available for treatment of GI hemorrhage and microperforations. Endoscopic Full Thickness Resection . Although in the past these endoscopic clips were largely ignored during pre-MRI patient screening, many centers now routinely screen for their presence. (Single choice), Consent needed before proceeding with MRI, Both waiver and consent needed before proceeding with MRI, MRI not performed regardless of consent/waiver. Published by Mosby, Inc. All rights reserved. Results represent number and percentage of centers that may, at any one time, use each step to assess for endoscopic clips. ‡ Clips that stay in place during surgical maneuvering while positioning the jaws around a structure have a … Screening was done by MRI technologists at 47 centers (92%), receptionists or booking clerks at 21 centers (41%), nurses at six centers (12%), and the ordering physician at five centers (10%). All other clips showed deflection in a magnetic field, but only the TriClip demonstrated detachment from gastric tissue, and hence should be considered MRI incompatible. www.mrisafety.com/SafetyInfoFromList.asp?LSub=34, www.fda.gov/downloads/MedicalDevices/DeviceRegulationandGuidance/GuidanceDocuments/ucm107708.pdf, Original Research. The concern is that torqueing of a ferromagnetic hemostasis clip in a strong magnetic field could lead to bleeding or injury at the site of biopsy / polypectomy. The purpose of this study was to determine whether and how MRI centers across Canada screen for endoscopic clips. For example, although labeled unsafe for MRI [2], the Long-Clip, QuickClip, QuickClip2, and TriClip models were each misclassified as MRI safe by two centers (4% of participants) and MRI conditional by seven to nine centers (15–19% of participants). We navigated the telephone directory to reach the chief MRI technician at the site, sometimes referred to as the charge tech, head tech, or MRI safety supervisor. In the case of endoscopic clips, models such as the QuickClip and LongClip devices have been labeled by the manufacturer as unsafe for MRI, whereas the TriClip model earned that designation after experimental detachment from ex vivo gastric tissue in a 1.5-T field [1]. At least 23% of screeners misclassified the safety of one or more MRI-unsafe clips. For safe and efficient endoscopic resection . We created a primary bilingual electronic survey using the FluidSurveys (SurveyMonkey) online survey tool, a web-based electronic survey distribution program. Keywords: contraindications, endoscopy, MRI, organization and administration, questionnaires, surveys. DISCLOSURE: All authors disclosed no financial relationships relevant to this publication. For example, 16% reschedule the MRI examination for more than 6 weeks after endoscopy, despite evidence that some endoscopic clips, like the Resolution Clip model, may remain in the human gut for as long as 33 weeks [4]. 2). U.S. Food and Drug Administration website. The Endo Clip™ II clip applier contains 20 ML titanium clips. The result, rated on a scale of 1–10, was a mean value of 7.9 (range, 2–10). We suggest that future efforts be directed at further testing of endoscopic clip behavior in MRI and at a more systematic and objective search for possible complications. Magnetic resonance imaging safety of surgical clips and staples We read McCall et al.’s letter about the magnetic resonance imaging (MRI) safety of Epilong Soft Epidu-ral Catheters (Pajunk Medizintech-nologie GmBH, Geisingen, Germany) [1] and would like to add further information for readers about the MRI compatibility of surgical clips and staples used in current surgical practice. CONCLUSION. OBJECTIVE. Only one center made changes to their screening protocol between surveys—a nonscreening site that incorporated endoscopic clips into its screening form—bringing the percentage of endoscopic clip screeners in this study to 78% of participants. The study design had limitations. Fifty-three of these (representing 67 centers) completed the primary survey. For many years, endoscopic clips were largely considered safe for MRI, in part owing to their almost universal construction from nonferromagnetic materials, such as tantalum, titanium, and specific types of stainless steel [2], but also because of how soon after placement they were expected to automatically detach from the bowel wall and be eliminated from the body, 1–2 weeks for most endoscopic clips [1]. Sixteen of the 67 participating centers (24%, representing 149,450 estimated annual patient visits) reported not specifically screening for endoscopic clips as part of regular pre-MRI screening (i.e., were nonscreeners). ‡ LIGAMAX 5 Endoscopic Clip Applier provides greater in-jaw clip retention than all other leading 5mm clip appliers to reduce/mitigate clip dislodgement. The modern, high-tech equipment available allows for the most up-to-date procedures (such as Endoscopic Retrograde Cholangio-Pancreatography - ERCP, Spyglass endoscopy, Endoscopic Ultrasound, Double … NHS GGC MRI safety policy states that patients with haemostatic clips i.e. mri any tool can be dangerous if not used properly • “overall, it is an extremly safe procedure, but like all powerful pieces of equipment, there are rules that have to be followed,” dr m nessaiver. In general, most of the endoscopic devices for deploying clips can seal openings from 0.4 inches to 0.5 inches (about 10 to 12 millimeters) across. The radiopaque Resolution Clip is designed for hemostasis, endoscopic marking, closure and anchoring of jejunal feeding tubes. The first two sections of the survey gathered data on the MRI equipment at each site (section 1) and yearly patient visits and examinations (section 2). MRI Fact Sheets. Optimization of Split-Bolus CT Urography: Effect of Differences in Allocation of Contrast Medium and Prolongation of Imaging Delay. Magnetic resonance imaging compatibility of endoclips, American Society for Testing and Materials. Frequently Asked Questions. The reasons provided for not screening were as follows: five (31%) were unaware that some endoscopic clips may not be safe for MRI, four (25%) stated that their local endoscopists use only MRI-safe clips, three (19%) decided not to screen after review by a safety committee, two (13%) tried screening for endoscopic clips but stopped because of limited yield or benefit, and one (6%) reported following the attending radiologist's orders in these matters on a per-case basis. Once collection was complete, an anonymized preliminary copy of the initial results was distributed to all participants in January 2016. The physical deflection and strength of attraction of endoclips: Resolution Clip, TriClip, QuickClip, and Ethicon Endo-surgery Clip were measured in different positions by using an MRI scanner at a field strength of 1.5 Tesla. Last, although several different safety practices were reported for when patients with endoscopic clips undergo MRI, each of these was used by only a small proportion of centers. Clips were selected for testing that represented the largest metallic sizes made from materials with the highest magnetic susceptibilities among 61 other similar implants. Ethics approval was obtained from the University of Saskatchewan Research Ethics Board. All other clips showed deflection in a magnetic field, but only the TriClip demonstrated detachment from gastric tissue, and hence should be considered MRI incompatible. MRI Safety of Two Endoscopic Homeostasis Clips. We thank all of the survey participants for completing the survey, the University of Saskatchewan College of Medicine Dean's Summer Research Program for providing the salary of one of the investigators (F. Accorsi), and the Saskatchewan Office of Francophone Affairs and the Saskatoon Population and Health Office for assistance with the French translation of survey materials. None of the 28 responding centers (representing approximately 157,000 patient visits and 306,000 examinations per year) reported knowledge of any complications due to endoscopic clips in MRI. Data are percentage of centers classifying each clip type with raw numbers in parentheses (n = 48). How many MRI examinations do you perform per year? Endo Clip™ II 10 mm Pistol Grip Single Use Clip Applier. Section 6—Fifty screeners provided data on their protocol for dealing with patients with confirmed gastrointestinal endoscopic clips (Table 1). File: Memo-GI-Clips-9-25-13-final.pdf. To our knowledge, no MRI-related complications of the use of gastrointestinal endoscopic clips or any other type of metal clip, staple, or fastener have been reported in the literature [2]. Implementation of a Point-of-Care Radiologist-Technologist Communication Tool in a Quality Assurance Program, Review. Physical deflection and detachment from pig stomach mucosa in an MRI scanner. A follow-up reminder was sent if a response to the initial invitation was not received after 2–4 weeks. You may not be able to have an MRI while the clip is still in you. It also can be used for hemostasis for prophylactic clipping to reduce the risk of delayed bleeding post lesion resection. The current labeling standard for classifying the MRI safety of implanted medical devices such as endoscopic clips is defined by the U.S. Food and Drug Administration and includes three categories: MRI safe, MRI conditional, and MRI unsafe. The concern is that torqueing of a ferromagnetic hemostasis clip Responses from 50 screeners on the primary survey and three nonscreeners on the secondary survey were combined, and these 53 centers indicated how valuable they considered endoscopic clip screening for their patients.

Endoscopic Clip MRI Screening: A Canada-Wide Policy Survey. It was possible to contact a total of 155 appropriate individuals (representing 194 MRI-equipped centers) by telephone; 103 of those responding (representing 122 centers) agreed to participate and were provided a survey access link. You will be able to rank these in the following section. Section 3—All 51 screeners provided data about how screening is performed: 45 (88%) screened in person, 23 (45%) screened by telephone, six (12%) used screening by the referring physician, and two (4%) screened using mailed-out forms. MRI Safety and Compatibility Information To determine the compatibility of different endoclips with MRI. In total, 18 (36%) centers may, in some circumstances, perform MRI on a patient with confirmed gastrointestinal endoscopic clips: 15 (30%) reported requiring approval and planning by a radiologist before MRI acquisition, nine (18%) limit the field strength to a maximum of 1.5 T, four (8%) image only anatomic regions far away from the known clip, four (8%) try to minimize specific absorption rates, and three (6%) limit the duration of imaging to a maximum of 15 minutes. Specific details, including screening steps, the way in which the presence of different endoscopic clip models affects decision making, and the protocols in place for patients with confirmed gastrointestinal endoscopic clips, were also assessed. Although 11 of these were aware of potential endoscopic clip safety concerns and chose not to screen for reasons discussed previously, five were unaware that endoscopic clips may not be safe for MRI. Please keep the clip identification card. mri safety. Many Canadians are undergoing MRI without screening for endoscopic clips. It is “MR Conditional,” a safety term which indicates that the device has been demonstrated to pose no known hazards in a specified MRI envi- ronment with specified conditions of use. (Leave the check-boxes unchecked if a clip is MRI-unsafe) (Options include: Resolution Clip, Long Clip, QuickClip2, QuickClip2 Long, TriClip, and custom answers), If endoclips are present in the patient for which safety cannot be guaranteed (you are uncertain of clip type, or vendor does not ensure safety of clip), what are your next steps? The development of endoscopic clips heralded a new era for endoscopic therapy. As such, safety information was extrapolated from manufacturer labeling [2], previous research [1, 3, 4], and anecdotal reports from participants. No data are available about the actual magnetic field strength at which endoclips are first deflected nor the clinical relevance of the magnetic fields on endoclips used in GI endoscopy. Participants who did not screen for endoscopic clips, called nonscreeners, bypassed sections 3–7 and were instead asked to complete only one further section regarding their reasons for forgoing this process (section 8). See the MRI Fact Sheets below. Thirty-eight of the 48 (79%) answered affirmatively and subsequently categorized a list of common endoscopic clip models as either MRI safe, MRI conditional, or MRI unsafe (Fig. Endoscopic clips or hemostatic clips are widely used in GI endoscopy to treat bleeds and tissue defects. The Endoscopy Suite has been recently refurbished and updated and is a state-of-the-art unit that provides comfortable single sex facilities for patients undergoing endoscopy procedures. Accordingly, many MRI centers have become aware of endoscopic clip safety concerns, evidenced by the 76–78% of survey participants that specifically screen for endoscopic clips before MRI, 92% of which consider it essential for MRI safety. They need to be accurate. Finally, this study was a survey of current screening practices, not a practical assessment of the safety of these clips in clinical use. Supported by the University of Saskatchewan Dean's Summer Research Program (F. Accorsi). Carilion Clinic; Andrew Y. Wang. Admittedly, endoscopic clip safety is a new and developing field. The overall length of the shaft is approximately 29 cm (11"). This wording was used to capture a broad range of screening scenarios, but it does not tell us how often participants are relying on these steps during screening or under which circumstances. We built a list of potential survey participants using online databases of MRI centers in Quebec (Quebec Health Resource Search) and the rest of Canada (Canadian Institute for Health Information, Selected Medical Imaging Equipment in Canada). All commercially available endoclips are labeled as magnetic resonance imaging (MRI) incompatible. Only the Triclip demonstrated detachment from the pig gastric tissue under testing conditions. The current labeling standard for classifying the MRI safety of implanted medical devices such as endoscopic clips is defined by the U.S. Food and Drug Administration and includes three categories: MRI safe, MRI conditional, and MRI unsafe [5]. Who to Call Digestive Health Center 750 University Row Madison, WI 8 am to 5 pm weekdays (608) 890-5000 or (855) 342-9900 After clinic hours, please call (608) 890-5000. All other clips showed deflection in a magnetic field, but only the TriClip demonstrated detachment from gastric tissue, and hence should be considered MRI incompatible. Section 4—All 51 screeners provided data about specific steps in their endoscopic clip screening protocol (Fig. An American College of Radiology expert panel on MRI safe practices recommends that positive identification of medical implants be made before MRI and that best efforts be made to determine their MRI compatibility [6]. Two centers provided custom response of Instinct Endoscopic Clip model (Cook Medical), which was correctly classified as MRI conditional by both centers. FTRD® - Closing the gap between endoscopy and surgery. 2 —Chart shows safety classification of six common endoscopic clip models as reported by participating centers. By continuing you agree to the use of cookies. Before the current study, however, consistency in screening practices and policies between centers was unknown. Endoclips that demonstrated deflection were attached to a pig stomach and tested for detachment at a 1.5-Tesla MRI field strength. If MRI were to be performed on a patient with a known gastrointestinal endoclip(s), what precautionary steps may you take (select all that apply): Approval and planning by radiologist required before scanning, Consultation with physicists before/during MRI examination, Scan only anatomical regions far away from the known clip, Limit field strength used, please specify, Avoid certain pulse sequences, please specify, Do you have routine follow-up with these patients? Conclusions: The Ethicon Endo-surgery clip is compatible with MRI. A total of three Delphi rounds were held, with 100% response rate for each (Fig. How many MRI scanners of each kind are found at all of the centers that you represent? Although the risks of MRI to patients with endoscopic clips is unclear, the misclassification of some endoscopic clip models and inconsistent protocols for dealing with confirmed endoscopic clips call for further research and unified evidence-based endoscopic clip screening standards. Items in review of past imaging refer to available studies performed after endoscopy. The Ethicon Endo-surgery clip is compatible with MRI. Responses are divided into four categories: verbal interview, chart and imaging review, new imaging, and issues related to timing of MRI. In total, every endoscopic clip model included in the survey, with the exception of the Instinct Endoscopic Clip (Cook Medical) model, was misclassified by at least 13% of respondents, and at least 23% of screeners misclassified the safety of one or more MRI-unsafe clip. For example, in 2009 Gill et al. No centers schedule follow-up appointments with these patients after MRI. (Scale of 1–10, 1 being of least value and 10 of most value), [Author note—Section 8 was shown to only nonscreeners. (Yes/No), Which models do you consider MRI-safe and/or MRI-conditional? • Re-bleeding may occur if the clips detach within 24 hours. In addition, because nonscreeners were initially omitted from section 7 of the primary survey (regarding the perceived value of endoscopic clip screening), they were presented with this section in the secondary. Sites that did screen for endoscopic clips, called screeners, were prompted to complete five further sections regarding specific screening methods (sections 3 and 4), safety considerations for different endoscopic clip models (section 5), protocols for dealing with patients with confirmed endoscopic clips (section 6), and perceived value of endoscopic clip screening (section 7). (Yes/No) [Author note—An answer of “No” branched respondents directly to section 8. The data were analyzed on a per-center basis. ], How is the endoclip screening at your site performed? Section 1—All 67 participating centers provided data on their MRI equipment, among which a combined total of 80 1.5-T systems and 19 3-T systems were located. The magnetic attraction was strongest for the Resolution Clip (0.7 gauss) compared with the TriClip (1.2 gauss) and the QuickClip (26.8 gauss). ASJC Scopus subject areas … Review. May 2017; American Journal of Roentgenology 209(1):1-6 Similarly, six centers (13% of respondents to this section) considered the Resolution Clip model safe for MRI, despite its MRI-conditional classification [2]. Studies have also shown longer than expected endoscopic clip retention times. Sixteen centers (24%) did not specifically screen for endoscopic clips, five because they were not aware that endoscopic clips may not be safe for MRI. Conversely, 10 centers (21%) reported that no endoscopic clip models were considered MRI safe or conditional at their institutions. (Options: 1.5 T, 3 T, and custom magnetic field strengths). CONTOUR ® Curved Cutter Staplers. Additional 10 centers reported that they did not consider any clips MRI safe or conditional, and as such, their response was recorded as MRI unsafe for all clip models. Fingers guide applier for easy clip loading. Fewer centers performed new imaging to search for clips when necessary. Eight (16%) reschedule for more than 6 weeks after endoscopy, and nine (18%) limit the field strength to 1.5 T, the safety of which is uncertain.
