    A Comparison of Eleview Versus Hetastarch as Injectate for EMR

    NCT03350217

    9 Oct 2017 to 7 Jan 2019

Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

EMR is a technique used for the removal of flat or sessile neoplasms confined to the superficial layers of the GI tract using a snare. Injection-assisted EMR is commonly used during resections of larger flat lesions as it provides submucosal lift of polyps, adenomas, other gastrointestinal mucosal lesions or early-stage cancers prior to EMR. This has been found to minimize mechanical or electrocautery damage to the deep layers of the gastrointestinal tract wall as the injectate provides a "safety cushion" as such between the area to be removed and healthy mucosal tissue. Several solutions are used today for injecting lesions including saline, hyaluronic acid, and hydroxyethyl starch (Hetastarch). Saline solution has been found to dissipate within minutes, which may result in a lower quality lesion lift. Hyaluronic acid provides a longer lift, but is expensive and is not readily available in the U.S. A new injectate known as Eleview has been developed for use in gastrointestinal endoscopic procedures and recently approved by the FDA. This injectate boasts a cushion of excellent height and duration through the use of an oil-in-water emulsion. However, the initial cost of this material is quite high ($80 per 10 ml). Hetastarch, which is the current injectate used by Dr Rex, is a safe and considerably inexpensive solution that provides prolonged submucosal elevation and lowers procedure times. Our study will aim to compare Eleview to Hetastarch in the hopes of finding the ideal submucosal injectate. This trial will focus on polyps of size ≥11 mm removed by snare EMR technique. Patients with lesions deemed not suitable for EMR due to features suggestive of sub-mucosal invasion will not be included.

Primary outcomes1

Outcomes the sponsor listed as primary.

  1. Sydney Resection Quotient (SRQ)

    Time frame · During the large polyp removal

    Registry description

    Comparison of the Sydney Resection Quotient between EMRs done using Eleview vs EMRs done using Hetastartch as the injection fluid. The Sydney Resection Quotient (SRQ) is the size of the polyp divided by the number of pieces in which the polyp was resected. A larger SRQ is better than a smaller SRQ.

Secondary outcomes(12)
  1. Injected Volume Needed for Initial Lesion Lift

    Time frame · During initial injection portion of large polyp removal

    Registry description

    Comparison of the volume of injection fluid needed for initial lesion lift of Eleview vs Hetastarch.

  2. Injected Volume Needed for Complete Removal of Lesion

    Time frame · During the large polyp removal

    Registry description

    Comparison of the volume of injection fluid needed for complete removal of lesion between Eleview and Hetastarch

  3. Number of Re-injections Needed During Resection

    Time frame · During the large polyp removal

    Registry description

    Comparison of the number of re-injections needed during the large polyp removal. Number of re-injections is the number of times the injection device is passed down the scope to inject the polyp after initial injection during the large polyp resection.

  4. Number of En Bloc Resections

    Time frame · During the large polyp removal

    Registry description

    Comparison of the number of polyps that were able to be removed in one piece during the resection between polyps injected with Eleview and polyps injected with Hetastarch

  5. Number of Pieces Resected Using Snares

    Time frame · During the large polyp removal

    Registry description

    Comparison of the number of pieces removed using snare between polyps injected with Eleview compared with polyps injected with Hetastarch.

  6. Mound Concentration Diameter

    Time frame · During the large polyp removal

    Registry description

    Comparison fluid behavior and ease of use between Eleview and Hetastarch rated on a 3-point scale (Excellent, Sufficient, or Inadequate). The more the fluid spread out laterally after being injected, the worse the rating would be. The more the fluid stayed concentrated around the polyp after injection, the better the rating would be.

  7. Mound Concentration Height

    Time frame · During the large polyp removal

    Registry description

    Comparison of how well the injection fluid lifted the polyp during the large polyp removal between Eleview and Hetastarch rated by the following scale: Excellent, Sufficient, Inadequate. The more the polyp was able to be lifted vertically, the better the rating would be.

  8. Mound Duration

    Time frame · During the large polyp removal

    Registry description

    Comparison of how long the injection fluid was able to keep the polyp lifted during the large polyp removal between Eleview and Hetastarch. This was rating using the following scale: Excellent, Sufficient, or Inadequate. The longer the injection fluid stayed concentrated and kept the polyp lifted, the better rating it received while rapid dissipation of the fluid would receive a worse rating.

  9. Ease of Injection

    Time frame · During the large polyp removal

    Registry description

    Comparison of how easily the fluid was able to be injected. This was rated by the endoscopy technician assisting in the large polyp removal. It was rated on the following scale: Very Easy, Easy, Difficult, Very Difficult.

  10. Need for Additional Treatments Relating to the Polyp Resection Such as Avulsion, Coagulation or Ablation.

    Time frame · During the large polyp removal

    Registry description

    Need for additional treatments relating to the polyp resection such as avulsion, coagulation or ablation. These treatments can be done in addition to endoscopic mucosal resection (EMR) in order to remove polyp tissue/treat the defect.

  11. Time Required to Remove the Lesion

    Time frame · During the large polyp removal

    Registry description

    Time (in minutes) to remove the lesion completely (measured from the first injection to final excision of the lesion)

  12. Safety Outcomes as Assessed by Complications During or After the Procedure

    Time frame · during large polyp removal through 30 days post procedure

    Registry description

    To evaluate the safety of Eleview for EMR procedures in relation to adverse events and occurrence of complications during and after the EMR procedure in comparison to Hetastarch injectate.
