Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Safety and effectiveness of a new hemostatic system to prevent delayed bleeding after endoscopic resection in a selected high-risk population (NEXPOWDER- ENDOHS).

Indication:

Patients with indication of endoscopy resection by endoscopic mucal resection (EMR) or endoscopic submucosal dissection (ESD) with high risk of delayed bleeding (≥5%).

Hypotheses:

The use of NexpowderTM after upper and lower gastrointestinal ESD or EMR of ≥20mm in high-risk population will prevent and decrease delayed bleeding to less than 5%.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Hypotheses:

The use of NexpowderTM after upper and lower gastrointestinal ESD or EMR of ≥20mm in high-risk population will prevent and decrease delayed bleeding to less than 5%.

Study design:

This is an investigator-initiated, multicentric, international, open-label, non-controlled, prospective study:

* All subjects with indications undergo screening and baseline visit,
* Informed consent is obtained when scheduling the ESD or EMR procedure,
* ESD or EMR is performed, at the end of resection, NexpowderTM is applied on the resected field,
* A follow up visit is scheduled at 4 weeks.

Endpoints:

* Primary:
* Assess the delayed bleeding rate after ESD or EMR of ≥20mm in a selected high-risk population when using NexpowderTM at the end of the procedure.

This hypothesis is that the use of NexpowderTM will reduce the rate of DB from 16% (reported rate in the literature) to less than 5% (excepted observed rate during the study).

* Secondary:
* Safety of NexpowderTM endoscopic hemostasis system,
* Procedure duration and NexpowderTM spaying duration,
* Length of stay in hospital,
* Post intervention pain,
* Adverse events related to the use of NexpowderTM:
* Per procedural
* Early (up to controlled endoscopy or at 24hours post procedure)
* Late (up to 4 weeks follow-up).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Age: ≥18 year of age at the time of informed consent,
* Patients must have given written informed consent,
* Subjects with documented lesions with indication of upper or lower endoscopic removal by ESD or EMR with high risk of delayed bleeding (+/-16%), namely:
* All patients under anticoagulation (vitamin K antagonist, direct anticoagulant, non-fractionated heparin or low molecular weight heparin) or anti-aggregating (P2Y12 receptor antagonists),
* Patients without anticoagulation or anti-aggregating with indication of duodenal EMR or ESD (if duodenal cold snare EMR: only under anticoagulant or P2Y12 receptor antagonist),
* Resection field of ESD or EMR is ≥ 20mm (same size restriction in case of endoscopic papillectomy).

Exclusion Criteria

* Resection bed \<20mm,
* Subject currently enrolled in another interventional confounding research (no contra-indication for image or blood collection in another protocol),
* Incapacitated subjects, pregnant or lactating women.
