Advancements in injection materials for submucosal lifting in endoscopic interventions

Area of Science:

• Gastroenterology
• Biomaterials Science
• Surgical Innovation

Background:

• Endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) utilize submucosal injection cushions to create a safe operative field.
• These cushions enhance lesion separation from the muscularis propria, improving resection precision and reducing complications.

Purpose of the Study:

• To comprehensively evaluate current and emerging submucosal injection materials for gastrointestinal endoscopic procedures.
• To assess the mechanical performance, biocompatibility, and intraoperative usability of these materials.
• To identify translational hurdles and propose strategies for wider clinical adoption.

Main Methods:

• Comparative analysis of conventional and novel functionalized submucosal injection agents.
• Evaluation of material properties including mechanical performance, biocompatibility, and injectability.
• Review of manufacturing, supply chain, clinical, and reimbursement factors.

Main Results:

• Despite advancements, limitations in injectability, biocompatibility, multifunctionality, and evidence hinder widespread clinical use.
• Key barriers identified include manufacturing constraints and lack of robust clinical and reimbursement data.
• Emerging materials show promise but require further validation.

Conclusions:

• Bridging the gap between innovative submucosal injection materials and clinical practice necessitates addressing injectability, biocompatibility, and multifunctionality.
• Standardized protocols, regulatory engagement, optimized production, and clinical/economic analyses are crucial.
• Coordinated efforts across research, industry, and policy are essential for successful translation.
