Endoscopic suturing and clipping devices for defects in the GI tract

Area of Science:

• Gastroenterology
• Endoscopic Surgery
• Medical Device Technology

Background:

• Gastrointestinal (GI) luminal defects (perforations, leaks, fistulae) present challenges in endoscopic interventions.
• Current endoscopic tissue apposition techniques include through-the-scope clipping (TTSC), over-the-scope clipping (OTSC), and suturing.
• Lack of clear guidelines due to defect heterogeneity and device-specific factors necessitates evidence-based recommendations.

Purpose of the Study:

• To review existing evidence on endoscopic tissue apposition devices.
• To delineate the specific indications and roles for each device in GI defect closure.
• To provide a foundation for evidence-based practice in endoscopic tissue apposition.

Main Methods:

• Systematic review of literature on endoscopic tissue apposition devices.
• Analysis of studies reporting on TTSC, OTSC, and suturing techniques.
• Evaluation of data regarding defect characteristics, device performance, and outcomes.

Main Results:

• TTSC, OTSC, and suturing have distinct applications based on defect size, depth, and location.
• Device selection is influenced by anatomical site within the GI tract and defect complexity.
• Evidence suggests varying success rates and complication profiles for different devices and indications.

Conclusions:

• Optimal endoscopic closure of GI defects requires careful consideration of device-specific capabilities.
• Further research is needed to standardize recommendations for tissue apposition techniques.
• This review aims to guide endoscopists in selecting the most appropriate device for specific gastrointestinal luminal defects.
