Colorectal endoscopic submucosal dissection using novel articulating devices: a comparative study in a live porcine...

Area of Science:

• Gastroenterology
• Surgical Innovation
• Endoscopic Procedures

Background:

• Colonic endoscopic submucosal dissection (ESD) is a complex procedure.
• Current ESD methods are associated with significant time requirements and a high risk of complications, such as perforation.
• There is a need for improved techniques to enhance safety and efficiency.

Purpose of the Study:

• To compare the safety and efficacy of novel articulating devices versus conventional methods for colonic ESD.
• To evaluate the impact of new devices on procedure time and adverse events.
• To assess the potential for reduced muscular layer damage with articulating devices.

Main Methods:

• The study utilized a live porcine colon model for comparison.
• Thirty colonic endoscopic submucosal dissections (ESDs) were performed, with 15 using conventional methods and 15 using novel articulating devices.
• Key metrics recorded included procedure time, adverse events (perforation, bleeding), and muscular layer damage.

Main Results:

• The novel articulating devices demonstrated a 0.0% perforation rate, compared to 6.7% with conventional ESD.
• Significantly less muscular layer damage was observed with the new method (6 sites vs. 37 sites, P=0.024).
• The mean procedure time per unit area was significantly shorter using the articulating devices (4.6 min/cm² vs. 7.0 min/cm², P=0.042).

Conclusions:

• Novel articulating devices offer a safer alternative for colonic ESD, significantly reducing perforation rates.
• These devices lead to a substantial decrease in muscular layer damage.
• The use of articulating devices shortens resection time, improving the overall efficiency of colonic ESD procedures.
