Retrospective study comparing rectal endoscopic submucosal dissection with and without Foley catheter drainage tube...

Area of Science:

• Gastroenterology
• Surgical Innovation
• Minimally Invasive Procedures

Background:

• Endoscopic submucosal dissection (ESD) is effective for rectal tumors but challenging for novices due to maintaining a clear surgical field.
• Ensuring procedural efficiency and safety is paramount, especially for less experienced endoscopists.

Purpose of the Study:

• To evaluate the impact of continuous Foley catheter drainage on the efficiency and safety of rectal ESD performed by novice endoscopists.
• To determine if Foley catheter use enhances dissection speed and reduces adverse events.

Main Methods:

• Retrospective study of 26 patients undergoing rectal ESD by novice endoscopists under expert supervision.
• Patients divided into two groups: Foley catheter drainage (n=12) and no catheter (n=14).
• Key outcomes included dissection speed, procedure time, R0 resection rates, and adverse events.

Main Results:

• Dissection speed was significantly higher in the Foley catheter group (18.6 mm²/min) compared to the non-catheter group (10.5 mm²/min, P=0.027).
• Lower total procedure time and sodium hyaluronate usage were observed in the catheter group, but not statistically significant.
• No adverse events were reported in either group.

Conclusions:

• Foley catheter placement significantly improves rectal ESD efficiency in novice endoscopists by increasing dissection speed.
• This technique shows potential for safer and more effective rectal ESD procedures.
• Larger studies are warranted to confirm these findings and assess broader benefits.
