[A new accessory for the isostatic anal retractor]

Area of Science:

• Surgical instrumentation
• Colorectal surgery
• Medical device innovation

Background:

• The isostatic anal retractor is a surgical tool used in treating pelvic and anal pathologies.
• Current limitations may exist in visualizing the operative field with existing retractors.
• Improved visualization is crucial for successful surgical outcomes in anorectal procedures.

Purpose of the Study:

• To introduce and evaluate a novel accessory for the isostatic anal retractor.
• To assess the accessory's efficacy in enhancing operative field visualization.
• To determine the impact of the accessory on patient outcomes and surgical procedures.

Main Methods:

• A new accessory featuring elastic systems was designed for the isostatic anal retractor.
• The accessory attaches to the retractor's metal ring using curved needles and mucosal flaps.
• A cohort of 25 patients (15 mucosal prolapse, 5 hemorrhoids, 5 anal fistulas) were treated using the device.

Main Results:

• 95% of patients experienced improved operative field visualization compared to using the retractor alone.
• No complications were reported related to the use of the retractor or the new accessory.
• The accessory was deemed satisfactory by the surgical team for procedures requiring enhanced visualization.

Conclusions:

• The new accessory, when used with the isostatic anal retractor, effectively enhances surgical field visualization.
• This improved visualization contributes to better therapeutic results and greater operator autonomy.
• The accessory respects sphincter function while improving surgical precision in anorectal surgery.
