Ultrasonic fragmentation. A new technique for mucosal proctectomy

Area of Science:

• Colorectal Surgery
• Gastroenterology
• Minimally Invasive Procedures

Background:

• Standard mucosal proctectomy involves manual separation of rectal layers, which can be challenging in certain conditions.
• Conditions like severe ulcerative colitis and radiation proctitis can complicate rectal mucosal dissection.

Purpose of the Study:

• To introduce and evaluate a new technique for mucosal proctectomy using ultrasonic fragmentation.
• To assess the efficacy and safety of ultrasonic mucosal proctectomy in patients with difficult-to-separate rectal mucosa.

Main Methods:

• Mucosal proctectomy was performed using ultrasonic fragmentation of the rectal mucosa in four patients.
• Three patients had severe ulcerative colitis, and one had radiation proctitis with a rectal stricture.
• An endorectal pullthrough with anastomosis to the dentate line was completed in all cases.

Main Results:

• The ultrasonic mucosal proctectomy technique was successfully applied in all four patients.
• All patients demonstrated uncomplicated healing, with no instances of infection or retraction.
• The procedure was particularly useful in patients where manual separation of the rectal mucosal layer proved difficult.

Conclusions:

• Ultrasonic fragmentation is a viable alternative technique for mucosal proctectomy.
• This method simplifies the procedure in cases where traditional mucosal separation is challenging.
• The technique shows promise for improved outcomes in specific patient populations undergoing rectal surgery.
