Standards for anal sphincter replacement

Area of Science:

• Surgical innovation in proctology and reconstructive surgery.
• Gastroenterology and colorectal surgery advancements.

Background:

• Severe fecal incontinence and the need for abdominoperineal resection present significant challenges.
• Existing treatment options for these conditions are often limited or ineffective.

Purpose of the Study:

• To review the current status of anal sphincter replacement techniques.
• To establish a consensus on the current use of anal sphincter replacement.
• To propose future directions for the development of anal sphincter replacement.

Main Methods:

• A working party identified key areas: indications, scoring, quality of life, therapy choice, and technology dissemination.
• A questionnaire was developed and distributed to working party members.
• The results informed the development of this consensus document.

Main Results:

• Electrically stimulated skeletal muscle neosphincter and artificial anal sphincter are viable options for end-stage fecal incontinence.
• Neosphincters are also suitable for reconstruction post-anorectal excision.
• Strict sterile technique, antibiotics, and DVT prophylaxis are crucial for complication avoidance.
• A standardized scoring system for continence and evacuation is proposed.
• Quality of life assessment using a specific instrument is recommended.
• Controlled dissemination ensures surgeon training and optimal outcomes.

Conclusions:

• Anal sphincter replacement offers a continent solution for end-stage fecal incontinence and post-abdominoperineal resection.
• The developed guidelines aim to promote the safe and controlled adoption of these novel techniques.
