Perianal abscess/fistula disease

Area of Science:

• Gastroenterology and Hepatology
• Surgical Anatomy
• Proctology

Background:

• Perirectal abscesses (acute) and fistulas (chronic) originate from infected anal glands.
• These conditions have historically presented diagnostic and management challenges for clinicians.
• Understanding the underlying anatomy and pathophysiology is crucial for effective treatment.

Purpose of the Study:

• To emphasize the critical role of anatomical and pathophysiological knowledge in diagnosing and managing perirectal abscesses and fistulas.
• To highlight the complexities in fistula management, particularly balancing healing rates with fecal continence.
• To review available surgical techniques for fistula-in-ano and stress the importance of patient and technique selection.

Main Methods:

• Review of the pathophysiology of infected anal glands leading to abscess and fistula formation.
• Analysis of standard surgical approaches for perirectal abscess treatment (incision and drainage).
• Discussion of various surgical techniques for fistula-in-ano, focusing on patient selection and outcome optimization.

Main Results:

• Abscess management typically involves straightforward incision and drainage.
• Fistula management is complex, necessitating a balance between healing success and preservation of fecal continence.
• Multiple surgical techniques exist for fistula-in-ano, with no single method universally applicable.

Conclusions:

• Optimal diagnosis and management of perirectal abscesses and fistulas depend on a thorough understanding of anatomy and pathophysiology.
• Successful fistula treatment requires careful consideration of surgical technique tailored to individual patient needs and fistula characteristics.
• Appropriate patient selection and surgical technique choice are key to achieving high success rates and minimizing morbidity in fistula repair.
