Summary
Anorectal abscess and fistula management remains understudied in randomized trials. This review focuses on existing evidence for abscess treatment and fistula repair, highlighting knowledge gaps for future research.
Area of Science:
- Gastroenterology
- Colorectal Surgery
Background:
- Anorectal abscess and fistula share anatomical, etiological, and morbidity connections.
- Despite extensive descriptions, randomized controlled trials (RCTs) are scarce.
Purpose of the Study:
- To review existing RCTs on anorectal abscess and fistula management.
- To identify gaps in current knowledge and suggest future research directions.
Main Methods:
- Literature review of randomized controlled trials.
- Focus on trials concerning primary abscess suture, simultaneous abscess drainage and fistulotomy, and comparisons between fistulotomy and fistulectomy.
Main Results:
- Limited RCTs exist for these common conditions.
- Evidence is sparse regarding optimal surgical strategies for fistula treatment post-abscess drainage.
Conclusions:
- Further high-quality randomized trials are needed to establish best practices.
- Key areas for future research include primary abscess closure techniques and comparative analyses of fistula surgical procedures.
