About this study
The goal of this observational study is tolearn the association of gut microflora with the onset of perianal abscesses. The main questions it aims to answer are:
Question 1: To understand the structure of rectal microbial community composition and its relationship with pathogenic bacteria in patients with perianal abscess.
Question 2: Understand the structure of rectal microbial community composition in healthy people.
Participants will be collected with rectal secretions and stool specimens.In addition, patients with perianal abscess should also collect pus samples.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Observation group: the structure and changes of rectal flora before and after treatment (time frame: Two months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2025; AzTrials last refreshed its copy on 8 Nov 2026.
