An observational study in Perianal Abscess, sponsored by Xi'an Hospital of Traditional Chinese Medicine. Completed at 1 site in China. Open to participants aged 18 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-01-07.
Sponsored by Xi'an Hospital of Traditional Chinese Medicine · Observational
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.
152 studies on the registry are indexed under Abscess; 22 are open to participants now.
This study's enrollment of 100 is close to the median of 100 across 24 observational studies indexed under Abscess.

Volunteers who did not keep the specimens as required
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Control group: ① Age between 18-60 years, permanent residents in Xi'an; ② had no serious chronic disease, no abnormality in physical examination in the last 1 week; ③ did not use drugs that may affect intestinal flora in the last one month; ④ himself and his family members are willing to participate in the study and sign the informed consent.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

This group will collect rectal secretions and stool samples and pus samples from patients with perianal abscess before treatment, and collect rectal secretions and stool samples from patients again 2 months after treatment according to the diagnosis and treatment guidelines.
Procedure: surgical operation
This group collected rectal secretions and stool specimens from a healthy population.
