What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study will observe 90 adults with anal fistulas to see if the time between first symptoms and surgery affects healing and recurrence. Participants are grouped by how long they waited: 3 months or less, 3 to 6 months, or more than 6 months. Researchers will track healing, recurrence, complications, and quality of life for 12 months after surgery. The goal is to find the optimal timing for surgery to improve outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors and patients decide the best time to have anal fistula surgery, potentially improving healing and reducing the chance of the fistula coming back.
What could go wrong
This is an observational study, not a treatment trial. It will only show a link, not prove that timing causes better outcomes. Results may not apply to all patients or fistula types.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of adult patients (aged 18 years or older) who are diagnosed with primary cryptoglandular anal fistula. Diagnosis must be confirmed by clinical examination and preoperative MRI. These patients will be undergoing definitive surgical intervention at the Department of Surgery in Assiut University Hospital between 2026 and 2028. The population excludes pregnant women, individuals with recurrent fistulas or prior surgical intervention for the same fistula, and those whose fistulas are due to specific conditions like Crohn's disease, tuberculosis, malignancy, trauma, radiation, or obstetrical injury.

Inclusion Criteria: * Patients aged 18 years or older diagnosed with primary cryptoglandular anal fistula confirmed by clinical examination and preoperative imaging (MRI). * Patients who will be undergoing definitive surgical intervention for anal fistula at Assiut University Hospital between 2026 and 2028. * Complete medical records available, including documented symptom onset date (defined as first reported perianal pain, swelling, or discharge) and surgery date. * Minimum postoperative follow-up of 12 months, with clinical assessment data on healing and recurrence. Exclusion Criteria: * Fistulas due to Crohn's disease, tuberculosis, malignancy, trauma, radiation, or obstetrical injury. * Pregnant women. * Recurrent anal fistulas or those with prior surgical intervention for the same fistula. * Incomplete records or loss to follow-up before 6 months postoperatively. * Patients with comorbidities precluding surgery (e.g., uncontrolled coagulopathy or active systemic infection).
