The Study
Pathophysiological mechanisms and clinical management of type 2 diabetes mellitus complicated with anal fistula
This study is like a summary of many different doctors' stories about how they treat diabetes and fistulas, but it didn't do any new experiments. So we can't say for sure that one treatment causes better healing—we just know some doctors tried it and saw good results.
Analysis score
Maximum 5 for a narrative review.
Where the score came from
People with diabetes have a much harder time healing after surgery for a painful anal hole because high sugar messes up their blood, immune system, and healing cells.

Systematic reviews and meta-analyses of cohort studies. They sit above a single cohort study but below a single randomized trial, because the underlying evidence is still observational.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — better blood sugar control and modern surgeries mean fewer infections, less pain, and better quality of life for diabetic patients.
- 2Diabetics are 2x more likely to get the hole; 87.6% heal with TROPIS surgery; 68–85% heal with their own stem cells; infection drops to 8.2% if HbA1c is under 7.0%; one weekly insulin shot works better than daily ones.

Changes in the body's metabolic state directly affect how microbial infections and biofilms form.
Diabetic patients with anal fistula experience delayed wound healing and higher rates of recurrence compared to non-diabetic patients, due to reduced blood flow to the tissue and ongoing inflammation.
In diabetic patients with complex anal fistulas, treatment using stem cells from the patient's own body results in healing rates between 68.4% and 84.6%, and is safer and easier to perform than stem cell treatments from donors, which have not been proven effective for this condition.
Diabetic patients having surgery for an anal fistula with blood sugar levels below 7.0% before surgery have an 8.2% chance of developing a postoperative infection. Patients with blood sugar levels of 7.0% or higher have a higher infection rate.
In diabetic patients with anal fistula, TROPIS surgery results in an 87.6% healing rate over the long term and carries less than a 5% risk of anal incontinence, which is better than traditional surgical removal methods.
Diabetic patients undergoing anal fistula surgery who receive once-weekly insulin icodec have better adherence to their insulin regimen and more stable blood sugar levels during surgery compared to those receiving daily insulin.
