Our Summary
This research paper discusses the use of a specific type of medical imaging, called three-dimensional endoanal ultrasound (3D EAUS), to monitor the treatment of anal fistulas using a method called an anal fistula plug (AFP). An anal fistula is a small tunnel that develops between the end of the bowel and the skin near the anus, a condition often associated with Crohn’s disease and other inflammatory bowel diseases. An AFP is a treatment that involves plugging the fistula to encourage it to heal.
The researchers conducted a retrospective analysis on patients who had undergone AFP treatment between May 2006 and October 2009, and were monitored using 3D EAUS. They looked at ultrasound findings at different points in time after surgery (2 weeks, 3 months, and 6-12 months), and also considered any clinical symptoms reported by the patients.
They found that, in some cases, the 3D EAUS images could predict whether the AFP treatment would fail in the long term. This was particularly true when the ultrasound findings were combined with certain clinical symptoms, such as fluid discharge. For example, if the ultrasound showed gas in the fistula, or if the fistula was still visible 3 months after surgery, this was a strong indicator of treatment failure.
In conclusion, the study suggests that 3D EAUS could be a useful tool for monitoring patients after AFP treatment, and could help to predict whether the treatment is likely to be successful in the long term.

Doctor’s Tip
A helpful tip a doctor might give a patient about anal fistula surgery is to follow up regularly with your healthcare provider and discuss any symptoms or concerns you may have. Monitoring with imaging techniques like 3D EAUS can help assess the success of the treatment and identify any potential issues early on. It’s important to communicate openly with your doctor to ensure the best possible outcome from the surgery.
Suitable For
Patients who are typically recommended anal fistula surgery include those who have recurrent or complex anal fistulas that have not responded to conservative treatments such as antibiotics or drainage procedures. Patients with Crohn’s disease or other inflammatory bowel diseases are also often candidates for anal fistula surgery, as these conditions are known to be associated with the development of anal fistulas. Additionally, patients who are experiencing symptoms such as pain, swelling, or drainage from the fistula may be recommended for surgery to alleviate their symptoms and prevent further complications. Ultimately, the decision to undergo anal fistula surgery is made on a case-by-case basis by a healthcare provider after a thorough evaluation of the patient’s symptoms and medical history.
Timeline
Before anal fistula surgery, a patient may experience symptoms such as pain, swelling, and discharge from the fistula. The patient may undergo various diagnostic tests, such as a physical examination, imaging studies, and possibly a colonoscopy, to determine the extent of the fistula and plan for surgery.
After anal fistula surgery, the patient will typically experience some pain and discomfort in the days following the procedure. They may also have a surgical drain in place to help remove excess fluid from the surgical site. The patient will need to follow post-operative care instructions, such as keeping the area clean and dry, taking prescribed medications, and avoiding certain activities that may irritate the surgical site.
In the weeks and months following anal fistula surgery, the patient will attend follow-up appointments with their healthcare provider to monitor the healing process. This may involve imaging studies, such as 3D EAUS, to assess the success of the surgery and determine if any further treatment is needed. The patient may also be advised to make lifestyle changes, such as dietary modifications or changes in bowel habits, to help prevent recurrence of the fistula.
Overall, the timeline of a patient’s experience before and after anal fistula surgery involves a combination of diagnostic tests, surgical intervention, post-operative care, and ongoing monitoring to ensure successful treatment and prevent complications.
