What is an Aortoenteric fistula?

An aortoenteric fistula is a rare and potentially lethal complication of aortic surgery, which needs surgical intervention once it occurs. Abdominal pain and hematemesis are among the initial symptoms.

What causes aortoenteric fistula repair?

An AEF is an abnormal connection between your GI tract and aorta. Your aorta is the largest artery in your body. It carries blood throughout your body from your heart. Your duodenum or the upper portion of your small intestine is most often affected in your GI system.

Either a primary or secondary AEF may be present. Primary fistulas occur less frequently. These arise from the direct friction and irritation of your aorta. Included among the root factors are the following:

• Most common are aortic aneurysms.
• Foreign objects in your organs.
• Radiation therapy.
• Infections like syphilis and TB.

Secondary AEFs present after aortic surgery, usually after synthetic graft treatment of abdominal aneurysms. Open repair of the aortic artery has a higher risk of fistula development than endovascular repair. The patients with AEFs are predominantly male.

Which symptoms are brought on by an aortoenteric fistula?

Massive, difficult to control GI bleeding that can cause shock and even death is a common presentation for AEFs.

Additional indications and manifestations include:

• Low BP
• Abrupt and severe stomach discomfort
• Hematemesis (Blood in vomit)
• Pulsating abdominal mass

What aortoenteric fistula complications could arise?

The following are possible side effects of the fistula or fistula treatment:

• Trauma
• Multiple organ dysfunction
• Cardiac arrest.
• Aortic rupture.
• Fecal incontinence from your fistula.

When is an aortoenteric fistula diagnosed by a doctor?

When a physician suspects AEF, they will not carry out further tests and will proceed to surgery. About two-thirds of diagnoses are made in the operating room. Many diagnoses aren't made until the autopsy report is published after the death of a person.

If you never had an aortic aneurysm or aortic surgical repair in the past, your doctor may have to run further tests before suspecting an AEF. Tests may include:

• CT (Computerized Tomography) Angiography
• Upper esophagogastroduodenoscopy (EGD)
• Ultrasound

How do doctors repair an aortoenteric fistula?

AEFs should be given prompt treatment to avoid potentially deadly complications. Surgeons have a choice of using the open technique, the common traditional approach, or the less invasive endovascular procedure.

Objective for surgery include:

• To stop the bleeding
• Confirm the diagnosis
• To reconstruct the aortic segment that is injured.

Open Surgery

Your doctor will cut a long incision through your abdomen to expose your aorta during an open repair. They will then fix the fistula. They may also need to remove dead or contaminated tissue, which sometimes includes the graft from a previous surgery.

Open surgery has been correlated with a lowered incidence of sepsis or postoperative infection for those patients who are healthy enough to tolerate the additional stress of the surgery.

Endovascular repair

Your doctors enter your blood vessel from within to access your aorta to do endovascular surgery. Your surgeon, using specific instruments, will make an incision across one of your arteries, normally in your groin and implant a long, thin tube that will eventually end up in your aorta. The tube used to operate on your fistula will be implanted.

It is generally recommended that endovascular repair be implemented for individuals with primary AEFs who do not manifest symptoms of infection. This is the usual method doctors use to stabilize critically ill patients with secondary AEFs or patients who cannot undergo open surgery because they are not doing well.

What is a patient's prognosis following aortoenteric fistula repair?

Repairs of AEF can be lifesaving. Without surgical intervention, the chance of dying is almost 100% among someone with an AEF.

Is aortoenteric fistula painful?

One of the most common symptoms of AEF is abdominal pain. It is one of the first signs reported by more than half of the patients with AEF. It can be sudden in onset and extremely sharp.

How long is recovery after aortoenteric fistula repair?

Recovery from aortic surgery can take weeks or months. The recovery period after open abdominal aortic aneurysm surgery is typically 6–12 weeks.
