Fistula

What is a Fistula?

The term fistula describes an abnormal connection between two parts of the body. For example, a fistula may occur between an organ and another body part.

There are several types of fistulas:

  • Blind: A fistula that is only opened on one end, but is connected to two body structures.
  • Complete: This type of fistula has an opening outside the body, as well as inside the body.
  • Horseshoe: This type of fistula is between the anus and the surface of the skin, and it goes around the rectum.
  • Incomplete: An incomplete fistula is a tube that begins at the skin but is closed on the inside, so it does not connect with any body structures internally.

There are various possible locations of a fistula on the body. Some common fistula locations include:

  • Between arteries and veins
  • From bile ducts to the skin’s surface, due to gallbladder surgery
  • Between the neck and throat
  • From the cervix or bowel to the vagina
  • From the colon to the body’s surface
  • In the area inside the skull and nasal sinus
  • Between the stomach and the skin’s surface
  • From the navel to the gut
  • Between the uterus and the walls of the abdomen

It is also possible to have an anal fistula, which develops when the anus has an abnormal connection with another organ.

Another type of fistula, called a gastrointestinal fistula, is located in the digestive tract. This type of fistula may develop between one part of an intestine and another.

Applicable Procedures

Colonoscopy

What causes a fistula?

There are several causes of a fistula. For instance, injuries and surgery are potential causes. Other fistula causes include infections and inflammation. Fistulas can develop between arteries and veins as a result of an injury, whereas inflammatory bowel diseases, such as ulcerative colitis, can cause the development of fistulas between intestinal loops. An anal fistula can sometimes be congenital, meaning that it is present from the time a person is born. It occurs when an abnormal connection develops between the anus and another organ.

How is a fistula treated?

Treatment for a fistula begins with a diagnosis. A doctor may diagnose a fistula by running blood tests, taking x-rays, or performing an endoscopy or CT scan. Fistula treatments will vary based upon the type and location of the fistula, and in some cases, a fistula may resolve on its own. Fistula treatments may involve managing infection, replenishing fluids, and correcting electrolyte imbalances. In some cases, a fistula may require surgery.

Do I have to seek treatment for a fistula?

If you think you may be suffering from a fistula, it is important to see a doctor to prevent complications. A medical professional can determine the best fistula treatment for your situation.

Common Symptoms

  • “I developed a fever accompanied by stomach pain.”
  • “I started to have diarrhea all the time, and I was suffering from rectal bleeding.”
  • “I felt dehydrated and started to lose weight, and my overall health just got worse.”

I recently had two procedures on June 26th, 2025. Upon arriving at the office, the staff was friendly and helpful. Check-in was seamless, and I barely waited before being called. The team efficiently gathered my information and assured me I’d be seen shortly. Within five minutes, I was in a room.

The nurse and CRNA gathered more information and then the CRNA promptly wheeled me to the procedure room. Both the assistant and doctor were already there, ready and kind. The CRNA and assistant quickly got me all set up, and before I knew it, I was awake and ready to go.

A kind staff member even escorted me to my car afterward. Overall, it was a 5-star experience!
Ceci G.
Staff very knowledgeable. Dr. Bakken always take time to talk to you and doesn't make you feel rushed.
Eric P.
The staff was very helpful and caring made me feel comfortable about my procedure.
Dawn N.
I love love this office and the staff. I personally have been a patient of Dr. Emin Donat since my early 20's. I am now turning 50 this September. He is so kind and caring. His patients are priority. He is so kind. Willing to listen and address your problems. He never makes you feel like he needs to rush onto the next patient. If you need to have any Gi issues addressed go see my friends at the Center For Digestive Health. Anyone of the Doctors are amazing.
John D.
Information provided in advance was excellent and helpful. Follow up notifications were well done and appropriately timed. Staff was very helpful upon arrival and wait time was minimal. Upon entering prep room everything was explained and questions on medicine taken and background was efficiently asked and processed. Doctor Willie explained everything prior to treatment and afterwards. All nurses and assistances were polite, efficient and informative. For the first colon screening that scared me, it was a very positive experience and I am very grateful to the entire staff and doctors at the facility. Thank you, best wishes to all. John

Sridhar V.
I really like the care in this facility. Dr Nandi and the team is awesome !!
George K.
I had a procedure this morning with Dr. Nandi at the Surgical Centers of Michigan located on Investment Drive. Dr. Nandi as always was the most professional and caring doctor that I have encountered.
But, what impressed me was the staff in the office. The TEAM (receptionist, the nurse who checked me and made me ready for the procedure, Anesthesiologist and nurse in the procedure room, the recovery room nurse, the PA who called me later in the day to check-up on me) showed me such care and compassion. It made me feel as if I was the most important patient that they would encounter.
It is obvious that these professionals love what they are doing. They love helping others. That made all the difference to me.
Thank you.
K K

If I could give “10” stars I definitely would
FrannyJ J.
First I would like to say, staff was very friendly !! Dr. Donat was extremely nice and receptive. He listened and asked the right questions to describe my issues. I have had my problem for sometime now and I was VERY afraid of the procedure to diagnose my issues. DR. Donat made me feel comfortable and eased my fear. Not to mention my wait time was minimal.
Sean B.
Dr. Wille and his NP’s are Top Notch with regards to taking care of my gastrointestinal issues. I’ll be honest, I did have a bad experience with another Dr in the group and will never see him again.
Regarding Dr. Wille, he was my father’s GI doc and helped him live some 20 years after his colon cancer. As for me, I’m in my early 60’s and Dr. Wille is well aware of my family history, taking great care of me and has a great bedside manner.
I met Nicolette this week for the 1st time and she was easy to talk to (even if it is/was a difficult conversation).
Andy M.
Great experience at this facility. Staff and Dr. Donat were very professional.
Dan S.
My wife received the utmost in care. Staff was incredible from the reception desk, to the nurses doing the prepping and post care. Thank You to a very caring doctor - Dr. Wille. He met her with a smile which put her at ease quickly, explained the process, performed the procedure, met with me immediately after and then with both of us when she awoke.. Can't say enough about this entire process. Every staff member was smiling and joyful while discharging their duties. Thank You ALL for the high level of service and caring you provided..

Rick B.
7/8/25 I've had 10 colonoscopies in the last 25 years. This was my first visit with Dr Bologna. I read in some of his reviews about him returning a call late, not being compassionate enough, to some complaining about him wearing an Armani suit. Based on those complaints I still choose him based on his credentials.First,be glad your doctor has established his career enough to have earned the right to purchase what ever he wants. Would it make you fell better if your doctor wore shorts and a tank top?then there was a complaint about him being late on a phone call. Why should that be surprising? Ever been to a doctors vist when there on time? When I go too the doctors I educate myself in detail about my condition. When I ask questions and doctors see I actually know what I'm talking about they have always responded well. DR.Bologna and I spoke about my condition right before my procedure, we went over my past reports as well as photos, No small talk just strait business. His facility and staff were all very professional. They called in the afternoon to check on how I was doing. I would recommend him and his facility to any family members.
Thomas A L.

Tom S
I was weighed and the taken to an exam room promptly where BP and temp were taken. Dr. Wille came in shortly after and I was on my way home 20 minutes after my appointment time. Dr. Wille explained test results, discussed my situation, and ordered additional testing, and did not rush me at all.

Denise K.
I changed to Dr Willy because I wasn't getting any progress from my previous Dr. Things aren't going any differently here. He wants to schedule more tests that I've already had on more than one occasion. I had 17 ERCPs in 3 years with my previous DR. and now he wants another. I did the colonoscopy and EUS 2 years ago with Dr Willey. He said to make sure he didn't miss anything. If he missed something I don't want him as my Dr.!

Telehealth meeting with Jennifer was very convenient and was a consultation so no need to go to the office anyway. Jennifer was knowledgeable and answered all my questions thoughtfully and comprehensively. Good news is diagnosis was not too serious and she offered advice on diet and OTC medications to limit occurance of future episodes of acid reflux.

Noelle Maude is truly the only GI Healthcare provider that has listened to my symptoms and worked with me to improve them, rather than just giving me another pill to try.

Rachael was the most supportive, caring , and so thorough throughout this process. I had glitches with allergies and such but she worked through all the red tape with grace and poise. Procedure went smoothly and as scheduled. Rachael is such a gem and should definitely get extra kudos for her work on my complicated case. Bless you.

Dr. Jack Tocco is truly exceptional!
From the moment I walked into his office, I felt heard, respected, and genuinely cared for. He took the time to listen to my complex medical history, asked thoughtful questions, and explained everything in a way that was easy to understand. He never made me feel rushed or dismissed — instead, I felt like I had a true partner in my care.

His knowledge, professionalism, and kindness stood out immediately. I left the appointment feeling more confident and hopeful than I’ve felt in a long time. If you’re looking for a GI doctor who actually takes the time to understand YOU as a person and not just a list of symptoms, Dr. Tocco is the one. Highly, highly recommend!
Marcia L.
My appointment was for 3:30 . At 3:33 my name was called. Dr. Willie and his staff are the best.

annette E.
I recently had two procedures on June 26th, 2025. Upon arriving at the office, the staff was friendly and helpful. Check-in was seamless, and I barely waited before being called. The team efficiently gathered my information and assured me I’d be seen shortly. Within five minutes, I was in a room.

The nurse and CRNA gathered more information and then the CRNA promptly wheeled me to the procedure room. Both the assistant and doctor were already there, ready and kind. The CRNA and assistant quickly got me all set up, and before I knew it, I was awake and ready to go.

A kind staff member even escorted me to my car afterward. Overall, it was a 5-star experience!
Teresa H.
Staff was very nice, the Dr Bakken was very knowledgeable. And seem to have idea of how to care for my problems. Look forward to my next visit.

FAQs

What happens during my first visit?
If you are a new patient, you can expect to have a complete physical exam. You will also be asked detailed questions about your current problems and your past medical history, your current medications, allergies, your family history and other pertinent medical information. If you are taking medications, please bring a completed medical history form with you to your appointment. Once the physician has reviewed your medical information and completed the physical examination, a plan of care will be developed. You may need to be seen again in the office, be referred back to your family physician for follow-up care, or require additional testing. If additional tests are needed, we will assist you in scheduling these tests.
What if I need to schedule an endoscopic procedure?

An endoscopic procedure allows the physician to visualize a part of your gastrointestinal tract with a special instrument called an endoscope. If your family physician has ordered testing, you will be contacted by telephone by one of our staff members. If a physician orders testing and you are in the office, the procedure can generally be scheduled during the course of your visit. You will be given a date, time, and location for the test, as well as written instructions telling you how to prepare for the test. If you have any questions about the procedure, please feel free to ask one of our staff members or the physician.

How do I get test results?

We ask that you wait 10 to 14 days before contacting us for results. Often results come from several different sources. This information needs to be compiled and reviewed by your physician before you can be appropriately advised. 

What insurances do you accept?

We accept payment from most insurance companies including Medicare, Blue Cross/Blue Shield, Blue Care Network, Physicians Health Plan, Cofinity, Sparrow Professional Health Network, Medicaid, McLaren, Health Plus, and several others. Accepted insurances are subject to change at any time without notice.

If your insurance requires an authorization from your primary care physician, you may be asked to assist us in obtaining this authorization.

All patients are responsible for all copays and deductibles at the time of service.

If you have any questions regarding your benefits or insurance coverage, please contact our Billing Department at 248-844-9710.

What if I need to contact the doctor?

To contact your doctor during business hours please call our main number 248-844-9710. If you have an urgent need to speak with the doctor after hours, you will be rerouted to our after hours answering service, and your doctor will be paged. In the case of a medical emergency please proceed directly to the nearest hospital emergency room.
