miVU Technology Now Used for Patients with GERD

June 26, 2026

Schoolcraft Memorial Hospital Among First in Michigan to Offer Advanced Reflux Testing During Endoscopy

New technology provides real-time answers for patients suffering from chronic acid reflux.

Schoolcraft Memorial Hospital is proud to announce the addition of the MiVu™ Mucosal Integrity Testing System, making SMH just the second hospital in the State of Michigan to offer this innovative technology during upper endoscopy.

The advanced diagnostic tool helps physicians determine whether acid reflux is causing damage to the esophagus—providing immediate results during a procedure many patients are already scheduled to receive.


A Better Way to Diagnose Acid Reflux

Millions of people experience symptoms such as:

  • Chronic heartburn
  • Regurgitation
  • Chest discomfort
  • Chronic cough
  • Difficulty swallowing

For many patients, these symptoms continue despite medications or lifestyle changes. Finding the true cause can often require multiple tests and lengthy evaluations.

The MiVu™ system changes that.

During a standard upper endoscopy, a specialized probe measures the health of the esophageal lining by detecting subtle electrical changes caused by long-term acid exposure. The results are available immediately, helping physicians make more informed treatment decisions without requiring another appointment or additional testing.


Faster Answers, Better Treatment

According to Dr. Medhat Fanous, General Surgeon and acid reflux specialist at Schoolcraft Memorial Hospital, the technology offers significant benefits for patients.

“Many patients come to us after years of symptoms and multiple rounds of treatment that haven’t worked,” said Dr. Fanous.

“Mucosal integrity testing lets us see, in real time, whether the esophageal lining has been damaged by acid. That means fewer inconclusive results, fewer follow-up tests, and a faster path to the right treatment. For our patients in the Upper Peninsula, having this available locally—during a procedure they’re already having—is a meaningful step forward.”


Benefits of Mucosal Integrity Testing

Patients may benefit from:

  • Immediate diagnostic information during endoscopy
  • More accurate diagnosis of GERD
  • Better distinction between acid reflux and other gastrointestinal conditions
  • Fewer follow-up procedures
  • Access to advanced reflux care close to home


Who Should Consider This Test?

Your provider may recommend mucosal integrity testing if you experience:

  • Persistent heartburn or acid reflux
  • Symptoms that do not improve with acid-reducing medications
  • Difficulty or pain with swallowing
  • Chronic cough or frequent throat clearing
  • Evaluation before anti-reflux surgery or advanced reflux treatment

Bringing Advanced Care to Rural Michigan

“Investing in technology like this reflects who we are as an organization,” said Robert Mach, Chief Executive Officer of Schoolcraft Memorial Hospital.

“As an independent critical access hospital, our mission is to bring advanced, high-quality healthcare services to patients across our region. We are proud to continue expanding access to specialized care so patients can receive leading-edge treatment close to home, from a team they know and trust.”
