Louisville, Kentucky — Gastroparesis Surgery

More gastroparesis surgeries than any surgeon in the world.

Dr. Michael Hughes has placed more than 2,500 gastric stimulators and performed more than 2,000 pyloroplasties. Vanguard treats gastroparesis and nothing else — medically as well as surgically — so the recommendation you get is the one that actually fits you.

Understand your disease before you decide anything.

A free one-hour seminar, online, open to anyone anywhere. Not a consultation, not telehealth, not a sales pitch. You do not need to live in Kentucky or Indiana, and attending commits you to nothing.

What gets covered

  • How a normal stomach works, and what the pylorus does
  • Why your stomach is under pressure — and why that, not slow emptying, causes most of what you feel
  • Diet, medication, and both operations
  • Recovery, risks, and honest numbers

The one thing worth understanding

Two patients. The same nausea. Different operations.

The nausea comes from the vagus nerve — think of it as a smoke alarm wired to your stomach. What tells the two situations apart isn't a test. It's the company the nausea keeps.

How Vanguard Surgical chooses between pyloroplasty and gastric stimulation The vagus nerve acts like a smoke alarm. If nausea comes with bloating, fullness and pain, the stomach is under pressure and pyloroplasty removes the trigger: two in three patients improve, one in three are left with a stuck alarm and go on to gastric stimulation. If nausea comes alone with no pressure, the alarm is already stuck and the patient skips pyloroplasty and goes straight to gastric stimulation. Two patients. The same nausea. Different operations. The vagus nerve is a smoke alarm wired to your stomach. Does the nausea come with bloating, fullness and pain? YES NO Stomach under pressure Food and air build up behind a pylorus that won't open. The stretch trips the alarm. No pressure at all Nausea and vomiting alone. Nothing to decompress — the alarm is already stuck on. PYLOROPLASTY Removes the trigger for the alarm 2 in 3 The alarm quiets. No device needed. 1 in 3 Pressure is gone but the alarm stays on. Skips pyloroplasty entirely GASTRIC STIMULATION Turns the alarm down directly What tells the two apart isn't a test. It's the company the nausea keeps. Vanguard Surgical · vanguardsurgical.net

Treatment Options

Medical and surgical management.

Most practices that treat gastroparesis do one or the other. A practice that only operates will steer you toward the operating room.

Here, medication is a real option rather than a formality on the way to surgery. Most patients are managed medically first. Surgery is what happens when medication has genuinely been given its chance.

For referring physicians: one referral covers the whole pathway. Diet, medication and both operations are handled here, so the patient doesn't come back to you needing to be sent somewhere else.

The treatment sequence

How this practice is different

Gastroparesis is the whole practice

Most surgeons who treat gastroparesis treat many other things, and these patients end up as the difficult cases wedged between more straightforward work. Here they are the entire practice.

Private practice, not university

No trainees managing your care. You are seen by the surgeon who will operate on you, and by the nurse practitioner who will manage your medication.

Outpatient surgery center

Both operations are done at an ambulatory surgical center — lower cost than a hospital, lower infection rates, and home the same day.

He teaches other surgeons

Dr. Hughes trains and advises other surgeons on stimulator placement and management on behalf of Enterra Medical, the device's manufacturer.

For healthcare providers

Refer a patient

Digital referral, or a downloadable form. Dr. Hughes handles peer-to-peer reviews himself when a procedure is denied, and appeals on the patient's behalf where necessary.

Who to send

  • Nausea and vomiting despite diet and medication
  • Bloating, fullness and upper abdominal pain
  • Failed G-POEM or prior pyloric intervention
  • Patients you'd rather not manage long-term yourself

Start with the seminar. Decide afterwards.

One hour, online, free, and it commits you to nothing. You do not need to live in Kentucky or Indiana.
