Severe Gastroparesis Treatment In Clearwater, FL

If diet changes, prokinetics, and anti-nausea medication have stopped working, the next step is not another prescription. It is objective testing to confirm what is actually causing the delay, and whether a procedure can reach it.

Tampa Bay Reflux Institute is a foregut surgery practice about 25 miles from Clearwater across the Courtney Campbell Causeway. Dr. Gopal Grandhige has treated conditions of the esophagus, stomach, and diaphragm in Tampa Bay since 2009. He performs endoscopic pyloromyotomy for selected patients whose symptoms remain refractory after medical therapy, and he tells a meaningful number of patients that a procedure will not help them.

What counts as severe gastroparesis, and when a Clearwater patient should see a foregut surgeon

Severe gastroparesis means symptoms that persist after medical therapy has been given a real trial. That is the threshold that matters, because it is the line that separates patients who should stay on medical management from the smaller group for whom a procedure becomes reasonable.

The basics of the condition, its causes, the standard workup, and the full range of treatments are covered on our main gastroparesis page. This page is for the stage after that: you already have the diagnosis, or you have the symptoms and nobody has explained them.

Consider a foregut evaluation if any of these apply:

  • You vomit undigested food hours after eating despite prokinetic therapy.
  • You are losing weight without trying, or you cannot maintain nutrition.
  • You have had emergency room visits or admissions for dehydration or intractable nausea.
  • A gastric emptying study confirmed delay and your symptoms have not improved on medication.
  • You have been told your emptying study was normal, but your symptoms are unchanged and unexplained.

There is one more reason, and it is the one most often missed. Gastroparesis symptoms overlap heavily with other foregut conditions. Nausea, regurgitation, bloating, and early fullness show up in GERD, in hiatal hernias, and in esophageal motility disorders. Patients frequently carry more than one of these at the same time. Treating the wrong one leaves the patient exactly where they started, which is why Dr. Grandhige sorts out which condition is driving which symptom before recommending anything.

What changed in 2025 and 2026, and why it matters before you agree to a procedure

The American Gastroenterological Association published its first clinical practice guideline on gastroparesis in September 2025, and it moved endoscopic pyloromyotomy out of the early-treatment slot. If you were counseled about this condition before then, your information predates the guideline.

The AGA guideline issued 12 conditional recommendations. The ones that change patient decisions:

  • Against 2-hour or shorter gastric emptying protocols, and in favor of the full 4-hour study, because shorter tests produce both false negatives and false positives at high rates.
  • In favor of metoclopramide and erythromycin as pharmacologic options, with the metoclopramide black box warning discussed before starting.
  • Against domperidone, prucalopride, aprepitant, nortriptyline, buspirone, and cannabidiol as first-line therapy.
  • Against the routine initial use of gastric per-oral endoscopic pyloromyotomy or gastric electrical stimulation, reserving both for select patients whose symptoms are refractory to medical therapy.
  • Against the routine use of pyloric botulinum toxin injection.
  • No recommendation either way on surgical pyloromyotomy and pyloroplasty, which the panel flagged as knowledge gaps.
gastroparesis

The practical takeaway for a Clearwater patient: if your emptying study was a 2-hour protocol and came back normal, that result is not conclusive under current guidance. Bring the report to your visit. The protocol length is on it.

On the medication side, one drug is moving toward approval. Dr. Falk Pharma and Renexxion announced results from MOVE-IT in May 2026, a global Phase 2b trial of naronapride in 328 adults with moderate-to-severe idiopathic or diabetic gastroparesis and confirmed delayed emptying. The trial met its primary endpoint on the ANMS gastroparesis symptom score, and the companies announced in June 2026 that they are advancing to Phase 3 with a planned United States filing. Naronapride is not available. Metoclopramide remains the only drug FDA-approved for gastroparesis.

That matters for timing. If you are close to the line on whether to have a procedure, knowing a new agent is in late-stage development is part of the decision, not a footnote.

Four checks before Dr. Grandhige will consider a pyloromyotomy

No procedure is offered on symptoms alone. Four things get confirmed first.

1. The delay is objectively documented. A full 4-hour gastric emptying study, not a shortened protocol. A symptom pattern that looks like gastroparesis is not a diagnosis.

2. Mechanical obstruction is ruled out. Upper endoscopy, which also shows whether food is retained after an adequate fast.

3. Overlapping foregut disease is sorted out. Where indicated, this includes pH monitoring, esophageal manometry, or a barium swallow. Manometry matters more than most patients expect, because achalasia and other motility disorders can present with regurgitation and chest discomfort that read as gastroparesis or reflux.

4. Medical therapy has been given a real trial. Dietary modification, glycemic control where diabetes is involved, and a documented trial of prokinetic therapy. This is also what the AGA guideline expects before a procedure is on the table.

Dr. Grandhige personally reviews every prior study before your appointment. That includes endoscopy and pathology reports, pH testing, manometry, imaging, prior operative reports, and the office notes from your gastroenterologist, ENT, pulmonologist, allergist, or primary care physician. He reviews what other physicians concluded, not just the raw results, so his opinion is explained in the context of the opinions you have already been given.

Sending records to info@tampareflux.com before your visit is the single biggest factor in whether one appointment is enough or whether you need two. Signed release forms are submitted immediately, but records requested through fax and incompatible record systems arrive slowly and often incomplete. Our patient forms page has what to bring.

Endoscopic pyloromyotomy: what the published data shows, and what it does not fix

Endoscopic pyloromyotomy improves symptoms in roughly seven out of ten carefully selected refractory patients at one year, and the benefit fades for some of them over the following two years.

Those numbers come from a 2024 systematic review and meta-analysis of 13 studies covering 952 patients with refractory gastroparesis. The pooled results showed 72% clinical success at one year. Among patients who were successful at one year, 71% remained so at two years and 58% at three years. The pooled adverse event rate was 8%.

The procedure is performed through the mouth with a flexible endoscope. A tunnel is created under the pyloric muscle, the muscle is divided, and the outlet of the stomach opens. There are no abdominal incisions and most patients go home the same day. The mechanics are described in more detail on our main gastroparesis page.

What it does not do:

  • It does not cure gastroparesis. Nothing currently available does. It targets outflow resistance at the pylorus and reduces symptom burden.
  • It does not help every symptom equally. Nausea and fullness respond more reliably than abdominal pain.
  • It does not help when the delay is driven by the body of the stomach rather than the valve at its outlet.
  • It is not permanent for everyone. The three-year data above is the honest version of durability.

Dr. Grandhige’s position is consistent across his practice: the patients he declines to operate on are frequently the most frustrated, and they are also the patients who would have been more frustrated after a procedure that could not reach their mechanism. Declining is part of the job.

What this practice does not do for gastroparesis

Dr. Grandhige does not implant gastric electrical stimulators. If that is the right path for you, he will say so and refer you.

The AGA guideline suggests against the routine use of gastric electrical stimulation, reserving it for select patients with medically refractory disease, and notes that it aims primarily at nausea and vomiting rather than abdominal pain. That framing is worth carrying into any conversation about the device.

Two other paths exist for the most severe end of the spectrum, and both are described on our main gastroparesis page. For patients with severe weight loss and malnutrition who are not candidates for a definitive procedure, venting and feeding access can stabilize nutrition first so that other options become safe to consider. Subtotal gastrectomy is reserved for the small number of patients whose disease is severe enough to be life-limiting after everything else has been exhausted.

This practice treats benign disease of the esophagus, stomach, and diaphragm. Cancer of the esophagus or stomach is outside its scope. When symptoms turn out not to be foregut-driven, Dr. Grandhige refers back to gastroenterology, ENT, pulmonology, or allergy, and he has working relationships with those physicians so the handoff does not restart your workup from zero.

How the process works when you are driving in from Clearwater

Most patients are seen within two weeks and always within four, and reach a treatment decision in one or two visits.

Here is the actual sequence:

  • If your testing is already complete, one consultation is usually enough. The diagnosis can be confirmed at that visit and options discussed the same day.
  • If testing is still needed, the first visit covers records review, education, and test planning. A second visit about four weeks later reviews results and finalizes the plan.
  • From first consultation to procedure is typically four to eight weeks, depending on where your testing stands.
  • Insurance authorization can take four to six weeks and is handled entirely by the office. It is secured before anything is scheduled, so nothing proceeds under uncertainty. Patients who call their own insurance company usually slow this down rather than speed it up.

For patients coming from Pinellas County, testing that can be done near you is done near you. The office works with a small number of testing sites to keep scheduling and result turnaround predictable, and it coordinates studies onto the fewest possible days so you are not making repeated trips across the bay. Out-of-town patients get help with travel timing and logistics as a matter of routine.

The office is at 1315 South Howard Avenue, Suite 101, Tampa, Florida 33606. It is a yellow brick building next door to Sally O’Neill’s Pizza, and parking is behind the restaurant. From downtown Clearwater the drive is roughly 30 to 45 minutes across the Courtney Campbell Causeway depending on traffic. All surgical procedures are performed at HCA South Tampa Hospital, where Dr. Grandhige operates with the same team on every case.

Phone: 813.922.2920. Office hours are 9 AM to 6 PM, Monday through Friday. Records go to info@tampareflux.com.

Dr. Gopal Grandhige, MD, and the team you will actually see

Dr Grandhige both hands on pockets

Dr. Grandhige is a board-certified general surgeon with fellowship training in foregut and minimally invasive surgery. He has practiced foregut surgery in Tampa Bay since 2009.

His training: Bachelor of Science in Biology from Johns Hopkins University, medical degree from the University of Michigan, general surgery residency at Yale-New Haven Hospital, a fellowship in burn and critical care at Yale-New Haven, and a fellowship in foregut surgery and minimally invasive surgery at Yale-New Haven. He founded and directed Tampa Bay Reflux Center from 2009 to 2022 and founded Tampa Bay Reflux Institute in 2022. He is a Fellow of the American College of Surgeons, a member of the Society of American Gastrointestinal and Endoscopic Surgeons, and a founding member of the American Foregut Society.

Board certification can be verified through the American Board of Surgery physician lookup and the American College of Surgeons directory. Active Florida licensure and any disciplinary history can be verified through the Florida Department of Health Medical Quality Assurance license lookup. More background is on the about us page.

Continuity is structural here rather than aspirational. The same physician assistant, employed by the practice, assists in every surgical case, participates in operative planning, and is involved in postoperative care. Several medical assistants have worked with Dr. Grandhige for more than a decade. After hours, patients reach Dr. Grandhige directly rather than a call service.

Because foregut conditions cluster, patients evaluated for gastroparesis are often evaluated for related problems at the same visit. Dr. Grandhige also treats silent reflux and LPR, hiatal hernias, achalasia, and GERD, and he performs fundoplication, LINX, and TIF for reflux patients when those are indicated.

Frequently asked questions

Not on its own. Check the protocol length on the report. The AGA recommends against 2-hour and shorter studies because they produce false negatives and false positives at high rates, and recommends the full 4-hour study instead. A normal 2-hour result in a patient with ongoing symptoms is a reason to repeat the test properly, not a reason to stop looking.

Not to be seen. Most patients arrive by physician referral, but you can contact the office directly. Bring your records either way, because the value of the first visit depends on what is available to review before it.

When the study can be done well near you, yes. The office routinely arranges local testing for out-of-area patients and consolidates whatever must be done in Tampa onto the fewest possible days.

Four to six weeks is typical, and the office handles the submission and follow-up. Authorization is secured before a procedure is scheduled, so you will know where you stand before any date is set.

There are no abdominal incisions, and most patients go home the same day. Your specific diet progression and activity restrictions are set at your preoperative visit, since they depend on your anatomy and nutritional status.

It happens. In the pooled long-term data, a portion of patients who responded at one year had lost that response by three years. That possibility is discussed before the procedure, not after, and remaining options are reassessed if it occurs.

That is precisely what the testing sequence is designed to answer. Delayed emptying can drive reflux symptoms, and reflux and hiatal hernia can produce fullness and nausea that mimic gastroparesis. The order depends on which mechanism the objective testing identifies as the primary driver.

You will be told why, in plain terms, along with what he thinks is actually causing your symptoms and who should manage it. A consultation that ends without a procedure is a normal outcome here, not a failed visit.

Take the next step

You have a diagnosis or a set of symptoms that has not been explained, and you have already tried the standard ladder. The next useful thing is objective testing interpreted by a surgeon who does this every day and who will tell you when an operation is the wrong answer.
