What the published numbers say about pyloromyotomy, including the unflattering ones
Pyloromyotomy works well in selected patients and modestly at best in unselected ones. The gap between those two sentences is larger than most pages admit.
An international prospective trial ran the procedure across five tertiary centers in patients with refractory gastroparesis without tight selection. Of 80 enrolled, 75 completed 12 months. Clinical success was 56%, and the authors wrote plainly that unselective use of the procedure should be discouraged. In the same body of work, the predictors of success at one year were a baseline retention above 20% at four hours, a higher baseline symptom score, and an early response at one month.
Compare that to a randomized sham-controlled trial published in Gut in patients with severe, refractory disease. Treatment success at six months was 71% after pyloromyotomy against 22% after a sham procedure. Median retention at four hours dropped from 22% to 12% in the treated group and didn’t move after sham.
Cause matters too. In that trial, success ran highest in diabetic gastroparesis, lower in idiopathic disease, and lowest in post-surgical gastroparesis. Those subgroups were small and the confidence intervals were wide, so treat them as direction rather than a promise. Still, the direction is worth knowing before you drive across the bay: if your gastroparesis followed a prior operation, expectations get set differently from the start.
The AGA’s own position is that pyloromyotomy and gastric electrical stimulation should not be used routinely, even in patients who have failed medical therapy, and should be reserved for selected patients. The role of surgical pyloromyotomy and pyloroplasty was labeled an outright knowledge gap, with no recommendation issued either way. Nobody should present any of this as settled. The numbers above are from published series, not from this practice’s records.

What changed between October 2025 and now
Two things shifted, and both affect what happens at your next appointment.
The AGA published its first gastroparesis-specific practice guideline in October 2025: twelve recommendations, every one of them conditional. Four-hour emptying testing is in and 2-hour testing is out. Metoclopramide or erythromycin remains the starting point, with metoclopramide still the only drug FDA-approved for the condition. Domperidone, prucalopride, aprepitant, nortriptyline, buspirone and cannabidiol all drew recommendations against use as first-line therapy. Pyloromyotomy, gastric electrical stimulation and pyloric botulinum toxin were pushed out of routine use. The overall direction is tighter diagnosis and more conservative procedural use, which is a meaningful change from the 2022 ACG guidance many Tampa Bay physicians were still working from.
The drug pipeline moved as well. Naronapride, an oral prokinetic, completed a global Phase 2b trial in 328 adults with moderate to severe idiopathic or diabetic gastroparesis. The 20 mg and 40 mg three-times-daily doses beat placebo on the ANMS gastroparesis cardinal symptom diary score, with p values of 0.0046 and 0.0156, and improvement showed across nausea, early satiety, postprandial fullness and upper abdominal pain. Results were presented at Digestive Disease Week in May 2026, and on June 1, 2026 the sponsors announced they’re advancing into Phase 3 studies with a US new drug application planned off those results. The MOVE-IT trial record is closed to enrollment.
What that means for you, plainly: naronapride is not available, no approval date exists, and it is not a reason to postpone getting a correct diagnosis. If you want to be considered for a trial in the meantime, ClinicalTrials.gov is the registry to search, and enrollment status at any given site changes week to week, so verify by phone before you drive anywhere.
How an evaluation runs when you’re coming from Clearwater
Send your records before you come. That single step is what separates a first visit that produces a plan from a first visit that produces another appointment.
Email them to info@tampareflux.com ahead of the consultation. What matters most: the gastric emptying study report with the actual four-hour retention percentage, endoscopy and pathology reports, pH or manometry results if you’ve had them, any barium swallow or imaging, notes from your gastroenterologist and any ENT or pulmonary physicians involved, a full medication list including GLP-1 agonists and opioids, and a list of prior surgeries. Old studies still count. Progression over time is information. Our patient forms page has the paperwork to complete alongside them.
Signed releases alone are unreliable. Records get delayed, arrive incomplete, or land without the numeric data that actually drives the decision, and fax-based systems between Pinellas and Hillsborough practices are a real bottleneck. Patients who carry their own records get clearer answers faster.
The rest of the sequence:
- Testing you can complete near home gets done near home. The office coordinates with a small number of trusted testing sites to keep turnaround short and quality consistent, and no one is asked to cross the bay for a study that can be done in Pinellas.
- New patients are usually seen within two weeks, and within four weeks in every case.
- If your testing is already complete, one consultation is typically enough to reach a decision.
- If it isn’t, expect two visits roughly four weeks apart: the first for review and test planning, the second to go through results and decide.
- From first consultation to procedure runs about four to eight weeks depending on where your testing stands. Prior authorization paperwork is handled by the office and can add to that.
- Procedures are performed at HCA South Tampa Hospital with the same operating room team every case. A physician assistant employed by the practice assists in every operation and handles postoperative follow-up, so questions during recovery go to someone who was in the room. Dr. Grandhige is reachable directly after hours.
Nobody needs a referral to be seen, though most patients arrive with one from a Pinellas gastroenterologist, ENT physician or primary care physician.
Who treats you
Gopal Grandhige, MD, FACS is a board-certified general surgeon who has practiced foregut surgery in Tampa Bay since 2009. He trained at Johns Hopkins, the University of Michigan medical school, and Yale New Haven Hospital, where he completed general surgery residency plus fellowships in burn and critical care and in foregut and minimally invasive surgery. He is a Fellow of the American College of Surgeons, a member of SAGES, and a founding member of the American Foregut Society.
His practice is limited to benign disease of the esophagus, diaphragm and stomach. He does not treat esophageal or gastric cancer. Board certification can be verified through the American Board of Surgery physician lookup and licensure through the Florida Department of Health’s license verification tool, and you should check both for any surgeon you’re considering.
Volume in the reflux half of the practice is public: more than 600 fundoplications, more than 600 LINX implants and more than 200 TIF procedures. For gastroparesis specifically, he is one of a small number of surgeons performing per-oral pyloromyotomy in Tampa Bay. The office team includes medical assistants who have worked with him for over a decade and answer clinical questions directly rather than routing them. More detail on his background is on the about the practice page.

The practice holds a 4.9 star average across 37 Google reviews as of August 2026. Most of those reviewers came in for reflux rather than gastroparesis, so read them for how the practice operates, not as evidence about pyloric procedures.
