The four tests, and the question each one answers
Upper endoscopy cannot diagnose GERD. A normal endoscopy does not mean you do not have reflux, and being told “everything looked fine” is the most common reason people spend another five years on medication.
Each test answers a different question, and skipping one is how the wrong procedure gets chosen.
Upper endoscopy (EGD) answers whether reflux has caused damage. It finds esophagitis, Barrett’s esophagus, strictures, and ulcers, and it allows biopsies. It does not measure reflux events, sphincter function, or timing. Small hiatal hernias are missed on plenty of endoscopies.
pH monitoring answers whether reflux is occurring, how much, and whether it lines up with what you feel. A wireless Bravo capsule or a catheter records 48 to 72 hours while you eat, sleep, exercise, and work normally, capturing frequency, duration, acidity, timing, and symptom correlation. This is the test that separates reflux from esophageal hypersensitivity, functional chest pain, and motility disorders, all of which feel similar and none of which respond to reflux surgery.
Esophageal manometry answers whether your esophagus is strong and coordinated enough to handle a reflux procedure at all. It measures contraction strength, swallow coordination, and sphincter relaxation, and it identifies achalasia, esophageal spasm, ineffective motility, and jackhammer esophagus. It is what decides between a full wrap and a partial one. Skipping it is how patients end up with swallowing problems they did not need to have.
Barium swallow (esophagram) answers what happens when you actually swallow. It is used selectively: dysphagia, suspected narrowing, prior foregut surgery, or findings that contradict your symptoms. One detail from this study rarely makes it onto other pages. Where you feel food getting stuck is the true anatomic location only about 60 percent of the time. Patients point at their throat while the delay is sitting in the lower esophagus.

Silent reflux is tested differently here, and it changes who should have surgery
Standard reflux testing measures reflux above the lower esophageal sphincter. If your symptoms are in your throat, the reflux that matters is traveling above the upper esophageal sphincter, and standard testing does not look there.
The difference in tissue sensitivity explains why this gets missed. The esophagus can tolerate 40 to 50 reflux episodes a day without complaint. The larynx and pharynx can produce symptoms from a single episode a day.
Dr. Grandhige uses a customized 24-hour pH impedance dual-channel probe placed in the office. It measures reflux at both levels, above the lower sphincter and above the upper one, and it detects non-acid reflux. That matters because bile, pepsin, and trypsin irritate throat tissue and cannot be picked up by a pH sensor alone. Only impedance sees them.
Here is what that testing does to the odds. Patients with silent reflux (LPR) are commonly quoted around a 50 percent chance that surgery helps, a number that comes from operating on a group selected by symptoms. With dual-level testing guiding selection, symptom improvement runs closer to 80 percent. The trade-off is that only about 50 to 60 percent of LPR patients turn out to have testing that supports surgery. The rest are told no, which is the point.
One more honest note on timing. LPR symptoms take 4 to 6 months to improve. Typical heartburn and regurgitation often resolve almost immediately. Anyone promising a fast fix for chronic throat clearing, hoarseness, cough, postnasal drip, ear fullness, or a lump-in-the-throat sensation is not describing how this condition actually behaves.
The procedures, and who each one actually fits
There is no best reflux operation. There is the right operation for your anatomy and your esophageal function, and in a meaningful share of cases the right answer is no operation. As Dr. Grandhige puts it, the operation is the last step. The decision-making is the surgery.
Results, side effects, and the patients he turns away
In patients with objective evidence of reflux, workable anatomy, and good esophageal function treated with standard anti-reflux procedures, Dr. Grandhige reports greater than 95 percent success in meaningful symptom relief and elimination of daily reflux medication.
Every qualifier in that sentence is doing work. Outcomes come down in patients with reduced esophageal motility, long-standing disease, large or recurrent hernias, prior foregut surgery, or previous bariatric surgery. Those cases get individual expectation-setting before anything is scheduled, not after.
Side effects are covered before you decide, not in a consent form on the morning of surgery: swallowing changes during healing, gas and bloating, changes to burping and vomiting, durability, and revision risk over a lifetime. One detail shapes the entire recovery plan. Vomiting after surgery is associated with early failure of a hiatal hernia repair, which is why nausea control is handled as part of the operation rather than an afterthought.
He also turns people away, and he is direct about it. Patients whose testing shows no objective reflux, along with those with esophageal hypersensitivity, functional chest pain, rumination, and severe motility disorders, are not candidates. Achalasia gets a Heller myotomy tailored with Endoflip instead, because it is a different disease that mimics reflux. These are frequently the least satisfied patients in the practice. They would be far less satisfied after an operation that fixed nothing.
Success here means your reflux symptoms improve. Symptoms that were never reflux do not. He asks patients to give it six months, then addresses whatever remains, sometimes by sending you to a specialist he already works with.
The practice holds a 4.9 star average across 37 Google reviews. What repeats in them is not the surgery. It is the hand-drawn diagrams, the explanation, and not being pushed toward an operation. Gastroenterologists, ENT physicians, pulmonologists, allergists, and primary care doctors across Tampa Bay refer here for the same reason.
What treatment looks like when you live in Clearwater
Most Clearwater patients make two trips across the bay, and the office arranges for whatever testing can be done near home to be done near home.
The office sits at 1315 S Howard Ave, Suite 101 in South Tampa. From Clearwater the direct route is the Courtney Campbell Causeway (SR 60), usually 25 to 40 minutes outside of rush hour. I-275 across the Howard Frankland is the alternative, and FDOT expects that rebuild to wrap up in summer 2026 with express lanes running in both directions.

Send records before you come. Email prior endoscopy and pathology reports, pH studies (Bravo or catheter), manometry results, barium swallow or other imaging, office notes from your gastroenterologist, ENT, pulmonologist, or allergist, a current and past medication list, and a list of prior surgeries to info@tampareflux.com. Studies from years ago are still useful for showing progression. Dr. Grandhige reviews all of it before you sit down, which turns the first visit into a decision instead of an intake. A signed records release alone tends not to work. Fax-based systems and incompatible electronic records mean reports arrive late, incomplete, or not at all.
Wait time to be seen is usually within 2 weeks and always within 4.
From there the path splits. If your testing is already complete, one consultation is typically enough, and surgery can be scheduled as early as about 4 weeks from that visit. If testing is not complete, the first visit covers education and test planning, a second visit follows roughly 4 weeks later to review results and finalize the plan, and surgery lands around 8 weeks from the first appointment. Insurance authorization runs in parallel and can take 4 to 6 weeks on its own, which is usually the piece that sets the date.
Surgery happens at HCA South Tampa Hospital, every case, with the same operating room team, the same anesthesiologists, and the same physician assistant who scrubs in on every one of Dr. Grandhige’s operations. He previously operated at four area hospitals and consolidated to one deliberately, because familiarity with foregut equipment and anticipating problems beats convenience. After hours, patients reach him directly.
