Why testing comes first, and what a normal endoscopy does not prove
A normal upper endoscopy does not rule out reflux. Endoscopy answers one question, which is whether reflux has caused visible damage. It does not measure reflux events, does not assess sphincter function, and does not record how often or when reflux happens. Small hiatal hernias are not visible on every endoscopy. Patients on acid suppression frequently have significant reflux and a completely clean scope.
Being told “your endoscopy was normal, so nothing is wrong” is the single most common reason Clearwater patients arrive here after years of medication.
Three tests do the real work. pH monitoring records reflux over 48 to 72 hours using either a wireless Bravo capsule or a catheter, capturing frequency, duration, acidity, timing, and whether symptoms line up with actual reflux events. Esophageal manometry measures contraction strength, swallow coordination, and sphincter relaxation, and it is what determines whether a full wrap is safe or a partial wrap is safer. Skipping manometry is how patients end up with lasting dysphagia. Barium swallow is used selectively, mostly for dysphagia, suspected strictures, or prior foregut surgery. It is worth knowing that patients correctly identify where food is sticking only about 60 percent of the time. Someone who feels an obstruction in the throat often has a delay in the lower esophagus instead.
Silent reflux requires different testing entirely. Standard reflux studies measure only above the lower esophageal sphincter, which misses the question that matters for throat symptoms. Dr. Grandhige uses a customized 24-hour pH impedance dual-channel probe that measures above both the lower and the upper esophageal sphincter, and detects non-acid reflux including bile, pepsin, and trypsin. The distinction is physiologic: the esophagus tolerates 40 to 50 reflux episodes a day, while the larynx and pharynx can produce symptoms from a single episode.
That testing changes the numbers. Patients with throat symptoms are commonly quoted a 50 percent chance that surgery helps. Selecting candidates with dual-channel testing raises expected symptom improvement to roughly 80 percent. Fewer patients get operated on, and the ones who do are far more likely to improve. The test is technically demanding and is not performed routinely in most practices.
How the operation gets chosen, and what is actually available
Procedure selection follows a six-step sequence, and it runs in order. Confirm that reflux is genuinely occurring. Map the anatomy, including hernia size, esophageal length, and the relationship between stomach, diaphragm, and esophagus. Measure esophageal function on manometry. Match individual symptoms to physiology, separating what should improve from what will not. Weigh patient priorities such as durability, the ability to belch, and reversibility. Only then choose a procedure, or choose none.
As Dr. Grandhige puts it, the operation is the last step. The decision-making is the surgery.
Motility drives the wrap. Good esophageal strength supports a Nissen, the full 360-degree wrap. Weaker motility points toward a partial wrap: Toupet at 270 degrees posteriorly, Watson at 270 degrees anteriorly, or Dor as an anterior partial. All four configurations are performed here, which is what allows the decision to follow the patient’s physiology rather than the surgeon’s habit.
Two alternatives exist for the right anatomy. LINX is a ring of magnetic titanium beads placed around the lower esophagus. It does not raise resting sphincter pressure; it resists opening when stomach pressure rises and opens for swallowing, which is why most patients keep the ability to belch and vomit once early swelling settles. It needs good motility. Hernia size does not disqualify anyone as long as the hernia is repaired at the same time. Current devices are MRI compatible to 1.5 Tesla, and the device can be removed. TIF is performed entirely through the mouth with the EsophyX device in 45 to 60 minutes. It cannot repair a hiatal hernia and does not address the diaphragm at all, so it is limited to patients with minimal or no hernia who are not obese.
Dr. Grandhige has performed over 600 fundoplications, over 600 LINX procedures, and over 200 TIF procedures.
One correction worth making, because several pages ranking for Clearwater reflux searches have it wrong: RefluxStop is not available in the United States. Implantica submitted its final response to the FDA on the RefluxStop premarket approval application on May 20, 2026, and a decision remains pending as of August 2026. Pages promising the device “in 2026” are describing something no American surgeon can currently offer. When approval comes, this practice intends to offer it. Until then it is not on the table.
Surgery day and recovery
Every foregut operation is performed at HCA South Tampa Hospital. That is deliberate rather than convenient. Dr. Grandhige previously operated at four area hospitals and consolidated to one so that the same anesthesia team, nurses, surgical technologists, and equipment are in place for every case, along with his own employed physician assistant who scrubs in on all of them.
The procedure is done laparoscopically or robotically under general anesthesia and typically takes 1.5 to 2 hours. Large hernias, scarring, or complex anatomy take longer. The stomach is reduced below the diaphragm, the hiatus is closed, the wrap is constructed in the configuration chosen before surgery, and the tension is checked before closing.
Most patients go home the same day, walking and taking liquids within hours. Arrange a driver for the ride back across the bay, since same-day discharge means you are leaving under anesthesia recovery, not staying overnight.
Diet advances over 2 to 3 months, from liquids to soft foods to regular textures. There is one recovery detail with real consequences: vomiting after surgery is associated with early failure of the hiatal hernia repair. Anesthesia is managed specifically to prevent postoperative nausea for that reason, and the same logic governs the early diet restrictions.
Dr. Grandhige’s physician assistant knows each patient’s anatomy and operation and is reachable during office hours. Dr. Grandhige is reachable directly after hours.
The risks and durability numbers most pages leave out
Anti-reflux surgery has real tradeoffs, and they should be named before a decision, not after.
The published data is worth reading alongside the practice’s own figures. A 2026 single-institution series of 1,226 hiatal hernia repairs, 99.6 percent of them laparoscopic, reported symptomatic recurrence requiring reoperation in 3.8 percent of cases at a median 12-month follow-up, with a 30-day reoperation rate of 2.6 percent and mortality of 0.1 percent. Two factors independently predicted early recurrence: open repair rather than laparoscopic, at an odds ratio of 5.37, and redo surgery in patients who had previous mesh, at an odds ratio of 7.69.
On mesh itself, the evidence is thinner than most consent conversations suggest. A 2025 network meta-analysis in Surgical Endoscopy comparing primary suture repair, absorbable mesh, and non-absorbable mesh found no significant differences between primary repair and mesh reinforcement across recurrence, dysphagia, complications, or reoperation, and its authors called for further randomized trials with long-term follow-up before drawing firm conclusions.
Reflux operations are functional procedures. Like a joint replacement, they work well, they are subject to wear, and some patients will need revision across a lifetime.
Two expectations need setting in advance. Surgery corrects reflux, not every symptom a patient brought in. Heartburn and regurgitation frequently resolve completely while bloating or abdominal pain driven by a different mechanism persist. And throat symptoms follow a slower curve: typical reflux symptoms often resolve almost immediately, while silent reflux symptoms usually take 4 to 6 months to improve.
For appropriately selected patients with typical symptoms, proven reflux, suitable anatomy, and good esophageal function, the practice reports symptom relief and elimination of daily reflux medication in over 95 percent of cases. These are the practice’s own reported outcomes rather than figures from an independent registry, and Dr. Grandhige is explicit that no procedure has a 100 percent success rate.
Who performs the surgery

Gopal Grandhige, MD, FACS is a board-certified general surgeon whose practice is limited to benign foregut disease, meaning conditions of the esophagus, diaphragm, and stomach. He completed a Bachelor of Science in Biology at Johns Hopkins University, his medical degree at the University of Michigan, and his general surgery residency at Yale-New Haven Hospital, followed by fellowships there 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 the Society of American Gastrointestinal and Endoscopic Surgeons, and a founding member of the American Foregut Society. He has practiced in Tampa Bay since 2009, founding Tampa Bay Reflux Center that year and Tampa Bay Reflux Institute in 2022.
He holds privileges at St. Joseph’s Main Hospital, St. Joseph’s South Hospital, HCA Brandon Hospital, and HCA South Tampa Hospital, and performs all foregut surgery at HCA South Tampa. Beyond reflux, he treats achalasia with Heller myotomy guided by EndoFLIP and gastroparesis with endoscopic pyloromyotomy. He does not treat esophageal or gastric cancer.
His office medical assistants have worked with him for over a decade, and his physician assistant is directly employed by the practice rather than assigned by the hospital.
Credentials can be verified independently through the American Board of Surgery physician lookup, the American College of Surgeons directory, and the Florida Department of Health Medical Quality Assurance license search. The practice holds a 4.9 star rating across 37 Google reviews as of August 2026, where the recurring theme in patient feedback is the hand-drawn diagrams Dr. Grandhige uses to explain each patient’s own anatomy.
Common questions from Clearwater patients
Start with an evaluation, not an operation
If you have been on acid suppression for years without anyone reassessing whether it is working, or you were told a normal endoscopy meant nothing was wrong, the next step is objective testing rather than another prescription. Email your prior records to info@tampareflux.com, and the first visit can be spent on your results instead of your paperwork.
An endoscopy cannot tell you if you have reflux. It can only tell you if you have complications of GERD.
If you are unhappy with your reflux symptoms, come in and we can discuss testing and treatments that can accurately diagnose your problem.
