Skip to main contentAhmedabad and Gandhinagar · Dr Harsh Shah, Laparoscopic & Endoscopic Stomach Surgeon
Gastroparesis is a stomach that empties late without anything blocking it, and almost nobody with it needs an operation first. The order that works is the opposite of what most patients arrive expecting: prove the delay, remove the causes that can be reversed, fix the diet, use the medicines properly — and only then consider a procedure, matched to the one problem that is actually dominant. A pylorus that will not relax is treated differently from a patient who cannot keep food down, and both are treated differently from a stomach that has failed after previous surgery. The operation is chosen from the phenotype, never from the label.

Laparoscopic & Endoscopic Stomach Surgeon
· Apollo Hospital, Bhat, Gandhinagar · Gota OPD, Ahmedabad
Qualified twice over in surgical gastroenterology. Gastroparesis is the condition where a surgeon is most often asked to operate and most often right to decline — which is why Dr Harsh Shah assesses it as a motility problem first and a surgical problem second. Patients referred with “refractory” disease frequently turn out to be on a drug that stops the stomach, or to have never completed a proper four-hour emptying study. Google rating 4.89 from 216 reviews at the Gota listing, and 4.94 from 17 reviews at the Apollo, Bhat listing.
The label of gastroparesis is only allowed once three things are true together: the symptoms fit, the emptying is objectively delayed, and nothing is mechanically blocking the way out. Miss any one of the three and the wrong disease gets treated — usually for years.
Nausea that never quite lifts, vomiting, feeling full after a few mouthfuls, fullness and bloating after meals, upper abdominal discomfort — that cluster is the reason most people are sent. It is not, on its own, a diagnosis. Two other groups matter: a person with diabetes whose sugars swing unpredictably after meals, and anyone who developed these symptoms after foregut, weight-loss or cancer surgery. In that second group the anatomy is guilty until proven innocent.
| Step | What it settles |
|---|---|
| Upper GI endoscopy | Rules out the things that actually block the exit — a narrowing, a tight previous join, an ulcer, a growth, a ball of undigested fibre. Retained food after a proper fast is itself a finding. |
| Contrast study or cross-sectional imaging | Used where the scope is equivocal, and in every patient who has had previous surgery, to confirm the outlet is open and there is no internal hernia. |
| A four-hour solid-meal gastric-emptying study | The test that proves the delay. Images are taken through to the four-hour mark. A study stopped at two hours misses a large share of real cases and should be treated as incomplete, not as normal. |
| Medicine review and glucose control before testing | Opioids, anticholinergics and the GLP-1 weight and diabetes injections all slow the stomach. High blood sugar slows it further. Testing before these are corrected produces a delayed result that means nothing. |
Blood tests at the first visit cover sugar control, kidney function, magnesium, thyroid, B12, iron, vitamin D and albumin, with a heart tracing where a medicine affecting heart rhythm is being considered. Recent weight loss, a low body mass index, a low albumin, or intake well below need, each trigger a dietitian review at that first visit rather than later.
A large share of patients labelled refractory are simply under-corrected. Blood sugar, and the medicines that paralyse the stomach, come off the table before any chronic treatment is layered on top — never after.
| Reversible driver | What is done about it |
|---|---|
| Opioid painkillers | Stopped or substituted. Opioids are actively counter-therapeutic here; they are also the commonest reason a patient stops responding to treatment that was working. |
| GLP-1 receptor agonists for diabetes or weight | Reviewed with the treating physician and usually stopped before testing. They slow gastric emptying by design. |
| Anticholinergic medicines | Identified across the whole prescription list, including ones taken for bladder, sleep or allergy, and substituted. |
| Poor glycaemic control | Brought down before any emptying test, because a high sugar reading on the day falsely delays the study. |
| Low potassium, low magnesium, dehydration | Corrected. These prolong the problem and make every other treatment look like it has failed. |
Diet in gastroparesis is treatment, not advice. Small frequent meals, low fat, low coarse fibre and small particle size have been tested against ordinary dietary advice and work; sitting upright for a hour or two after eating adds to that.
As the disease gets more severe the diet shifts towards softer and more liquid calories, because a liquid leaves the stomach even when solid food will not. Four to six small meals replace three large ones, and coarse insoluble fibre is restricted — it is also what forms a bezoar, the ball of undigested material that can block the outlet and mimic a relapse.
Medicines are then used in parallel rather than in sequence: a prokinetic to move the stomach and an anti-sickness drug to make eating possible. Each has a real limit explained before it is started — one is capped at a defined number of weeks because of a movement-disorder risk, one needs a heart tracing before and during treatment, and one loses its effect after a few weeks and is kept for short courses. Where the dominant complaint is nausea and early fullness rather than measured delay, medicines acting on how the stomach relaxes to receive food often do more than another prokinetic. Older antidepressants were tested here and did not improve emptying, so they are not used expecting that they will.
Only when all of that has genuinely been done — the reversible causes cleared, the diet implemented properly, two different classes of prokinetic tried at adequate dose, anti-sickness medicines used alongside, and conditions that imitate gastroparesis excluded — is a patient refractory. That documented trial is also what an insurer or a public scheme looks for before approving any procedure.
There is no single gastroparesis operation. Four different problems hide under the one word, and each has its own procedure. Choosing one favourite operation and offering it to everybody is the commonest way surgery fails in this disease.
| Dominant problem | Procedure | What it does and does not do |
|---|---|---|
| The pylorus, the muscular outlet of the stomach, will not relax | G-POEM — the outlet muscle is divided from inside, through the endoscope, with no cut on the abdomen — or a laparoscopic pyloroplasty, which widens the same outlet through keyhole surgery | The best-supported option, and the only one tested against a dummy procedure. Most carefully selected patients improve; a real minority do not, and the benefit can fade over the first year. An incompletely divided muscle is the commonest fixable reason for no response. |
| Relentless nausea and vomiting in long-standing diabetes | Gastric electrical stimulation, after a temporary trial shows it helps | A symptom device, not a prokinetic — it reduces vomiting without making the stomach empty faster. A lifelong implant with infection and revision risk, and rarely funded in India. |
| Losing weight, cannot maintain nutrition, vomiting through everything | Feeding jejunostomy, a small tube into the small bowel, sometimes with a venting tube in the stomach | Frequently the most life-changing operation on this list and the least dramatic. Feeding into the bowel is preferred to feeding into a vein. |
| End-stage disease after previous stomach surgery, everything else exhausted | Subtotal or total gastrectomy with a Roux-en-Y reconstruction | A genuine last resort with its own stasis risk, considered only in the post-surgical group and only after everything above has failed. |
Where two of these are needed they are combined in one anaesthetic — widening the outlet and placing feeding access at the same sitting, for instance. The sequence across the whole list is set by how reversible each step is: drainage and feeding access first, a stimulator only after a positive temporary trial, removal of the stomach last.
Botulinum toxin injected into the pylorus is still offered widely in India. Two randomised trials tested it and neither showed it worked. It is, at most, an imperfect way of predicting who might respond to a proper procedure — it is not therapy, and this practice does not present it as therapy.
It matters because a patient who is told the injection is the treatment, and then finds the relief lasting only weeks, often concludes that nothing surgical will help — and stops short of the procedure that might actually have worked. Where the question is genuinely whether the outlet is tight, the answer comes from measuring how the pylorus opens during endoscopy, not from an injection.
Both outlet procedures are short and recovery is quick. After an endoscopic myotomy most people go home on the first or second day; after a keyhole pyloroplasty, within a few days.
Preparation is specific to this disease. Everything reversible is re-cleared first, and nutrition is optimised before rather than after, with a trial of tube feeding in anyone significantly malnourished. Carbohydrate drinks before surgery, routine in most operations, are deliberately omitted: in a stomach that empties late they are unsafe. A clear-liquid diet the day before, and treating the stomach as full at induction whatever the fasting time, follow from the same fact.
During an endoscopic myotomy the full thickness of the outlet muscle is divided and the entry point closed securely; during a pyloroplasty the channel is inspected with the endoscope on the table to confirm it is open and the lining is intact. Afterwards: out of bed the same day, pain controlled without opioids because opioids work against the disease, clear liquids on the first day with a soft small-particle diet the next, and where a feeding tube was placed, feeds started slowly and the family trained to look after it before discharge. You go home once you are afebrile for a day, eating soft food or established on feeds, walking independently, comfortable on tablets, and holding a written plan with explicit stop dates for each medicine and a red-flag sheet.
An operation is the wrong step when the delay has never been objectively proved, when a reversible cause is still in place, when the symptoms are nausea and pain rather than measured retention, and in the early months after major foregut or cancer surgery, when stasis is usually part of recovery.
Two other situations are regularly mistaken for gastroparesis and are made worse by operating: rumination and cyclical vomiting patterns, which have their own treatment; and mechanical obstruction, which is a different problem needing a different operation. Both are excluded before any irreversible step is taken.
It is also honest to say what no procedure does. None of them cures gastroparesis. The diet continues afterwards. Benefit can wane over the first year. Non-response is the commonest disappointment, and it is discussed before the consent form is signed rather than afterwards. What the individualised risks are for your age, your nutrition, your diabetes control and your previous surgery is set out in writing at the consent discussion.

“It is one of the best hospitals for gastric problems, the staff is humble, service is good. My dad is getting treated by Harsh Sir, whenever we came here on regular check-ups or emergencies he has treated him according to the situation. Once we entered the premises of the hospital they just took over all your stress by doing what they do best. I will recommend to everyone with any gastric problem that this is your go-to place in an emergency.”

From the first consultation to recovery there are five stages, and at each one you are told what happens next and when.
Gastroparesis procedures are covered by most health insurance policies and by cashless arrangements at Apollo Hospital, Bhat — but insurers ask for evidence that medical treatment was properly tried first, so that record is assembled as part of the work-up rather than at the last minute.
What moves the estimate: which procedure is planned and whether it is done through the endoscope or by keyhole surgery; whether feeding access is placed at the same time; whether an implanted device is involved, which sits in a different bracket and is seldom funded; the room category; and the length of stay. The office prepares the pre-authorisation paperwork with the clinical justification and the documented medical trial attached, and seeks cashless approval before admission wherever the policy allows. Bring the policy document, your ID, previous records, imaging on disc as well as film, the emptying study and your current prescriptions.
No, and any surgeon who says otherwise is overselling it. A well-chosen procedure can reduce nausea, vomiting and early fullness enough to change daily life, but the diet continues afterwards, the benefit can fade over the first year, and a real minority of patients do not respond at all. That is said plainly before consent, not afterwards.
It does not. A study stopped at two hours misses a substantial share of genuine cases, which is why the standard test images through to four hours with a standardised solid meal. If your scan stopped early, it is incomplete rather than negative, and repeating it properly is usually the next step.
It can be, and it is one of the first things checked. The GLP-1 medicines slow gastric emptying as part of how they work, and opioid painkillers and several bladder, sleep and allergy medicines do the same. Reviewing and stopping the responsible drug, with your physician, resolves a meaningful number of referrals without any procedure.
As treatment, no — two randomised trials tested it and neither found benefit. At most it is an imperfect way of predicting who might respond to a proper outlet procedure. Where the real question is whether the outlet is tight, measuring how the pylorus opens during endoscopy answers it better.
They treat the same problem by different routes. G-POEM divides the outlet muscle from inside the stomach through the endoscope, with no cut on the abdomen and usually a night or two in hospital. A laparoscopic pyloroplasty widens the same outlet through keyhole surgery, takes a few days longer to recover from, and is the better choice when something else needs doing at the same operation — placing feeding access, for example.
Only if you cannot maintain nutrition by mouth — and it is usually temporary, intended to get you safely through a period of poor intake or to build you up before a procedure. It goes into the small bowel rather than the stomach, so it works even when the stomach does not, and your family is trained to look after it before you go home.
