Endoscopic Sleeve Gastroplasty

Endoscopic sleeve gastroplasty is a procedure performed entirely through the mouth. A flexible endoscope carries a suturing device into the stomach, and a series of full thickness sutures is placed along the greater curvature. Drawing those sutures together folds the stomach inward, so the interior becomes a narrower tube.

Two things follow from that. The stomach holds less at one sitting, and it empties more slowly, which changes the fullness signals the stomach sends after a meal. Neither effect depends on removing anything.

There are no incisions in the abdominal wall. No part of the stomach is cut away. Nothing is implanted and nothing is left behind other than sutures. The stomach is reshaped from the inside, and the reshaping is the point.

A laparoscopic sleeve gastrectomy is an operation. Small incisions are made in the abdomen, and a portion of the stomach is separated and permanently removed. It is a well established operation with decades of data behind it, and for many people it is the right choice.

ESG works on the same organ toward a similar goal by a different route. The stomach is folded rather than cut, the access is through the mouth rather than the abdominal wall, and no tissue leaves the body. Recovery is generally quicker, and the procedure does not close the door on other options later.

The tradeoff is honest and worth stating plainly. The surgical sleeve has a longer track record and, in general, produces a larger and more durable metabolic effect. ESG asks less of the body up front and delivers a more moderate change. Which of those tradeoffs suits you is exactly what a consultation is for.

• ESG: no incisions, no tissue removed, sutured from inside, same day discharge in most cases
• Surgical sleeve: laparoscopic incisions, part of the stomach removed permanently, larger and longer studied effect
• Both act on the stomach and on the hormonal signals tied to it
• Both require the same nutritional and follow up commitment to hold results

ESG is often considered by people whose metabolic disease is real but who do not meet the usual thresholds for an operation, or who meet them and do not want an operation. It is also considered by people who cannot safely undergo abdominal surgery, and by people who want an option that removes nothing.

Candidacy is not decided by a single number. It is decided by your metabolic picture, your medical history, your prior abdominal surgery, your reflux status, your medications, and what you actually want out of treatment. Someone with severe reflux or a significant hiatal hernia may need that addressed first, because folding the stomach does not fix a failing valve.

It is also worth saying who it does not suit. If your metabolic disease is advanced and you are seeking the largest and most durable change available, an operation deserves serious discussion rather than being avoided by default. Nobody is served by choosing the smaller intervention and then being disappointed by a smaller result.

Nothing is scheduled before the evaluation is complete. That means a full history, a review of your medications including any GLP-1 therapy, and laboratory work that looks at the metabolic picture rather than a single value.

Upper endoscopy is performed before ESG. The stomach and esophagus are inspected directly, hiatal hernia and inflammation are identified, and anything that needs treating first is found before rather than during the procedure.

If reflux symptoms are prominent, reflux testing is added. Reflux is treated here as a condition in its own right, not an afterthought to metabolic care, and it changes the plan when it is present.

• Full history, medication review, and metabolic laboratory work
• Upper endoscopy to inspect the stomach and esophagus
• Reflux evaluation when symptoms warrant it
• Nutrition consultation, before rather than after
• A clear conversation about what the procedure can and cannot do

You arrive having had nothing to eat or drink for the period specified in your instructions. An empty stomach is not a formality here, it is a safety requirement and the single most common reason a procedure is postponed.

The procedure is performed under anesthesia, so you are asleep and feel nothing. The endoscope passes through the mouth. There is no incision anywhere on the body, which means no wound care, no scar, and no abdominal wall to heal.

The suturing itself takes place under direct vision. A pattern of full thickness sutures is placed and then cinched, and the stomach shape is checked as the pattern builds. When the shape is right, the scope comes out.

You wake in recovery and are monitored for a few hours. Most people go home the same day. You will need someone to drive you, and you should plan not to work, sign anything, or make decisions that day.

The first several days ask for patience. Cramping, nausea, and a sense of fullness that arrives almost immediately are common and expected as the stomach adjusts to being folded. Medication is provided for nausea, and it is used rather than endured.

Diet advances in stages, beginning with clear liquids, moving to full liquids, then to soft foods, then to regular textures over a period of weeks. The stages are not arbitrary. They protect the suture line while it settles and they retrain how you eat.

Most people return to desk work within a few days, and to normal activity quickly, because there is no abdominal wall incision to protect. That is the practical advantage of an incisionless approach and it is a real one.

Follow up is scheduled, frequent early, and it includes nutrition. Anyone who tells you a procedure works without follow up is selling something.

No number is promised here, and any provider quoting you a guaranteed figure should be treated with suspicion. Results vary between people, and the honest predictors are consistent across the evidence: engagement with nutrition follow up, protein and meal structure, physical activity, sleep, and treatment of the other metabolic conditions in the picture.

The procedure changes the stomach. It does not by itself change the hormonal environment that produced the disease, which is why ESG is offered inside a program rather than as a standalone event. The stomach is the lever. The program is what moves it.

Results can also be undone. The stomach is a muscular organ and it responds to what is repeatedly asked of it. Sustained overfilling works against the reshaping. This is said plainly before the procedure rather than apologetically afterward.

GLP-1 medications have changed the landscape and the practice does not treat them as competition. They work on appetite signaling and metabolic regulation. ESG works on the capacity and emptying of the stomach. Those are different mechanisms, and they can be complementary.

Some people come having done well on medication and wanting a structural change so their result does not depend indefinitely on a prescription. Some come having been unable to tolerate the medication. Some use both together, with the medication managed by the prescribing physician while the procedure addresses the mechanical side.

There is one practical point that matters for safety. GLP-1 medications slow stomach emptying, and that affects anesthesia planning. Your full medication list, including dose and timing, has to be shared before scheduling. Instructions about holding medication are given individually and they are not optional.

ESG is frequently pursued as a self pay procedure. Coverage varies and is discussed individually rather than assumed, and no price appears on this page because a real figure depends on your evaluation.

Availability is limited in Colorado, and that is a genuine reason people travel for it. The evaluation is the starting point, and it is where candidacy, alternatives, and expectations are all put on the table at once.

This page is educational information, not medical advice. What is right for you is decided in consultation, after a review of your history, your symptoms, and your testing.
