AGA Tech Summit: Bridging the gap between innovation industry and gastroenterologists
-
12/22/2023
Medicine is transforming at a remarkable pace. It is therefore imperative for the future of the field that physicians understand innovation and collaborate with industry partners. Innovation can be defined as invention, adoption, and diffusion.1 During my training in gastroenterology and advanced fellowships, I learned about multiple endoscopic tools and techniques and became familiar with industry names that I frequently encountered in the endoscopy unit or clinic.
The American Gastroenterological Association (AGA) Tech Summit was my initial experience in learning more about the role of industry in driving our field forward and the journey of a product from concept to market. I was nominated to attend the AGA Tech Summit Fellows Program by my advanced endoscopy fellowship program director. A total of 22 fellows from around the United States at various stages of their training and interests in the field of gastroenterology and hepatology were selected for the program through an application process. The program included registration, travel, and accommodations to attend the AGA Tech Summit and Fellows Immersion Day at Medtronic.

The first event in the program was a visit to the Medtronic Santa Clara office, where our initial stop was at the research and development lab. We were introduced to design and biomedical engineers who reviewed with us the extensive testing that devices and endoscopy equipment undergo before coming to the market. These labs have a heavy focus on prototyping and experimentation and exist to promote in-house innovation and inventions.

AGA Tech Summit Fellows
During the day, we met physicians who shared their journeys on how they developed and advanced their careers in partnership with industry. Our visit also included a session with the business development and strategy manager at Medtronic, who discussed strategy and steps involved in product development — from the inception of an idea, institutional policies, and patents, to industry collaboration, and finally to successful commercialization. During medical school and training, we are focused on appropriately learning and applying medical knowledge to clinical care. The Medtronic Fellows Immersion Day experience offered a different perspective and showed other ways by which clinical knowledge and experience can be used to make an impact, in collaboration with industry and stakeholders. It also highlighted alternative career paths for medical professionals. The evening concluded with a meet and greet with the AGA Center for GI Innovation & Technology (CGIT) members and leadership.

A presentation at the AGA Tech Summit
The AGA Tech Summit was unlike any conference I have been to in my 13 years of training in medicine (which included mostly clinically focused scientific meetings). Sessions involved ergonomics, applications of artificial intelligence, advances in imaging, environmental endoscopy, the role of the FDA, and innovations around the world. The audience included but was not limited to industry executives, AGA CGIT leadership, physician innovators, gastroenterologists, venture capitalists, and others. Attendees represented the diversity of our field in terms of organizational structures and backgrounds. This resulted in an opportunity to hear and learn different perspectives about products, emerging technology, and the costs involved for physicians, industry, and patients.
The final session of the summit, the AGA Shark Tank, was perhaps the most intriguing one of all. The session showcased landscape-changing technology to AGA investors and venture capitalists. The participants presented their own pitches and faced the sharks (judges). The winner received additional funding, tailored guidance from the AGA CGIT committee, partnering opportunities with interested parties, and the opportunity to represent AGA Shark Tank at the Digestive Disease Week (DDW).
The AGA Tech Summit Fellows Program is a learning platform that not only helps you find your niche in the world of GI innovation but also equips you with resources and connections to make an impact. It is also a great way to infuse new ideas into your practice or research. As healthcare professionals, we must create a culture where innovation can flourish, and where staff and patients feel empowered to contribute to the innovation process and help make change happen — to me, the AGA Tech Summit is one such avenue.

The guidelines emphasize four-hour gastric emptying studies over two-hour testing. How do you see this affecting diagnostic workflows in practice?
Dr. Staller: Moving to a four-hour solid-meal scintigraphy will actually simplify decision-making. The two-hour reads miss a meaningful proportion of delayed emptying; standardizing on four hours reduces false negatives and the “maybe gastroparesis” purgatory that leads to repeat testing. Practically, it means closer coordination with nuclear medicine (longer slots, consistent standardized meal), updating order sets to default to a four-hour protocol, and educating front-line teams so patients arrive appropriately prepped. The payoff is fewer equivocal studies and more confident treatment plans.
Metoclopramide and erythromycin are the only agents conditionally recommended for initial therapy. How does this align with what is being currently prescribed?
Dr. Staller: This largely mirrors real-world practice. Metoclopramide remains the only FDA-approved prokinetic for gastroparesis, and short “pulsed” erythromycin courses are familiar to many of us—recognizing tachyphylaxis limits durability. Our recommendation is “conditional” because the underlying evidence is modest and patient responses are heterogeneous, but it formalizes what many clinicians already do: start with metoclopramide (lowest effective dose, limited duration, counsel on neurologic adverse effects) and reserve erythromycin for targeted use (exacerbations, bridging).
Several agents, including domperidone and prucalopride, received recommendations against first-line use. How will that influence discussions with patients who ask about these therapies?
Dr. Staller: Two points I share with patients: evidence and access/safety. For domperidone, the data quality is mixed, and US access is through an FDA IND mechanism; you’re committing patients to EKG monitoring and a non-trivial administrative lift. For prucalopride, the gastroparesis-specific evidence isn’t strong enough yet to justify first-line use. So, our stance is not “never,” it’s just “not first.” If someone fails or cannot tolerate initial therapy, we can revisit these options through shared decision-making, setting expectations about benefit, monitoring, and off-label use. The guideline language helps clinicians have a transparent, evidence-based conversation at the first visit.
The guidelines suggest reserving procedures like G-POEM and gastric electrical stimulation for refractory cases. In your practice, how do you decide when a patient is “refractory” to medical therapy?
Dr. Staller: I define “refractory” with three anchors.
1. Adequate trials of foundational care: dietary optimization and glycemic control; an antiemetic; and at least one prokinetic at appropriate dose/duration (with intolerance documented if stopped early).
2. Persistent, function-limiting symptoms: ongoing nausea/vomiting, weight loss, dehydration, ER visits/hospitalizations, or malnutrition despite the above—ideally tracked with a validated instrument (e.g., GCSI) plus nutritional metrics.
3. Objective correlation: delayed emptying on a standardized 4-hour solid-meal study that aligns with the clinical picture (and medications that slow emptying addressed).
At that point, referral to a center with procedural expertise for G-POEM or consideration of gastric electrical stimulation becomes appropriate, with multidisciplinary evaluation (GI, nutrition, psychology, and, when needed, surgery).
What role do you see dietary modification and glycemic control playing alongside pharmacologic therapy in light of these recommendations?
Dr. Staller: They’re the bedrock. A small-particle, lower-fat, calorie-dense diet—often leaning on nutrient-rich liquids—can meaningfully reduce symptom burden. Partnering with dietitians early pays dividends. For diabetes, tighter glycemic control can improve gastric emptying and symptoms; I explicitly review medications that can slow emptying (e.g., opioids; consider timing/necessity of GLP-1 receptor agonists) and encourage continuous glucose monitor-informed adjustments. Pharmacotherapy sits on top of those pillars; without them, medications will likely underperform.
The guideline notes “considerable unmet need” in gastroparesis treatment. Where do you think future therapies or research are most urgently needed?
Dr. Staller: I see three major areas.
1. Truly durable prokinetics: agents that improve emptying and symptoms over months, with better safety than legacy options (e.g., next-gen motilin/ghrelin agonists, better-studied 5-HT4 strategies).
2. Endotyping and biomarkers: we need to stop treating all gastroparesis as one disease. Clinical, physiologic, and microbiome/omic signatures that predict who benefits from which therapy (drug vs G-POEM vs GES) would transform care.
3. Patient-centered trials: larger, longer RCTs that prioritize validated symptom and quality-of-life outcomes, include nutritional endpoints, and reflect real-world medication confounders.
Our guideline intentionally highlights these gaps to hopefully catalyze better trials and smarter referral pathways.
