Reducing Environmental Effects
In recent waste audits of endoscopy rooms, providers generate 1-3 kg of waste per procedure, which would fill 117 soccer fields to a depth of 1 m, based on 18 million procedures in the United States per year. This waste comes from procedure-related equipment, administration, medications, travel of patients and staff, and infrastructure with systems such as air conditioning. Taking steps toward a green practice can reduce waste and the carbon footprint of healthcare.
“When we think about improving colonoscopy performance, the goal is to prevent colon cancer death, but when we expand that, we have to apply sustainable practices as a domain of quality,” said Heiko Pohl, MD, professor of medicine at the Geisel School of Medicine at Dartmouth in Hanover, New Hampshire, and a gastroenterologist at White River Junction VA Medical Center in White River Junction, Vermont.
The GI Multisociety Strategic Plan on Environmental Sustainability suggests a 5-year initiative to improve sustainability and reduce waste across seven domains — clinical setting, education, research, society efforts, intersociety efforts, industry, and advocacy.

For instance, clinicians can take the biggest step toward sustainability by avoiding unneeded colonoscopies, Dr. Pohl said, noting that between 20% and 30% aren’t appropriate or indicated. Instead, practitioners can implement longer surveillance intervals, adhere to guidelines, and consider alternative tests, such as the fecal immunochemical test, fecal DNA, blood-based tests, and CT colonography, where relevant.
Clinicians can also rethink their approach to resection, such as using a snare first instead of forceps to reduce single-instrument use, using clip closure only when it’s truly indicated, and implementing AI-assisted optical diagnosis to help with leaving rectosigmoid polyps in place.
In terms of physical waste, practices may also reconsider how they sort bins and biohazards, looking at new ways to dispose of regulated medical waste, sharps, recyclables, and typical trash. Waste audits can help find ways to reduce paper, combine procedures, and create more efficient use of endoscopy rooms.
“We are really in a very precarious situation,” Dr. Pohl said. “It’s our generation that has a responsibility to change the course for our children’s and grandchildren’s sake.”
AI for Quality And Efficiency
Moving forward, AI tools will likely become more popular in various parts of GI practice, by assisting with documentation, spotting polyps, tracking mucosal surfaces, providing optical histopathology, and supervising performance through high-quality feedback.
“Endoscopy has reached the limits of human visual capacity, where seeing more pixels won’t necessarily improve clinical diagnosis. What’s next for elevating the care of patients really is AI,” said Jason B. Samarasena, MD, professor of medicine and program director of the interventional endoscopy training program at the University of California Irvine in Irvine, California.
As practices adopt AI-based systems, however, clinicians should be cautious about a false sense of comfort or “alarm fatigue” if bounding boxes become distracting. Instead, new tools need to be adopted as a “physician-AI hybrid,” with the endoscopist in mind, particularly if helpful for performing a better exam by watching withdrawal time or endoscope slippage.

“In real-world practice, this is being implemented without attention to endoscopist inclination and behavior,” he said. “Having a better understanding of physician attitudes could yield more optimal results.”
Notably, AI-assisted tools should be viewed akin to spell-check, which signals to the endoscopist when to pay attention and double-check an area — but primarily relies on the expert to do a high-quality exam, said Aasma Shaukat, MD, professor of medicine and director of GI outcomes research at the NYU Grossman School of Medicine, New York City.
“This should be an adjunct or an additional tool, not a replacement tool,” she added. “This doesn’t mean to stop doing astute observation.”

Future tools show promise in terms of tracking additional data related to prep quality, cecal landmarks, polyp size, mucosa exposure, histology prediction, and complete resection. These automated reports could also link to real-time dashboards, hospital or national registries, and reimbursement systems, Dr. Shaukat noted.
“At the end of the day, our interests are aligned,” she said. “Everybody cares about quality, patient satisfaction, and reimbursement, and with that goal in mind, I think some of the tools can be applied to show how we can achieve those principles together.”
Dr. Jacobson, Dr. Kaltenbach, Dr. Keswani, Dr. Pohl, Dr. Samarasena, and Dr. Shaukat reported no relevant financial relationships.
