The Strategic Necessity of Combined GI Endoscopy

Health systems are moving toward consolidating gastrointestinal procedures to manage a specialist shortage projected to reach nearly 1,400 gastroenterologists by 2037. Combined upper and lower GI endoscopy is becoming a strategic necessity, yet the clinical execution remains uneven. While patients view the session as one event, it remains two distinct clinical tasks: an esophagogastroduodenoscopy for the upper tract and a colonoscopy for the lower.

The current approach to combined procedures is driven by the colonoscopy. Because the patient is already present for colorectal cancer screening, the upper GI exam is often added as a secondary task. This sequencing creates a disparity in quality standards. Lower GI care benefits from decades of established infrastructure, including standardized metrics and proven AI-assisted detection. A 2024 meta-analysis of 28 randomized controlled trials involving nearly 24,000 patients found a 20% increase in adenoma detection rate and a 55% decrease in adenoma miss rate with AI-assisted colonoscopy.

Upper GI care lacks this same level of scrutiny. The clinical task in the upper tract involves ensuring complete coverage across complex folds and anatomical landmarks, rather than finding a specific target on a uniform surface. This gap in examination has a documented cost. In 69% of missed upper GI cancer cases, the endoscopist had already recorded an abnormality at the exact site where cancer was later diagnosed. The area was not invisible; it was simply not examined with sufficient care.

The consequences of this disparity are measurable. Upper GI cancer miss rates remain above 8% for esophageal and gastric cancers, with some estimates reaching 11.3%.

The shift toward combined procedures means health systems cannot treat the upper GI exam as a secondary task. If the industry is to solve the specialist shortage, it must apply the same rigorous, AI-driven benchmarks to the upper GI tract that have already transformed colonoscopy.

How can health systems ensure that the efficiency of combined procedures does not come at the expense of upper GI diagnostic accuracy?
