We can only imagine what ancient Romans thought of a physician sticking a device into their bodies to see what was going on inside of them. Yet, that actually may have occurred. In fact, a few years ago, archaeologists discovered a device that looks like an endoscope in the ruins of Pompeii, the Italian city destroyed in 79 AD by an eruption of Mount Vesuvius.
We can probably deduce two things from this bit of knowledge. First, whatever patients say about getting an endoscopy these days it was likely far less "hellish" or "torturous" than it was centuries ago. And second, doctors – even those as primitive as found in ancient Rome – have long known that it's vital to get a peek at what is going on inside their patients.
Today, endoscopy is one of the most common outpatient procedures conducted in the United States with nearly18 million procedures performed annually. To do it, a doctor inserts a flexible tube with a light and camera attached to it into your digestive system.
But as important as these examinations are in detecting cancer, ulcers and other digestive diseases, they were ground to a halt by the emergence of COVID-19. In April, for instance, gastrointestinal endoscopy procedures plunged 93% below normal volume in the Veterans Administration ÈËÆÞÖгöÊÓƵcare System which serves more than 6 million veterans nationwide. Similarly, ÈËÆÞÖгöÊÓƵ of Utah ÈËÆÞÖгöÊÓƵ performed 80% fewer endoscopies in April than normal.
Yet, while this presents a serious concern, it is also an opportunity for doctors to evaluate how and when these procedures should be done, according to an associate professor of gastroenterology at U of U ÈËÆÞÖгöÊÓƵ and lead author of a recent commentary of the impact of COVID-19 on access to endoscopic procedures via the VA ÈËÆÞÖгöÊÓƵcare System.
"Losing access to most endoscopies as a result of the COVID-19 pandemic has severely hampered our ability to detect, diagnose and treat many digestive diseases," says Gawron, who is also a staff physician at the Salt Lake City VA. "On the other hand, this unexpected pause in doing these procedures has given us an unprecedented opportunity to step back to reconsider if and when endoscopies are necessary and explore whether there may be effective alternatives to their use."
The commentary appears in
Within the VA, estimates suggest that about 64,000 endoscopic examinations have been postponed or deferred since the onset of COVID-19. Gawron and colleagues suspect that this figure will continue to surge as the pandemic continues, potentially affecting up to 400,000 veterans who undergo it annually. This drop could also affect the U of U ÈËÆÞÖгöÊÓƵ gastroenterology program since many of its medical students receive endoscopy training at the Salt Lake VA Hospital, Gawron says
But, as Gawron and his colleagues point out in their commentary, the VA has adopted several strategic approaches to mitigate the disruption of endoscopic procedures; similar strategies were adopted by U of U ÈËÆÞÖгöÊÓƵ and serve as a model for other medical institutions:
Offering patients non-invasive substitutes: Instead of endoscopy, VA doctors have turned to non-invasive ways to screen colon cancer such as fecal immunochemical testing (FIT), which detects hidden blood in the stool (an early warning sign of cancer), and is another recommended test for colon cancer screening.
Finetuning triage: The VA has prioritized who receives an endoscopy. These range from Priority 1 patients, who have trouble swallowing, rectal bleeding or other symptoms and need immediate examination, to priority 4 patients who are healthy but are due for a cancer-screening endoscopy this year.
Curbing overuse: Previous research has shown that up to 30% of colonoscopies conducted in the VA and non-VA ÈËÆÞÖгöÊÓƵcare systems may be done too early or may not be necessary, Gawron says. As a result, the VA is aggressively adopting new colon polyp surveillance guidelines for when and how often procedures are actually needed.
However, if you do have gastrointestinal symptoms it is vital that you consult a physician as soon as possible, Gawron says.
"Patients, whether they are coming to the VA or U of U ÈËÆÞÖгöÊÓƵ should feel safe to seek necessary care if you have concerning signs or symptoms," he says. "The longer you delay, the more potential for harm."
