Why have I been referred to an Advanced Interventional Endoscopist?

Advanced interventional endoscopy

Why was i referred?

You may have been referred because your condition, scan or previous endoscopy requires a more specialised type of investigation or treatment.

An advanced interventional endoscopist is a gastroenterologist with additional subspecialty training and experience in complex procedures that go beyond routine gastroscopy and colonoscopy.

In most instances, this means issues that previously required higher risk, more invasive approaches (include surgery) can be approached in a minimally invasive way. In other, it can mean issues causing symptoms or risk that cannot be seen on scans can be diagnosed and assessed in more detail.

Using techniques such as
EUS, ERCP, EMR and ESD, they can investigate and treat conditions involving the digestive tract, pancreas and bile ducts from inside the body—such as complex polyps, early cancers, bile duct stones, narrowing or blockages.

This specialty works closely with other doctors treating abdominal conditions. General gastroenterologists provide broad medical care for digestive conditions and routine diagnostic endoscopy such as gastroscopy or colonoscopy. A general gastroenterologist will refer conditions like advanced polyps, Barrett's oesophagus and conditions related to the pancreas and bile ducts for advanced endoscopy.

Surgeons also treat a broad range of abdominal conditions when surgery is required. A surgeon may refer you because a less invasive options is available or to help plan the best way for you to proceed with their treatment (such as establishing a diagnosis before surgery or managing condition arising after surgery).

Your referral does not necessarily mean that your condition is more serious; it means your referring doctor believes you may benefit from highly specialised expertise and, where appropriate, a minimally invasive treatment that may avoid, delay or complement surgery.

Quality in Endoscopy

Adenoma Detection Rate (ADR)What is your doctor’s Adenoma Detection Rate (ADR) and why should you care?

 
Adenoma detection rate, or ADR, is a numeric value that represents the percentage of times your gastroenterologist detects a precancerous polyp during screening colonoscopies. This number is considered a benchmark of quality and care, as it indicates how thorough your doctor will be during your examination.

Although gastroenterologists undergo the most extensive training in performing colonoscopies, their rates of polyp detection can vary significantly. When interviewing gastroenterologists to perform your procedure, look for a physician with an ADR of at least 25 percent in men and 15 percent in women. The higher the ADR, the better.


Research shows that for every 1% increase in a physician’s ADR, your risk of developing colon cancer over the next year decreases by 3%, and a 5% decrease in risk of a fatal interval cancer.

Conclusions of this study: the adenoma detection rate was inversely associated with the risks of interval colorectal cancer, advanced-stage interval cancer, and fatal interval cancer.

You may feel a little uneasy asking your potential doctor about providing an ADR, but rest assured that this is a reasonable request. Qualified gastroenterologists take pride in their hard-earned ADRs, and they will be happy to share this information with you. You should also enquire about your physician’s average withdrawal time, which is the amount of time it takes to remove the scope from the colon. You want a gastroenterologist with an average withdrawal time of at least six minutes.

 

Finding the right gastroenterologist may require a bit of courage and assertiveness, but it is well worth the effort. Make a list of questions to ask when interviewing potential physicians, and be sure to include ADR and average withdrawal time. A high-quality physician is the key to a thorough examination and a future without colon cancer.

 

Why is the Average Withdrawal Time important?

 

Adenoma detection was strongly associated with longer withdrawal times: endoscopists whose withdrawal times were more than 6 minutes detected more than twice as many patients with adenomas that were 1cm or larger in size.

Background and Aims
Current post-polypectomy guidelines set intervals based solely on features of resected polyps. Despite the well-known inverse relationship between both adenoma detection rate (ADR) and proximal serrated polyp detection rate (PSPDR) with post-colonoscopy colorectal cancers (PCCRCs), both quality indicators are not considered when determining surveillance intervals.

Methods
We used colonoscopy data from 2014 to 2020 performed for a positive fecal immunochemical test in the Dutch colorectal cancer screening program. Individuals were categorized into having high-risk polyps or no/low-risk polyps resected. The association between 3-year PCCRC-risk and presence of high-risk polyps and either ADR or PSPDR was studied with Cox proportional hazard regression. Secondly, endoscopists were categorized into low/medium/high ADR and PSPDR to enable stratified analysis.

Results
A total of 239,217 individuals were included; 74,289 had high-risk polyps resected at baseline and 202 had PCCRC within the subsequent 3 years. Presence of high-risk polyps was not associated with PCCRC-risk (hazard ratio [HR], 1.00; 95% confidence interval [CI], 0.75–1.35), whereas ADR and PSPDR showed a strong association with PCCRC (per point increase HR, 0.94; 95% CI, 0.92–0.96; HR, 0.92; 95% CI, 0.89–0.95, respectively). For individuals with no/low-risk polyps but examined by endoscopists with low ADR, the HR of PCCRC was 2.11 (95% CI, 1.21–3.65), as compared with individuals with high-risk polyps but examined by endoscopists with high ADR.

Conclusions
An individual’s PCCRC risk in the initial years is primarily influenced by endoscopist performance, rather than the presence of high-risk polyps. To reduce PCCRCs, besides ensuring appropriate surveillance intervals, it is crucial to monitor and audit endoscopist quality indicators.
