The NYGA Difference: Clinical Excellence and Experience

Not all colonoscopies are the same

Our goal is always to offer our patients a better and more thorough colonoscopy to help reduce their risk of developing colorectal cancer.

The keys to a successful colonoscopy

- Experience,
- Expertise,
- Diligence
- Advanced imaging tools.

Each of the NYGA gastroenterologists has performed over 10,000 colonoscopies with polyp detection rates that consistently come in significantly above the national average.

In 2008, we identified and removed pre-cancerous polyps during 36.5% of the colonoscopies that we performed. Nationally, physicians, on average, only find polyps in 25% of the colonoscopies they perform on men and only 15% that they perform on women. We achieved our superior results with almost no complications¹.

High Detection Rates

While recent studies have shown polyp detection rates decreasing later in the day, NYGA showed itself to be consistent in polyp detection rates.

In an analysis of almost 1500 patients, morning and afternoon detection rates were virtually the same for total polyps (67% in the morning vs 66% in the evening), premalignant polyps (46% vs 47%), adenomatous polyps (41% vs 44%), sessile serrated polyps (8% vs 8%) and hyperplastic polyps (27% vs 24%). NYGA’s stable detection rates throughout the day can be attributed in part to the use of split-dose bowel preparation and moderated daily colonoscopist procedure loads.
