State-of-the-art amenities. We pride ourselves on creating a hassle-free and comfortable experience for our patients and their guests. You’ll get in and out faster. Interactive displays in your pre-/post-procedure room allow you and your guest to watch TV and access information. Convenient, covered parking keeps you dry no matter the weather. Plus, our center offers a streamlined design for optimum infection control.
Innovative procedures. Our endoscopists offer our patients the most advanced, up-to-date and specialized endoscopic services. We use the latest techniques and technologies, including artificial intelligence (AI) platforms, to increase colon polyp detection rates.
Easier colonoscopy prep. Having a colonoscopy no longer means drinking a gallon of thick, foul-tasting liquid. At Northwest Endoscopy Center, we recommend a gentler prep that includes a mix of MiraLAX and Gatorade taken several hours apart. It’s better tasting and easier for most people to tolerate.

Colonoscopy
Colonoscopy remains the “gold standard” for finding colorectal cancer in its earliest, most treatable stages. The American Cancer Society (ACS) now recommends that adults start screening for colorectal cancer at age 45. This is due in part to ACS data that shows a notable rise in colorectal cancer diagnoses among people younger than age 50.
We recommend colonoscopy as a preferred screening test over other types of screenings because colonoscopy:
- Is associated with reduced incidence and mortality from colorectal cancer
- Has the highest sensitivity for finding colorectal cancer and precancerous polyps
- Allows for the detection and treatment of colon cancer in the same procedure
By comparison, stool DNA tests like Cologuard have a much lower sensitivity for detecting precancerous lesions (42.4% for Cologuard vs. 95% for colonoscopy). If you have a positive Cologuard test, you will still need a colonoscopy for further evaluation. Plus, Cologuard has a reported false positive rate of 13%, meaning a positive test could result in a negative colonoscopy. Cologuard is only recommended for people at average risk, so, if you’ve had a colon polyp or have a family member with colon cancer, we recommend you get a colonoscopy.
During a colonoscopy, an endoscopist will use an endoscope (a thin tube with a light and camera at the end) to examine your colon and rectum for polyps and other signs of colon or rectal cancer. Colonoscopy is the only procedure that can both diagnose and treat colorectal cancer. You should get a colonoscopy at least once every 10 years, and more often if you have specific risk factors.
Endoscopy
In addition to colonoscopy, the experts at Northwest Endoscopy Center perform the following procedures:
- Upper endoscopy (EGD) to examine the upper part of your digestive system for digestive issues.
- Endoscopic retrograde cholangiopancreatography (ECRP) to examine your bile and pancreas ducts for jaundice or pancreatitis.
- Per-oral endoscopic myotomy (POEM) to look for signs of a swallowing disorder called achalasia.
- Radiofrequency ablation to treat abnormal tissue and pre-cancerous growths in the digestive tract.
- Esophageal and colon stenting to treat conditions that narrow the digestive tract and/or colon.
- Endoscopic mucosal resections/submucosal dissections to remove abnormal tissue or pre-cancerous growths in the lining of the digestive tract.
- Endoscopic suturing and clipping to close tears in the digestive tract.
- GI Genius™ AI to enhance detection of polyps in colonoscopies.
- Endoscopic revisional bariatric procedures to modify or alter a previous gastric sleeve or gastric bypass surgery.
- Endoscopic feeding tube placement to help ensure patients who need a feeding tube can receive appropriate nutrients.
- Foreign body removal to remove objects that have been swallowed or that are stuck in your digestive tract.
- Stricture dilation to widen narrowed areas in the esophagus.

Frequently Asked Questions
When should I have my first colonoscopy?
The American Cancer Society recommends that all adults should start screening for colon cancer at age 45. Colonoscopy is the preferred screening for colorectal cancer because it can both diagnose and treat cancer. During a colonoscopy, an endoscopist will examine your colon and rectum. If any polyps are found, they can be removed in the same procedure and then tested for potential signs of cancer.
Why have a colonoscopy instead of Cologuard?
Colonoscopy remains the preferred method of colorectal cancer screening. A colonoscopy is proven to reduce both the incidence of and mortality from colorectal cancer. It also allows for the detection and treatment of colon cancer in the same procedure. The sensitivity for detecting precancerous lesions is 95% for colonoscopy vs. just 42.4% for Cologuard. Additionally, Cologuard has a false positive rate of 13%. If you have a positive Cologuard test, you will still need to get a colonoscopy. Cologuard is only for people at average risk, so people with a personal or family history of polyps or colon cancer will need a colonoscopy.
Is colonoscopy prep at Northwest Endoscopy Center easier than I remember?
If you remember the days of drinking a gallon of hard-to-swallow, bad-tasting liquid before a colonoscopy, you’ll be pleasantly surprised. The endoscopists at Northwest Endoscopy Center use a gentler colonoscopy prep that includes a mixture of MiraLAX and Gatorade. This mix is easier to tolerate for most people and tastes a whole lot better than the preps of the past.
What’s the best place for a colonoscopy or endoscopy in North Idaho?
When it comes to colonoscopies and endoscopies, Northwest Endoscopy Center is designed for optimal patient privacy and comfort. The 8,650-square-foot facility includes two spacious procedure rooms, one exam room, and eight pre-operative and post-anesthesia care unit bays. The center’s layout is friendly and private. Each room has large entertainment screens and privacy curtains. Patients will stay in a private pre- and post-operative procedure room. One guest or family member is allowed to accompany patients.
How has AI changed colonoscopies in the Inland Northwest?
Endoscopists at Northwest Endoscopy Center use the GI Genius™ Intelligent Endoscopy Module during colonoscopies. Created by Medtronic, GI Genius is a computer-aided polyp detection system powered by artificial intelligence (AI). The system provides enhanced visualization, allowing specialists to see harder-to-find polyps and other signs of colorectal cancer.
