A colonoscopy is a procedure that allows Dr. Jing Tong to examine the entire length of your colon (large intestine) and rectum using a flexible, lighted tube called a colonoscope. This procedure is considered the gold standard for colon cancer screening and is the most effective way to detect and prevent colorectal cancer -- the third most common cancer in the United States.
During a colonoscopy, Dr. Tong can identify and remove precancerous growths called polyps before they have a chance to develop into cancer. This makes colonoscopy not just a diagnostic tool, but a potentially life-saving preventive procedure. The American Cancer Society recommends that adults at average risk begin regular colonoscopy screening at age 45.
As a Johns Hopkins trained gastroenterologist and one of the few US specialists licensed in therapeutic endoscopy, Dr. Tong brings exceptional expertise to every colonoscopy performed at our Flushing, Queens office. His advanced training enables him to handle complex cases, including the removal of large or difficult polyps that might otherwise require surgery.
Age 45+ for average-risk individuals
Blood in stool or on toilet paper
Persistent diarrhea or constipation
Family history of colon cancer or polyps
Positive stool test or imaging findings
Abdominal pain, weight loss, or anemia
The day before your colonoscopy, you will follow a clear liquid diet and take a prescribed bowel preparation solution to cleanse your colon. A clean colon is essential for accurate examination.
IV sedation is administered to ensure you are comfortable and relaxed throughout the procedure. Most patients sleep through the entire colonoscopy and feel no discomfort.
Dr. Tong carefully advances the colonoscope through your entire colon, examining the lining with high-definition imaging. He methodically inspects every fold and surface for polyps, inflammation, or other abnormalities.
If polyps are found, Dr. Tong removes them during the same procedure using specialized instruments -- a painless process called polypectomy. Tissue samples may also be collected for laboratory analysis.
After a brief recovery period of about 30 minutes, Dr. Tong will discuss his findings with you. You can resume normal activities the next day. Biopsy results are typically available within one week.
