Advanced diagnostic and therapeutic gastroenterology procedures
Colonoscopy
What It Is
A colonoscopy is a procedure that allows your gastroenterologist to examine the entire length of the large intestine (colon) using a thin, flexible tube equipped with a camera. It is the gold standard for detecting colon polyps, colorectal cancer, and other abnormalities in the colon and rectum.
Why It's Done
Colonoscopies are recommended for routine colorectal cancer screening starting at age 45, evaluation of gastrointestinal symptoms such as rectal bleeding, chronic diarrhea, or unexplained abdominal pain, and surveillance for patients with a history of polyps or inflammatory bowel disease.
What to Expect
The procedure typically takes 30 to 60 minutes. You will receive sedation to ensure comfort. A flexible scope is gently inserted through the rectum, and the doctor examines the colon lining in real time. If polyps are found, they can be removed during the same session.
Preparation Tips
- Follow the prescribed bowel preparation instructions carefully
- Consume only clear liquids the day before the procedure
- Arrange for someone to drive you home after the procedure
- Inform your doctor of all medications, especially blood thinners
- Avoid solid foods for at least 24 hours before the exam
Upper Endoscopy (EGD)
What It Is
An upper endoscopy, also known as esophagogastroduodenoscopy (EGD), is a procedure that examines the lining of the esophagus, stomach, and the first part of the small intestine (duodenum). A thin, flexible endoscope with a light and camera is passed through the mouth to visualize these areas.
Why It's Done
This procedure is used to investigate symptoms such as persistent heartburn, difficulty swallowing, nausea, vomiting, upper abdominal pain, or unexplained weight loss. It can also diagnose conditions like ulcers, GERD, Barrett's esophagus, celiac disease, and upper GI tumors.
What to Expect
The procedure usually takes 15 to 30 minutes. You will receive sedation for comfort. The endoscope is gently guided through the mouth and throat. Tissue biopsies may be taken for further analysis, and therapeutic treatments such as dilation can be performed if needed.
Preparation Tips
- Do not eat or drink for 6 to 8 hours before the procedure
- Discuss current medications with your doctor beforehand
- Arrange transportation home as sedation effects may linger
- Wear comfortable, loose-fitting clothing
- Remove dentures or dental appliances before the procedure
Colon Cancer Screening
What It Is
Colon cancer screening encompasses a range of tests designed to detect colorectal cancer early, when it is most treatable. Screening methods include colonoscopy, stool-based tests (FIT, Cologuard), CT colonography, and flexible sigmoidoscopy. Our team helps determine the most appropriate screening approach based on your risk factors.
Why It's Done
Colorectal cancer is the third most common cancer in the United States, but early detection through screening can significantly reduce mortality. Screening is recommended for all adults beginning at age 45, or earlier for those with a family history of colorectal cancer, personal history of polyps, or inflammatory bowel disease.
What to Expect
The screening process begins with a risk assessment and discussion of your options. Depending on the method chosen, preparation and procedure times vary. Colonoscopy remains the most comprehensive screening tool, while stool-based tests offer a less invasive initial option with follow-up colonoscopy if results are abnormal.
Preparation Tips
- Schedule your screening at age 45 or discuss earlier with your doctor
- Share your complete family medical history with your provider
- Follow preparation instructions specific to the chosen screening method
- Keep regular follow-up appointments as recommended
- Report any changes in bowel habits or rectal bleeding promptly
Sigmoidoscopy
What It Is
A sigmoidoscopy is a diagnostic procedure that examines the lower portion of the colon, specifically the sigmoid colon and rectum. Using a short, flexible, lighted tube (sigmoidoscope), your doctor can visualize the lining of the lower colon to detect abnormalities such as polyps, inflammation, or tumors.
Why It's Done
Sigmoidoscopy is recommended for evaluating symptoms localized to the lower colon, including rectal bleeding, chronic diarrhea, lower abdominal pain, and changes in bowel habits. It may also be used as a screening tool for colorectal cancer in certain situations or when a full colonoscopy is not feasible.
What to Expect
The procedure takes approximately 15 to 20 minutes and may be performed with or without sedation. The sigmoidoscope is gently inserted through the rectum, and the doctor examines the last third of the colon. Small tissue samples (biopsies) can be taken, and polyps may be removed during the procedure.
Preparation Tips
- Complete the prescribed enema or bowel prep the morning of the procedure
- A full bowel preparation may not be required unlike a colonoscopy
- You may be able to drive yourself home if sedation is not used
- Eat a light meal the evening before the procedure
- Discuss any concerns about discomfort with your medical team
Bariatric Endoscopic Procedures
What It Is
Bariatric endoscopic procedures are minimally invasive weight-loss interventions performed through the mouth using an endoscope, eliminating the need for surgical incisions. These include intragastric balloon placement, endoscopic sleeve gastroplasty (ESG), and aspiration therapy. They offer an alternative for patients who may not qualify for or prefer to avoid traditional bariatric surgery.
Why It's Done
These procedures are indicated for patients with a BMI between 30 and 40 who have not achieved adequate weight loss through diet and exercise alone. They are also suitable for patients who are not candidates for surgical weight-loss options or who prefer a less invasive approach with shorter recovery times.
What to Expect
Procedures are typically performed under general anesthesia and take 30 to 90 minutes depending on the technique. Most patients can go home the same day or the following day. Recovery is generally faster than surgical alternatives, and patients work closely with a dietitian and support team for sustained results.
Preparation Tips
- Complete a comprehensive evaluation including blood work and imaging
- Follow a pre-procedure diet as directed by your care team
- Attend all required nutrition and behavioral counseling sessions
- Arrange for someone to drive you home after the procedure
- Plan for a liquid diet for the first few days post-procedure
Frequently Asked Questions
Common questions about our gastroenterology procedures
How do I prepare for a colonoscopy?
Preparation typically involves a special bowel-cleansing solution the day before the procedure, a clear liquid diet, and avoiding solid foods. Your doctor will provide detailed preparation instructions tailored to your specific situation. Following the prep instructions carefully is crucial for a successful procedure.
Are these procedures painful?
Most gastroenterology procedures are performed under sedation, so you should not feel pain during the procedure. You may experience mild discomfort such as bloating or cramping afterward, which typically resolves quickly. Our team prioritizes your comfort throughout the entire process.
How long does recovery take?
Recovery varies by procedure. For colonoscopies and upper endoscopies, most patients resume normal activities the next day. Bariatric endoscopic procedures may require a few days of recovery. Your doctor will provide specific post-procedure guidelines and follow-up care instructions.
Will my insurance cover these procedures?
Many gastroenterology procedures, especially screening colonoscopies, are covered by insurance. Coverage varies by plan, procedure type, and medical indication. Our administrative team can help verify your insurance benefits and discuss payment options before scheduling.
At what age should I start getting screened for colon cancer?
The American Cancer Society recommends colorectal cancer screening beginning at age 45 for people at average risk. Those with a family history of colorectal cancer or other risk factors may need to start screening earlier. Consult with your gastroenterologist to determine the right screening schedule for you.
Can I take my regular medications before a procedure?
Some medications may need to be adjusted or temporarily stopped before certain procedures, particularly blood thinners and diabetes medications. Always provide your doctor with a complete list of your medications and supplements well in advance of your scheduled procedure.
