Our Services
Comprehensive gastroenterology care, expertly delivered.
From routine preventive screening to diagnostic procedures, our board-certified specialists use the latest HD imaging technology and evidence-based protocols to keep you healthy. Below is a full overview of the services we provide.
Colonoscopy
The gold-standard screening for preventing colon cancer.
A colonoscopy is a comprehensive screening procedure that allows us to examine the entire length of the colon using a flexible, high-definition camera. It's the most effective tool we have for detecting and preventing colon cancer — because in addition to identifying issues, we can remove precancerous polyps during the same procedure, often eliminating cancer risk entirely before it develops.
What to expect
Performed at our Fresno facility under twilight sedation, most colonoscopies take 15–30 minutes. You'll rest comfortably during the procedure and recover in our private recovery area. Plan to be at our office for about 90 minutes total, and arrange for a responsible adult to drive you home afterward.
Who it's for
- Adults aged 45+ for routine screening (per current USPSTF guidelines)
- Anyone with a family history of colon cancer or polyps
- Patients experiencing symptoms such as rectal bleeding, persistent abdominal pain, or unexplained changes in bowel habits
- Follow-up after a positive stool-based screening test
Flexible Sigmoidoscopy
A focused examination of the lower colon and rectum.
Flexible sigmoidoscopy is a minimally invasive procedure that examines the sigmoid colon and rectum — the lower portion of the large intestine. It's commonly used to investigate symptoms such as rectal bleeding, lower abdominal pain, or changes in bowel habits, and to screen for colorectal cancer in specific clinical situations.
What to expect
Sigmoidoscopy is typically faster than a full colonoscopy, often does not require sedation, and has quicker recovery time. The procedure usually takes 10–20 minutes, and most patients return to their normal activities the same day.
Who it's for
- Patients with localized lower-bowel symptoms
- Follow-up evaluation after specific findings
- Some screening protocols when full colonoscopy is not appropriate
Stool-Based Screening Tests
Convenient, non-invasive at-home screening options.
Stool-based tests offer an accessible first step in colorectal cancer screening. These tests look for hidden blood or altered DNA in stool — both potential indicators of polyps or cancer that warrant follow-up. They're performed entirely at home and mailed to a lab for analysis.
Available tests
- Fecal Immunochemical Test (FIT) — annual stool test that detects hidden blood
- Stool DNA Test (e.g., Cologuard) — every 1–3 years, detects altered DNA and blood
If a stool-based test returns a positive result, a follow-up colonoscopy is required to investigate further. Talk with our team about which screening approach is best for your individual risk profile.
Upper Endoscopy (EGD)
Diagnostic examination of the upper digestive tract.
An upper endoscopy — formally called esophagogastroduodenoscopy or EGD — uses a thin, flexible camera to examine the esophagus, stomach, and the first part of the small intestine (the duodenum). It's an essential diagnostic tool for evaluating a wide range of upper digestive symptoms.
What to expect
Performed under twilight sedation, an EGD typically takes 10–20 minutes. You'll need to fast for at least 8 hours before the procedure, and arrange a ride home afterward.
Common reasons for an EGD
- Persistent acid reflux or heartburn
- Difficulty swallowing
- Unexplained upper abdominal pain
- Suspected ulcers, bleeding, or H. pylori infection
- Evaluation of Barrett's esophagus
Before Your Procedure
Preparing for your appointment.
Proper preparation is essential to ensure accurate results and a smooth, comfortable experience. Our team will provide detailed, personalized instructions based on your specific procedure.
Colonoscopy Preparation
To ensure a thorough examination of your colon, you'll need to take a prescribed liquid bowel preparation. It is crucial to follow your physician's specific instructions — failure to complete the preparation may result in an inadequate examination, which would mean rescheduling your procedure.
Common preparations include: Nulytely, Colytely, Miralax, Prepopik, and Citrate of Magnesia. Your physician will determine which is best for you.
Review your prep instructions at least two days before your procedure, and call our office if anything is unclear. A successful colonoscopy depends on thorough bowel preparation.
