An upper endoscopy, also called an esophagogastroduodenoscopy or EGD, is a procedure that uses a thin, flexible scope with a light and camera to examine the lining of the esophagus, stomach and the first part of the small intestine. At Dr. Alan R. Plumer, MD in Goshen, New York, we use upper endoscopy to diagnose unexplained abdominal pain, persistent heartburn, bleeding, anemia related to the digestive tract and to take biopsies when needed.
What is upper endoscopy
Upper endoscopy is a diagnostic and sometimes therapeutic procedure. The scope passes through the mouth and down into the upper digestive tract so the physician can see inflammation, ulcers, varices, tumors and other abnormalities. We may take tissue samples, remove small growths or treat bleeding during the same procedure when appropriate.
How the procedure differs from a colonoscopy
Upper endoscopy examines the upper gastrointestinal tract, while colonoscopy examines the colon. Preparation, scope route and common findings differ, though both are performed by gastroenterology teams. For more about colon exams see our colonoscopy service page at Colonoscopy.
Why upper endoscopy matters locally
Symptoms that commonly lead to an upper endoscopy are frequent heartburn, difficulty swallowing, unexplained weight loss, persistent nausea or vomiting, and suspected upper GI bleeding. Early diagnosis in these conditions can prevent progression and guide effective treatment. As a gastroenterology practice in Goshen, we coordinate findings from endoscopy with local primary care and surgical teams when further care is needed.
When we recommend it
- Longstanding or worsening acid reflux or GERD symptoms, to evaluate for esophagitis or Barretts esophagus.
- Difficulty swallowing or odynophagia, to look for strictures, rings or growths.
- Upper abdominal pain or unexplained anemia, to check for ulcers or bleeding.
- Persistent nausea or vomiting, to evaluate for gastric outlet obstruction or severe gastritis.
Key concepts to understand
- Scope and view. The flexible endoscope transmits high resolution images so the mucosal lining can be inspected closely.
- Biopsy vs treatment. A biopsy is a small tissue sample for lab testing. In many cases we can both diagnose and treat during the same procedure.
- Sedation and safety. Most patients receive sedation to reduce discomfort. Monitoring is continuous and recovery typically happens in a short observation period.
- Common findings. Typical diagnoses include reflux esophagitis, peptic ulcers, H Pylori related changes, gastritis, and benign polyps.
- Follow up. Results and any lab pathology guide next steps, which may include medication changes, surveillance, or referral to other specialists.
What to expect before, during and after
Before the procedure
You will get specific fasting instructions and medication guidance from our team. Bring a list of current medicines and any allergy information. If you take blood thinners we will review whether they need to be paused.
Pro tip: A written list of your current medications, including over the counter drugs and supplements, helps us plan sedation and manage bleeding risk.
During the procedure
Under light sedation you lie on your side and the scope is guided through the mouth. The exam usually takes 10 to 20 minutes. If a biopsy or simple therapy is needed it is done through the scope with specialized instruments.
After the procedure
Recovery from sedation takes a short time. You will need someone to accompany you home. Minor throat soreness and bloating are common for a day. We review preliminary findings before you leave and provide written instructions about medications and follow up based on results.
Risks and quality markers
Upper endoscopy is generally low risk, but as with any procedure there are potential complications. These include bleeding after a biopsy or polyp removal, reaction to sedation and, rarely, perforation of the gastrointestinal tract. We follow standard protocols for monitoring and infection control, and pathology review is used to confirm tissue diagnoses.
How we measure quality
- Use of up to date endoscopes and imaging to improve detection.
- Adherence to sedation monitoring standards and recovery observation.
- Timely pathology review and clear follow up plans.
Common questions patients ask
- Is it painful. Most patients are comfortable with sedation and report little to no pain. Mild throat soreness can occur afterward.
- How long does it take to get results. We share the endoscopy findings before discharge. Biopsy results usually take several days and we review them with you once available.
- Will I need more tests. Sometimes. Blood tests, imaging or repeat endoscopy may be recommended depending on findings.

Related services and next steps
Upper endoscopy is one tool in digestive care. Depending on your symptoms we may coordinate testing or care that includes colonoscopy, liver evaluation or specialized consults. See our Gastroenterologist service page to learn about our diagnostic approach, and our Hepatologist services for liver related concerns. If your symptoms are focused on the stomach area read our topic page on Acid Reflux for common causes and treatments. For suspected infections that affect the stomach lining see our page on H Pylori Infection.
How this fits into local care in Goshen
We work with primary care providers and area specialists to make sure endoscopy findings translate into a clear care plan. For information about our locations and how we organize follow up, see our locations page at Locations hub and our practice services overview at Services hub.

Frequently asked questions
How long does an upper endoscopy take and how soon can I go home
The procedure itself usually takes 10 to 20 minutes. Recovery from sedation is typically brief and most patients go home the same day with a companion. We give written aftercare instructions and follow up on pathology when needed.
Will the doctor be able to treat problems found during the exam
Often yes. Small bleeding sources can be treated, small polyps can be removed and any abnormal tissue can be biopsied. More complex treatment may require referral to a specialist.
Are biopsies painful and why are they taken
Biopsies are taken through the scope and cause no additional pain during the procedure. They are taken to let pathology tests determine causes such as infection, inflammation or abnormal cells.
Do I need to stop my blood thinners
We review all medications before the procedure. Some blood thinners may need temporary adjustment to reduce bleeding risk. Do not stop any medication without our guidance or that of the prescribing clinician.
What are the signs of a complication after endoscopy
Seek immediate care if you develop severe abdominal pain, fever, persistent bleeding, shortness of breath or vomiting that does not improve. Minor throat soreness and bloating are common and usually resolve quickly.
Key takeaway
Upper endoscopy is a short, commonly performed procedure that lets a gastroenterologist directly view and often treat diseases of the esophagus, stomach and duodenum. Results guide medical and surgical decisions and help target the right follow up care.
