We have expert solutions for uncomfortable problems

Digestive disorders can be embarrassing and painful. Whether you have gastric reflux, constipation or another digestive system disorder, the specialty team at Phelps’ Thomas E. and Alice M. Hales Endoscopy Unit will provide you with what you need most: comprehensive, compassionate, high-quality care from people you can talk to. We are devoted to your comfort and ensuring your optimal health.

Our specially-trained gastroenterologists, anesthesiologists, nurses and technicians use cutting-edge technology and the largest range of procedures in the Hudson Valley to diagnose and treat all diseases of the digestive system, including the esophagus, stomach and intestines, as well as related organs like the liver, gallbladder and pancreas.

The Endoscopy Unit at Phelps features 9 private rooms, which are fully equipped for patient comfort.


This simple procedure takes only a few minutes and allows your doctor to view abnormalities in your upper digestive tract through a tube that has an attached light and camera.

Endoscopic Ultrasound (EUS)

Your doctor may use ultrasound to obtain more detailed images of your digestive tract and surrounding organs, as well as tissue samples. EUS can detect small lesions and stones in the gallbladder and bile duct. It can also determine stages of esophageal or rectal cancer before surgery or chemotherapy.

Endoscopic Retrograde Cholangiopancreatography (ERCP)

This procedure uses a special X-ray, called fluoroscopy, to ensure that the ring-like muscle at the bottom of the pancreatic and bile ducts known as the sphincter is functioning properly.

Radio Frequency Ablation (RFA)

RFA painlessly burns away abnormal cells. It is a common treatment for Barrett’s Esophagus, which occurs when cells lining the esophagus go through changes that can sometimes lead to esophageal cancer. About 10% of people suffering from chronic reflux disease develop Barrett’s Esophagus.

Balloon Enteroscopy

Balloon enteroscopy allows your doctor to visually examine the hard-to-reach small intestine and diagnose bleeding, familial polyp syndromes, or the causes of abnormal abdominal X-rays.


With this common procedure, your doctor can spot and remove precancerous polyps in your colon or rectum, as well as detect and diagnose colorectal cancer. Colorectal cancer is the third most common cancer and the third leading cause of cancer death in the U.S. It is important to begin regular screenings for this disease at age 50.

Phelps keeps everything moving along

The digestive system is a muscular conveyer belt that moves food through your body, from beginning to end, breaking it down along the way so you can absorb necessary nutrients. A number of disorders can interrupt this natural movement. The highly trained gastroenterologists at the Phelps Gastrointestinal Motility Center specialize in these disorders and can help you get things moving again.

Tips for optimal digestive health: Healthy Digestive System, Eat enough fiber, Cut down on fat, Consume lean meats, Take probiotics, Eat at regular intervals, Drink lots of water, Limit smoking and alcohol, Exercise, Reduce stress

A poor diet can interrupt good digestion. Our registered dietitians are here to help you design a personalized nutrition plan that works for you. To make an appointment, please refer to our Nutritional Counseling page.

Gastrointestinal disorders can be awkward. At Phelps, we ensure the highest level of professionalism, confidence and comfort.


More than four million people in the U.S. experience frequent constipation. A lack of fiber, fluids, or exercise can cause constipation, although other conditions such as Parkinson’s disease, diabetes, or hypothyroidism may play a role.


Trouble swallowing can result from many problems, from a blockage in the esophagus to muscle dysfunction in the mouth, tongue or esophagus. We use esophageal manometry to test and assess the function and strength of these muscles.

Esophagitis and GERD

Excessive burping and chest pain can be signs of gastroesophageal reflux disease (GERD), which returns digested food from the stomach to the esophagus. The most common form of GERD is acid reflux. We use endoscopy, esophageal manometry, and sometimes an esophageal pH study to investigate symptoms.

Fecal incontinence

Although this may be hard to discuss–even with your doctor–you may feel relieved to know that some form of this condition affects 2-15% of people in the U.S. It has many causes, including liquid stool, increased or decreased rectal sensitivity, or decreased strength in the anal sphincter. We perform a thorough evaluation that includes a medical history, anal and rectal examinations, and often an ano-rectal manometry to assess muscle function and sensation.

Functional dyspepsia

This pain in the center of the abdomen is often related to delayed gastric emptying.


Gastroparesis, also known as delayed gastric emptying, can produce nausea, vomiting, bloating, abdominal pain, or feeling full too soon while eating. We use endoscopy and sometimes an abdominal CT scan to evaluate this condition, and to rule out ulcers, tumors, or severe gastritis. We also may conduct a gastric emptying study to measure the emptying process. During this procedure, we monitor foods that you eat as they travel through your digestive system.

At the Motility Center, we use a variety of procedures to diagnose and treat many symptoms and disorders, including:

  • Abdominal pain
  • Bloating
  • Chronic cough
  • Diarrhea
  • Gassiness
  • Hoarseness and vocal cord changes
  • Intestinal pseudo-obstruction
  • Nausea and vomiting
  • Persistent heartburn
  • Pre-surgical evaluation
  • Regurgitation

In cases of fecal incontinence and constipation, we use anorectal biofeedback and pelvic floor muscle retraining to help you learn to better control the function of essential muscles and to improve your sensory response.
