How your gastroenterologists in Las Vegas, Nevada can help protect your health.

A gastroenterologist is an expert at diagnosing and treating digestive system issues, including problems with your stomach, intestines, colon, gallbladder, liver, pancreas, and esophagus. Using state-of-the-art diagnosing tools including cutting-edge imaging, your gastroenterologist can detect and treat medical conditions and safeguard your health.

The gastroenterologists at Comprehensive Digestive Institute of Nevada in Las Vegas, NV offer a wide range of gastrointestinal services to help you stay healthy.

So, when should you see your gastroenterologist? These are just a few of the signs and symptoms that may indicate you need at least a consult with your gastroenterologist. You should contact your GI specialist if you experience:

  • Chronic abdominal pain
  • Sudden onset diarrhea or constipation
  • Unexplained weight gain or weight loss
  • Chronic indigestion, heartburn, nausea, or vomiting
  • Frequent bloating or gas
  • Rectal bleeding

These signs and symptoms could be an indication of:

  • Irritable bowel syndrome, commonly known as IBS
  • Gastroesophageal reflux disease, commonly known as GERD
  • Inflammatory bowel disease, commonly known as IBD
  • Gallstones or ulcerative colitis
  • Liver disease or pancreatitis
  • Colorectal or stomach cancer

When you see your gastroenterologist, make sure to bring your medical information with you, including a full list of your medications. Your GI specialist will do a comprehensive examination of your abdomen and stomach, and record your symptoms and vital signs. You may need additional testing which can include:

  • Blood work and lab testing
  • Diagnostic imaging and x-rays
  • Motility testing

Your gastroenterologist may also recommend adding endoscopic procedures like an upper endoscopy and colonoscopy. Even without symptoms, you should plan on having a colonoscopy by the time you are 45 years old, as a preventive measure against developing colorectal cancer. This type of cancer is the third leading cause of cancer deaths in this country.

If you are suffering from abdominal or stomach pain, don’t delay seeing your gastroenterologist. Abdominal and stomach issues can be serious. Early detection and treatment are critical to protecting your health. To find out more about how a gastroenterologist can help you, call the gastroenterologists at Comprehensive Digestive Institute of Nevada in Las Vegas and Henderson, NV at (702) 483-4483.

Tags: Colonoscopy  

Are you approaching age 50? Has your primary care physician referred you for a colonoscopy? If so, contact the gastroenterologists at Comprehensive Digestive Institute of Nevada in both Las Vegas and Henderson, NV. Here, your team of gastroenterologists performs high-resolution colon examinations that are both comfortable and able to yield accurate results.

Why should you get a colonoscopy?

A colonoscopy yields clear images and real-time videos of the interior of the colon/large intestine. This simple screening test tells your doctor if you have, or at risk for, colon cancer, the second leading cause of cancer deaths in the United States, according to the American Society of Clinical Oncology (ASCO).

Because colon-rectal cancer risk increases with age, colonoscopy screenings beginning at 50 are important, even life-saving. These tests reveal the presence of colon polyps, small benign growths that may become cancerous over time. In fact, all colon malignancies arise from polyps. This is why your gastroenterologists in Las Vegas and Henderson, NV, want to see, remove, and biopsy them.

The procedure

The day before your test, your doctors here at Comprehensive Digestive Institute of Nevada will ask you to complete a colon cleansing with fasting, laxatives, and clear liquids. When you arrive the next day, you will be given medication to relax your body, and depending on your particular protocol, light sedation or anesthesia, as well.

Next, the doctor uses a thin, lighted endoscope to view the entire length of your large intestine, starting with the anus and rectum. He'll take pictures throughout and tissue samples as needed. This examination takes about 30 minutes, and most patients feel drowsy or even sleep all the way through.

In the recovery room, your physician will review the results with you, and afterward, a friend or relative will drive you home to rest for the rest of the day.

Other uses for colonoscopy

Besides screening for cancer and polyps, a colonoscopy can reveal the causes of diarrhea, abdominal pain, and rectal bleeding. Conditions uncovered include:

  • Diverticulosis
  • Irritable Bowel Disease
  • Intestinal obstructions

Know your colon health

Colonoscopy can help you know all about it, and when it comes to colon cancer, this easy test could save your life. For more information about this and our other state of the art GI procedures, contact Comprehensive Digestive Institute of Nevada. We are open Monday through Friday 8 am to 5 pm. Phone either one of our offices in Las Vegas or Henderson, NV, today by dialing (702) 483-4483.

Seeing your gastroenterologist every ten years for screenings could save your life.

Colorectal cancer is one of the leading causes of cancer-related death in both men and women in the US. While this form of cancer is highly curable when detected early on, the problem remains that most people don’t get routine colon cancer screenings. Colon cancer screenings are one of the most valuable and effective tools that our Las Vegas gastroenterologists have to be able to catch colorectal cancer early on. In fact, 60 percent of colorectal cancer deaths could be prevented with a simple screening.

Here’s what you should know about colon cancer screenings:

You should get your first colonoscopy at 50 years old

Since colon cancer is most often diagnosed between the ages of 50 to 75, these are the ages in which you should get routine colon cancer screenings. Your first colonoscopy should happen by your 50th birthday, and this goes for both men and women. If your test results come back normal, then you may not need another colonoscopy for 10 years.

You may need to get them sooner if you have risk factors

There are certain risk factors that can increase your chances of developing colorectal cancer. The biggest risk factors include:

  • A family history of colorectal cancer
  • A personal history of colorectal cancer or colon polyps
  • Having an inflammatory bowel disease (IBD) such as ulcerative colitis or Crohn’s disease

Other risk factors include:

  • Sedentary lifestyle
  • Diabetes
  • Smoking
  • Heavy drinking
  • A high-fat diet
  • Older age

By making simple lifestyle modifications, you can reduce your risk of colon cancer. Talk with your gastroenterologist today for help on implementing these changes.

Colonoscopies can also diagnose common gastrointestinal problems, too

Along with finding/removing colon polyps and diagnosing colorectal cancer during its early stages, a colonoscopy may also be prescribed by one of our Las Vegas intestinal doctors if you are dealing with certain symptoms such as abdominal pain, blood in the stool, unexpected weight loss, or rectal pain. Since a colonoscopy gives us the chance to examine the lining of the lower intestines, it also allows us to find ulcers, inflammation, bleeds, and tumors.

Interested? Give us a call

If you’ve just turned 50 years old, give yourself the gift of good health and schedule your colon cancer screening at our Las Vegas gastroenterology practice. Call Comprehensive Digestive Institute of Nevada today by dialing (702) 483-4483.

Tags: Celiac Disease  

Find out the symptoms of celiac disease and how to manage your symptoms.

By now, many people have heard of celiac disease; however, not many people understand what it is. While this condition affects the digestive tract it’s actually an autoimmune disorder. When a person consumes gluten not only does the body begin attacking the intestines but it also affects how the body absorbs nutrients. Find out more about the warning signs of this disorder, when to see a doctor, and how our Las Vegas, NV, gastroenterologists help patients manage their symptoms.

Signs and Symptoms of Celiac Disease

Here are the classic symptoms of celiac disease:

  • Diarrhea or constipation (or both)
  • Bloating
  • Gas
  • Unexplained fatigue
  • Weight loss
  • Iron-deficiency anemia
  • Itchy rash

If you are dealing with these symptoms, particularly after eating wheat products, then you should visit your Las Vegas gastrointestinal doctor to find out if you could have celiac disease. It’s important to distinguish between celiac disease and gluten sensitivity.

Those with gluten sensitivity may experience similar symptoms to celiac disease but they often aren’t as intense and it doesn’t cause the immune system to attack the intestinal tract like true celiac disease. Untreated celiac disease can also lead to a host of other complications including osteoporosis, other immune disorders and even cancer, so it’s important to see treatment right away if you suspect that you have celiac disease.

How is celiac disease treated?

While there is no cure for this autoimmune disorder the most effective gastroenterology treatment option is to maintain a strict gluten-free diet. Even those with non-celiac gluten sensitivity should also follow the same diet. This diet will allow the gut to heal, which will eliminate your symptoms and prevent future complications.

Your doctor may also recommend certain vitamins and supplements. After all, many people with celiac disease may also experience a deficiency in iron, calcium, zinc, magnesium, B12, and vitamin D. It’s also possible to develop a vitamin B deficiency if your gluten-free diet isn’t providing you with sufficient vitamin B supplementation. In this case, your gastroenterologist may prescribe a dietary supplement that you should take every day.

If you are dealing with the symptoms of celiac disease in Las Vegas it’s important that you see your doctor as soon as possible for a diagnosis. Call Comprehensive Digestive Institute of Nevada today to schedule an appointment or ask any questions about gastroenterology.

Tags: Endoscopies  

An endoscopy is a diagnostic imaging test that allows the physician to examine and take pictures of the inside of an organ or specific area of the body. Your Las Vegas, NV, gastroenterologist may recommend an endoscopy if you are experiencing pain or symptoms like chronic or severe acid reflux. The Comprehensive Digestive Institute of Nevada offers endoscopies and other imaging tests of the upper and lower digestive tract.

Endoscopy in Las Vegas, NV

Q: How does an endoscopy work?

A: An endoscopy is performed by inserting a small tube with a light and camera attached at the end (endoscope) into the upper or lower digestive tract to look for growths, lesions, or other problems that may be causing symptoms. You will receive a detailed list of instructions prior to the procedure in order to prepare, including dietary restrictions and information about medication.

Q: When is an endoscopy necessary?

A: Endoscopies are primarily used as a diagnostic tool. Your Las Vegas, NV, doctor will order one if you are experiencing symptoms of certain digestive issues like GERD, colitis, or blockages.

Q: Will I be awake during the procedure?

A: Sedation is provided to keep you comfortable and relaxed during the procedure, but you will remain awake.

Q: Will I have to take time off for the procedure?

A: Endoscopies are typically performed on an outpatient basis at Comprehensive Digestive Institute of Nevada, but you will need someone to help you get home after the procedure until the sedation fully wears off. If your procedure is in the morning or during the work day, you should make arrangements to take the rest of the afternoon off.

Q: Is it painful?

A: You may experience some discomfort in the throat after the endoscope is removed, but sedation is provided to ensure that you will remain as comfortable as possible.

Q: How long is the recovery period?

A: After the procedure (10-15 minutes), you will recover at the doctor's office for approximately 30 minutes. Patients can typically eat again immediately after.

This diagnostic procedure could shed some light on your gastrointestinal issues.

When you’re dealing with stomach pain, nausea and other symptoms wouldn’t it be lovely if your body could just tell you what’s going on? Unfortunately, this isn’t how life works but we can find out what’s going on within your gastrointestinal tract thanks to a helpful procedure known as an endoscopy. Our Las Vegas and Henderson, NV, gastroenterologists are here to explain when an endoscopy may be necessary for you.

What is an endoscopy?

An upper or lower endoscopy is a diagnostic procedure that is performed by our GI specialists to be able to get a more detailed visual of what is going on within the digestive tract. This minimally invasive, outpatient procedure is painless and performed right here in our office.

When is an endoscopy performed?

There are many cases in which an endoscopy can provide us with the insight we need to be able to figure out what’s going on with your digestive tract. An endoscopy can be used to:

  • Pinpoint the cause of digestion-related symptoms (e.g. bleeding; abdominal pain)
  • Determine the severity of your digestive problem
  • Monitor preexisting gastrointestinal conditions
  • To biopsy a specific area of the digestive tract
  • To screen for cancer
  • To remove polyps, treat an obstruction or to stop bleeding

An endoscopy is able to view the esophagus, stomach, and upper and lower intestines, and it provides a more accurate view of your digestive health than X-rays. It’s also better at discovering ulcers, inflammation or tumors.

What should I expect from this diagnostic procedure?

Before the endoscopy is performed an IV will be administered to provide you with sedation and pain relief. You will not receive general anesthesia because it’s a quick and minimally invasive procedure, but many people feel so relaxed during conscious sedation that they even fall asleep during their endoscopy.

Once the sedation has taken effect, we will gently insert a thin flexible tube (the endoscope) into the throat and slowly guide it through the esophagus and into the stomach and digestive tract. An upper endoscopy usually takes anywhere from 10 to 15 minutes; however, it could take longer if an area has to be biopsied or polyps have to be removed.

If you are living in Las Vegas and Henderson, NV, and dealing with gastrointestinal issues then it’s a good time to schedule a consultation with one of our gastroenterologists who can help you get to the bottom of your health issues. Call Comprehensive Digestive Institute of Nevada today.

Tags: Colonoscopy  

A colonoscopy procedure is an important and effective diagnostic and treatment tool that has many benefits and understanding it better can help you determine that it is the best option for you. Learn more about colonoscopy and why your doctor may recommend it with Comprehensive Digestive Institute of Nevada in Las Vegas and Henderson, NV.

What is a colonoscopy? 
Colonoscopy is a procedure which can serve as a screening for colon cancer, be used to investigate symptoms, or even take biopsies or remove issues like polyps. The procedure itself uses a long, thin, hollow tube with a camera attached to the end. The tube, called a colonoscope, is flexible and about the width of a finger. The camera allows your doctor to visually inspect your lower digestive tract and insert specialized instruments to perform treatments.

Why is colonoscopy recommended? 
Your doctor may recommend colonoscopy if you are over the age of 50 as part of a preventative care routine. After 50, those with an average risk of colon cancer should have a colonoscopy once every 10 years. However, your doctor may also suggest colonoscopy in the case of:

  • bloody stool
  • polyps
  • bleeding from the rectum
  • unexplained changes in bowel habits
  • unexplained abdominal pain
  • pus or mucus in the stool

If you think you could benefit from a colonoscopy, you should consult with your gastroenterologist to ensure that this is the best treatment for you.

Colonoscopy Treatments in Las Vegas and Henderson, NV
If your doctor recommends a colonoscopy, you will need to prepare by performing several steps prior to your treatment. Your doctor will prescribe a regimen of laxatives or enemas to cleanse your bowel and help prepare your body for your treatment. You will also need to fast for 24 hours before your colonoscopy.

For more information on colonoscopy, please contact your gastroenterologist at Comprehensive Digestive Institute of Nevada in Las Vegas and Henderson, NV. Call (702) 483-4483 to schedule your appointment in Las Vegas or (702) 483-4483 to schedule your appointment in Henderson today!

Find out if the digestive issues you’ve been having could be due to celiac disease.

Gluten is a word we hear a lot when it comes to nutrition and diet. We see gluten-free bakeries and restaurants cropping up all over and becoming pretty mainstream. While gluten isn’t a problem for a lot of people, this protein found in foods such as breads, pastas and cereals could cause serious intestinal damage in someone with celiac disease. So what is celiac disease and how can you tell whether you have it? Our Henderson, NV, gastroenterologists are here to shed some light on this rather popular subject.

What is celiac disease?

Celiac disease is an autoimmune disorder that negatively impacts the digestive system when consuming foods that contain gluten. Gluten is found in barley, wheat and rye products such as many cereals, pastas and breads. Over time, consuming gluten can lead to damage to the lining of the intestines; fortunately, most symptoms and complications can be reversed once you begin a gluten-free diet.

What are the symptoms of celiac disease?

Celiac disease can manifest itself in a myriad of ways and symptoms can differ greatly from person to person. In fact, according to the Celiac Disease Foundation, there are over 200 symptoms that may occur as a result of celiac disease. Common symptoms include:

  • Bloating
  • Abdominal pain
  • Gas
  • Constipation
  • Chronic diarrhea
  • Fatigue
  • Poor concentration and memory
  • Reduced appetite
  • Rash
  • Unexpected weight loss
  • Depression, mood swings and irritability

If you or a family member is dealing with any of these symptoms it’s important that you turn to our Henderson, NV, gastrointestinal specialists to figure out what’s going on. Since these symptoms can also be indicative of other issues, it’s important that you get a proper diagnosis and so that we then determine the best treatment plan for you.

How is celiac disease treated?

The best and most effective treatment for celiac disease is to switch to a strictly gluten-free diet. This means nixing gluten from your diet completely. Since we know making the transition can be challenging, particularly for children and teens, we can work with you to create a dietary plan that will help you find suitable and safe alternatives for foods that contain gluten.

Comprehensive Digestive Institute of Nevada offers two convenient locations in Henderson, NV, and Las Vegas. If you are concerned that you or your child may have celiac disease then it’s important to seek a professional evaluation as soon as possible.

What your gastroenterologists in Las Vegas want you to know about GERD

You’ve probably heard more than a few people complain about heartburn, because heartburn is a common problem. The truth is continual heartburn could be a sign of something more serious. It could be a sign of gastroesophageal reflux disease, also known as GERD. So what is gastroesophageal reflux disease? Your gastroenterologists at Comprehensive Digestive Institute of Nevada in Las Vegas, NV want to help answer that question.

GERD is a condition caused by the sphincter muscle between your stomach and esophagus not working correctly. Normally, this sphincter muscle closes, keeping stomach acid from traveling up your esophagus. In cases of gastroesophageal reflux disease, the sphincter muscle only partially closes, allowing stomach acid to invade your esophagus.

There are some easily identifiable signs and symptoms of GERD, including:

  • Frequent pain in your throat
  • A frequent sour taste in your mouth
  • Frequent bad breath
  • Chronic wheezing and coughing
  • Tooth sensitivity from eroding tooth enamel
  • Chest pain, nausea and vomiting

There are many changes you can make that will reduce the signs and symptoms of GERD. You can try to:

  • Eat smaller meals
  • Avoid smoking and other tobacco products
  • Avoid eating before lying down or bedtime
  • Reduce or eliminate acidic or spicy foods
  • Take over-the-counter antacids

If you think you have gastroesophageal reflux disease, it’s best to seek out the help of your gastroenterologist because GERD can progress, causing extensive damage to your esophagus. For example, GERD can cause:

  • Esophageal inflammation, resulting in swelling of your esophagus and problems swallowing
  • Esophageal ulcers, resulting in problems swallowing, nausea and pain in your chest
  • Esophageal narrowing and scarring, leading to problems swallowing

Don’t ignore the signs and symptoms of GERD, especially when gastroesophageal reflux disease can be effectively treated by your gastroenterologists at Comprehensive Digestive Institute of Nevada. Don’t wait for GERD to get worse. Instead, call your gastroenterologists at Comprehensive Digestive Institute of Nevada in Las Vegas, NV today!

Tags: Upper Endoscopy  

An upper endoscopy is a simple, yet state-of-the-art gastrointestinal procedure. Why would you need this test? The reasons are many, making endoscopy one of the most versatile and reliable diagnostic tools your gastroenterology doctor in Henderson delivers. According to the Centers for Disease Control in Atlanta, almost 7 million American adults undergo an endoscopy annually, helping doctors uncover GI disease and to treat it properly. At Comprehensive Digestive Institute of Nevada, count on expert, compassionate care from our team of board-certified gastroenterologists during upper endoscopy or other GI procedures you may need.

What happens during an upper endoscopy?

During an upper endoscopy, you will be lightly sedated and lie on one side. Your physician will anesthetize the back of your throat and introduce a thin, lighted tube which has a miniature video camera. As the tube travels down your esophagus to your stomach and duodenum (upper intestine), your doctor views real-time color images on a monitor. He is able to see areas of bleeding, growths, malformations, hernias and other irregularities.

In addition, your Henderson gastroenterologist may take small tissue samples for biopsy (analysis for cancer and Heliobacter pylori), perform tissue ablation to destroy areas of irregularity (such as Barrett's Esophagus) or bleeding or to stretch strictures that narrow the GI tract.

The entire procedure takes about 30 minutes, and the vast majority of patients tolerate it very well. Because of the sedation, a responsible adult must drive you home afterward. At home, you can eat and resume light activity right away, but you may feel a bit bloated because of the air introduced by the endoscope during the procedure.

Why would you need an upper endoscopy?

When patients present with symptoms of unexplained pain, digestive issues, nausea, vomiting or bleeding, the GI doctor may order an upper endoscopy. While X-rays render a good visualization of structures in the GI tract, irregularities such as polyps, bleeding and inflammation are detected better with endoscopy, says the American Society for Gastrointestinal Endoscopy. Plus, the test is a minimally invasive, comfortable way to take biopsies for cellular analysis.

Rest assured

At Comprehensive Digestive Institute of Nevada, our professional staff knows the literal ins and outs of upper endoscopy. Your procedure will be safe, accurate and comfortable. If your primary care physician wants you to have an upper endoscopy, contact our office staff at (702) 483-4483. We have locations in both Henderson and Las Vegas, NV.

When diarrhea shows up, it’s often during the worst of times: while in the middle of a meeting, at the gym or on a date. Diarrhea certainly won’t wait for the most opportune time. So if you find yourself spending more time than usual in the bathroom you may be wondering what’s going on. Here are some common causes of diarrhea and when you should visit one of our Henderson and Las Vegas gastroenterologists for a proper diagnosis.

  • Medications (e.g. blood pressure medication)
  • Stress

  • Colon polyps
  • Irritable bowel syndrome (IBS)
  • Inflammatory bowel disease (IBD)
  • Diabetes
  • Pancreatitis
  • Diverticulitis
  • Hyperthyroidism (an overactive thyroid)

There are so many different issues, from minor and self-limiting to chronic conditions, that could be causing your symptoms. There are some measures you can take to help ease your symptoms such as:

  • Stay hydrated (drinking water is particularly important when you have diarrhea)
  • Stay away from foods that are acidic and spicy (stick to foods that are a bit blander for the time being and slowly reincorporate other foods back into your diet)
  • Make sure to always wash your hands

In most cases, diarrhea will clear up on its own. Of course, you may also be wondering when you should turn to one of our Henderson and Las Vegas GI doctors for a proper diagnosis and treatment. If you haven’t noticed relief from your diarrhea within two day, it’s best to give us a call. We can determine whether you should come into our office for care. You should also give us a call immediately if:

  • You have a fever that’s over 101.3 degrees F
  • You have black stools
  • There is blood in the stool
  • You are experiencing signs of dehydration
  • You also have sudden or several abdominal pain

Common Stomach Problems and How We Can Help

Digestive problems can happen to anyone and gastroenterologists are medical professionals who specialize in diagnosing and treating stomach issues. Dr. Gary Chen is one of the specialists in gastroenterology at the Comprehensive Digestive Institute of Nevada, in Las Vegas, NV. Here are some of the common gastric problems he can help you with.


The most common causes of constipation include insufficient fiber in your diet, not drinking enough water, resisting the urge to go to the bathroom, not getting enough exercise, and taking certain medications. To avoid constipation and the discomfort it causes, the first thing to do is change your diet by gradually adding more fiber. You should also increase the amount of fruit and vegetables in your diet, and bulk up on beans. Additionally, it helps to drink around eight 8-ounce glasses of water each day.

Gas and Bloating

Intestinal gas and abdominal bloating affect just about everyone at some time or other. Both are normal conditions that occur as your body converts food into energy. If, however, you are experiencing them often and they are making you feel uncomfortable or embarrassed, you can make a few lifestyle changes to help reduce their effects. These changes include eating more slowly to avoid swallowing as much air, exercising regularly, avoiding carbonated beverages, avoiding chewing gum, quitting smoking, and checking your dentures.

Acid Reflux

Acid reflux, also known as gastroesophageal reflux, occurs when acid from the stomach flows backward into the esophagus – the tube connecting the stomach and throat. When this happens, you may feel a burning sensation in your chest and throat. You may also notice a taste of regurgitated food. In some cases, acid reflux may develop into a more severe condition known as gastroesophageal reflux disease (GERD). If you suffer from occasional bouts of acid reflux, you can make some lifestyle changes to alleviate the condition. These include maintaining a healthy weight, avoiding trigger foods, and eating low-fat, high-protein meals.


Gastroenteritis, also known as stomach flu, is caused by a viral infection and is the second most common illness in the U.S. It is spread through contaminated food and water and passed on by contact with someone who is infected. The best way to avoid gastroenteritis is by washing your hands frequently. The most common symptoms of this condition are vomiting and diarrhea, so it’s important to drink plenty of water. After you recover from gastroenteritis, taking a probiotic supplement can help to rebalance the beneficial microbacteria throughout your GI tract and also to strengthen your immune system.

If you need a gastroenterologist in Las Vegas, call Dr. Chen at 702-483-4483.

Endoscopic ultrasound, or EUS, is a modern imaging technique that visualizes organs such as the pancreas, gall bladder, liver and more. Used by your team at Comprehensive Digestive Institute of Nevada in Las Vegas and Henderson, this reliable day surgery helps diagnose and treat several GI disorders. Here are the details you need to know.

What is an endoscopic ultrasound?

Performed at our state of the art endoscopic center in Las Vegas, endoscopic ultrasound allows your gastroenterologist to see your digestive tract and organs such as the pancreas and gall bladder. Additionally, the doctor obtains images of hard-to-see structures such as lymph nodes and blood vessels.

When is this procedure used?

EUS helps doctors further explore lumps and other abnormalities previously viewed with other diagnostic procedures. It also allows for fine-needle aspiration, a method of obtaining tissue samples for biopsy and other kinds of analysis. Endoscopic ultrasound helps stage cancer of the GI tract and lungs as well.

Procedure details

Inform your doctor at Comprehensive Digestive Institute of Nevada of your routine medications, including blood thinners such as aspirin or coumadin, and if you are allergic to shellfish or iodine.

Preparation involves pre-procedure fasting. The day of the procedure, you'll be given IV sedation. The doctor then uses a thin, flexible tube inserted in the mouth and down the throat to advance a camera and ultrasound instrument.

During the 30 to 90 minute procedure, your GI doctor views real-time photos on a television monitor and views sound wave images on a separate television set. Afterward, you'll rest in the recovery room, discuss results with your doctor, and go home with a responsible adult friend or relative. You may return to your usual routine the next day because EUS is usually well-tolerated by the majority of patients.

Contact us for additional information

At Comprehensive Digestive Institute of Nevada, our nine board-certified gastroenterologists are experts in their field and ready to help you. We have two convenient offices: one in Henderson and the other in Las Vegas. Call us to know more about our endoscopy center and on EUS. Phone us weekdays at (702) 483-4483.
