What is a Flexible Sigmoidoscopy?
A flexible sigmoidoscopy is a critical diagnostic tool to evaluate the health of your large intestine, or colon. An ultra-thin, flexible tube called a sigmoidoscope is inserted in the rectum and guided up through the intestine.
The tube contains a tiny camera at the end which provides the doctor with a view of your sigmoid colon, which is the last two feet of the large intestine. The sigmoidoscope also allows the doctor to take samples of tissue for later biopsy. Tissue biopsy is the definitive way to determine whether there are precancerous or cancerous changes in your tissue cells.
The sigmoidoscopy procedure is often combined with a colonoscopy because the sigmoidoscope doesn’t show the entire colon, only the lower portion. Sigmoidoscopy may be recommended over colonoscopy because it often doesn’t require anesthesia and is a faster procedure than colonoscopy.
A flexible sigmoidoscopy can be used to determine the cause of intestinal problems like abdominal pain and bowel issues like diarrhea and constipation. It is also used to look for abnormal growths or polyps. It is also a vital tool to screen for colon and rectal cancer.
Flexible sigmoidoscopy may be recommended if you are over 50 years old to help detect colon and rectal cancer in the early stages, when it is the most treatable. Colorectal cancer is the third leading cause of cancer-related deaths in the United States, according to the American Cancer Society. Each year, about 150,000 new cases are diagnosed in this country, and 50,000 people will die of the disease.
The flexible sigmoidoscopy procedure is a safe, effective way to determine the health of your sigmoid colon. It is a vital tool in maintaining your good health. If you are having abdominal issues, or you are at least 50 years old, a flexible sigmoidoscopy can help you. Your doctor can tell you more about flexible sigmoidoscopy and other procedures to help you feel better.
Chances are good you’ve heard of a colonoscopy before, whether through a health report on the news or because you know someone who had to get one. A colonoscopy is a diagnostic procedure and often a screening tool that allows your gastroenterologist to be able to see what the lining of the colon and intestines looks. A thin scope is inserted into the rectum and carefully directed through the lower intestines. The scope has a camera at the end that allows your doctor to pinpoint potential problems with the lining of the intestines or colon. There are a few reasons why your doctor might recommend getting a colonoscopy.
If a patient comes in complaining of abdominal pain, rectal bleeding, or persistent diarrhea and these symptoms can’t be explained through a routine exam and testing then your GI doctor may recommend performing a colonoscopy to be able to determine the root cause for these symptoms. This might be particularly helpful if you or a family member has a history of colon cancer or colon polyps.
Even if you are feeling fine, both men and women, once they reach 50-years-old, will need to start getting routine colonoscopies to screen for colon polyps and other signs of colorectal cancer. A colonoscopy is one of the most effective screening tools a gastroenterologist has for being able to pinpoint warning signs of cancer with the large intestines and colon. No other screening tool will be able to provide the detailed imaging that a colonoscopy can.
If the results of your routine colonoscopy come back normal then you probably won’t need to repeat the procedure for another 10 years. If one or more polyps were detected during your colonoscopy your GI specialist may choose to remove them during the procedure but may recommend that you come in more regularly for a colonoscopy.
You may also need to have this procedure performed more often if you have a family or personal history of colon cancer or colon polyps. It’s important to be upfront about your detailed medical history when talking to a gastrointestinal specialist to determine the best colonoscopy schedule to protect your digestive health.
No matter if you are experiencing distressing intestinal symptoms or you just turned 50-years-old, it’s a good idea to turn to a gastrointestinal specialist who can provide you with the individualized care you need. Remember, getting a colonoscopy after you turn 50 could just end up saving your life!
Cancerous carcinoid tumors form in the lining of your gastrointestinal tract and can be caused by certain digestive conditions. The rare tumors are often treated with surgery and medications.
What are carcinoid tumors?
Carcinoid tumors develop when a mutation occurs in the neuroendocrine cells in your digestive system. The dual-purpose cells have both nerve and endocrine features and are capable of producing hormones. Over time, the cancerous cells gradually take over healthy cells and form a tumor. Carcinoid tumors tend to form in the colon, stomach, small intestine or rectum.
Who gets carcinoid tumors?
If anyone in your family has had multiple endocrine neoplasia type 1 syndrome (MEN1) or neurofibromatosis type 1 syndrome (NF1), you may be at greater risk of developing a carcinoid tumor. Your risk also rises if you have Zollinger-Ellison syndrome, pernicious anemia or atrophic gastritis. Older people and women are more likely to develop carcinoid tumors.
What are the symptoms of carcinoid tumors?
There are often no symptoms when a carcinoid tumor is small. In fact, you may only learn that you have a tumor after undergoing a routine colonoscopy or another diagnostic test. Symptoms may occur if the tumor secretes hormones or grows larger. Symptoms depend on the location of the tumor, but may include:
- Pain in the abdomen
- Unexplained weight loss
- Rectal pain
- Stool color changes or blood in the stool
- Abdominal pain
How are carcinoid tumors treated?
Surgery is used to remove all or as much of the tumor as possible. Medications may also be helpful. Depending on your condition, your gastroenterologist may recommend interferon injections that enhance the immune system's ability to attack the tumor or medications that prevent the tumor from releasing hormones.
If your carcinoid tumor has spread to your liver, your gastroenterologist can offer several other treatment options, including cryoablation (freezing) or radiofrequency (heat) treatments to kill the cancer cells. Removing part of the liver during a surgical procedure may be helpful, as can closing off the hepatic artery that feeds the tumor.
Although most gastrointestinal symptoms aren't caused by cancer, it's important to see your gastroenterologist if you experience frequent heartburn, nausea, vomiting, diarrhea, constipation, bloating or other symptoms.
Ulcerative colitis, a type of inflammatory bowel disease, causes painful open sores in your large intestine and rectum. The disease can affect both children and adults. Although there is currently no cure for ulcerative colitis, symptoms can be managed with medications and dietary changes in many cases.
What are the symptoms of ulcerative colitis?
Although symptoms of ulcerative colitis vary depending on the severity of the disease, diarrhea that contains blood or pus is a frequent problem. It may be difficult to get the bathroom in time, particularly if a bout of diarrhea strikes in the middle of the night. Other symptoms can include:
- Abdominal cramping and pain
- Joint pain
- Weight loss
- Canker sores
- Rectal pain
- Difficulty defecating
If you have severe ulcerative colitis, you may be more likely to develop one or more serious complications, such as severe dehydration or bleeding, a perforated colon, osteoporosis, megacolon, blood clots or colon cancer.
What are the risk factors for ulcerative colitis?
Ulcerative colitis symptoms usually appear between the ages of 15 and 35. You're more likely to develop ulcerative colitis if other people in your family have it. Your ancestry may also affect your risk. Caucasians and people of Ashkenazi Jewish descent get the disease more often than other ethnic groups.
How is ulcerative colitis treated?
Medications that relieve inflammation and suppress your immune system can be helpful if you have ulcerative colitis. Corticosteroids may also reduce inflammation and bring about a remission of symptoms. Because prolonged use of corticosteroids can cause high blood pressure, diabetes and osteoporosis, they're only recommended for short-term use. Anti-diarrheal medications can reduce the frequency of diarrhea, while iron supplements may prevent anemia caused by bleeding.
Approximately 25 to 40 percent of people who have ulcerative colitis will eventually need surgery to remove the colon, according to the Crohn's and Colitis Foundation. In some cases, your surgeon may be able to connect to your small intestine to your anus, which will allow you to defecate normally. If that's not possible, a bag attached to the abdomen will be used to collect stool.
Ulcerative colitis is a serious inflammatory bowel disease, but it's symptoms can often be managed with medication, dietary changes and stress relief techniques, allowing you to live a fairly normal life.
Gastroenterologists are concerned with conditions that affect the stomach, intestinal tract, colon and other organs involved in digestion and waste elimination. These conditions include certain types of cancer, biliary tract disease, ulcers and Irritable Bowel Syndrome. The test that checks for these potential health issues is called an endoscopy. There are several different endoscopic procedures that allow your doctor to check the digestive system, including a colonoscopy, enteroscopy and an upper gastrointestinal endoscopy. Find out more about getting an endoscopy and whether it’s time for you to have this test.
What Is an Endoscopy?
During an endoscopy, a long tube is inserted into an orifice (usually the mouth or anus) to look at the organs of the body. The tube, called an endoscope, has a camera that allows your doctor to view the targeted area. In the case of a colonoscopy, the endoscope is inserted into the rectum and provides a visual of your colon and intestines. An enteroscopy views the small intestine and an upper GI endoscopy looks at the parts of your upper intestinal tract, including the esophagus.
What Does an Endoscopy Detect?
An endoscopy can detect polyps (benign and precancerous) as well as cancerous tumors. It can also identify the presence of ulcers, inflammation and other damage to the wall of the intestines or stomach. An upper GI endoscopy can determine the cause of heartburn, chest pain and problems swallowing your food. In some cases, polyps or objects can be removed during the procedure or tissue samples may be taken. A stent can also be inserted in restricted areas of the stomach, esophagus or intestinal tract.
Do You Need this Test?
Here are a few indications that you should see your gastroenterologist soon for an endoscopy:
- You have intense pain in the abdomen or have been diagnosed with digestive problems
- You have severe acid reflux or chronic heartburn
- You feel as if there is some type of blockage in your intestinal tract (such as long-term constipation)
- There’s blood in the stool
- There’s a family history of colon cancer
- You’re over the age of 50
See Your Gastroenterologist
An endoscopy is not a test that you want to delay long if you’re concerned about your stomach, colon and digestive health. Call a gastroenterologist in your area to schedule an initial consultation and exam today.
Gastroenterologists, also called GI doctors, are concerned with a wide array of issues involving the digestive system. One concern for gastroenterologists is precancerous polyps in the colon, rectum and other areas of the intestinal tract. It’s wise to be informed about polyps and how they may affect your gastroenterological and overall health.
What Are Precancerous Polyps?
A polyp is a small, fleshy nodule that forms on the inside of the intestines or colon. It is considered an abnormal growth, but in many cases, they are found to be benign (commonly in the early stages). However, over time polyps can become large and malignant if they aren’t treated. Many polyps are found to be pre-cancerous, which means they have the potential to turn cancerous if they aren’t removed. With early detection through an endoscopic test, the risk can be eliminated by your gastroenterologist.
What Are the Potential Causes?
Doctors aren’t definitively sure what causes polyps to form, but there are a number of theories. Here are a few:
- Heredity (a family history of colon or intestinal problems) or certain hereditary conditions
- Poor diet or lack of nutrition
- Lack of exercise and regular physical activity
- Being overweight or obese
- Diagnosis of ulcerative or Crohn’s colitis
- The natural aging process for some patients (which is why regular exams are recommended after age 50)
What to Do About Them
The good news is that precancerous polyps can usually be quickly and effectively treated by your gastroenterologist. They are diagnosed through an exam called a virtual colonoscopy. A tube called a fiber-optic scope is inserted into the rectum that can identify the presence of a polyp and take a sample for a biopsy. If it is precancerous, your GI doctor can remove the polyp at another colonoscopy appointment. You should make this polyp removal appointment a priority.
Make an Appointment with a Gastroenterologist
The health of your digestive and elimination system is crucial to your overall health. Whether you’re in need of an initial endoscopic test to check for polyps or you’ve already been diagnosed with a precancerous polyp, call a gastroenterologist in your area for an appointment.
When it comes to matters involving your digestive tract, stomach, and colon, a gastroenterologist is the doctor to consult with. GI specialists also help patients with matters involving the pancreas, gallbladder, liver and other organs involved in the elimination of waste. Here are some of the most common frequently asked questions that patients have for gastroenterologists.
What Does a Gastroenterologist Do?
A gastroenterologist is tasked with studying, managing and treating disorders involving the gastrointestinal tract. They diagnose potential problems that stand in the way of your body’s ability to comfortably and easily digest food, move it through the body and get rid of waste. It’s important that your gastrointestinal system is healthy so that your body absorbs the nutrition it needs for energy and vitality. GI doctors undergo rigorous training in this specialized area of medicine for five or six years after medical school.
What Tests Are Needed?
There are a number of tests that a gastroenterologist may recommend depending on your digestive concerns. Here are a few of the most common ones:
- Colonoscopy (checks rectum, colon, and intestinal tract)
- Upper GI endoscopy (checks esophagus and upper gastro system)
- Flexible sigmoidoscopy (similar to a colonoscopy, but only examines a portion of the colon)
- Endoscopic or abdominal ultrasound
- Abdominal Angiogram
- CT enterography
What Treatments Are Administered?
If a problem is identified in the gastrointestinal tract or system, there are a number of possible solutions your GI doctor may explore:
- Polyp removal (done with an endoscope)
- Esophageal, colonic, duodenal or bile duct stent placement (allows the comfortable passage of bodily fluids, solids, and waste)
- Cecostomy (clears bowels)
- Surgical procedures (such as bowel surgery, appendectomy, colostomy, proctectomy, gastric bypass surgery, etc)
Ask More Questions at Your Initial Appointment
Whatever specific questions you may have for a gastroenterologist, they are best addressed at your first visit. You should make this important appointment when recommended by your primary physician or when you have symptoms of a GI problem (bleeding, chronic constipation or diarrhea, heartburn and similar concerns), Call a gastroenterologist in your area to schedule a consultation today.
