What is small bowel endoscopy? How does it differ from a colonoscopy? What can you expect during the procedure? Get all the answers to your questions about this important diagnostic tool.

Understanding Small Bowel Endoscopy

Small bowel endoscopy, also known as deep endoscopy, is a minimally invasive procedure used to examine the entire small intestine, which is approximately 20 feet long. This specialized technique employs an endoscope – a thin, flexible tube with a light and video camera – that is equipped with inflatable balloons. These balloons allow the endoscope to navigate through the small bowel, enabling doctors to thoroughly inspect and diagnose any issues present.

Differentiating Small Bowel Endoscopy from Colonoscopy

While both small bowel endoscopy and colonoscopy are types of endoscopic procedures, they serve distinct purposes. Colonoscopy focuses on examining the large intestine (colon), whereas small bowel endoscopy is designed to investigate the entire small intestine. This makes small bowel endoscopy particularly valuable for diagnosing conditions like Crohn’s disease, which can affect any part of the digestive tract.

Preparing for Your Small Bowel Endoscopy

Prior to your small bowel endoscopy, your doctor will provide specific instructions on how to prepare. This may involve fasting (not eating or drinking) for a period before the procedure to ensure an empty stomach. Additionally, if you take blood-thinning medications, you may need to temporarily stop taking them to minimize the risk of bleeding during the endoscopy.

What to Expect During the Procedure

On the day of your small bowel endoscopy, you will be given sedation by an anesthesiologist to ensure your comfort throughout the procedure. Your doctor will then carefully guide the endoscope through your mouth, down your esophagus, and into the small intestine. You will not feel any pain during the endoscopy, which typically lasts between one and two hours.

Post-Procedure Care and Recovery

After the endoscopy, you will rest until the sedation wears off. Since you will not be able to drive, it is important to arrange for someone to take you home. Most people are able to resume their normal activities within a day or two, although your doctor may provide specific guidelines based on your individual case.

The Benefits of Small Bowel Endoscopy

Small bowel endoscopy is a valuable diagnostic tool that allows doctors to thoroughly examine the entirety of the small intestine. This comprehensive view can help identify the underlying causes of various gastrointestinal issues, such as Crohn’s disease or celiac disease, and guide appropriate treatment. By utilizing this advanced technique, healthcare providers can provide more accurate diagnoses and tailored care for their patients.

Frequently Asked Questions

What is the difference between a small bowel endoscopy and a colonoscopy? A small bowel endoscopy focuses on examining the entire small intestine, while a colonoscopy is used to view the large intestine (colon).

How long does a small bowel endoscopy procedure take? Typically, a small bowel endoscopy lasts between one and two hours.

Will I feel any pain during the small bowel endoscopy? No, you will not feel any pain during the procedure as you will be sedated throughout the process.

When can I resume normal activities after a small bowel endoscopy? Most people are able to return to their regular activities within a day or two, but your doctor will provide specific guidance based on your individual case.

Why is small bowel endoscopy an important tool for diagnosing gastrointestinal issues? Small bowel endoscopy allows for a comprehensive examination of the entire small intestine, which is crucial for identifying and diagnosing conditions like Crohn’s disease or celiac disease that can affect any part of the digestive tract.

How does the doctor navigate the small bowel during the endoscopy? The endoscope used in small bowel endoscopy is equipped with inflatable balloons that help the doctor move the endoscope through the small intestine for a thorough examination.

Is there any special preparation required for a small bowel endoscopy? Yes, you may need to fast (not eat or drink) for a period before the procedure, and you may need to temporarily stop taking certain medications, such as blood thinners, as directed by your doctor.

Small Bowel Endoscopy | Inflammatory Bowel Disease | Henry Ford Health

Minimally invasive procedure for diagnosing IBD.

Your small intestine, also known as the small bowel, connects the stomach to the large intestine (colon). The small bowel is often the site of painful conditions, such as Crohn’s disease or celiac disease (an immune disease in which eating foods with gluten leads to damage in the small intestine).

At Henry Ford, we use several diagnostic procedures to determine the cause of your discomfort, where in your digestive tract the issue is located and how severe the issue is. One of these procedures is small-bowel endoscopy, also known as deep endoscopy. Some other digestive centers don’t offer small-bowel endoscopy because of the time and coordination involved in the procedure, but it’s a valuable tool that helps us accurately diagnose our patients.

Our team includes specialists in inflammatory bowel disease (IBD) with the expertise you need for a precise diagnosis and comprehensive treatment. No matter what’s causing your symptoms, we’re here to help.

What is a small-bowel endoscopy?

A small-bowel endoscopy is a minimally invasive procedure in which we examine your entire small intestine, which is about 20 feet long. We use special balloons that fit over a thin, flexible tube called an endoscope, which has a light and a video camera. By inflating and deflating the balloons, we move the small bowel over the endoscope so we can examine it.

The endoscope lets us see nearly any part of the small bowel so we can diagnose the cause of your symptoms. We also can treat your condition if needed with the help of tiny tools we pass through the endoscope and into your small bowel.

What’s the difference between a small-bowel endoscopy and a colonoscopy?

While small-bowel endoscopy and colonoscopy are both types of endoscopy, the procedures are very different. Because Crohn’s disease can affect any part of the digestive tract, we use small-bowel endoscopy for its greater ability to view any part of the digestive tract. Colonoscopy, by contrast, lets us view changes and areas of concern in the large intestine (colon) only.

Because of a colonoscopy’s more limited viewing area, a small-bowel endoscopy is the better choice for locating and diagnosing Crohn’s disease.

What to expect during your small-bowel endoscopy

Before your procedure, we’ll give you instructions on how to prepare for your small-bowel endoscopy. You may need to fast (not eat or drink) before your endoscopy so your stomach is empty for the procedure.

If you take certain blood-thinning medications, you may need to stop taking them in the days before your endoscopy, as these medications can increase your risk of bleeding during the procedure. Your doctor will give you instructions about any medications you may take for chronic conditions, such as diabetes, heart disease or high blood pressure.

On the day of your procedure, one of our expert anesthesiologists will sedate you. While you’re sedated, your doctor will pass the endoscope through your mouth and stomach and into the small intestine. You will not feel any pain during your endoscopy.

The procedure will last an hour or two. Afterward, you’ll rest until your sedation wears off. You won’t be able to drive, so please plan on having someone available to take you home.

  What is endoscopy?

  Endoscopy is a procedure in which the gastro-intestinal tract (GI tract) is viewed through a lighted, flexible tube with a camera at the end (endoscope). Small samples of tissues cells (biopsy) can also be collected and sent for testing.

  There are two basic types of endoscopy:

  1. Upper endoscopy – The esophagus, stomach, and small intestines can be viewed by a thin flexible tube inserted through the mouth.
  2. Colonoscopy – The lining of the large intestine, colon and rectum can be viewed by a flexible tube inserted through the rectum.

  Preparation

  • Blood tests are sometimes required.
  • Medications can be given by vein if needed.
  • Please arrange for a ride home. You may feel drowsy after the procedure due to medications.
  • Upper endoscopy: No food or drink is allowed for six hours before the procedure. An empty stomach allows for the best view and safest exam.
  • Colonoscopy: Drink only clear liquids for at least 24 hours before the procedure. A laxative or special cleansing solution will be ordered by the physician to clear the bowel of stool so that the rectum/intestines can be seen. (See below for specific instructions)

  Day of procedure

  • The doctor will explain the procedure and get your consent.
  • Tell your doctor about medications you are taking.
  • Discuss allergies to medications and other medical conditions.
  • This is the time to ask questions about procedure.

  What can I expect during upper endoscopy?

  Your doctor will spray your throat with a local anesthetic or give you a sedative to help you relax. You’ll then lie on your side, and a doctor will pass the endoscope through your mouth and into the esophagus, stomach and duodenum. The endoscope doesn’t interfere with your breathing. Most patients consider the test only slightly uncomfortable, and many patients fall asleep during the procedure.

  What happens after upper endoscopy?

  You will be observed closely until most of the effects of the medication have worn off. Your throat might be a little sore, and you might feel temporarily bloated due to the air introduced into your stomach during the test. You will be able to eat after you leave unless your doctor instructs you otherwise.

  Your doctor generally can tell you your test results on the day of the procedure; however, the results of some tests might take several days.

  If you received sedatives, you won’t be allowed to drive after the procedure even though you might not feel tired. You should arrange for someone to accompany you home because the sedatives may affect your judgment and reflexes for the rest of the day.

  What happens during colonoscopy?

  Colonoscopy is well-tolerated and rarely causes much pain. You might feel pressure, bloating or cramping during the procedure. You will likely receive a sedative to help you relax and better tolerate any discomfort.

  You will lie on your side or back while your doctor slowly advances a flexible tube (colonoscope) through your large intestine to examine the lining. The whole procedure itself usually takes 45 to 60 minutes, although you should plan on two to three hours for waiting, preparation and recovery.

  What happens after a colonoscopy?

  Your physician will explain the results of the examination to you, although you’ll have to wait for the results of any biopsies performed. If you were given sedatives during the procedure, someone must drive you home and stay with you. Even if you feel alert after the procedure, your judgment and reflexes could be slow for the rest of the day. You may have some cramping or bloating because of the air introduced into the colon during the examination. This should disappear quickly when you pass gas.

  You should be able to eat after the examination, but your doctor may restrict your diet and activities, especially after the removal of any polyps.

What is bowel endoscopy: how to prepare and undergo an examination, indications and contraindications

Bowel endoscopy is a type of diagnostic examination that allows you to see the state of this organ from the inside. It is performed using an endoscope – a flexible device equipped with light, a camera, and in some cases a needle for biopsy (taking a tissue sample for examination in a laboratory).

Types of endoscopy

There are several main types of endoscopic examination of the intestine:

• Capsule – used to examine the small intestine; the patient swallows the capsule, which contains a camera that takes pictures as it moves; data is transmitted using a sensor, and the capsule itself subsequently leaves the body naturally
• Colonoscopy – endoscopic examination of the large intestine; a tube of small diameter and long length (up to one and a half meters) is inserted through the rectum
• Esophagogastroduodenoscopy – used to examine the esophagus, stomach, and the initial area of ​​the small intestine; during the procedure, a gastroscope (a type of endoscope) is inserted into the patient through the oral cavity and pharynx to a depth of 30 cm
• Sigmoidoscopy – endoscopic examination of the rectum; during the procedure, an endoscopic device

is inserted through the rectum to a depth of 30 centimeters

Indications for bowel endoscopy

Each type of bowel endoscopy is used to identify different diseases:

• Capsule
• Bleeding from the area of ​​the small intestine
• Crohn’s disease
• Iron deficiency anemia
• Neoplasms of the small intestine
• Colonoscopy
• Discharge of blood, mucous or purulent masses from the intestines
• Pain in the anus
• Inflammation, colitis
• Change or disturbance of stool
• Esophagogastroduodenoscopy

• Gastritis
• Bleeding
• Violation of the digestive tract
• Suspicion of a malignant tumor
• Sigmoidoscopy
• Chronic hemorrhagic disease
• Probability of neoplasm in large intestine
• Paraproctitis
• Suspected prostate tumor (in men)

The doctor may also send the patient for an endoscopic examination of the colon, small intestine, or rectum if symptoms such as:

• Abdominal pain of unknown origin
• Foreign body in intestines
• Gastric or intestinal obstruction
• Weight loss with anemia, high fever
• Bleeding from the gastrointestinal tract

Endoscopy can also be done to monitor results after surgery.

Contraindications

Endoscopic examination of the intestine is not performed if the patient:

• Diagnosed with severe ulcerative colitis
• Impaired blood clotting
• Bowel perforation suspected
• Abnormal enlargement of the colon (toxic megacolon)
• State of shock
• Severe mental disorders
• Inflammatory or edematous lesions of the areas through which the endoscope will be inserted
• Acute heart disease

Preparing for your procedure

Preparing for an endoscopic examination of the intestine consists of two main steps:

• Diet 2 days before procedure
• Cleansing the gastrointestinal tract from food debris and feces on the eve of the procedure

Diet includes:

• Lean boiled fish or chicken
• Dairy products
• Lean biscuits (biscuits, etc. )

Should be eliminated from the diet:

• Milk
• Black bread
• Kvass
• Legumes (beans, peas, etc.)

Endoscopy – what it is, what are the advantages

Endoscopy is an invasive method for examining hollow organs using endoscopes – flexible tubes equipped with a light source and passages for inserting surgical instruments. Endoscopic research methods are widely used in proctology, gastroenterology, otolaryngology, oncology, surgery and other areas of medicine.

The uniqueness of the method is due to its accuracy and information content. During the procedure, the doctor can take the material for a histological examination, carry out a number of therapeutic measures, and reliably assess the condition of the membranes lining the organ. Endoscopy – what kind of procedure it is, what are the advantages – experts will answer these and other questions in the article below.

Possibilities of endoscopy

Endoscopy is considered a universal method for detecting diseases of hollow organs and entire systems. The procedure is prescribed as a primary or differential diagnosis. The possibilities of endoscopic examination are wide:

• early diagnosis of structural changes in mucous membranes, tumors;
• detection of erosive foci, polyps, diverticula, ulcers;
• determination of infectious and inflammatory foci;
• tissue biopsy with biopsy sampling for histological analysis;
• administration of drugs for the purpose of antibacterial or antiseptic treatment of a hollow organ;
• laser treatment, cryodestruction method (for example, when removing polyposis formations).

Thanks to endoscopy, low-traumatic surgical interventions, catheterization, bypass procedures can be performed.

Scope

Rigid or flexible endoscopes (fiberscopes) are used in endoscopy. Flexible have a fiberglass structure – an image conductor to a computer.

Today, video endoscopes equipped with a miniature video camera are more commonly used. The device transmits information to the computer in real time. The tube of rigid endoscopes is made of metal. Main types of endoscopes:

• arthroscope – study of articular structures;
• hysteroscope for examining the internal female genital organs;
• colonoscope – allows you to examine the large intestine;
• proctosigmoscope – the equipment allows diagnosing diseases of the rectum and sigmoid colon;
• tracheobronchoscope – examines the airways;
• laparoscope – used in the diagnosis of diseases of the peritoneum and abdominal space;
• gastroscope (esophagogastroduodenoscope) – the equipment allows you to evaluate the organ complex of the upper digestive tract;
• cystoscope – a device used in urology, nephrology and gynecology for the diagnosis of diseases of the genitourinary system.

The endoscopy procedure is named according to the equipment chosen. So, when using a colonoscope as part of the diagnosis of proctological diseases, they talk about colonoscopy, when using an arthroscope, about conducting arthroscopy, if necessary, studies of the gastrointestinal tract suggest fibrogastroduodenoscopy.

How an endoscopy is done

Endoscopic examination is carried out through natural anatomical passages. The procedure is often performed under local anesthesia to maintain patient contact on an outpatient basis. Sometimes the question of the need for anesthesia is decided.

In some cases, such as laparoscopy, the insertion of the equipment is carried out through punctures. In this case, patients are in the hospital until the state of health normalizes.

Endoscopic technique is widely used for appendicitis, removal of the gallbladder, tumors, heart bypass. Endoscopy in surgery reduces the invasiveness of the operation, accelerates the recovery of patients and minimizes intra- and postoperative complications.

The most common endoscopic examinations

Most often, endoscopy is performed in gastroenterological and proctological practice. These studies are distinguished by their availability and good tolerability by patients. How is endoscopy performed in the study of the upper and lower digestive tract, the genitourinary system.

FGDS or fibrogastroduodenoscopy

Performed when the patient complains of discomfort and pain in the stomach, in preparation for abdominal surgery, for dynamic control of the prescribed treatment. The procedure is performed on an outpatient basis and lasts no more than 5 minutes.

The gastroscope is inserted into the patient through the oropharynx, having previously treated the throat with a solution of lidocaine. The patient is fitted with a mouthpiece, which must be clamped with teeth. At the deep entrance, the endoscope is immersed through the esophagus to the stomach. Inspection is carried out with the injection of air into the cavity of the stomach to straighten the mucous membranes for better visualization.

At the end of the examination, the doctor makes a conclusion. If necessary, take pictures, fix the nuances of the study.

Intestinal examination

Endoscopy of the intestine or colonoscopy is a common method for detecting diseases of the large intestine, various pathological changes in the membranes. Examination of the lining mucous membranes and the walls of the organ is performed using a flexible endoscope for therapeutic and diagnostic purposes. Indications for intestinal endoscopy are:

• heaviness during emptying, constipation, episodes of intestinal obstruction;
• ulcerative erosive process;
• bleeding of the digestive tract;
• pain;
• polyps, neoplasms.

In diseases of the rectum in the sigmoid segment of the intestine, sigmoidoscopy is indicated. The study is carried out using a proctoscope – a tube with a lighting device and an air injection mechanism. Sigmoidoscopy allows you to assess the length of the intestine up to 22-30 cm from the entrance to the anus.

Genitourinary system

Endoscopy in urology or gynecology is a ureteroscopy or cystoscopy procedure. Both methods can detect diseases of the bladder and urinary tract.

Cystoscopy allows you to evaluate the function of the kidneys, the condition of the bladder, the presence of foreign bodies, foci of ureteral stricture. With the help of a cystoscope, it is possible to carry out procedures for instilling the bladder with antibacterial drugs, antiseptics for chronic cystitis, install a urethral catheter, and take tissues for histological examination.

Today, endoscopy is the method of choice in the diagnosis of hollow organs, along with ultrasound examination. The procedure has a wide range of indications and possibilities. After an endoscopic examination, the reliability of the final diagnosis increases dramatically. Modern diagnostic approaches minimize discomfort and pain for patients.
