What Is Capsule Endoscopy?
Endoscopy means “seeing inside” in Latin. The procedure allows your healthcare provider to see the inner surfaces of your gastrointestinal tract. What makes capsule endoscopy, sometimes called a pill-cam, different from conventional tube endoscopy is the kind of camera involved. With capsule endoscopy, you swallow a tiny camera encased in a clear, smooth shell; the camera takes pictures of your digestive system as it moves down your esophagus, into your stomach, and through your small intestine.
As the pill-sized camera moves through your digestive system, it transmits thousands of images to a recording device you wear around your waist or neck. At Manhattan Gastroenterology, we offer services based on the indication and will be glad to speak with you about its uses in detail.
What Can Capsule Endoscopy Do It and Why Is It Beneficial?
Traditional endoscopy and colonoscopy procedures give your doctor the ability to examine the upper and lower portions of your gastrointestinal tract, but seeing the middle portions, including the duodenum, jejunum, and ileum of the small intestine, was once unreachable to cameras. Capsule endoscopy sheds light on the middle regions of the gastrointestinal tract without exploratory surgery. Swallowing the tiny camera can reveal the source of gastrointestinal bleeding, detect bowel inflammation from Crohn’s disease, find tumors and see ulcers. People who may have celiac disease can benefit from this type of endoscopy to get a definitive diagnosis and monitor intestinal inflammation without an invasive procedure.
What Happens During Capsule Endoscopy?
The diagnostic procedure is almost as simple as swallowing a pill the size of a large vitamin tablet. Still, this capsule contains lights, a wireless transmitter, and a camera housed in clear plastic. GI doctors will fit you with a monitoring device to wear as the pill moves through you. Some monitors are connected to adhesive patches the healthcare provider will place on your abdomen. For the next 12 hours, you will wear the monitoring device as the capsule moves slowly through your gastrointestinal tract.
★ ★ ★ ★ ★I was experiencing a lot of discomfort, and my doctor recommended Manhattan Gastroenterology for me. I went there, and they recommended I have an endoscopy. It was not nearly as uncomfortable an experience as I thought, and the facility was very modern. They discovered that I had gastritis and recommended some changes in my diet, and told me to avoid stress. If I ignored it, it could have become worse. I feel much better today, thanks to this gastroenterologist.
You will not feel any unusual sensations during the test, but the camera you have swallowed will be working overtime. During a typical test, the camera takes about 50,000 pictures of your stomach and intestinal walls. Like a camera flash, the LED lights in the capsule provide light for the images the camera takes and transmits to the compact monitoring device you wear.
After the wireless camera completes its tour of your stomach, small intestine, and colon, it is expelled. The capsule may emerge after a few hours, or it may not make its reappearance for up to 72 hours; both possibilities are normal. The camera is disposable and can be flushed, so you do not need to retrieve it. The information it gathered is stored in the monitoring device, not the capsule.
How to Prepare for Capsule Endoscopy?
You should consult the physician performing this exam for specific instructions about your preparation given your particular case. The camera capsule works best in an environment free of matter that could obscure the lens, so your doctor will probably recommend that you consume only clear liquids for 24 hours before the test and drink only water on the day of the procedure. Some physicians suggest a laxative before the examination for better visual.
It would help if you spoke with the performing gastroenterologist for specific instructions. Please talk with your practitioner about any medications you take; some of them may have to be adjusted or temporarily discontinued for your test. Some common medications, including non-steroidal anti-inflammatory medications, aspirin, bismuth subsalicylate antacids, and iron supplements, can obscure test findings. Please discuss your medication regimen with your doctor.
On the day of the procedure, your doctor will apply the adhesive sensors that detect the camera’s transmissions and send them to the recording device.
The monitoring device is about the size of a small compact disc player and attaches at the waist with hook-and-loop fasteners. Once your monitoring system is in place, you are ready for the camera capsule.
The pill-sized camera is no larger than a typical multivitamin tablet and should be easy to swallow for most patients. It has a slippery coating to help it go down more easily, and after the health expert sees that the capsule is in place and functioning, you can leave the office.
Follow your doctor’s instructions about eating and drinking while undergoing capsule endoscopy. Generally, you can have clear liquids for the first two hours after swallowing the tablet and a light meal four to six hours after starting the procedure. Your doctor may ask you to avoid strenuous activity that could lead to blurred images, but otherwise, you should be able to go about your usual routine until the test is complete.
What to Expect After the Procedure?
When the test is finished after approximately 12 hours, you can remove the sensor patches and pack them with the monitoring device according to your doctor’s directions. After your healthcare professional uploads the images and analyzes them, you will receive the test results. In most cases, you will get a call about your results within a few days to a week, but some diagnoses take more time.
Advantages of Capsule Endoscopy
Because you need no anesthesia for capsule endoscopy, the procedure involves no recovery time. For many patients, swallowing a pill is considerably more pleasant than undergoing conventional endoscopy. The middle portions of your gastrointestinal tract are difficult to see by other means, but capsule endoscopy creates a detailed, up-to-date image of your intestinal lining. Conditions that can be challenging to diagnose by other means are often readily revealed by capsule endoscopy.
Limitations of Capsule Endoscopy
Your doctor may recommend additional tests to compensate for the limitations inherent with capsule endoscopy. Because the wireless camera capsule is not under voluntary control, the images it records may not highlight an area of interest sufficiently, necessitating further testing. Unlike traditional endoscopy, the camera can only record, so taking a biopsy or removing a polyp is not possible with this procedure. Slow transit can also be a limitation. Sometimes the capsule moves slowly through the bowel and does not examine the entire small bowel before the battery dies. There may also be missed lesions because of irregularities in areas of the small intestine that can be missed either because of inconclusive imaging or rapid transit.
Capsule Endoscopy Complications
Complications with this non-invasive procedure are uncommon, and the test is contraindicated for some patients. If the capsule does not make it through the entire small intestine, you may need an XR to make sure ultimately it eliminated from your intestines. You will need to discuss this with your doctor.
Although complications can occur, they are rare when a specially trained and experienced gastroenterologist conducts the test. However, there can be limitations and complications with its use which may include the following:
- Bowel obstruction-The most serious complication is if the capsule gets stuck inside your digestive tract in an area of narrowing, resulting in a bowel obstruction that may require surgical removal. This can happen in stricture or narrowing your digestive tract from inflammation, prior surgery, or tumor. It’s important to recognize the obstruction early from symptoms such as unusual bloating, abdominal pain, nausea, or vomiting. Other complications include developing a fever after the test, having trouble swallowing, or experiencing chest pain. Call your doctor immediately if you have any such symptoms.
- Slow transit– Sometimes, the capsule moves slowly through the bowel and does not examine the entire small bowel before the battery dies
- Missed Lesions– There can be irregularities in areas of the small intestine that can be missed either because of inconclusive imaging or rapid transit
Call your doctor immediately if you have any such symptoms. If you have had bowel obstructions or adhesions in the past or have a pacemaker, please let your doctor know. Your gastroenterologist at Manhattan Gastroenterology should help decide if a small bowel capsule is a right test for you to come to an accurate diagnosis and treatment plan.
