Who Needs A Capsule Endoscopy?

When it comes to diagnosing gastrointestinal issues, methods like traditional endoscopy have been the standard treatment approach. However, capsule endoscopy has emerged as a better alternative in the past few years.

The procedure has revolutionised the way doctors examine the small intestine – a part of the digestive system that is often difficult to reach for diagnosing abnormalities.

But who needs capsule endoscopy? In this blog, we will explore what it is, when it is recommended and how it helps in the treatment of various conditions.

What Is Capsule Endoscopy?

Capsule endoscopy is a procedure that allows doctors to view the gastrointestinal tract (GI) through a small-sized camera fitted inside a vitamin-sized pill.

During the procedure, patients are asked to swallow the capsule. Once ingested, it travels through the digestive tract, taking thousands of pictures which are then transmitted to the recorder worn by the patient around the waist. The healthcare provider visualises the images to find out the abnormalities.

Within 24 hours, the capsule is naturally excreted from the body through the stool. Capsule endoscopy requires no sedation or recovery time, making it one of the safest options for diagnosing gastrointestinal problems.

When Is Capsule Endoscopy Suggested?

There are specific conditions when capsule endoscopy is recommended for patients.

• Unexplained gastrointestinal bleeding: This is one of the major reasons to perform capsule endoscopy. The examination helps to identify the source of hidden gastrointestinal bleeding. The small intestine is sometimes affected by ulcers or small tumours that cause slow blood loss.
• Suspected Crohn’s disease: Crohn’s disease is a condition that causes inflammation and irritation in any part of the digestive tract, especially the small intestine. When symptoms like abdominal pain, weight loss, or diarrhoea go undetected by other tests, a capsule endoscopy is suggested to diagnose the signs of inflammation.
• Small bowel tumours: Capsule endoscopy is one of the effective procedures that help in diagnosing bowel tumours, including polyps, neuroendocrine tumours, or carcinoid tumours that are not possible to identify by other imaging techniques.
• Celiac disease: Capsule endoscopy provides good-quality images of the small bowel mucosa, especially for patients who are unable to undergo traditional endoscopy for duodenal biopsy. The procedure helps the doctor to look for complications such as ulcers or intestinal damage related to Crohn’s disease.
• Monitoring the conditions: Capsule endoscopy is not just about diagnosing the condition; it is also about monitoring the progress of treatment of gastrointestinal conditions.

Who Is Not An Eligible Candidate For Capsule Endoscopy?

Capsule endoscopy is a safe and effective procedure. However, for some patients, other diagnostic procedures are suggested to ensure safety and the best outcome.

• In pregnant women, its effectiveness has not been studied yet.
• Patients with bowel obstructions or strictures
• Those with swallowing difficulties, since the patients have to swallow the pill.
• Patients with pacemakers or defibrillators.

Pre-Operative Measures Before Capsule Endoscopy

Before capsule endoscopy, patients are required to follow certain guidelines for a successful examination.

• Fasting: Patients are required to avoid eating solid foods at least 12 hours prior to the procedure. This ensures that the stomach and the small intestine are free from food.
• Bowel clearance: A laxative might be prescribed for proper bowel movement. This makes sure that the images taken are of high quality.
• Medications: Patients are advised to inform the doctor about any medications they are taking to prevent complications.

Conclusion

Capsule endoscopy is a breakthrough in diagnosing gastrointestinal disorders. It offers a painless and non-invasive way to view the digestive system for appropriate treatment. If you are suffering from unexplained issues related to the stomach, consult an experienced gastroenterologist to discuss whether capsule endoscopy is right for you.
