Capsule Endoscopy: Overview, Preparation, Procedure, Recovery, Risks, and Aftercare
Overview
The capsule endoscopy is a minimally invasive procedure used to visualize the gastrointestinal tract, including the small intestine. As the capsule passes through the digestive system, a camera captures images. In order to identify any abnormalities or signs of gastrointestinal conditions, a healthcare provider monitors these images on a recording device worn by the patient.
Preparation
Among the preparations for capsule endoscopy are:
-
In order to ensure a clear view of the gastrointestinal tract, patients are typically required to fast before the procedure.
-
Patients may need to adjust their medication regimen under the guidance of their healthcare provider if certain medications interfere with the procedure or affect the quality of the images obtained.
-
To improve vision, patients may be instructed to follow a clear liquid diet in the days leading up to the procedure.
Procedure
Endoscopy of the capsule involves:
-
The capsule, which is about the size of a large vitamin pill, is swallowed with a glass of water. It houses a tiny camera that captures images as it passes through the digestive tract.
-
A recording device, typically a belt or harness, is worn by the patient to receive and store the images transmitted by the capsule.
-
Patients can usually resume normal activities while the capsule is in transit, although they may be advised to avoid strenuous exercise to prevent dislodging it.
Recovery
After swallowing the capsule, patients typically can resume their normal activities while waiting for the capsule to pass naturally through the digestive tract. A recording device is worn during the procedure, which may last a few hours to a day, depending on the healthcare provider's instructions.
Risks
Although capsule endoscopy is generally considered safe, there are some potential risks and complications to be aware of:
-
Rarely, capsules can become lodged or retained in the digestive tract, particularly in patients with pre-existing gastrointestinal conditions like strictures or obstructions.
-
A capsule endoscopy may not provide a comprehensive examination of the gastrointestinal tract because it is limited to the small intestine and does not allow direct intervention or biopsy.
Aftercare
Following capsule endoscopy:
-
The patient usually has a follow-up appointment with their healthcare provider to review the images captured during the procedure and discuss any recommendations for further evaluation or treatment.
-
After the procedure, patients are usually able to resume their normal diet and activities, unless their healthcare provider instructs them otherwise.
-
Patients should monitor for any signs of complications, such as persistent abdominal pain, vomiting, or difficulty swallowing, and seek medical attention if necessary.
When patients understand the overview, preparation, procedure, recovery, risks, and aftercare associated with capsule endoscopy, they can approach the procedure with confidence and ensure optimal outcomes.
