Endoscopic Ultrasound: Overview, Preparation, Procedure, Recovery, Risks, and Aftercare
Overview
By combining endoscopy and ultrasound, endoscopic ultrasound (EUS) produces detailed images of the digestive tract and surrounding organs in a minimally invasive manner. As well as diagnosing and staging gastrointestinal conditions, it is often used to guide therapeutic interventions.
Preparation
In preparation for endoscopic ultrasound, patients may need to follow these steps:
-
To ensure that the stomach and intestines are empty, patients are typically instructed to fast before the procedure.
-
Prior to the procedure, patients may need to temporarily stop taking certain medications, such as blood thinners.
-
During certain procedures, patients may receive anesthesia or sedation to help them relax and minimize discomfort.
Procedure
The following steps are involved in endoscopic ultrasound:
-
A sedative or anesthesia, if necessary, is administered after the patient is positioned on an examination table.
-
An endoscope is inserted through the mouth or rectum and advanced into the digestive tract with a light and camera.
-
A small ultrasound probe is attached to the tip of the endoscope, which emits high-frequency sound waves that create detailed images of the digestive tract and nearby organs.
-
Healthcare providers maneuver the endoscope to obtain images of the esophagus, stomach, duodenum, pancreas, liver, gallbladder, and surrounding lymph nodes.
-
In the event that abnormalities are detected during the procedure, the healthcare provider may perform a biopsy or perform other therapeutic interventions, such as draining fluid collections or injecting medications.
Recovery
After endoscopic ultrasound, patients are typically monitored in a recovery area until the effects of sedation wear off. Some patients may experience mild discomfort, bloating, or gas after the procedure, but these symptoms typically subside shortly afterward. Within a few days of the procedure, most patients can resume regular activities.
Risks
There are some risks associated with endoscopic ultrasound, including:
-
Bleeding or perforation of the gastrointestinal tract
-
Infection
-
Adverse reactions to sedation or anesthesia
Despite being rare, these risks should be discussed with a healthcare provider before undergoing the procedure.
Aftercare
Patients may be advised to follow these steps after endoscopic ultrasound:
-
Due to the effects of sedation, avoid driving or operating heavy machinery for the remainder of the day.
-
Any dietary or medication instructions provided by their healthcare provider should be followed.
-
Discuss the results of the procedure and any further treatment plans at follow-up appointments.
Conclusion
A diagnostic and therapeutic tool for assessing gastrointestinal conditions and guiding treatment decisions, endoscopic ultrasound is an excellent tool. A combination of endoscopy and ultrasound technology allows healthcare providers to accurately diagnose and stage various diseases by providing detailed images of the digestive tract and surrounding organs. Consult your healthcare provider before undergoing endoscopic ultrasound if you have any questions or concerns.
