What is this test, and why might my healthcare provider recommend it for me?
This test documents and tracks any adverse events or complications that may occur after an upper gastrointestinal endoscopy (EGD). An upper endoscopy is a procedure where a doctor uses a thin, flexible tube with a camera (endoscope) to examine the lining of your esophagus, stomach, and the first part of your small intestine (duodenum). This test helps healthcare providers monitor, classify, and report any complications that might arise following the procedure.
What are the potential adverse events that could happen during or after this test?
While upper endoscopy is generally safe, potential adverse events may include: Bleeding (especially if a biopsy was taken or a polyp was removed), perforation (a small tear in the gastrointestinal wall), reaction to sedatives or anesthesia, infection, sore throat, and very rarely, complications related to existing medical conditions. The overall complication rate is very low, typically less than 1-2% for diagnostic procedures.
What symptoms should I watch for at home once my test has been completed?
After your procedure, contact your healthcare provider immediately if you experience: Severe or worsening abdominal pain, fever or chills, difficulty swallowing, vomiting (especially if it contains blood or looks like coffee grounds), black or tarry stools, chest pain, shortness of breath, or any signs of an allergic reaction to medications.
How are adverse events managed or treated if they occur after this test?
If complications occur, treatment depends on the type and severity. Minor bleeding may stop on its own or require medication. Perforation often requires surgical repair or endoscopic closure. Infections are treated with antibiotics. Your healthcare team will determine the appropriate management based on your specific situation.
Reference range
No adverse events documented; presence of adverse events is coded as 1 (present) or 0 (absent) for specific event typesN/A
Patient should be monitored for adverse events during the recovery period following upper GI endoscopy. Common post-procedure symptoms include sore throat, bloating, and mild discomfort. Instruct patient to report severe abdominal pain, vomiting, fever, difficulty swallowing, or rectal bleeding. Arrange follow-up contact at 24 hours and 7 days post-procedure to assess for delayed complications
