Vomiting, pressure, and bloating are normal discomforts during/after the exam.
The patient should be observed for:
- bleeding if a biopsy is taken or polyps are removed
- vomiting blood, black and tar-like stool, or intense stomach pain. If the patient has returned home, the patient is recommended to contact the hospital immediately.
The patient may eat/drink 1 hour (at the earliest) after the exam due to the local anesthetic in the throat. For an outpatient exam, the patient may return home after 1-2 hours.
Tissue sample results are available after 1-4 weeks. Further follow-up and treatment should be scheduled, if necessary.
