The results of the procedure or probable findings are often available to the patient prior to discharge from the endoscopy suite or the recovery area. The results of tissue biopsies or cell tests (cytology) will take from 72–96 hours. Normal results will show that the esophagus, stomach and duodenum are free of strictures, ulcers or erosions, diverticula, tumors, or bleeding. Abnormal results include the presence of any of these problems, as well as esophageal infections, fissures, or tears. An increasingly common finding is medication-induced esophageal injury, caused by tablets and capsules that have lodged in the esophagus. These injuries are thought to be associated with damage to the esophageal tissue from gastrointestinal reflux disease (GERD) and the related exposure of the esophagus to large amounts of stomach acid.
