Study Arms:
- EGD-colonoscopy group (Type: ACTIVE_COMPARATOR): In this group, patients receiving an EGD followed by a colonoscopy during a same-day bidirectional endoscopy. Patients receive moderate conscious sedation with fentanyl and midazolam for the procedures. Gastric polypectomy will be provided when gastric polyps are found during an EGD study. Colon polypectomy will be provided when colon polyps are found during a colonoscopy study. Patients' heart rate, respiratory rate, blood pressure, and oxygen saturation will be recorded every 60 seconds during the endoscopic examinations. Patients' tolerability to EGD and colonoscopy examinations will be scaled by patients and endoscopists after the completion of the examinations. Aldrete scores are recorded15 minutes and 25 minutes after entering the recovery room. The recovery time will also be recorded.
