Unsedated transnasal endoscopy with ultrathin endoscope as a screening tool for research studies

Early experience with unsedated ultrathin 4.9 mm transnasal gastroscopy: a pilot study.

BACKGROUND Unsedated transnasal gastroscopy is a technique with unverified clinical advantages. OBJECTIVE To evaluate the efficacy and procedure times with transnasal gastroscopy by physicians with no previous experience in transnasal endoscopy. METHODS Unsedated transnasal gastroscopy using 4.9 mm ultrathin transnasal gastroscopes with randomization to two different biopsy forceps was pros...

A randomized trial of topical anesthesia comparing lidocaine versus lidocaine plus xylometazoline for unsedated transnasal upper gastrointestinal endoscopy.

BACKGROUND The optimal topical anesthesia regimen for unsedated transnasal endoscopy is unknown. The addition of a nasal decongestant, such as xylometazoline (X), to a topical anesthestic may improve patient comfort. OBJECTIVE To determine the effectiveness of lidocaine (L) versus L plus X (LX) for anesthesia in unsedated transnasal endoscopy. METHODS Consecutive participants of the Aklavik...

Transgastrostomal Observation and Management Using an Ultrathin Endoscope After Percutaneous Endoscopic Gastrostomy

Recent developments have made ultrathin endoscopes available for routine esophagogastroduodenoscopy and also for unsedated transnasal observation (Shaker, 1994). Transnasal endoscopy is known to be less of a burden for patients (more tolerable) than transoral endoscopy and has benefits including fewer effects on respiratory and cardiovascular status and reduced recovery time after the procedure...

A proposal for grading nasomucosal injury as a complication of transnasal endoscopy.

duodenoscopy (EGD) using an ultrathin scope has been developed as an alterna− tive method to conventional endoscopy with sedation [1,2]. Several studies have reported the benefit of transnasal EGD, which may reduce the risk of cardiopul− monary complications, lower the cost related to postprocedure monitoring, and be better tolerated by the patients [1 ± 3]. However, lack of data regarding the ...
