Twenty-four patients underwent transnasal upper gastrointestinal endoscopy under local anesthesia and noninvasive assessment of liver fibrosis through elastography and platelet count. Procedure-related pain intensity and anxiety, adverse events, and impact on therapeutic decision-making were analyzed. The procedure was well tolerated, with no adverse events, and periprocedural discomfort and anxiety were minimal-to-mild. Transnasal endoscopy modified therapeutic decisions in 37.5% of cases, compared with the exclusive use of noninvasive methods.
