BACKGROUND: EGD, with small-diameter endoscopes, is routinely performed via a nasal route in adults. OBJECTIVE: To evaluate a new ultrathin one-plane bending videoendoscope for transnasal EGD. DESIGN: Single center, prospective, randomized study. SETTING: Edouard Herriot University Hospital. PATIENTS: A total of 122 outpatients (median age, 49 years [18-81 years], 62 men and 60 women) were randomized into 2 groups (on a 2:1 basis) according to the endoscope used: (1) a standard 5.9-mm-diameter videoendoscope (80 patients) or (2) a one-plane bending high resolution 4.9-mm-diameter videoendoscope (42 patients). MAIN OUTCOME MEASUREMENTS: The operator assessed the quality of examination by using standard scores or a 100-mm visual scale. Patients quantified tolerance by using a 100-mm visual scale. RESULTS: The duration of the procedure was the same in each group. The feasibility of transnasal insertion was significantly higher when using the 4.9-mm-diameter endoscope (97.61% [41/42 patients] vs 88.75% [71/80 patients], P<.05). The tolerance of EGD was significantly better in the group with the small videoendoscope, for global discomfort, pain, belching, and bloating. Similarly, acceptation of a new EGD in similar conditions was higher in group 2 (92.9% vs 80%, P<.05). The quality of examination (global, lavage, inflation, suction) was not different between the 2 groups. LIMITATIONS: Evaluation of patient tolerance and quality of examination was based on subjective features. CONCLUSIONS: Availability of a new ultrathin one-plane bending videoendoscope represents a major technical improvement for transnasal EGD, which significantly improves both feasibility and patient tolerance, without affecting the quality of the examination.
