Tokyo, Aug. 22 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000062650) titled 'Positive-pressure ventilation under general anesthesia narrows the endoscopic field during esophageal endoscopic submucosal dissection: a blinded paired image analysis' on Aug. 21.

Study Type: Observational

Primary Sponsor: Institute - St Luke's International Hospital

Condition: Condition - Superficial esophageal cancer Classification by malignancy - Malignancy Genomic information - NO

Objective: Narrative objectives1 - General anesthesia with positive-pressure ventilation may narrow the esophageal lumen during ESD compared with intravenous sedation. This study investigated whether this perceived narrowing reflects an actual change in the endoscopic field. Basic objectives2 - Others

Eligibility: Age-lower limit - Not applicable Age-upper limit - Not applicable Gender - Male and Female Key inclusion criteria - It included consecutive patients who underwent esophageal ESD under GA between August 2023 and December 2025 Key exclusion criteria - A patient was eligible when the same lesion had also been examined at a preceding outpatient surveillance endoscopy performed under intravenous sedation with the same endoscope model, and when at least four consecutive images were available at each examination from the moment the lesion first entered the field; patients not meeting these criteria were excluded. Target Size - 50

Recruitment Status: Recruitment status - No longer recruiting Date of protocol fixation - 2026 Year 04 Month 01 Day Date of IRB - 2026 Year 05 Month 01 Day Anticipated trial start date - 2026 Year 04 Month 01 Day Last follow-up date - 2026 Year 07 Month 31 Day
