Clinical Trial Summary

This study compares patients' acceptability and safety of two established endoscopic methods for treating dysplastic Barrett's esophagus: radiofrequency ablation versus hybrid argon plasma coagulation.

Description:

Both endoscopic radiofrequency ablation (RFA) and argon plasma coagulation (APC) are established treatment modalities for dysplastic Barrett's esophagus. Recently, a modification of the APC method has emerged, which involves a submucosal injection of saline preceding the thermal ablation (hybrid-APC; h-APC). This allows to increase the procedure's safety and presumably reduces the patients' post-procedural discomfort. Although both RFA and h-APC are characterized by high effectiveness in eradicating Barrett's segments, limited data compares the patient-related aspects of the procedures. To fill this knowledge gap, we set out a single-center randomized-controlled trial to compare procedural acceptability, safety, and impact on the quality of life, of the two methods.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Level of post-procedural pain	Change in chest pain evaluated by the numeric analog scale (NAS) from score 0 (no pain) to 10 (worst possible pain) before the procedure and immidietly after (30-60 minutes) the procedure.	Measured at any time point before given anesthesia for the procedure and immidietly after the procedure.
Primary	Level of post-procedural pain at day 7 after treatment	Post-procedural chest pain evaluated by the numeric analog scale (NAS) from score 0 (no pain) to 10 (worst possible pain)	Measured at day 7 after the procedure
Primary	Level of late post-procedural pain (at day 30 after treatment)	Post-procedural chest pain evaluated by the numeric analog scale (NAS) from score 0 (no pain) to 10 (worst possible pain)	Measured at day 30 after the procedure
Secondary	Level of post-procedural dysphagia	Evaluated by the Mellow-Pinkas scoring from 0 (able to eat normal diet / no dysphagia) to 4 (unable to swallow anything / total dysphagia)	Measured before the procedure, immidietly after (30-60mins), and at day 7, and day 30 after the procedure.
Secondary	Level of post-procedural quality of life	Evaluated by the QLQ-OES18 questionnaire specific for esophageal symptoms, and consists of a symptom scale only. The QLQ-OES18 includes 18 questions: 6 single item subscales relating to saliva swallowing, choking, dry mouth, taste, coughing, and talking. It also includes 12 items grouped into 4 subscales: dysphagia (3 items), eating (4 items), reflux (2 items), and pain (3 items).	Measured before the procedure, immidietly after (30-60mins), and at day 7, and day 30 after the procedure.
Secondary	The rate of complications	Intra-procedural complications, such as bleeding, perforation, post-procedural complications, e.g. chest-pain, esophageal stricture will be monitored during the hospital stay and follow-up at day 7 and day 30 after the procedure (phone call).	Measured during the prcoedure, immidietly after the procedure and at day 7 and day 30 after the procedure during follow-up
