Abstract
Introduction: The study aimed to develop consensus recommendations for the safe and appropriate use of liquid nitrogen spray cryotherapy in Barrett's esophagus and esophageal cancer.
Methods: Statements were initially formulated and grouped into categories of indications, training, preprocedure, intraprocedure, and postprocedure recommendations, frequency/timing of repeat procedures, and contraindications. Two investigators assessed the strength of the evidence for each statement using Grading of Recommendations Assessment, Development, and Evaluation methodology. Nineteen experts were invited to participate in a modified Delphi process. For statements that received >80% agreement, minor iterative edits were performed until there was unanimous consensus. If a threshold of 80% agreement was not reached, the statement was modified based on feedback and included in the next Delphi round. Statements were rejected if no consensus was reached after 3 rounds.
Results: After 3 Delphi rounds, 41 of 42 statements were accepted either in their original version (n = 11) or after modification based on expert input (n = 30).
Discussion: Through a modified Delphi process, we developed expert and evidence-based consensus recommendations to guide safe and appropriate use of liquid nitrogen spray cryotherapy in Barrett's esophagus and esophageal cancer.
