North American Expert Consensus on the Post-procedural Care of Patients After Per-oral Endoscopic Myotomy Using a Delphi Process.

ABSTRACT

BACKGROUND & AIMS: There is significant variability in the immediate post-operative and long-term management of patients undergoing per-oral endoscopic myotomy (POEM), largely stemming from the lack of high-quality evidence. We aimed to establish a consensus on several important questions on the after care of post-POEM patients through a modified Delphi process. METHODS: A steering committee developed an initial questionnaire consisting of 5 domains (33 statements) post-POEM admission/discharge, indication for immediate post-POEM esophagram, peri-procedural medications and diet resumption, clinic follow-up recommendations, and post-POEM reflux surveillance and management. A total of 34 experts participated in the 2 rounds of the Delphi process, with quantitative and qualitative data analyzed for each round to achieve consensus. RESULTS: A total of 23 statements achieved a high degree of consensus. Overall, the expert panel agreed on the following (1) same-day discharge after POEM can be considered in select patients; (2) a single dose of prophylactic antibiotics may be as effective as a short course; (3) a modified diet can be advanced as tolerated; and (4) all patients should be followed in clinic and undergo objective testing for surveillance and management of reflux. Consensus could not be achieved on the indication of post-POEM esophagram to evaluate for leak. CONCLUSIONS: The results of this Delphi process established expert agreement on several important issues and provides practical guidance on key aspects in the care of patients following POEM.
