Same-day discharge is safe and feasible following POEM surgery for esophageal motility disorders

Introduction Per-oral endoscopic myotomy (POEM) is an effective treatment for achalasia and other esophageal dysmotility disorders. Current practices surrounding post-operative care involve admission and routine esophagogram prior to discharge. This study aims to establish the safety and feasibility of same-day discharge following POEM. Methods Retrospective analysis of prospectively collected data for patients who underwent POEM between November 2013 and June 2019 at a single institution in Ontario, Canada. Patients were discharged home on the same day with controlled pain, when tolerating clear fluids. Patients were admitted if clinically indicated. Esophagography was initially a systematic practice prior to discharge, but later only performed when clinically indicated. Emergency department visits and hospital admissions within 90 days were assessed. Results In total, 90 patients underwent a successful POEM procedure. A total of 72 patients (79.1%) were discharged on the same day, 14 patients (15.4%) were discharged home the following day, and 5 patients (5.5%) experienced longer admissions to hospital. One POEM was unsuccessful. 22 (24.2%) patients had adverse events, leading to 8 (8.8%) unplanned admissions, with one patient requiring prolonged admission for esophageal leak, identified clinically. Fifty-three patients underwent routine esophagography while part of our protocol, with no identified leak, which prompted our change in practice to only perform esophagography when clinically indicated. In the 90-day post-procedure, ten patients visited the emergency department, of which seven were re-admitted, five for POEM-related issues. Our mean Eckhardt score at 2 weeks was 2.1 from 7.2 preoperatively. Conclusion This study establishes that same-day discharge is both safe and feasible following POEM and suggests that esophagography should be performed only when clinically indicated. This represents a shift from the routine practice of admission and imaging for patients undergoing POEM, encouraging the transition to outpatient POEM procedures.
