Safety and feasibility of same-day discharge for per-oral endoscopic myotomy.

Aims: Per-oral endoscopic myotomy (POEM) is a recognised treatment for achalasia, with the accepted approach involving admission for imaging and dietary progression. However, recent publications suggest same-day discharge (SDD) may be possible, which could be time and cost-saving. We sought to investigate the safety of SDD following POEM.

Methods: Fifty consecutive POEMs at two referral centres in New Zealand were performed between 2020-2023. All patients were planned for early dietary introduction and were eligible for SDD if symptoms were managed. Analgesia was available in recovery and supplied at discharge. Imaging and endoscopy were performed only if there were clinical concerns. Rates of discharge clearance, discharge, complications and re-admission were analysed.

Results: All 50 POEMs were technically successful. A total of 41/50 (82%) received clearance for SDD. Additionally, 35/50 (70%) achieved discharge and 6/50 (12%) were observed overnight for social reasons, including lack of transport to the referring domicile. Of the patients not cleared for SDD, 7/9 (78%) were discharged within 24 hours, and the others after 48 and 72 hours. Procedural complications were recorded in three patients (6%), with one requiring endoscopic assessment and clipping. There were two re-admissions (4%), both lt;24-hour hospital stays, and managed medically.

Conclusions: The majority of patients achieved same-day discharge clearance (82%) and 96% required less than 24 hours hospital stay. Complication and re-admission rates were low overall. We have demonstrated that POEM can be an SDD procedure facilitated by early dietary introduction and liberal analgesia, without the need for routine imaging or endoscopy.
