Sa1269 LATERAL EXTENSION OF ESOPHAGOGASTRIC CANCER UNDER THE SQUAMOUS EPITHELIUM

Abstract

All-cause readmission rates were 3.7% (NZ17) for POEM and 4.6% (NZ125) for LHM (pZ0.469). There was no difference in the odds ratio for readmission after POEM versus LHM (ORZ1.29, CI:0.77-2.17). Mean hospitalization charges for readmissions in the LHM group were significantly higher than the POEM group ($68547 vs. $27773, p<0.001). The length of stay for readmitted patients after LHM was also significantly higher than POEM (5.2 days vs. 2.8 days, p<0.001). There was no inpatient mortality for either group for readmission. Conclusions: Outcomes from our large database suggest that in real-world practice, POEM is the preferred treatment for patients who are frail, older, and have more comorbidities. There was no difference in readmission rates between the two POEM and LHM. However, LHM patients had a longer length of stay and higher total hospitalization costs during the rehospitalization.
