Results

Complete closure of the defect (median defect size 29.0 mm) was successfully achieved in 24 cases (80%). Delayed bleeding occurred in one case with incomplete closure (3.3%). The median ELOC procedure time was 25.5 minutes (interquartile range, 20.0 to 30.0 minutes). The sustained closure rates were 83.3% (20/24) on POD 3 in the 24 cases with complete closure.
