Table 2 Synopsis of endoscopic vacuum therapy (EVT) data

From: Management of esophageal perforations in infants by endoscopic vacuum therapy: a single center case series

Infant no. Initial size of perforation Begin EVT (days after first diagnosis of esophageal perforation/leakage) EVT system (film/sponge) No. of EVT film/sponge exchanges Duration of EVT (days) Additional endoscopic therapy / EVT features Initial EVT pressure (mmHg) Initial EVT pressure intensity EVT settings during ongoing EVT Successful closure at the end of EVT Adverse events Outcome
1 3 mm 17 EVT film, later sponge 12 39 First EVT placement was fluoroscopically by wire guidance −75 Low −150 mmHg, high intensity Yes None Alive until follow-up, no recurrence of defect
2 2/3 of circumference of anastomosis 2 EVT film, later sponge 7 32 Balloon dilation (increasing from 4 to 10 mm) of anastomosis prior to EVT insertion (on EVT initiation and for first 4 EVT exchanges) −75 Low −125 mmHg, medium intensity Yes Stenosis of anastomosis Alive until follow-up, no recurrence of defect
3 6 cm 0 EVT film 1 7 None −100 Medium Unchanged Yes Gastric ulcer Alive until follow-up, no recurrence of defect
4 4 cm 0 EVT film 2 11 None −100 Medium Unchanged Yes None Alive until follow-up, no recurrence of defect
