Background: Anastomotic leakage (AL) is a dreaded complication after oesophagectomy. Endoluminal vacuum-assisted closure therapy (EVAC) has been increasingly used as a first-line treatment for AL. We aimed to identify any potential adverse effects of a neoadjuvant therapy (chemotherapy (CT) or radiochemotherapy (RCT)) on EVAC.
Methods: We performed a retrospective cohort study at our tertiary centre between 2013 and 2024. All patients who underwent EVAC for AL after oesophagectomy were included in this study. Parameters such as success rate, length of therapy, number of sponges needed, changes in treatment, and survival were analysed.
Results: A total of 29 patients were included, 19 of whom received CT/RCT and 10 of whom received no neoadjuvant treatment (NT). There was no significant difference in patient survival (30-day survival rate CT/RCT n = 1 (5.3%) vs. NT n = 1 (10%), p = 0.632), success rate (CT/RCT n = 15 (78.9%) vs. NT n = 9 (90%), p = 0.454), and length of therapy (CT/RCT vs. NT 24.11 vs. 23.8, p = 0.681), the number of sponges required (CT/RCT vs. NT 6.26 vs. 6.6, p = 0.835), and the need for changing treatment (CT/RCT n = 5 (26.3%) vs. NT n = 1 (10%), p = 0.303).
Conclusions: NT did not affect the success rate or length of therapy. Thus, we found no significant influence of CT/RCT on EVAC for AL after oesophagectomy.
