Evaluation of Fibrin Sealant in Prevention of Cervical Anastomotic Leakage After McKeown Esophagectomy: A Single-Center, Retrospective Study.

Background: Anastomotic leakage remains an issue after esophagectomy for patients with esophageal or esophagogastric junction cancer. Previous studies have indicated that the intraoperative application of fibrin sealant may reduce the incidence of postoperative anastomotic leakage. This retrospective study was aimed to evaluate the efficacy and safety of fibrin sealant in the prevention of anastomotic leakage in patients undergoing McKeown esophagectomy.

Methods: We designed a single-center, retrospective study. Between January 2018 and December 2019, 227 patients with esophageal or esophagogastric junction cancer undergoing McKeown esophagectomy performed by our team were retrospectively identified, of whom 86 patients were included in the FS group and 141 patients were included in the control group. Intraoperatively, 2.5 ml of porcine fibrin sealant was applied circumferentially to the cervical anastomosis after the anastomosis was created in the FS group. The primary outcome was the incidence of cervical anastomotic leakage within the first three months after surgery.

Results: The differences in baseline clinical characteristics between the two groups were not significant except for a history of drinking. In the FS group, the postoperative cervical anastomotic leakage rate was lower (FS group: 4.7% [4 of 82] vs. control group: 19.9% [28 of 141], p < 0.01). Multivariate logistic regression showed that the intraoperative application of fibrin sealant was an independent protective factor for anastomotic leakage (OR 0.169, 95% CI 0.055-0.515, p = 0.002).

Conclusions: The intraoperative application of fibrin sealant could possibly prevent cervical anastomotic leakage after McKeown esophagectomy with satisfactory safety. Further prospective clinical trials are warranted.
