Venous Supercharging Relieves Venous Congestion and Salvages Gastric Conduit Post-esophagectomy

The purpose of this study was to evaluate the effectiveness of incorporating additional venous anastomoses (venous super charging) in improving gastric conduit congestion and preventing complications such as conduit loss and anastomotic leakage following esophagectomy. We included two consecutive patients, one undergoing esophagectomy and the other undergoing laryngo-pharyngo-esophagectomy. Additional venous anastomoses were performed to alleviate venous congestion at the oral end of the gastric conduit. The perfusion assessment of the anastomosis was evaluated using indocyanine green fluorescence angiography (ICG FA) by Stryker's SPY PHI device. Both patients experienced anastomotic leakage, with one having a grade 2 leak and the other a grade 1 leak. Fortunately, conservative measures proved successful in managing these complications and there was no conduit loss. The incorporation of additional venous anastomoses effectively relieves venous congestion in the gastric conduit after esophagectomy and prevent conduit loss, indicating its potential in improving patient outcomes.
