Abstract

Background: Esophagectomy with reconstruction using a gastric conduit is associated with a relatively high rate of anastomotic leakage. We used indocyanine green tissue angiography to evaluate the gastric conduit intraoperatively before gastroesophageal anastomosis to identify ischemia. Methods: We performed an institutional review board-approved retrospective review of all esophagectomies performed from 2010 to the beginning of 2011. Patient histories and perioperative outcomes were reviewed retrospectively. Postoperative morbidity and 30-day mortality were determined. Results: Eleven patients had an esophagectomy performed using this technology. All had adequate perfusion on gross examination. All but 1 had good perfusion with tissue angiography, and there were 2 anastomotic leakages leaks including this patient. There were no mortalities at 30 days. Conclusions: We report preliminary results using this imaging system in esophageal reconstructive surgery. Larger randomized controlled studies are needed to determine if surgical outcomes can be improved using this technology. © 2013 Elsevier Inc. All rights reserved.
