Background In curative surgery for esophageal cancer a gastric conduit is often used to replace the resected esophagus. Anastomotic leakage (AL) is a serious complication. Sufficient perfusion in the gastric conduit is critical for the anastomosis. The aim of this pilot study was to investigate the feasibility of intraoperative indocyanine green (ICG) and near-infrared fluorescent imaging as a tool to assess perfusion of the gastric conduit in order to prevent postoperative AL. Methods Patients undergoing esophageal resection at Umeå University Hospital were invited to participate in this prospective study during 2017–2022. The surgery performed was open Ivor-Lewis esophagectomy. ICG was administered intraoperatively and video footage of the near-infrared fluorescence was recorded. The time from injection until visualized fluorescence in the gastric conduit was measured, as well as the intensity of the fluorescence in the gastric conduit. A loop of jejunum was used as control and the quotient between the measurement in the jejunal loop and in the gastric conduit was used for objective assessment. Results 50 individuals were included. 46 patients had received neoadjuvant chemoradiotherapy and 3 had received chemotherapy only. 32 patients had video footages that were possible to assess as described above. Of these 11 had AL. No differences were demonstrated between patients with AL and those without, neither regarding time to fluorescence (p = 0.42), nor intensity (p = 0.72). Conclusion AL is a serious complication to esophageal surgery with a high incidence. Perfusion assessment of the gastric conduit using ICG has emerged as a promising technique to reduce AL. In this pilot study we developed two techniques to evaluate the perfusion in an objective manner, whilst none of these seem to be able to predict postoperative AL. [ABSTRACT FROM AUTHOR] |
