Esophagectomy, followed by esophageal replacement using gastric/colonic conduits, is a complex surgical procedure with significant perioperative morbidity. The most significant and potentially life-threatening complication associated with esophageal replacement is conduit ischaemia, resulting in anastomotic leak and conduit necrosis. Ensuring adequate perfusion of the conduit remains the key to preventing conduit ischaemia. Indocyanine green (ICG) enhanced near-infrared fluorescence imaging is a novel technique which has been used for assessing bowel perfusion. While numerous studies have focused on ICG fluorescence imaging for assessment of gastric conduit perfusion after esophagectomy, data regarding its use for colonic conduits is limited to case reports. ICG fluorescence imaging can help in resolving intraoperative issues by predicting the adequacy of colonic conduit perfusion, thereby preventing postoperative morbidity. To the best of our knowledge, this is the first report in Indian literature describing the utility of ICG fluorescence imaging for assessment of perfusion of colonic interposition.
