Perioperative real-time monitoring of indocyanine green (ICG) video-blood perfusion and thermograpy of gastric tube during esophageal reconstruction

摘要

The blood supply of gastric tube is one of the reasons of the leakage of anastomosis between esophagus and gastric tube. ICG intraoperative angiography reveals the blood flow of gastric tube in comparison with thermography more clearly.The leakage of anastomosis in the esophageal surgery sometimes becomes a fatal complication.One major reason of the leakage of anastomosis between esophagus and gastric tube is blood supply and drainage of gastric tube.We would like to know the blood flow in the anastomosis area in the operation.Recently, intraoperative indocyanine green angiography was used to evaluate the viability of skin, flap tissue in plastic surgery and graft patency in coronary bypass.The purpose of this study is to evaluate a new intraoperative angiography technique and classical method.
