Gastric Tube Reconstruction with Superdrainage Using Indocyanine Green Fluorescence During Esophagectomy.

We report a case of gastric tube reconstruction with superdrainage using indocyanine green fluorescence during esophagectomy for esophageal cancer. A 53-year-old man with a history of early esophageal cancer treated with endoscopic mucosal dissection experienced esophageal cancer recurrence. There was no evidence of lymph node involvement or distant metastasis on computed tomography; therefore, we performed thoracoscopic esophagectomy. After thoracoscopic esophagectomy, we created a gastric tube. When pulling up the gastric tube through the post-mediastinum route, a root of the right gastroepiploic vein was injured. We subsequently performed superdrainage to avoid congestion of the gastric tube with omental vein and pre-tracheal vein anastomosis at the neck, and confirmed venous flow using the indocyanine green fluorescence method. No postoperative anastomotic leakage was observed, and the patient was discharged 22 days after surgery. Thus, we recommend the indocyanine green fluorescence method in cases involving superdrainage during esophagectomy.
