Pulse Oximetry for Assessment of Gastric Tube Circulation in Esophageal Replacement After Subtotal Esophagectomy
Due to its simplicity, the stomach is widely used as a substitute following an esophageal resection, particularly in malignant diseases. In cancer patients, the smaller curvature of the stomach is resected, and the left gastric, gastroepiploic and the short gastric arteries are ligated to enhance surgical radicality and to achieve added length on the esophageal conduit . This technique demands extensive gastric mobilization using the Kocher manoeuver followed by an anastomosis in the neck between the esophageal remnant and the highest point of the gastric fundus. This, however, may compromise the circulation of the anastomotic area of the fundus and results in anastomotic leakage and stricture. Clinically, the fundic circulation may be difficult to assess since the fundus is vascularized only via a nonvisible submucosal plexus .
