Reconstruction of the Gastrointestinal Tract byHemi-DoubleStapling Method for the Esophagus andJejunum Using EEA OrVil in Laparoscopic Total Gastrectomy and Proximal Gastrectomy

Abstract

We report the method of anastomosis based on a hemi-double stapling technique (hereinafter, HDST) using a trans-oral anvil delivery system (EEA OrVil) for reconstructing the esophagus and lifted jejunum following laparoscopic total gastrectomy or proximal gastric resection. As a basic technique, end-to-side anastomosis was used for the cut-off stump of the esophagus and lifted jejunum. After the gastric lymph node dissection, the esophagus was cut off obliquely to the long axis using an automated stapler. EEA OrVil was orally, and a small hole was created at the tip of the obliquely cut-off stump with scissors to let the valve tip pass through. When it was confirmed that the automated stapler and center rod were made completely linear, the anvil and the main unit were connected with each other and firing was carried out. Then, HDST-based anastomosis was completed. The method may safe laparoscopic anastomosis between the esophagus and reconstructed intestine.
