Core Tip

Core tip: Endoscopic trans-esophageal submucosal tunneling surgery (EESTS) technique is a new branch of endoscopic tunneling technology for diagnosing and treating diseases located around the aorta ventralis. The objective of our study was to simulate surgeries in a porcine model and to assess the efficiency of this new strategy. The surgeries included celiac trunk ganglion neurolysis, partial hepatectomy and splenectomy, partial tissue resection in the area of the posterior peritoneum, and endoscopic submucosal dissection combined with lymph node dissection. And we confirmed that EESTS is a feasible and safe technique.
