| Research Abstract |
[Introduction]Open surgery for advanced esophageal cancer with lymph node dissection is one of several invasive surgeries in digestive tract. As an application of minimally invasive surgery to advanced esophageal cancer the authors introduced totally endoscopic surgery for advanced esophageal cancer utilizing HALS technique.
[Procedure]At the first step we keep the patient in lithotomy position. Stomach is mobilized by using HALS technique. Mobilized stomach is pulled up to cervical area through retrosternal route. Gastric tube is anastomozed with cervical esophagus. At the second step, the patient's position changes to left lateral. Then, thoracoscopic esophagectomy with mediastinal lymph node dissection is carried out.[Clinical results]So far, eight patients received this surgery. In three patients surgery was converted to open approach, because of severe adhesion of pleura or chronic cholecystitis. In five cases this surgery was accomplished. In those cases postsurgical evaluation of %VC recovered rapidly. Patients discharged hospital in a relatively short period. We experienced no major complications and all the patient recovered well.[Conclusion]The results of this pilot study were not so bad. Therefore, we can keep this study for a while.
