Primary esophageal cancer treated by esophagectomy with distal pancreatectomy: a report of three cases.

Esophagectomy and pancreatectomy are recognized as highly invasive procedures with relatively high complication rates; therefore, careful indication decisions are required. The depth of tumors invading adjacent organs, such as the aorta, vertebral body, and trachea, is defined as T4, and are estimated to have a low survival rate even after treatment. Conversely, pancreatic invasion of esophageal cancer is uncommon and not clearly defined as T4. Thus, it is often difficult to decide on a treatment strategy for locally advanced esophageal cancer. In this study, we describe three cases of esophagectomy with combined resection of the pancreas and spleen for esophageal cancer or esophagogastric junction cancer with invasion of the pancreatic body or tail. To the best of our knowledge, this is the first report of esophagectomy and combined resection of the pancreas and spleen in multiple patients from a single institution.
