Summary
Brief summary (as posted)
A staging system was defined based on morphological extent of disease (stage I to stage IV for primary disease, and stage R for recurrent disease). Specific surgical technique was used for each stage. Demographics, perioperative data, short-term and long-term outcomes were evaluated according to the disease stage.
