Core Tip
Core Tip: The robotic surgery system is widely used in the surgical field. Pylorus and vagus nerve-preserving gastrectomy is a function-preserving surgery for early gastric cancer (GC). We introduced an robot-assisted pylorus and vagus nerve-preserving gastrectomy-based operative procedure and technical points as well as report the initial experience. We analyzed the the mean operative time, mean blood loss, mean number of lymph nodes harvested, length of preserved pylorus canal, distal margin, proximal margin, and postoperative complications of 8 patients with early GC. None of the cases required conversion to laparotomy. The main postoperative complications were hyperamylasemia and gastric stasis. These study results are preliminary, and on establishing a standard surgical treatment, large-sample, multi-center, and prospective clinical trial should be conducted.
