Abstract:
Objective: To investigate the safety and feasibility of Da Vinci robot-assisted pylorus and vagus nerve-preserving partial gastrectomy for gastric cancer. Methods: In this study, descriptive case series method was used to retrospectively analyze the data of 3 patients with gastric cancer who underwent Da Vinci robot-assisted pylorus and vagus nerve-preserving partial gastrectomy in the First Affiliated Hospital of Dalian Medical University from December 2020 to February 2021. The linear layout was adopted for the setting of trocar, and the co-axial direction was the line connecting the umbilicus and splenic hilum. The inferior pyloric arteries and veins need to be preserved. The center was the bifurcation of the right gastroepiploic vessel and the inferior pyloric vessel. Dissection and exposure were performed from the upper, lower, right and left sides, and ventral and dorsal sides to complete the dissection of the inferior pyloric lymph nodes. The superior border of the pancreas was treated by the right diaphragmatic crus approach, the left retroperitoneal approach and the esophageal approach to determine the distribution of the posterior vagal trunk and its branches, and to determine the anatomical relationship with the left gastric artery. The left gastric artery was cut off while the celiac branch of vagus nerve and cardia branch of left gastric artery were preserved. Lymph node dissection was performed on the lateral side of nerve fibers around the blood vessels. Result: All the 3 patients successfully completed the robotic surgery without conversion to laparoscopy or laparotomy. The operation time was (340.0±26.4) (300-390) minutes, the intraoperative blood loss was (13.3±3.3) (10-20) ml, the number of dissected lymph nodes was 26.7±3.9 (19-32), the length of pylorus canal preserved was (3.3±0.3) (3-4) cm, the distal margin was (2.3±0.3) (2-3) cm, and the proximal margin was (3.0±0.6) (2-4) cm. No postoperative complications occurred in all the 3 patients. The first flatus time was 2-3 days after operation, and the postoperative hospital stay was 6-7 days. The operation cost of the 3 patients was (40±7) (33-53) thousand yuan. Conclusion: Da Vinci robot-assisted pylorus and vagus nerve-preserving partial gastrectomy is safe and feasible.
