Introduction
Advantages of robotic approach for proximal gastric cancer (GC) still remain to be clarified. The aim of this study is to investigate the safety, feasibility and advantages of robotic approach for surgical treatment of proximal GC.
Patients and Methods
Among 144 cases of robotic gastrectomy (RG) in our institutions from 2012 to 2020, we excluded patients who required lower mediastinal lymphadenectomy for esophagogastric junction cancer (two cases) and who underwent distal gastrectomy for distal GC (103 cases). Then thirty-two robotic total gastrectomy (RTG) and 7 proximal gastrectomy (RPG) patients were analyzed. We retrospectively evaluated postoperative complications, amylase levels of drainage fluid (d-AMY), number of retrieved lymph nodes and postoperative hospital stay, using our prospectively maintained database.
Results
There were two (5.1%) postoperative complications of Clavien-Dindo classification Grade 3 (pancreatic fistula and ileus). The median level of d-AMY was 391 IU/L. The average of lymph node retrieval numbers was 52. The median post-operative hospital stay was 13 days. There was no severe anastomotic complication in this cohort.
Conclusion
Robotic surgery for proximal gastric cancer was considered safe and feasible. The results of sufficient retrieval number of lymph nodes and low d-AMY level suggested that sufficient lymphadenectomy with oncologic and surgical safety could be achieved, as well as safe reconstruction, by using robotic approach.
