Initial Experience with Robotic Gastrectomy in Patients with Gastric Cancer: An Assessment of Short-Term Surgical Outcomes.

Abstract

Robotic gastrectomy (RG) is an alternative minimally invasive surgical technique that has gradually come into use for the treatment of gastric cancer (GC). This study aimed to assess the feasibility and safety of RG for the treatment of GC. We retrospectively reviewed the use of RG in 47 patients with GC, and clinicopathological features and surgical outcomes were evaluated. The median age and body mass index of the patients were 68 years and 21.9 kg/m2, respectively. Distal gastrectomy, total gastrectomy, and proximal gastrectomy were performed in 39 (83.0%), 5 (10.6%), and 3 (6.4%) patients, respectively. The median operative time was 354 (256- 603) min. None of the operations were converted to open or laparoscopic procedures. The median blood loss was 15 (2-350) ml. None of the patients required blood transfusion. The mean number of resected lymph nodes was 43 (7-93). The median duration of postoperative hospital stay was 13 (9-37) days. Approximately 4.3% and 2.1% of the patients had anastomotic leakage and pancreatic fistula, respectively. One (2.1%) patient had Clavien-Dindo classification grade IIIa surgical complication (anastomotic leakage). No treatment-related deaths were observed. These findings suggest that RG might be a safe and feasible procedure for the treatment of GC.
