ABSTRACT
OBJECTIVE: The efficacy of robotic surgery in oncological operations has been demonstrated, but its applicability in the elderly population (≥70 years) is limited in studies. This study aims to investigate the feasibility, safety, and short-term outcomes of robotic surgery in gastric cancer surgery in geriatric patients. PATIENTS AND METHODS: Patients who underwent robotic surgery for gastric cancer between July 2021 and September 2023 were included in the study. Patients were divided into two groups: the elderly group (≥70 years) and the younger group (<70 years). Demographic data, clinical findings, perioperative outcomes, and pathology results were analyzed and compared between the two groups. RESULTS: 63 patients were included in our study. Group 1, the younger patients (<70 years), consisted of 44 patients, while Group 2, the older patients (>70 years), consisted of 19 patients. The male gender was dominant in both groups (70.5% vs. 78.9%, p=0.486). ASA 2 was the most common score in both groups (70.5% vs. 52.6%, p=0.261). Group 2 had lower hemoglobin (11.3 vs. 10.1, p=0.017) and albumin levels (39.9 vs. 37.6, p=0.049). The average operation times were similar in both groups (255 min vs. 242 min, p=0.457). The median postoperative hospital stay was 5 days in both groups. The distributions of postoperative complications according to the Clavien-Dindo classification were similar. Postoperative 30-day mortality was observed in one patient in Group 2. The 90-day hospital readmission rates were similar (11.3% vs. 10.6%, p=0.459). The average tumor diameters were similar (38 mm vs. 48 mm, p=0.165), as were the numbers of dissected lymph nodes (35 vs. 34, p=0.796). According to pathology results, T4a tumors were most common in Group 1 and T0 tumors in Group 2 (34.1% vs. 31.6%, p=0.149). The most common lymph node involvements were N0 in Group 1 and N1 in Group 2 (36.4% vs. 36.8%, p=0.515). CONCLUSIONS: Robotic surgery in gastric cancer is considered a safe and feasible method in the elderly population due to its successful early outcomes, suggesting its reliability and effectiveness.
