Efficacy and safety of robotic spine surgery: systematic review and meta-analysis.

BACKGROUND: Robotic surgery (RS) may offer benefits compared with freehand/conventional surgery (FS) in the treatment of patients with spinal disease. The aim of this study was to evaluate the efficacy and safety of RS versus FS in spinal fusion. METHODS: A systematic review and meta-analysis was performed. Data analysis and risk of bias assessment were analysed using REVMAN V5.3. RESULTS: We found 11 randomised clinical trials involving 817 patients (FS: 408, RS: 409). The main diagnosis was degenerative spine disease. SpineAssist, Renaissance (Mazor Robotics), Tianji Robot and TiRobot robots (TINAVI Medical Technologies) were used. Pedicle screw placement within the safety zone (grades A + B according to the Gertzbein and Robbins scale) ranged from 93% to 100% in FS versus 85-100% in RS (relative risk 1.01, 95% CI 1.00-1.03, p = 0.14). Regarding intervention time, the meta-analysis showed a mean difference (MD) of 6.45 min (95% CI -13.59 to 26.49, p = 0.53). Mean hospital stay was MD of -0.36 days (95% CI -1.03 to 0.31, p = 0.30) with no differences between groups. Contradictory results were found regarding fluoroscopy time, although there seems to be a lower radiation dose in RS versus FS (p < 0.05). Regarding safety, the studies included surgical revision frequency. CONCLUSIONS: No conclusive results were found suggesting that there are benefits in using RS over FS for spinal fusion. Further research with adequate patient selection, robot type and quality-of-life variables is needed. LEVEL OF EVIDENCE: level 1.

Detection of the Frail Elderly at Risk of Postoperative Sepsis.

With the increase in the elderly population, surgery in aged patients is seeing an exponential increase. In this population, sepsis is a major concern for perioperative care, especially in older and frail patients. We aim to investigate the incidence of sepsis in elderly patients receiving diverse types of surgical procedures and explore the predictive capacity of the Hospital Frailty Risk Score (HFRS) to identify patients at high risk of incidence of postoperative sepsis. This study relies on information from the Spanish Minimum Basic Data Set, including data from nearly 300 hospitals in Spain. We extracted records of 254,836 patients aged 76 years and older who underwent a series of surgical interventions within three consecutive years (2016-2018). The HFRS and Elixhauser comorbidity index were computed to determine the independent effect on the incidence of sepsis. Overall, the incidence of postoperative sepsis was 2645 (1.04%). The higher risk of sepsis was in major stomach, esophageal, and duodenal (7.62%), followed by major intestinal procedures (5.65%). Frail patients are at high risk of sepsis. HFRS demonstrated a high predictive capacity to identify patients with a risk of postoperative sepsis and can be a valid instrument for risk stratification and vigilant perioperative monitoring for the early identification of patients at high risk of sepsis.
