Efficacy and prognostic analysis of carbon nanotracers combined with the da Vinci robot in the treatment of esophageal cancer

Figure 1  Schematic diagram of the visualization process using the nanocarbon lymph node tracer.

Figure 2 Comparison between the observation and control groups. A: Operation time; B: Recurrent laryngeal nerve lymph node dissection time; C: Intraoperative blood loss; D: Number of dissected lymph nodes. ^aP < 0.05, indicates statistically significant difference between the two groups; ^bP < 0.01, indicates statistically significant difference between the two groups.

Figure 3 Comparison between the observation and control groups. A: C-reactive protein (CRP); B: Cortisol; C: Adrenaline levels. ^aP < 0.05; ^bP < 0.01; ^cP < 0.001. E: Epinephrine.

Figure 4 Comparison between the observation and control groups in pre- and postoperative results. A: Interleukin (IL)-6; B: IL-10; C: Tumor necrosis factor-alpha levels (TNF-a). ^aP < 0.05; ^bP < 0.01.

Figure 5 Comparison between the observation and control groups. A: Occurrence of complications; B: Patient prognosis. ^aP < 0.05; ^bP < 0.01.
