Pdf Summary

This study aimed to investigate the relationship between postoperative anemia and postoperative outcomes after robotic-assisted pulmonary lobectomy (RAPL). Anemia is characterized by a deficiency in red blood cells that carry oxygen to the body's tissues. The retrospective analysis included 729 patients who underwent RAPL by one surgeon between September 2010 and August 2022.<br /><br />The patients were divided into an Anemic group and a Non-Anemic group based on their postoperative hematocrit levels. The study analyzed demographics, rates of complications, and outcomes using various statistical tests.<br /><br />The results showed that anemic patients had higher estimated blood loss compared to non-anemic patients. However, the rates of intraoperative complications were similar between the two groups. Postoperatively, anemic patients had higher incidences of prolonged air leaks (5 days or longer), longer chest tube duration, and longer hospital length of stay compared to non-anemic patients.<br /><br />The study found that thirty-day mortality did not significantly differ between the anemic and non-anemic groups. Additionally, the median overall survival did not differ significantly between the two groups.<br /><br />In conclusion, anemic patients had higher incidences of certain postoperative complications and longer hospital stays compared to non-anemic patients. However, their overall survival was similar. These findings suggest that postoperative anemia may be a risk factor for specific complications after robotic-assisted pulmonary lobectomy.<br /><br />References:<br /><br />1.
