Abstract
Objective
To investigate the association between preoperative and postoperative sleep disorders and postoperative complications in elderly patients undergoing radical gastrectomy for gastric cancer.
Methods: A retrospective analysis was conducted on the clinical data of 485 elderly patients who underwent gastric cancer surgery in our hospital from May 2020 to May 2023. Patients were categorized into groups based on the occurrence of postoperative complications within 30 days after surgery: no complications, mild complications, and severe complications. Clinical data of patients in different groups were compared and analyzed.
Results: A total of 485 gastric cancer patients were included in this study, among whom 325 patients had no postoperative complications, accounting for 67.01%; 139 patients had mild complications, accounting for 28.66%; and 21 patients had severe complications, accounting for 4.33%. Comparison of Pittsburgh Sleep Quality Index (PSQI) scores (preoperative and postoperative) among the three groups showed statistically significant differences (P < 0.05). Compared with the group with no complications, patients in the severe complications group and mild complications group had significantly higher PSQI scores (P < 0.05). Ordered logistic regression analysis revealed that preoperative and postoperative PSQI scores were factors influencing the occurrence of postoperative complications in elderly patients undergoing radical gastrectomy for gastric cancer (P < 0.05). A higher preoperative PSQI score was associated with an increased risk of postoperative complications, and similarly, a higher postoperative PSQI score was associated with an increased risk of postoperative complications. Spearman correlation analysis results showed a positive correlation between preoperative PSQI score and postoperative complication severity, as well as between postoperative PSQI score and postoperative complication severity in elderly gastric cancer patients.
Conclusion: Preoperative and postoperative sleep disorders are closely associated with postoperative complications in elderly patients undergoing radical gastrectomy for gastric cancer. Higher preoperative and postoperative PSQI scores indicate an increased risk of postoperative complications.
