Association of Preoperative Inspiratory Muscle Weakness and Respiratory Sarcopenia with Postoperative Pneumonia Following Esophagectomy: A Multicenter Retrospective Cohort Study

Key Points

• To explore the relationship between preoperative inspiratory muscle weakness and respiratory sarcopenia with the incidence of postoperative pneumonia following esophagectomy.
• Retrospective cohort design
• Multicenter data collection
• Assessment of inspiratory muscle strength and respiratory sarcopenia
• Analysis of pneumonia incidence post-esophagectomy
• Preoperative inspiratory muscle weakness significantly increases the risk of postoperative pneumonia.
• A potential association between respiratory sarcopenia and pneumonia was observed, but remains unclear.
• Further investigation is needed to clarify the roles of these factors.
