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

Puntos clave

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.

Resumen

Preoperative IMW is a notable risk factor for postoperative pneumonia following esophagectomy. While a potential link with RS was found, its role remains uncertain and requires further investigation.
