Background/Aim:
The aim of this study was to determine the association between post-esophagectomy pneumonia and the presence of pathogenic organisms in the sputum or pharynx and postoperative systemic inflammatory response syndrome (SIRS).
Materials And Methods:
This retrospective study included 98 patients diagnosed with esophageal cancer who had undergone esophagectomy.
Results:
Postoperative pneumonia was observed in 24 patients (24.5%). Of the total 98 patients, 45 (45.9%) were tested positive for pathogenic organisms preoperatively, and 16 of those (35.6%) developed postoperative pneumonia; postoperative pneumonia occurred at a higher rate in these patients compared to pathogenic organism-negative patients (p=0.019). Postoperative SIRS was observed in 62 patients (63.3%), and 21 of these (33.9%) developed postoperative pneumonia, a significantly higher rate compared to patients without SIRS (p=0.007).
Conclusion:
Postoperative pneumonia was significantly associated with the presence of pathogenic organisms in the sputum or pharynx and postoperative SIRS.

Inflammatory Response
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
