Can postoperative pulmonary complications after elective cholecystectomy be predicted?

Area of Science:

• Thoracic Surgery
• Pulmonary Medicine
• Health Services Research

Background:

• Postoperative pulmonary complications are a significant concern in elective cholecystectomy.
• Predicting these complications and prolonged hospitalization is crucial for patient management and resource allocation.

Purpose of the Study:

• To identify predictors of postoperative morbidity, specifically pulmonary complications and length of hospital stay, in patients undergoing elective cholecystectomy.
• To evaluate the cost-effectiveness of using preoperative pulmonary function testing for respiratory therapy services.

Main Methods:

• Prospective examination of 209 patients undergoing elective cholecystectomy.
• Assessment of various factors including age, sex, smoking history, respiratory history, obesity, incision type, and preoperative pulmonary function tests (spirometry, single-breath nitrogen test).
• Statistical analysis using analysis of variance, discriminant analysis, and chi-square tests.

Main Results:

• A total of 31 pulmonary complications (14.8%) were identified, including atelectasis, purulent bronchitis, and pneumonia.
• Patients with complications averaged 1.5 days longer hospitalization.
• Abnormal spirometry (MEFV) and single-breath nitrogen test (SBN2) significantly predicted pulmonary complications (p < 0.001).
• Reduced preoperative forced vital capacity (FVC) predicted prolonged hospitalization (p < 0.001).
• Active smoking and respiratory disease history correlated with abnormal small airway function but did not predict morbidity.

Conclusions:

• Preoperative pulmonary function tests, particularly spirometry and SBN2, are significant predictors of postoperative pulmonary complications.
• Reduced FVC is a predictor of prolonged hospitalization.
• Current pulmonary function tests lack the specificity to enhance the cost-effectiveness of postoperative respiratory therapy services.
