Abstract
Chronic obstructive pulmonary disease (COPD) affects >15 million individuals in the United States and is a common comorbidity in patients undergoing surgery; therefore, the association between COPD in patients and postoperative surgical outcomes was investigated. The objective of this study was to assess the associations between COPD and postoperative morbidity, mortality, and hospital duration of stay. Patients who underwent cholecystectomy, appendectomy, small bowel resection, partial colectomy, hepatic resection, gastrectomy, pancreatectomy, and ventral hernia repair with and without COPD (n = 331,425) in the National Surgical Quality Improvement Program database from 2007 to 2010 were studied. The primary outcomes were 30-day morbidity, mortality, and hospital duration of stay; secondary outcomes were specific postoperative complications. COPD was present in 12,491 patients (3.8%) undergoing the abdominal operations surveyed. The 30-day morbidity and mortality rates and hospital duration of stay for patients undergoing all abdominal procedures reviewed was greater for patients with COPD compared with patients without COPD (all P < .0001, except hepatic resection). Multivariate analysis controlling for comorbidities revealed that COPD was associated independently with increased postoperative morbidity in all abdominal procedures reviewed, increased postoperative mortality after cholecystectomy, appendectomy, small bowel resection, and ventral hernia repair, and increased duration of stay after cholecystectomy, small bowel resection, partial colectomy, gastrectomy, pancreatectomy, and ventral hernia repair (all P < .05). Patients with COPD undergoing operative procedures in the abdomen have increased morbidity, mortality, and duration of stay. This study highlights the importance of studying potential preoperative optimization of pulmonary status in patients with COPD before operation.
