Although the association between acute pancreatitis and pleuropulmonary damage is well documented, so far no information on lung function in patients with chronic pancreatitis is available. In this study functional, radiological, and clinical investigations have been carried out in 42 patients affected by chronic calcific pancreatitis (CCP) and in 50 controls in a case-control study. An impairment of pulmonary diffusing capacity has been detected in CCP patients, while all the parameters of ventilatory function were not different from controls. This finding suggests the presence of early lung parenchymal damage in chronic pancreatitis secondary to either emphysema or pulmonary fibrosis.
