  • Title: Postoperative pulmonary changes after laparoscopic cholecystectomy.
    Author: Torrington KG, Bilello JF, Hopkins TK, Hall EA.
    Journal: South Med J; 1996 Jul; 89(7):675-8. PubMed ID: 8685752.
    Abstract:
    Laparoscopic cholecystectomy (LC) has been widely used in recent years because of short postoperative hospital stays and low morbidity. In this study, 24 patients were prospectively evaluated with preoperative and postoperative spirometry, arterial blood gas determinations, and chest radiographs to quantitate the magnitude of postoperative pulmonary changes after LC. Statistically significant reductions were noted in forced vital capacity (FVC) (mean decrease, 810 mL) and forced expired volume in 1 second (FEV1) (mean decrease, 420 mL). Clinically important changes in arterial blood gas values did not occur. Of 20 postoperative chest films, 7 showed the development of atelectasis or effusion and 9 showed persistence of subdiaphragmatic free air 24 hours after LC. In summary, LC caused mean decreases of 23% in FVC and 16% in FEV1 24 hours after surgery. The physiologic derangements that follow LC are sufficiently small that all but the most severely impaired patients with pulmonary disease should be able to tolerate this operation.
