title: Laparoscopic versus open cholecystectomy: effect on pulmonary function tests.
abstract: OBJECTIVE
  Operations often cause impairment in respiration due to pain. This study was designed to compare the changes in pulmonary function tests after open and laparoscopic cholecystectomy.
  
  
  METHODS
  Two groups of 35 patients were randomly set up. Each patient had 3 pulmonary function tests performed and 2 postero-anterior grid chest roentgenograms taken. All of these data were evaluated by the same group of investigators.
  
  
  RESULTS
  After taking into consideration the difference between pulmonary function tests, values were not significant (P < or = 0.05). All pulmonary function test values decreased significantly on the 1st postoperative day (P < or = 0.05). When postero-anterior chest roentgenograms were compared no clinically evident atelectasis except 3 lineary was seen in the laparoscopic cholecystectomy group, whereas 5 lineary, 7 focal, and 3 segmentary atelectasia were encountered in the open cholecystectomy group (P < or = 0.05).
  
  
  CONCLUSIONS
  We believe that laparoscopic cholecystectomy has more advantages when speaking of postoperative pulmonary function tests and atelectasia.
