Laparoscopic versus open cholecystectomy: effect on pulmonary function tests

Hepatogastroenterology. 2000 Mar-Apr;47(32):341-2.


Background/aims: 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.

Methodology: 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.
