Summary
Laparoscopic cholecystectomy showed better postoperative pulmonary function and less atelectasis compared to open surgery. Both procedures caused significant decreases in lung function on the first day after surgery.
Area of Science:
- Surgical Innovation
- Respiratory Physiology
- Minimally Invasive Surgery
Background:
- Surgical procedures, particularly abdominal operations, can lead to respiratory complications due to postoperative pain.
- Impaired respiratory function post-surgery can increase morbidity and prolong recovery.
Purpose of the Study:
- To compare the impact of open versus laparoscopic cholecystectomy on pulmonary function tests.
- To evaluate the incidence of postoperative atelectasis following these two surgical approaches.
Main Methods:
- Randomized study involving 70 patients divided into two groups: open cholecystectomy and laparoscopic cholecystectomy.
- Pulmonary function tests and chest roentgenograms were performed preoperatively and postoperatively.
- Data analysis was conducted by a blinded group of investigators.
Main Results:
- While overall pulmonary function test values did not significantly differ between groups (P < 0.05), both groups experienced significant decreases on postoperative day 1 (P < 0.05).
- Laparoscopic cholecystectomy group showed significantly lower rates of atelectasis (3 linear) compared to the open cholecystectomy group (5 linear, 7 focal, 3 segmental) (P < 0.05).
Conclusions:
- Laparoscopic cholecystectomy appears to offer advantages in preserving postoperative pulmonary function.
- Minimally invasive approaches like laparoscopy may reduce the risk of postoperative pulmonary complications such as atelectasis.
