Summary
Laparoscopic cholecystectomy (CL) causes fewer pulmonary complications like atelectasis and hypoxemia compared to open cholecystectomy (CO). CL patients showed significantly less reduction in pulmonary function post-surgery.
Area of Science:
- Medicine
- Surgery
- Pulmonology
Background:
- Pulmonary complications, including atelectasis and hypoxemia, are common after cholecystectomy.
- The choice between laparoscopic cholecystectomy (CL) and open cholecystectomy (CO) may influence postoperative pulmonary function.
Purpose of the Study:
- To compare the incidence of pulmonary atelectasis and hypoxemia between patients undergoing CL and CO.
- To evaluate the impact of surgical approach on pulmonary function after cholecystectomy.
Main Methods:
- A comparative study of 40 patients with gallstone disease, divided into CL and CO groups (20 patients each).
- Assessment of hypoxemia via PO2 measurements at multiple postoperative time points.
- Evaluation of atelectasis using preoperative and postoperative X-rays, categorized by severity.
Main Results:
- Open cholecystectomy (CO) group showed significant PO2 reduction at 4, 8, 12, and 24 hours post-surgery (P < 0.05).
- No significant PO2 reduction was observed in the laparoscopic cholecystectomy (CL) group.
- Atelectasis incidence was higher in the CO group (85%) compared to the CL group (55%) (P < 0.05).
Conclusions:
- Laparoscopic cholecystectomy (CL) appears to alter pulmonary function less than open cholecystectomy (CO).
- CL may be associated with a lower risk of postoperative pulmonary complications such as atelectasis and hypoxemia.
