A population-based cohort study comparing laparoscopic cholecystectomy and open cholecystectomy

Area of Science:

• Surgical Outcomes Research
• Gastrointestinal Surgery
• Health Services Research

Background:

• Laparoscopic cholecystectomy (LC) is a common alternative to open cholecystectomy (OC).
• Previous comparative studies had limitations due to small patient cohorts and lack of comorbidity control.
• There is a need to evaluate LC and OC outcomes in large, unselected patient populations.

Purpose of the Study:

• To compare morbidity, mortality, and costs between LC and OC.
• To analyze outcomes in a large, population-based cohort.
• To assess the impact of patient comorbidities on surgical outcomes.

Main Methods:

• Utilized the North Carolina Discharge Abstract Database (1991-1994) for a cohort of 43,433 patients.
• Compared length of stay, hospital charges, complications, morbidity, and mortality between LC and OC groups.
• Employed regression analyses with the age-adjusted Charlson Comorbidity Index to control for patient differences.

Main Results:

• OC patients experienced longer hospitalizations, higher charges ($12,125 vs $9,139), and increased home care needs.
• The crude risk ratio for death in OC versus LC was 5.0.
• After adjusting for age and comorbidity, OC patients had 3.3 times greater odds of dying compared to LC patients.

Conclusions:

• Laparoscopic cholecystectomy (LC) has significantly lower mortality rates than open cholecystectomy (OC).
• LC is associated with reduced hospital costs and improved patient outcomes.
• LC is recommended as the treatment of choice for both acute and chronic cholecystitis.
