Cost-effectiveness of laparoscopy in children.

BACKGROUND

Laparoscopy may offer fast recovery and improved cosmesis, but its cost has been perceived as excessive.

OBJECTIVE

To analyze the total hospital costs of laparoscopy vs open surgery.

DESIGN

Retrospective cost-effectiveness analysis evaluating all cases performed in a 36-month period (September 1995 to August 1998). Cases were evaluated for operative time, itemized cost of supplies, and length of hospitalization.

SETTING

Operations performed by pediatric surgeons in a tertiary care children's hospital.

PATIENTS

Consecutive children undergoing laparoscopic or open appendectomies, cholecystectomies, fundoplications, and splenectomies. Patients were not randomized to laparoscopy, or open surgery.

INTERVENTIONS

Laparoscopic procedures performed with a core set of reusable equipment and a limited number of disposable instruments.

MAIN OUTCOME MEASURES

Cost surplus of laparoscopy was evaluated, and compared with savings associated with decreased hospital stay, to obtain cost-effectiveness of laparoscopy per procedure.

RESULTS

There were 26 laparoscopic and 359 open appendectomies; 33 laparoscopic and 3 open cholecystectomies; 16 laparoscopic and 18 open fundoplications; and 16 laparoscopic and 7 open splenectomies. Excess operating costs per procedure were $442.00 for appendectomy, $634.60 for fundoplication, $847.50 for cholecystectomy, and $1551.30 for splenectomy. Hospital stay was decreased for all laparoscopies, resulting in an overall savings per laparoscopic procedure of $2369.90 for appendectomy, $5390.90 for fundoplication, $1161.00 for cholecystectomy, and $858.90 for splenectomy.

CONCLUSIONS

Laparoscopy is cost-effective, particularly for fundoplication, appendectomy, and cholecystectomy. Detailing the costs of supplies, operating time, and length of stay allows interinstitutional comparison and critical cost-analysis of laparoscopy. With a more selective use of reusable instruments and further shortening of operative time, the global savings of laparoscopy may increase.
