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 surge
ry.
Design: Retrospective cost-effectiveness analysis evaluating all cases perf
ormed in a 36-month period (September 1995 to August 1998). Cases were eval
uated for operative time, itemized cost of supplies, and length of hospital
ization.
Setting: Operations performed by pediatric surgeons in a tertiary care chil
dren's hospital.
Patients: Consecutive children undergoing laparoscopic or open appendectomi
es, cholecystectomies, fundoplications, and splenectomies. Patients were no
t randomized to laparoscopy or open surgery.
Interventions: Laparoscopic procedures performed with a core set of reusabl
e equipment and a limited number of disposable instruments.
Main Outcome Measures: Cost surplus of laparoscopy was evaluated, and compa
red with savings associated with decreased hospital stay, to obtain cost-ef
fectiveness of laparoscopy per procedure.
Results: There were 26 laparoscopic and 359 open appendectomies; 33 laparos
copic and 3 open cholecystectomies; 16 laparoscopic and 18 open fundoplicat
ions; and 16 laparoscopic and 7 open splenectomies. Excess operating costs
per procedure were $442.00 for appendectomy, $634.60 for fundoplication, $8
47.50 for cholecystectomy, and $1551.30 for splenectomy. Hospital stay tvas
decreased for all laparoscopies, resulting in an overall savings per lapar
oscopic 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, opera
ting time, and length of stay allows interinstitutional comparison and crit
ical cost-analysis of laparoscopy. With a more selective use of reusable in
struments and further shortening of operative time, the global savings of l
aparoscopy may increase.
