Economic evaluation of minimally invasive colectomy

Area of Science:

• Colorectal Surgery
• Surgical Outcomes Research
• Health Economics

Background:

• Minimally invasive colectomy (MIC) may involve longer operative times and increased equipment costs compared to open colectomy (OC).
• Potential benefits of MIC include reduced pain, earlier oral feeding, and shorter hospitalizations.

Purpose of the Study:

• To conduct a cost-benefit analysis comparing minimally invasive colectomy (MIC) and open colectomy (OC).
• To evaluate the economic implications and clinical outcomes of MIC versus OC.

Main Methods:

• A retrospective review of operating room records for open colectomies (OCs) and minimally invasive colectomies (MICs) performed between January 1, 2000, and March 31, 2004.
• Calculation of operating room times, total operating room costs, length of hospital stay, and total hospital costs for each procedure.

Main Results:

• MIC procedures (right and left hemicolectomies) had significantly longer operating room times compared to OC (p=0.01 for right, p=0.005 for left).
• Hospital stays were significantly shorter for MIC compared to OC (p=0.004 for right, p=0.001 for left).
• Total hospital costs were significantly lower for MIC ($8,580 ± $1,358) compared to OC ($10,303 ± $3,299) (p=0.046).

Conclusions:

• Minimally invasive colectomy (MIC) is associated with longer operating room times but shorter hospital stays than open colectomy (OC).
• While operating room costs are higher for MIC, overall hospital costs are significantly lower.
• MIC is a cost-effective procedure, yielding substantial savings for the healthcare system.
