Introduction: Recent studies have suggested that laparoscopic surgery for colorectal resection confers a cost benefit compared with open surgery. These studies have considered a wide range of colorectal operations together rather than focusing on a single procedure. Our study compared direct clinical costs for laparoscopic versus open right hemicolectomy.
Methods: Clinicopathological data and cost of treatment for all patients who underwent a right hemicolectomy between 2012 and 2013 were collected. The primary outcome was total cost of treatment. Secondary outcomes were length of stay, operative time and morbidity. The minimum follow-up duration was 12 months. Costs for laparoscopic and open surgery for elective resection alone were compared. Further analyses were performed comparing emergency cases with elective cases and cancer with non-cancer cases.
Results: There were 83 patients who underwent a right hemicolectomy during the study period and of these, 65 had an elective procedure. The total cost of a laparoscopic procedure was £3,998.12 compared with £3,427.50 for open surgery (p=0.039). The length of stay was shorter for laparoscopic surgery while the cost of an emergency right hemicolectomy was significantly greater than for elective surgery.
Conclusions: Although the length of stay for laparoscopic surgery was shorter, this did not translate to a reduction in cost. The cost benefit from a shorter length of stay was offset by a greater cost of consumables. Cost effectiveness analyses should be designed carefully, and they should consider individual operations separately when making healthcare management and funding decisions.
