Introduction of laparoscopic gastrectomy for gastric cancer in a Western tertiary referral centre: A prospective cost analysis during the learning curve

AIM To evaluate the costs of the introduction of a laparoscopic surgery program for gastric cancer in a Western community training hospital and tertiary referral centre for gastric cancer surgery. METHODS All patients who underwent surgery for gastric cancer with curative intent in 2013 and 2014 were prospectively included. Primary outcomes were costs regarding surgery and hospital stay. RESULTS Laparoscopic gastrectomy was used in 52 patients [mean age 68 years (± 9, range 50 to 87)] and open gastrectomy was used in 25 patients [mean age 70 years (± 10, range 46 to 85)]. Mean costs (in euro's) of surgical instrumentation were significantly higher for laparoscopic surgery: 2270 ± 670 vs 1181 ± 680 in the open approach (P < 0.001). Costs of theatre use were higher in the laparoscopic group: mean 3819 ± 865 vs 2545 ± 1268 in the open surgery (P < 0.001). Total costs of hospitalization (i.e., costs of surgery and admission) were not different between laparoscopic and open surgery, 8187 ± 4864 and 7673 ± 8064 respectively (P = 0.729). Mean length of hospital stay was 9 ± 12 d in the laparoscopic group vs 14 ± 14 d in the open group (P = 0.044). CONCLUSION The introduction of laparoscopic gastrectomy for gastric cancer coincided with higher costs for theatre use and surgical instrumentation compared to the open technique. Total costs were not significantly different due to shorter length of stay and less intensive care unit (ICU) admissions and shorter ICU stay in the laparoscopic group.
