Robotic-assisted surgery research has grown dramatically in the past two decades and the advantages over traditional videolaparoscopy have been extensively debated. For hernias, the robotic system can increase intraoperative strategies, especially in complex hernias or incisional hernias.
This study aimed to compare the direct cost differences between robotic and laparoscopic hernia repair and determine each source of expenditure that may be related to the increased costs in a robotic program from the perspective of a Brazilian public institution.
This study investigated the differences in direct costs from the data generated from a trial protocol (ReBEC: RBR-5s6mnrf). Patients with incisional hernia were randomly assigned to receive laparoscopic ventral incisional hernia repair (LVIHR) or robotic ventral incisional hernia repair (RVIHR). The direct medical costs of hernia treatment were described in the Brazilian currency (R$).
A total of 19 patients submitted to LVIHR were compared with 18 submitted to RVIHR. The amount spent on operation room time (RVIHR: 2,447.91±644.79; LVIHR: 1,989.67±763.00; p=0.030), inhaled medical gases in operating room (RVIHR: 270.57±211.51; LVIHR: 84.55±252.34; p=0.023), human resources in operating room (RVIHR: 3,164.43±894.97; LVIHR: 2,120.16±663.78; p<0.001), material resources (RVIHR: 3,204.32±351.55; LVIHR: 736.51±972.32; p<0.001), and medications (RVIHR: 823.40±175.47; LVIHR: 288.50±352.55; p<0.001) for RVIHR was higher than that for LVIHR, implying a higher total cost to RVIHR (RVIHR: 14,712.24±3,520.82; LVIHR: 10,295.95±3,453.59; p<0.001). No significant difference was noted in costs related to the hospital stay, human resources in intensive care unit and ward, diagnostic tests, and meshes.
Robotic system adds a significant overall cost to traditional laparoscopic hernia repair. The cost of the medical and robotic devices and longer operative times are the main factors driving the difference in costs.
