Abstract
BACKGROUND: There has been a rapid adoption of robot-assisted laparoscopic inguinal hernia repair in the USA, despite a lack of proven clinical advantage and higher material cost. No studies have been published regarding the cost and outcome of robotic inguinal hernia surgery in a European Union setting. METHODS: A retrospective comparative study was performed on the early outcome and costs related to laparoscopic inguinal hernia repair, with either conventional or robot-assisted surgery. RESULTS: The study analysed 676 patients undergoing laparoscopic inguinal hernia repair (272 conventional and 404 robotic repairs). Conventional laparoscopic and robotic repair groups were comparable in terms of duration of surgery (57.6 versus 56.2 min respectively; P = 0.224), intraoperative complication rate (1.1 versus 1.2 per cent; P = 0.990), in-hospital complication rate (4.4 versus 4.5 per cent; P = 0.230) and readmission rate (3.3 versus 1.2 per cent; P = 0.095). There was a significant difference in hospital stay in favour of the robotic approach (P = 0.014), with more patients treated on an outpatient basis in the robotic group (59.2 per cent versus 70.0 per cent for conventional repair). At 4-week follow-up, equal numbers of seromas or haematomas were recorded in the conventional laparoscopic and robotic groups (13.3 versus 15.7 per cent respectively; P = 0.431), but significantly more umbilical wound infections were seen in the conventional group (3.0 per cent versus 0 per cent in the robotic group; P = 0.001). Robotic inguinal hernia repair was significantly more expensive overall, with a mean cost of €2612 versus €1963 for the conventional laparoscopic approach (mean difference €649; P < 0.001). CONCLUSION: Robot-assisted laparoscopic inguinal hernia repair was significantly more expensive than conventional laparoscopy. More patients were treated as outpatients in the robotic group. Postoperative complications were infrequent and mild.
