The Resection Map: A proposal for intraoperative hepatectomy guidance

Objective - To propose a new concept of an intra-operative 3D visualisation system to support hepatectomies. This system aims at improving the transfer of pre-operative planning into the intra-operative stage, both in laparoscopic and open approaches. Materials and methods - User (surgeon) centred developmental process to identify the surgical requirements is applied. The surgical workflow of hepatectomy is analyzed, including observations of liver surgeries and focus group sessions. Based on this analysis, specifications for the “ResectionMap” are defined. A first implementation is developed, and preliminary clinical acceptance results are gathered. Results - Control of main veins and tumour margins are the two critical aspects. The “Resection Map” provides an intuitive visualisation of structures nearby the resection plane without any registration to the patient space. The first prototype subjectively increases the surgeon’s confidence and orientation, but it should be further developed for non anatomical resections. Conclusions - The ResectionMap is proposed as a pragmatic solution to enhance liver resection accuracy and safety.Product Innovation ManagementIndustrial Design Engineerin
