“…Laparoscopic imaging is an optical, non-invasive and non-ionizing technology that provides surgeons with 2D images, with three (e.g., in case of RGB) or more channels, of the surgical scene. With respect to other imaging modalities (such as MRI and X-ray), endo/laparoscopic imaging is also fully compatible with standard OR instrumentation [169].…”

With the advent of Minimally Invasive Surgery (MIS), intra-operative imaging has become crucial for surgery and therapy guidance, allowing to partially compensate for the lack of information typical of MIS. This paper reviews the advancements in both classical (i.e. ultrasounds, X-ray, optical coherence tomography and magnetic resonance imaging) and more recent (i.e. multispectral, photoacoustic and Raman imaging) intra-operative imaging modalities. Methods Each imaging modality was analyzed, focusing on benefits and disadvantages in terms of compatibility with the operating room, costs, acquisition time and image characteristics. Tables are included to summarize this information. New generation of hybrid surgical room and algorithms for real time/in room image processing were also investigated. Results Each imaging modality has its own (site-and procedure-specific) peculiarities in terms of spatial and temporal resolution, field of view and contrasted tissues. Besides the benefits that each technique offers for guidance, considerations about operators and patient risk, costs, and extra time required for surgical procedures have to be considered. The current trend is to equip surgical rooms with multimodal imaging systems, so as to integrate multiple information for real-time data extraction and computer-assisted processing. Conclusions The future of surgery is to enhance surgeons eye to minimize

“…In our laboratory, based on preliminary work by Tamadazte et al [14,19], we developed an Enhanced Laparoscopy Vision System (ELViS) to overcome the blind spots inherent to laparoscopic surgery. The system is a camera trocar that has been "augmented" by two miniature cameras.…”

Background: The absence of visibility of the entire surgical scene in laparoscopic surgery can lead to unforeseen intraoperative complications. An Enhanced Laparoscopy Vision System (ELViS) was developed to eliminate the blind spots of the traditional endoscope by providing a broad view of the surgical scene from a distance, thanks to two additional images. This study assessed whether the broad view provided by the Enhanced Laparoscopic Vision (ELV) helped the surgeon to detect and react to an unexpected intraoperative adverse event (simulated hemorrhage) occurring while performing a standard task.Methods: While participants were performing a standard task (sorting pins) on a dry lab laparoscopic simulator with or without ELV, a simulated bleeding (LED lighting) was randomly triggered. Perprocedure metrics were recorded and surgeons' feedback gathered at the end of the session.Results: Thirteen Senior surgeons participated. Mean response time was significantly reduced when using ELV, with a similar number of simulated bleeding events between both modalities. All surgeons agreed that ELV could be helpful and constitutes an acceptable increase in cognitive load. Conclusion:In a dry lab setup, compared to traditional endoscopy, the broader field of view provided by ELV improved outcomes when dealing with unforeseen complications like bleeding.

“…Both the MARVEL and the VTEI systems intend to provide an enlarged FoV comparable to that of an open-cavity surgery. In addition to the MARVEL and the VTEI systems, a multi-view visualization system was developed to enlarge FoV by using two miniaturized cameras and a conventional endoscope [20]. This visualization system reduced both the procedure time and the number of commands for operating the robotic endoscope holder.…”

Existing laparoscopic surgery systems use a single laparoscope to visualize the surgical area with a limited field of view (FoV), necessitating maneuvering the laparoscope to search a target region. In some cases, the laparoscope needs to be moved from one surgical port to another one to detect target organs. These maneuvers would cause longer surgical time and degrade the efficiency of operation. We hypothesize that if an array of cameras can be deployed to provide a stitched video with an expanded FoV and small blind spots, the time required to perform multiple tasks at different sites can be significantly reduced. We developed a micro-camera array that can enlarge the FoV and reduce blind spots between the cameras by optimizing the angle of cameras. The video stream of this micro-camera array was designed to be processed in real-time to provide a stitched video with the expanded FoV. We mounted this micro-camera array to a Fundamentals of Laparoscopic Surgery (FLS) laparoscopic trainer box and designed an experiment to validate the hypothesis above. Surgeons, residents, and a medical student were recruited to perform a modified bean drop task, and the completion time was compared against that measured using a traditional single-camera laparoscope. It was observed that utilizing the micro-camera array, the completion time of the modified bean drop task was 203 ± 55 s while using the laparoscope, the completion time was 245 ± 114 s, with a p-value of 0.00097. It is also observed that the benefit of using an FoV-expanded camera array does not diminish for subjects who are more experienced. This test provides convincing evidence and validates the hypothesis that expanded FoV with small blind spots can reduce the operation time for laparoscopic surgical tasks.

Multi-view vision system for laparoscopy surgery

Abstract: An augmented laparoscopy system with increased field of view is feasible and may be advantageous compared with a traditional endoscope. In vivo testing of the system should be done to establish the clinical utility of this innovation.
