“…Laparoscopic ultrasound is a useful tool for obtaining information on embedded vascular structures around surgical target regions during laparoscopic surgery. Several research groups have presented the surgical navigation system combined with laparoscopic ultrasound [35]. Ultrasound is useful for observing inside solid organs such as the liver.…”

“…During image-guided surgery, diagnostic imaging is used in conjunction with images from the operative field to improve the localization and targeting of pathologies, as well as to monitor and control treatments. The combination of tracking technologies for recording the position of the patient and the surgical instruments with preoperative and intraoperative images provides a comprehensive assistance tool for guiding any MIS intervention [27,[89][90][91]. Image-guided technology allows for more precise and accurate procedures, allowing surgeons to decide the best approach to address a specific disease before the intervention [92].…”

Pancreatic ductal adenocarcinoma (PDA) is the fourth leading cause of cancer-related deaths. Surgery is the only viable treatment, but irradical resection rates are still high. Laparoscopic pancreatic surgery has some technical limitations for surgeons and tumor identification may be challenging. Image-guided techniques provide intraoperative margin assessment and visualization methods, which may be advantageous in guiding the surgeon to achieve curative resections and therefore improve the surgical outcomes. In this chapter, current available laparoscopic surgical approaches and image-guided techniques for pancreatic surgery are reviewed. Surgical outcomes of pancreaticoduodenectomy and distal pancreatectomy performed by laparoscopy, laparoendoscopic single-site surgery (LESS), and robotic surgery are included and analyzed. Besides, image-guided techniques such as intraoperative near-infrared fluorescence imaging and surgical navigation are presented as emerging techniques. Results show that minimally invasive procedures reported a reduction of blood loss, reduced length of hospital stay, and positive resection margins, as well as an improvement in spleenpreserving rates, when compared to open surgery. Studies reported that fluorescenceguided pancreatic surgery might be beneficial in cases where the pancreatic anatomy is difficult to identify. The first approach of a surgical navigation system for guidance during pancreatic resection procedures is presented, combining preoperative images (CT and MRI) with intraoperative laparoscopic ultrasound imaging.

“…17 Additionally, we believe that because sweeping a LUS is more similar to intraoperative actions than defining landmarks, this technique would lead to a fast and intuitive work flow. Whereas previous works 15,18,19 have reported the use of US-based 3D volumes, in the context of enhanced US guidance, to date, this technique has not been reported in the context of registration for laparoscopic IGS. In this work, we present a novel registration method that reconstructs an intraoperative US-based 3D volume of the intrahepatic vessel anatomy and register it with the preoperative 3D model.…”

Background. Patient-to-image registration is a core process of image-guided surgery (IGS) systems. We present a novel registration approach for application in laparoscopic liver surgery, which reconstructs in real time an intraoperative volume of the underlying intrahepatic vessels through an ultrasound (US) sweep process. Methods. An existing IGS system for an open liver procedure was adapted, with suitable instrument tracking for laparoscopic equipment. Registration accuracy was evaluated on a realistic phantom by computing the target registration error (TRE) for 5 intrahepatic tumors. The registration work flow was evaluated by computing the time required for performing the registration. Additionally, a scheme for intraoperative accuracy assessment by visual overlay of the US image with preoperative image data was evaluated. Results. The proposed registration method achieved an average TRE of 7.2 mm in the left lobe and 9.7 mm in the right lobe. The average time required for performing the registration was 12 minutes. A positive correlation was found between the intraoperative accuracy assessment and the obtained TREs. Conclusions. The registration accuracy of the proposed method is adequate for laparoscopic intrahepatic tumor targeting. The presented approach is feasible and fast and may, therefore, not be disruptive to the current surgical work flow.
