Image-guided laparoscopic surgery. Review and current status

Area of Science:

• Medical Imaging
• Surgical Technology
• Minimally Invasive Surgery

Background:

• Laparoscopic surgery lacks tactile feedback and provides only surface views, hindering identification of subsurface structures like vessels and tumors.
• Current visualization methods in laparoscopy are insufficient for complex anatomical regions, increasing surgical risks.
• There is a critical need for advanced visualization techniques to augment surgical planning and intraoperative guidance.

Purpose of the Study:

• To review the state-of-the-art in image-guided laparoscopic surgery.
• To present a prototype navigation system for advanced visualization in retroperitoneal laparoscopic procedures.
• To demonstrate the potential of 3D navigation technology in enhancing laparoscopic surgery.

Main Methods:

• Literature review of image-guided laparoscopic surgery techniques.
• Development and testing of a prototype 3D navigation system using preoperatively acquired MRI/CT data.
• Integration of tracked instruments with interactive image display for intraoperative guidance.

Main Results:

• The prototype system enables interactive control of displayed images, integrating pre-operative data with real-time surgical views.
• Advanced visualizations improve the surgeon's understanding of anatomy and location of critical structures, such as blood vessels.
• Clinical studies are underway to further develop and validate the technology in a 'Future Operating Room' setting.

Conclusions:

• Image-guided abdominal navigation with tracked instruments and advanced visualization significantly improves laparoscopic surgery.
• This technology enhances safety and ease of performing complex laparoscopic procedures, particularly when subsurface anatomy is difficult to discern.
• The system holds substantial potential for advancing minimally invasive surgical techniques and improving patient outcomes.
