Solid Pseudopapillary Neoplasm

Solid pseudopapillary neoplasm (SPN) is a rare tumor of the pancreas. Laparoscopic distal pancreatectomy (DP) is a feasible and safe procedure, and successful spleen preservation rates are higher using a laparoscopic approach. We hypothesized that certain patients with SPN would be good candidates for laparoscopic surgery; however, few surgeons have reported laparoscopic DP for SPN. We discuss the preoperative assessment and surgical simulation for two SPN cases. A simulation was designed because we consider that a thorough preoperative understanding of the procedure based on three-dimensional image analysis is important for successful laparoscopic DP. We also discuss the details of the actual laparoscopic DP with or without splenic preservation that we performed for our two SPN cases. It is critical to use appropriate instruments at appropriate points in the procedure; surgical instruments are numerous and varied, and surgeons should maximize the use of each instrument. Finally, we discuss the key techniques and surgical pitfalls in laparoscopic DP with or without splenic preservation. We conclude that experience alone is inadequate for successful laparoscopic surgery.

Special Instrumentation

Currently, there is a great interest in the use of minimally invasive surgery methods. Such surgeries require special instrumentation. Doctors increasingly use medical robots that replace assistants responsible for setting the position and orientation of the endoscope (vision), as well as make it possible to control surgical instruments. One of very promising fields of expansion of this technology is veterinary medicine. This article presents a review of literature on animal laparoscopic surgery with the use of medical robots. Particular attention was paid to animal experiments involving the Robin Heart family robots. Moreover, the article presents the construction and principle of operation of the smallest manipulator of the Robin Heart family, as well as describes preliminary simulations of surgery with the use of this robot. In the conclusion, possible directions for further improvement and implementation of the Robin Heart robot have been formulated.

Human Sense

This project concerns the application of haptic feedback to a virtual reality laparoscopic surgery simulator. It investigates the hardware required to display haptic forces, and the software required to generate realistic and stable haptic properties. A number of surgery-based studies are undertaken using the developed haptic device. The human sense of touch, or haptic sensory system, is investigated in the context of laparoscopic surgery, where the long laparoscopic instruments reduce haptic sensation. Nonetheless, the sense of touch plays a vital role in navigation, palpation, cutting, tissue manipulation, and pathology detection in surgery. The overall haptic effect has been decomposed into a finite number of haptic attributes. The haptic attributes of mass, friction, stiction, elasticity, and viscosity are individually modeled, validated, and applied to virtual anatomical objects in visual simulations. There are times in surgery when the view from the camera cannot be depended upon. When visual feedback is impeded, haptic feedback must be relied upon more by the surgeon. A realistic simulator should include some sort of visual impedance. Results from a simple tissue holding task suggested the inclusion of haptic feedback in a simulator aids the user when visual feedback is impeded.

Training Time

The ubiquitous nature of laparoscopic surgery and the decreased training time available for surgeons are driving an increased need for effective training systems to help surgeons learn different procedures. A cost-effective and user-friendly simulator has been designed to imitate specific training tasks for laparoscopic surgery in virtual environments via image processing and computer vision. The capability of using various actual surgical instruments suited for these specific procedures gives heightened fidelity to the simulator. Image processing via matlab software provides real-time mapping of the graspers in the workspace to the virtual reality (VR) environment (vizard software). Two different tasks (peg transfer and needle passing) were designed to evaluate trainees and compare their performance with characteristics of expert surgeons. Pilot testing of the system was carried out with 11 subjects to validate the similarity of this device with an existing surgical box trainer. Task completion time and muscle activity have been used as metrics for evaluation. The decrease in completion time for all subjects suggests similarity of skills transfer for both simulators. In addition, the p-value of muscle activity showed no significant differences for most muscles in the peg transfer task when using either the VR or physical analog environment and no significant differences for about half of the muscles in the needle passing task. Based on the results, the new proposed VR simulator appears to be a viable alternative to help trainees gain laparoscopic skills.
