  • effect of training and instrument type on performance in single incision laparoscopy results of a randomized comparison using a Surgical Simulator
    Surgical Endoscopy and Other Interventional Techniques, 2011
    Co-Authors: Byron F Santos, Nathaniel J. Soper, Taylor J Reif, Eric S. Hungness
    Abstract:

    Single-incision laparoscopy (SIL) is potentially less invasive compared with standard laparoscopic surgery (LAP); however, it may be more technically challenging and have a longer learning curve. A two-phase study was conducted to examine the performance of standardized tasks on a Surgical Simulator by novices during a distributed training period. Phase 1 examined the effect of LAP-specific or SIL-specific training on skill acquisition for both techniques. Phase 2 compared the effectiveness and learning curves of additional instrument types for SIL (straight [STR] vs. dynamic articulating [D-ART]). Medical students without previous Surgical experience were randomized to LAP-specific training or SIL-specific training, using static articulating instruments [S-ART] for SIL. LAP and SIL scores on the peg transfer (PEG) and pattern cutting (CIRCLE) tasks from the Fundamentals of Laparoscopic Surgery (FLS) were measured at baseline and after four training sessions. In phase 2, a new group of subjects were randomized to SIL training using STR or D-ART instruments, with similar baseline and post-training testing. FLS task scores were calculated and compared according to training regimen and instrument type. Forty-five subjects completed the study. All scores improved significantly during the training period. Improvement in LAP score was similar between LAP-trained and SIL-trained groups. Improvement of SIL score was better for the SIL-trained group. Final scores were better and the learning curve was shorter for LAP versus SIL technique, with no differences in SIL scores according to instrument type. LAP technique results in superior task performance with a shorter learning curve compared with SIL technique during a standardized training period. SIL-specific Simulator training is better than LAP training alone to improve SIL performance. Neither S-ART nor D-ART instruments for SIL are associated with improved performance or shorter learning curve compared with STR instruments.

    Abstract:

    Single-incision laparoscopic surgery (SILS™) is a potentially less invasive approach than standard laparoscopy (LAP). However, SILS™ may not allow the same level of manual dexterity and technical performance compared to LAP. We compared the performance of standardized tasks from the Fundamentals of Laparoscopic Surgery (FLS) program using either the LAP or the SILS™ technique. Medical students, Surgical residents, and attending physicians were recruited and divided into inexperienced (IE), laparoscopy-experienced (LE), and SILS™-experienced (SE) groups. Each subject performed standardized tasks from FLS, including peg transfer, pattern cutting, placement of ligating loop, and intracorporeal suturing using a standard three-port FLS box-trainer with standard laparoscopic instruments. For SILS™, the subjects used an FLS box-trainer modified to accept a SILS Port™ with two working ports for instruments and one port for a 30° 5-mm laparoscope. SILS™ tasks were performed with instruments capable of unilateral articulation. SILS™ suturing was performed both with and without an articulating EndoStitch™ device. Task scores, including cumulative laparoscopic FLS score (LS) and cumulative SILS™ FLS score (SS), were calculated using standard time and accuracy metrics. There were 27 participants in the study. SS was inferior to LS in all groups. LS increased with experience level, but was similar between LE and SE groups. SS increased with experience level and was different among all groups. SILS™ suturing using the articulating suturing device was superior to the use of a modified needle driver technique. SILS™ is more technically challenging than standard laparoscopic surgery. Using currently available SILS™ platforms and instruments, even surgeons with SILS™ experience are unable to match their overall LAP performance. Specialized training curricula should be developed for inexperienced surgeons who wish to perform SILS™.

  • Virtual Functional Endoscopic Sinus Surgery Simulation with 3D-Printed Models for Mixed-Reality Nasal Endoscopy
    Otolaryngology–Head and Neck Surgery, 2018
    Co-Authors: Samuel R. Barber, Youngjun Son, Saurabh Jain, Eugene H. Chang
    Abstract:

    The surgeon's knowledge of a patient's individual anatomy is critical in skull base surgery. Trainees and experienced surgeons can benefit from Surgical simulation; however, current models are expensive and impractical for widespread use. In this study, we report a next-generation mixed-reality Surgical Simulator. We segmented critical anatomic structures for 3-dimensional (3D) models to develop a modular teaching tool. We then developed a navigation tracking system utilizing a 3D-printed endoscope as a trackable virtual-reality (VR) controller and validated the accuracy on VR and 3D-printed skull models within 1 cm. We combined VR and augmented-reality visual cues with our 3D physical model to simulate sinus endoscopy and highlight segmented structures in real time. This report provides evidence that a mixed-reality Simulator combining VR and 3D-printed models is feasible and may prove useful as an educational tool that is low cost and customizable.
