Surgical Simulation: Enhancing Surgical Skills Training and Patient Safety

What is Surgical Simulation?

Surgical simulation involves replicating real-life surgical procedures using computer models, virtual reality technology, or surgical mannequins. This allows surgeons to practice and rehearse surgical techniques and scenarios in a safe, controlled environment before performing procedures on real patients.

Types of Surgical Simulation

There are different modalities used in surgical simulation:

Computer-Based Simulation: Computer-based surgical simulators use sophisticated 3D graphical engines and haptic feedback devices to model anatomy, tissue properties, and surgical instruments. This allows surgeons to perform virtual surgeries by interacting with realistic computer models. Common computer simulators are used for laparoscopy, endoscopy, orthopedic, and cardiac procedures.

Virtual Reality Simulation: Virtual reality simulators take computer modeling a step further by immersing the user within a fully virtual 3D environment. Surgeons wear VR headsets and use haptic tools to perform simulated procedures from a first-person perspective. This high level of immersion provides a highly realistic simulation experience.

Mannequin-Based Simulation: Mannequin-based simulators use physical models, such as entire body surgical mannequins or isolated organ models, to simulate anatomical structures and properties. Instruments are used directly on the models to practice technical skills. Some high-fidelity mannequin simulators reproduce physiological parameters like breathing, pulse, and bleeding.

Advantages of Surgical Simulation

Surgical simulation offers several benefits over traditional apprenticeship-based training methods:

Safe Practice Environment: Simulation allows surgeons to learn and make mistakes in a safe environment without putting real patients at risk. Complex or high-risk procedures can be practiced repeatedly.

Skills Assessment: Simulation provides objective metrics to measure and assess technical skills acquisition. Performance can be consistently evaluated against set benchmarks and competency standards.

Focused Skills Training: Specific techniques or rare cases can be isolated and drilled through repetition on simulators. Training focuses only on intended skills without distractions from the real operating room environment.

Reduce Training Time Pressure: Junior surgeons no longer have to learn complex tasks entirely in the operating room under time pressure. Basic skills can be gained through self-paced simulation practice before real cases.

Overcoming Access Barriers: Simulation makes it possible to practice procedures that may not be accessible or too rare at a particular training site. Regional simulators allow standardized access to a variety of simulated case experiences.

Areas of Surgical Simulation Application

Surgical simulation is being applied to train and assess skills across many surgical specialties:

General Surgery: Common procedurespracticed on simulators include laparoscopic cholecystectomy, hernia repair, appendectomy, colorectal surgery, and endoscopy. Basic tissue handling skills are also trained.

Orthopedic Surgery: Knee, hip, and shoulder arthroscopy and arthroplasty procedures are commonly simulated. Fracture fixation and manipulation, and trauma management skills are also simulated.

Urologic Surgery: Laparoscopic and robotic urologic procedures like prostatectomy, nephrectomy, and cystectomy are simulated. Endourology skills for ureteroscopy and cystoscopy are also practiced.

Obstetrics/Gynecology: Simulators are used for hysterectomy, myomectomy, cervix, and adnexal procedures. Basic Laparoscopic skills and endoscopic skills for hysteroscopy and colposcopy are trained.

Cardiac Surgery: Simulators model open and endoscopic cardiac procedures like bypass grafting, valve repair, and replacement. Beating heart and coronary anastomosis skills are practiced.

Other Applications

Beyond clinical training, simulation is also being used for surgical research, device and equipment testing, team training, and crisis resource management. Surgical simulators have become a critical tool for enhancing skills training and patient safety across many specialty areas.

Credentialing in Surgical Simulation

As the role of simulation expands, professional organizations are recognizing its importance in surgical education by incorporating simulators into credentialing processes. For Example:

The American College of Surgeons (ACS) now provides Fundamentals of Laparoscopic Surgery (FLS) and Fundamentals of Endoscopic Surgery (FES) certifications based on simulated performance assessments.

The American Board of Urology now requires supervised clinical practice supported by basic laparoscopy and endourology skills demonstrated using simulators as part of their certification process.

The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) endorses FLS as a mandatory prerequisite credential for gastrointestinal (GI) fellows starting advanced endoscopy training.

The American College of Obstetricians and Gynecologists (ACOG) recommends simulation-based training and basic skills assessment for female pelvic medicine and reconstructive surgery (FPMRS) certification.

Simulation has thus come to play an important role in competency evaluation and credentialing, which drives an increasing emphasis on its incorporation in surgical training at all levels globally. Formalized skills assessments add credibility and transportability to simulation-based learning outcomes.

Surgical simulation has enabled enhanced skill development through a safe, standardized, focused, and accessible means of training. It is becoming a critical component for training, competency assessment, credentialing, and continuing surgical education across most surgical specialties. In the decades to come, surgical simulation will likely play an even larger role in preparing skilled surgeons and improving patient outcomes.
