Surgical Simulation Curriculum
The University of Missouri Ob/Gyn residency program leads the way in integration of surgical simulation into early development of surgical skills.

| Intern Dr. Dan Jackson teaches a 4th year medical student how to perform a laparoscopic nephrectomy. |
 |
| Graduated chief resident Dr. Luis Espinoza (2008) teaches incoming intern Lauren Vestal basic hysterotomy closure. |
The residency transition into the real-world OR environment can be challenging. Our goal is to prepare you for live procedures by concurrently orienting you to anatomy and technique using surgical simulation. The simulated environment gives you time to process through early development of technique and skill in a “cold action” practice environment (Eraut, 1985) before proceeding into the “hot action” of the operating room.
Our program currently begins each July with a two-day, eight station Skills Camp experience where you learn and practice basic surgical component skills such as suturing, knot tying, incising skin without beveling, basic obstetrical exam for fetal vertex position, forcep and vacuum delivery, etc. During “surgical skill olympics” you will put your skill against other interns and residents using objective measures of these skills (don’t worry – only the top residents in each category are posted!). These objective scores allow you to quantify your surgical skill development as you progress through the program.

| Graduated chief Dr. Lisa Brennaman and perinatologist Dr. Randal Floyd (2008) teach basic obstetric laceration repair. |
To allow an objective measure of progress, all of our residents are given a numeric competency score following each real-world operating room experience. This private score is compiled into a spreadsheet to allow progress to be tracked throughout residency. A “1” means that more one-on-one “cold-action” instruction is needed with simulation. A “2” means that a resident is capable of performing some but not all elements of a procedure with guidance. A “3” means that a resident is capable of performing a complete procedure with supervision and is usually achieved in the 2nd or 3rd year depending on the procedure. The coveted “4” is usually achieved by the 3rd or 4th year for most procedures (ie., mid-urethral sling, vacuum or forcep delivery, vaginal hysterectomy, laparoscopic hysterectomy) and means that the faculty member is confident that a resident is capable of performing a procedure independently in private practice without any supervision.
Gynecological Surgery Simulation
Our gynecological surgery simulation begins with component skill simulation – suturing, knot tying, incising, and basic laparoscopic manipulation. We also use surgical videos and models (and in the near future cadavers) to review pelvic anatomy. Our residents are expected to practice these skills until they are proficient.

Models available in our Medical Education Suite at Columbia Regional Hospital are to be used for gynecological surgery practice, include laparoscopic video box trainers, suture sets, surgical videos, and laparotomy and vaginal hysterectomy models. At any time, our residents are encouraged to “test out” and beat their previous score obtained in “component skills olympics”. The highest scores in the residency are posted for each skill.
We hold twice a year departmental animate laparoscopic surgery labs (using pigs) in which we perform hysterectomy, cystectomy, nephrectomy, ureteral dissection, and bowel repair. Port placement (Veress needle, open and closed entry, direct entry and optical entry) can be practiced during these afternoon labs.
Three of residents a month participate in a laparoscopy training day sponsored by our General Surgery Department’ Division of Minimally Invasive Surgery in the Sheldon Simulation Center on the main University of Missouri Campus. Our residents hone their advanced laparoscopic skill and gain experience in gastrointestinal procedures such as bowel resection/ reanastomosis, cholecystectomy, and laparoscopic hernia repair which translates into increased confidence and technical skill in performing gynecological laparoscopic procedures. Beginning in 2009, all second-year residents will participate in the SAGES Fundamental Laparoscopic Skills certification exam.
Obstetrical Surgery Simulation

| Faculty member Dr. Michael McCullough demonstrates a forcep-assisted vaginal delivery using our department’s Clinical Innovations high fidelity delivery simulator. |
In addition to gynecological procedure simulation, our residents participate in our Obstetric Emergencies Course – an extremely popular course given for a fee to obstetricians in private practice – where they are given the opportunity to use our Noelle birth simulators to treat eclampsia, severe postpartum hemorrhage, precipitous vaginal breech delivery, etc.
Operative vaginal deliveries – both vacuum and forcep – are practiced using our Kiwi Vac high fidelity delivery simulator. This silicon pelvis is incredibly life-like, with anatomical landmarks such as pubic arch and spines, and allows for forcep and vacuum simulation that is difficult to distinguish from reality.
Repair of 3rd and 4th degree lacerations is accomplished during our Skills Camp using the Beef Tongue Obstetric Laceration Model. This excellent experience is helpful in orienting our residents to these important repairs before they are called on to perform one in the middle of the night on call!
Communication and Professionalism Simulation

We are proud to partner with the Sheldon Simulation Center on main campus, 4.5 miles away. The Sheldon Simulation Center is a cutting-edge multimedia capable center with multiple videotaped exam rooms and simulated OR environment that can be used to evaluate a trainees response to common and uncommon clinical situations. Once a year, our curriculum includes an afternoon in the simulation center using gynecological teaching assistants to evaluate and teach skills such as informed consent, delivering bad news and dealing with the difficult patient or colleague. This experience is invaluable for developing a sense of constructive self-awareness in professional development.
Summary
We are committed to providing the very best educational experience for our residents. Simulation is an important tool in this process, especially early in training. Our vision is to maximize the use of this tool to give our residents a “jump start” into the surgical arena, allowing “real-world” OR experiences to be more meaningful and less stressful for all of our resident surgeons.
