Surgical dummy: a surrogate to live animal in teaching Veterinary Surgery
The objective of this study was to evaluate a non animal teaching model referred as surgical dummy, for teaching surgery, to novice veterinary students. Students' confidence level and experience in surgical practice was evaluated via questionnaire. In addition student observation was done during the practices by the instructor. The results show that students who first practiced using the surgical dummy had better psychomotor and basic surgical skills. Comments made by the students were positive in relation to sensation of tissue during handling rated as natural. Their confidence increased during surgical procedure due to freedom from worry of consequences of surgical errors. Students had the opportunity to practice adlibitum as the dummy was economical and simple to make. The skill gained in the dummy was adaptable to live animal surgery and decreased the use of cadaver or live animal utilization.

New Alternative to Animal Models for Surgical Training
Alternatives to Laboratory Animals, 2004
Laboratory training models are essential for developing and refining surgical skills, especially in microsurgery. A perfect training model is the one that can provide the same situation during surgery, in the same anatomy; the closer to live surgery the model is, the greater the benefit. The lack of an accurate vascular model has sometimes necessitated the use of live models when bleeding, and vascular liquid filling is desired for optional learning. We developed a new model utilising human cadavers that can replace the use of live anaesthetised animals for surgical training. The vessels in a cadaveric specimen were connected to artificial blood reservoirs. The arterial side was connected to a pump to provide pulsating pressure inside the arteries, while the venous side was kept under static pressure that applied to the reservoir. This method provides a condition that simulates live surgery in terms of bleeding, pulsation and liquid filling of the vascular tree. It is an excellent a...

Background: Numerous models, of variable quality, exist to impart the complex skills required to perform vascular anastomosis. These models differ with regard to the kinds of materials used, as well as their sizes, the time needed for their preparation, their availability, and the associated costs. The present study describes a bench model that uses formalin-fixed porcine aorta, and its evaluation by young surgical residents during a recent skills course.

Anatomia, Histologia, Embryologia: Journal of Veterinary Medicine Series C, 2007
Due to a raised ethical mentality, veterinary schools are pursuing methods to preserve animal corpses used for surgical technique classes in an attempt to reduce the use of living animals for teaching. Generally speaking, animal and human bodies are usually preserved with 10% aqueous formalin solution especially for descriptive anatomy classes. Other possibilities include the use of glycerol, alcohol and phenol. At present, new fixatives have been developed to allow a better and longer preservation of animal corpses in order to maintain organoleptic characteristics, i.e. colour, texture, as close as possible to what students will deal with living animals. From 2004, in our college, surgical technique classes no longer use living animals for studentsÕ training. Instead, canine corpses chemically preserved with modified Larssen (MLS) and Laskowski (LS) solutions are preferred. The purpose of this study was to investigate comparatively the biological quality of preservation of these two solutions and to evaluate studentsÕ learning and acceptance of this new teaching method. Although these fixatives maintain body flexibility, LS solution failed to keep an ordinary tissue colouration (cadavers were intensely red) and tissue preservation was not adequate. By contrast, MLS solution, however, did not alter the colouration of cadavers which was fairly similar to that normally found in living animals. A remarkable characteristic was a very strong and unpleasant sugary odour in LS-preserved animals and therefore the MLS solution was the elected method to preserve cadavers for surgical technique classes. The studentsÕ feedback to the use of Larssen-preserved cadavers was very satisfactory, i.e. 96.6% of students were in favour of the use of cadavers for surgical training and on average 91. 8% (2002-2003) of students preferred the MLS solution as the chemical preserver, whereas only 8.2% elected LS solution for teaching purposes. From the studentsÕ point of view (95.1%) the ideal class would be an initial training in MLS cadavers followed by classes with animals admitted to the Veterinary Hospital.
Evaluation of Video Tape and a Simulator for Instruction of Basic Surgical Skills
Veterinary Surgery, 1991
Twenty first-year veterinary students with no prior participatory experience in surgery were randomly paired and assigned into two study groups. Ten students (group V) viewed a hemostatic technique video tape until they thought they could competently perform and assist in performing a hand-tied ligature on a blood vessel in a live animal. Ten students (group VS) were also given a simulator for technique practice. Paired students were video recorded and blindly evaluated on their ability to perform and assist proper ligation of a bleeding vessel. Inexpensive hemostasis models were very helpful for teaching students essential surgeon and assistant skills involved in hand-tied ligature placement. Students who practiced with simulators performed significantly better as surgeon and assistant, and in total psychomotor skill evabation, than students watching the video only. Students using simulators performed ligation with significantly more accuracy and tended to be more expeditious at this task. Further training is needed for students to acquire skills necessary for efficient bleeding vessel exposure and isolation.
Laparoscopic surgical education--the experience of the first surgical unit Iaşi
Chirurgia, 2011
The classic apprenticeship model for surgical training takes place into the operating theater under the strict coordination of a senior surgeon. During the time and especially after the introduction of minimally invasive techniques as gold standard treatment for many diseases, other methods were developed to successful fulfill the well known three stages of training: skill-based behavior, rule-based behavior and knowledge-based behavior. The skills needed for minimally invasive surgery aren't easily obtained using classical apprenticeship model due to ethical, medico-legal and economic considerations. In this way several types of simulators have been developed. Nowadays simulators are worldwide accepted for laparoscopic surgical training and provide formative feedback which allows an improvement of the performances of the young surgeons. The simulators currently used allow assimilating only skill based behavior and rule-based behavior. However, the training using animal models a...

Objective. improve competency of residents with lysis of adhesion (LOA) and bowel surgery using a porcine model. Study Design. Pig bowel was removed at time of an anatomy laboratory, cleansed, and used to demonstrate surgical techniques and principles of LOA, repair of enterotomy, bowel resection, and anastomosis. Participants were surveyed pre- and posttraining session using 10 point Likert scale. Results. Thirty one residents at varying levels of training participated. After the training session, there was a significant improvement noted in mean scores for comfort level with LOA (6.3 versus 7.7, P = .007), comfort level with enterotomy repair (2.8 versus 6.4, P < .0001), understanding principles of LOA (5.0 versus 7.7, P < .0001), understanding principles of enterotomy repair (3.5 versus 7.0, P < .0001), and familiarity with instruments used (5.8 versus 7.3, P = .01). Conclusion. Training sessions using ex-vivo porcine model improve resident perception of knowledge and co...
A cost-effective approach to establishing a surgical skills laboratory
Surgery, 2007
Recent studies comparing inexpensive low-fidelity box trainers to expensive computer-based virtual reality systems demonstrate similar acquisition of surgical skills and transferability to the clinical setting. With new mandates emerging that all surgical residency programs have access to a surgical skills laboratory, we describe our cost-effective approach to teaching basic and advanced open and laparoscopic skills utilizing inexpensive bench models, box trainers, and animate models. Open models (basic skills, bowel anastomosis, vascular anastomosis, trauma skills) and laparoscopic models (basic skills, cholecystectomy, Nissen fundoplication, suturing and knot tying, advanced in vivo skills) are constructed using a combination of materials found in our surgical research laboratories, retail stores, or donated by industry. Expired surgical materials are obtained from our hospital operating room and animal organs from food-processing plants. In vivo models are performed in an approve...
