Abstract

Introduction. Postmortem changes in pigskin made it difficult to be manipulated as a model for advanced technique in surgery training. The use of bromelain enzyme on these pigskins could be an alternative way to obtain the ideal surgery training model. Method. Thirty-five pigskin-blocks (10×15cm) was divided evenly into seven groups consisted of six groups of different bromelain enzyme treatment (4g/20min, 4g/40min, 8g/20min, 8g/40min, 12g/20min, 12g/40min) and one group of control. Then five chief-plastic-surgery-residents blindly assessed and scored each pigskin and compared its likeliness to the back of human skin. The scores were then analyzed with an interrater reliability test using SPSS 16.0. Results. All five assessors unanimously chose the 8g/40min group as the most likeliness to the back of human skin. The highest score was obtained for piercing the needle into the pigskin (8.4 ± 0.54). Conclusion: The appliance of 8 grams bromelain enzyme in 10×15cm pigskin blocks for 40 minutes was proven to be an ideal surgery training model comparing the back of human skin, especially for tangential excision.

Abstract

Introduction. The laparoscopy procedure still has an ergonomic burden that can increase the risk of musculoskeletal injury, especially in the upper extremity. Furthermore, the risk is compounded in laparoscopic training as the trainees have to repeat the same movements many times to achieve competencies. This study revealed the relation between the position and the risk of musculoskeletal injury in laparoscopy training. Methods. A cross-sectional study on nine subjects was conducted during laparoscopy training. By fixing the table height at 77 cm, we measured the operator height and upper extremity positions to relate them to their VAS and DASH scores. Results. The overall ratio of table height to subject height was Conclusions. There is a risk of upper extremity musculoskeletal injury without disabilities. The pain produced by laparoscopy activity has shown to be mild and needs no medication. The wrist position is considered the highest risk of initiating the upper extremity injury.
