Development and assessment of a loop ligation simulator for laparoscopic appendectomy.

OBJECTIVE: Loop ligation of the appendix is a challenging surgical skill and well suited to be trained in a simulator. We aimed to develop an affordable and easy-to-build simulator and test its training effect.

DESIGN AND PARTICIPANTS: Different materials were tested, and the best training modality was identified by researching the literature. The developed simulator training was tested on 20 surgical novices.

RESULTS: A video was produced including an instruction on how to build the simulator and a step-by-step tuition on how to ligate the appendix. The Peyton approach was utilized to guide learners. Training with the simulator leads to reliable skill acquisition. All participants improved significantly in completing the task successfully during the structured learning.

CONCLUSION: We succeeded in developing a simulator for loop ligation of the appendix during laparoscopic appendectomy. Participants significantly improve in handling the loops. The transferability of the skill learned during simulation to the operating room will be subject of a follow-up study.
