Development of a Low-Fidelity Laparoscopic Sacrocolpopexy Simulation Model and Evaluation of Curriculum.

OBJECTIVES

Minimally invasive sacrocolpopexy (SCP) is a compelling surgical procedure that requires advanced laparoscopic suturing and dissection skills and knowledge of pelvic retroperitoneal anatomy. The aim of this study was to develop a low-cost laparoscopic SCP model and educational curriculum to improve dissection and suturing skills along with anatomic knowledge to avoid complications.

METHODS

The pelvic SCP model was developed with easily available material that was placed on the commercial pelvic bone model to construct a vagina, major vessels, ureter, peritoneum, and areolar tissue. A comprehensive curriculum encompassing didactic and technical skills components on the pelvic model was used to teach laparoscopic SCP. Participants completed precurriculum and postcurriculum multiple-choice questionnaires to evaluate the didactic component. A modified Objective Structured Assessment of Technical Skills (OSATS) tool was used to measure technical skills before and after technical skills curriculum.

RESULTS

Among the 10 senior residents, 6 (60%) were studying at their fourth postgraduate year, and 3 (30%) were studying at their third postgraduate year. Postcurriculum test scores (14.5 vs 10.6) for assessment of cognitive knowledge were significantly improved (P < 0.001). The median postcurriculum OSATS scores (26.5; range, 18-30) were significantly improved (P = 0.005). Laparoscopic SCP OSATS scores increased from median 21 to median 26.5 after cognitive and technical curriculum, showing a 21.4% improvement. The majority (70%) of residents believed that the SCP model would be useful to enhance skills acquisition before performing the skill in the operating room.

CONCLUSIONS

A low-fidelity laparoscopic SCP curriculum showed improvement in cognitive knowledge and technical skills.
