Validation of the Animal Tissue Model for Laparoscopic Salpingectomy Training

Purpose: To gather validity evidence for a laparoscopic salpingectomy model developed for resident training.

Background: Laparoscopic salpingectomy is a milestone procedure for gynecologic trainees and is commonly performed in the management of ectopic pregnancies. Opportunities to practice the use of electrosurgical devices prior to the operating room can be limited. An animal tissue model was developed and previously piloted at our institution for this purpose, and was modified to include a pelvic sidewall and ovaries.

Methods: 25 simulations of laparoscopic salpingectomy were performed by 14 trainees (5 PGY-1, 4 PGY-2, 1 PGY-3, 4 PGY-4).  For analysis purposes the PGY-3 and PGY-4 trainees were combined.  Each trainee received scripted instructions and reviewed a video with proper technique beforehand. These recordings were evaluated by 2 blinded gynecologic surgeons using the Global Operative Assessment of Laparoscopic Skills (GOALS) and Objective Structured Assessment of Laparoscopic Salpingectomy (OSA-LS).

Results: There was good agreement between the graders with intraclass correlation coefficients of 0.63 and 0.79, respectively, for GOALS and OSA-LS.   The mean GOALS score increased with experience (10, 13.2, and 15.5 for PGY-1, PGY-2, and PGY-3/4, respectively) and was significantly different between PGY-1 and PGY-3/4 (two-sample t-test, p=0.004). The mean OSA-LS score increased with experience (8.9, 14.2, and 16.2 for PGY-1, PGY-2, and PGY-3/4) and was significantly different between PGY-1 and PGY-2 (p=0.006) and between PGY-1 and PGY-3/4 (p< 0.001).

Discussions: This training model and rubrics differentiated experienced and novice trainees and could be used to establish a preoperative competency benchmark.
