Objective: Cervical excision procedures are essential to the care of cervical dysplasia and malignancy. We sought to determine whether learner involvement in cervical excision procedures affects the quality of excision specimen.
Materials and methods: A retrospective cohort study of cervical cancer patients diagnosed from July 1, 2000, to July 1, 2015, was performed. We included patients who had (1) a cervical excision procedure, either loop electrosurgical excision procedure or cold knife cone, and (2) pathologic information available. Primary outcome was the margin status of the specimen; secondary outcome was the size of the excision specimen including both width and depth. The exposure of interest was trainee participation, defined as resident physicians under the supervision of either a gynecologist or gynecologic oncologist. Descriptive statistics and general linear models were used for analysis.
Results: Ninety-four patients were identified. Overall, 58% (n = 54) of procedures were performed with trainee involvement. There was no difference in age, body mass index, or specimen width between trainee-performed and nontrainee-performed excisions. There was no significant difference in the status of margins with or without a trainee [44/57 (77%) and 29/37 (78%), respectively, p = .89]. There was a statistically significant difference in median specimen depth between trainee-performed and nontrainee-performed cases (15.4 mm vs 12 mm, p < .02). When adjusting for age, body mass index, excision type, indication, presence of trainee, and type of supervising physician, only the indication and type of excision were associated with greater depth of excision, (p < .01).
Conclusions: Trainee involvement in cervical excision procedures does not alter the quality of excision specimen.
