BACKGROUND: The aim of this study was to determine if uterine dimensions on preoperative imaging are associated with route of contained morcellation during laparoscopic hysterectomy.
METHODS: This is a prospective cohort study of patients undergoing laparoscopic hysterectomy and requiring morcellation for specimen extraction from March 2017 through August 2019. A contained extraction system was inserted and manual morcellation was performed vaginally, abdominally, or via a combination of both methods in cases of failed vaginal extraction.
RESULTS: A total of 47 patients were treated. Median age was 47 (range 38-70). Morcellation was performed vaginally for 29 patients (61.7%), abdominally for 13 patients (27.7%), and via combined approach for 5 patients (10.6%). The combined group had the highest frequency of patients who were black (vaginal: 24%, abdominal: 31%, combined: 100%; P=0.005), the longest median total operating time (vaginal: 167 minutes, abdominal: 183 minutes, combined: 268 minutes; P=0.006) and the longest median time of uterine morcellation (vaginal: 14 minutes, abdominal: 37 minutes, combined: 85 minutes; P<0.001). There was strong evidence of a positive correlation with time of uterine morcellation for both largest uterine diameter (Spearman’s r: 0.62, P<0.001) and uterine volume (Spearman’s r: 0.70, P<0.001). These associations remained consistent after multivariable linear regression models that were adjusted for route of morcellation, hysterectomy type, and BMI (both P<0.001).
CONCLUSIONS: Larger uterine dimensions are associated with increased total operating and morcellation times. Uterine size and volume on preoperative imaging were not associated with route of morcellation, but there was a trend towards failed vaginal extraction when uterine dimensions exceeded 16 centimeters.
