Prognostic Factors for Morcellation During Vaginal Hysterectomy

Area of Science:

• Gynecologic Surgery
• Surgical Techniques
• Urogynecology

Background:

• Vaginal hysterectomy is a common gynecologic procedure.
• Cold-knife morcellation is a technique used to facilitate uterine removal during vaginal hysterectomy.
• Predictors for the utilization of morcellation during vaginal hysterectomy are not well-established.

Purpose of the Study:

• To identify prognostic factors associated with the use of cold-knife morcellation during vaginal hysterectomy.
• To understand patient and uterine characteristics that influence the decision for morcellation.

Main Methods:

• Retrospective cohort study of patients undergoing vaginal hysterectomy between 2009 and 2014.
• Primary outcome: utilization of uncontained vaginal morcellation via cold-knife wedge resection.
• Multivariate logistic regression analysis to identify significant predictors.

Main Results:

• Younger age, non-Caucasian race, American Society of Anesthesiologists class 1 or 2, lower parity, fewer prior vaginal deliveries, absence of prolapse, presence of leiomyoma, and enlarged uterus were associated with increased likelihood of morcellation.
• Multivariate analysis identified absence of prolapse (aOR 3.87), leiomyoma (aOR 2.77), and larger uterine weight (aOR 7.25) as increasing the likelihood of morcellation.
• Prior vaginal delivery was associated with a decreased likelihood of morcellation (aOR 0.79).

Conclusions:

• Vaginal hysterectomy with morcellation is associated with specific patient and uterine factors.
• Key predictors include absence of prior vaginal delivery, absence of prolapse, presence of leiomyoma, and larger uterine size.
• These findings can aid in surgical planning and patient counseling.
