Predictive Factors for Morcellation during Total Laparoscopic Hysterectomy: A Cohort Study

Area of Science:

• Minimally Invasive Gynecologic Surgery
• Surgical Oncology
• Diagnostic Imaging

Background:

• Total laparoscopic hysterectomy (TLH) is a common procedure for benign gynecologic conditions.
• Morcellation, often performed during TLH, facilitates uterine removal but carries potential risks.
• Predicting the need for morcellation is crucial for surgical planning and patient counseling.

Purpose of the Study:

• To identify predictors of morcellation during total laparoscopic hysterectomy (TLH).
• To evaluate the utility of preoperative imaging in assessing factors influencing morcellation.
• To improve surgical decision-making for hysterectomy procedures.

Main Methods:

• Retrospective cohort study of 252 women undergoing TLH for benign gynecologic pathology.
• Analysis of preoperative ultrasound or MRI data to estimate uterine weight and characteristics.
• Multivariate logistic regression to identify significant predictors of morcellation.

Main Results:

• Uterine weight estimated by preoperative imaging is a significant predictor of morcellation (OR 3.7).
• The presence of at least one leiomyoma (OR 4.1) and leiomyoma size ≥5 cm (OR 8.6) also predict the need for morcellation.
• Women with uterine weight <250 grams rarely required morcellation (5%), while those >500 grams always did (100%).

Conclusions:

• Preoperative uterine weight estimation via imaging is a key predictor for morcellation during TLH.
• Uterine leiomyoma characteristics, including number and size, are significant predictors of morcellation.
• These findings aid in optimizing surgical planning and patient selection for TLH with or without morcellation.
