Power morcellation for women undergoing laparoscopic supracervical hysterectomy - safety of procedure and clinical experience from 426 cases.

OBJECTIVES: Minimally invasive gynaecological surgeries are performed for several malignant and nonmalignant indications. The aim of our study was to evaluate the rate of unexpected malignancies among women who underwent laparoscopical supracervical hysterectomy (LASH) with power morcellation.

MATERIAL AND METHODS: The retrospective analysis included clinical data of 426 consecutive female patients who underwent LASH with power morcellation due to presumed benign disorders (78.4% - symptomatic uterine fibromas, 12.7% - abnormal uterine bleeding, 8.9% - suspicion of uterine adenomyosis) between January 2011 and December 2015. Pre-malignant or malignant preoperative abnormalities in the cervix and the uterine corpus were contraindications for LASH.

RESULTS: The unexpected malignancies were found in four patients from study group: one ovarian cancer located on the inner part of simple ovarian cyst and 3 endometrial carcinomas (0.9%) were documented. All these patients underwent abdominal reoperations and no histological abnormalities were detected in the extirpated cervix and adnexa.

CONCLUSIONS: The incidence of unintended endometrial carcinoma in morcellated uterus after LASH was relatively small. However, careful pre-operative counseling should be undertaken in order to exclude the possibility of any malignant disease in uteri among women scheduled to power morcellation.
