Feasibility of myomatous tissue extraction in laparoscopic surgery by contained in - bag morcellation: A retrospective single arm study.

PURPOSE

To evaluate the feasibility of using contained endobags (Morsafe) in the retrieval of the specimen during laparoscopic surgeries in presumably benign myomatous pathology.

MATERIAL AND METHODS

We conducted a retrospective single center case - control study on 239 patients, between 01.05.2014 and 31.12.2017 for uterine myomata, presumed to be benign. The analyzed parameters were the method for contained specimen retrieval, the time of bag manipulation, practicability of action and the perioperative complications rate. The present work has been reported in accordance with the STROCSS criteria and guidelines [1].

RESULTS

the main laparoscopic interventions were myomectomy (n = 148 cases) and LASH (laparoscopic supracervical hysterectomy) (n = 68 cases), LASH with bilateral salpingectomy (n = 7), LASH and bilateral adnexectomy (n = 3), LTH (laparoscopic total hysterectomy) (n = 3), LTH and bilateral adnexectomy (n = 1), radical LTH with lymphonodectomy (n = 2), LTH with bilateral salpingectomy (n = 1) and adenomyomectomy (n = 6). In 3 cases using contained closed bags, there was an evidence of malignancy in the pathological sections: leiomyosarcoma (n = 1) and endometrial carcinoma (n = 2). There were no adverse events and no intra - or postoperative bag - induced complications. Regarding the intraoperative duration, the time of bag introduction was about 7 min, and morcellation approximately 12 min.

CONCLUSION

in - bag morcellation through endobag (Morsafe) proved to be a safe laparoscopic method in retrieval of myomatous tissue, potentially reducing the risk of dissemination and thereby improving the patients' safety avoiding spreading of benign disease and malignancy, but preserving the benefits of minimally invasive surgery. The advantages concerned not only the operating time and costs, but also the safety aspects in case of malignancy. As the system can help to reduce risk of cell dissemination it could also reduce the risk in case of occult malignancy.
