Introduction: Unprotected power morcellation can lead to a spread of previously undiagnosed malignancy. We present a new containment bag with two closable trocar insertion sites to reduce this risk. This pilot study was designed to assess the feasibility of this device under everyday conditions.
Material and methods: The containment bag was used in ten laparoscopic supracervical hysterectomies. We evaluated time requirement for bag insertion into the abdominal cavity and in-bag morcellation. A 2000 ml polyurethane morcellation bag was used for all interventions. All surgeries were carried out in a three-trocar setting.
Results: We carried out ten supracervical hysterectomies. No intraoperative complications and no bag ruptures occurred. The meantime requirement to insert the bag and prepare the specimen for morcellation was 10.5 min (range, 7-19 min). The mean specimen weight was 191.9 g (range, 32-710 g). Mean morcellation time was 10.5 min (range, 3-28 min), mean weight of remaining tissue and fluid in the bag after morcellation was 12.1 g (range, 7-19 g).
Conclusions: The presented data demonstrate that the endobag can be successfully applied in the clinical routine. Further studies are required to evaluate additional characteristics, such as individual learning curve and time requirements.
