Definitions

  • Mature cystic teratomas, or dermoids are the most common benign ovarian neoplasm. Laparoscopic cystectomy rather than oophorectomy is recommended removal of these cysts for the majority of pre-menopausal women. Rupture of the dermoid occurs approximately 80% of the time during cystectomy. Upon rupture, the dermoid spills contents such as grease, fat, and hair into the peritoneal cavity. Although most patients will have no significant consequences of rupture, there are a number of reports of chemical and granulomatous peritonitis resulting from the spill, some with very significant morbidity including bowel obstruction and need for repeated surgery and prolonged hospitalization. Currently, cystectomies are performed over a“bag on a stick” to capture any spill that occurs, but this requires an extra port site as well as an assistant to hold the bag during the surgery.

Abstract

L'invention concerne un dispositif comprenant un sac de récupération d'échantillon autonome. L'invention concerne également un procédé d'utilisation d'un sac autonome pendant une kystectomie, le sac étant d'abord fixé autour du mésovarium. La bouche du sac est ensuite positionnée pour encercler l'ovaire, de telle sorte qu'une kystectomie peut être effectuée à l'intérieur du sac pour capturer tout débordement qui se produit. Les dispositifs, procédés et systèmes de l'invention évitent le besoin traditionnel de ports chirurgicaux supplémentaires ou d'un assistant supplémentaire lors de la réalisation d'une kystectomie à l'intérieur d'un sac de récupération d'échantillon.
