Endobag extractor to remove masses during laparoscopy.

Abstract

Intra-abdominal masses are removed during laparoscopy using different types of endobags. However, in many cases the specimens are larger than the trocar or the incision in the abdomen, with a potential risk of endobag rupture. We developed an instrument to facilitate extraction of an endobag during laparoscopy without the need for a conventional minilaparotomy. The endobag extractor has three removable diverging blades that symmetrically enlarge the operative canal in the abdominal wall if spread after sharp extension of the skin incision. The full endobag can be drawn through the canal without the risk of endobag rupture because the size of the canal can be individualized, building a funnel. We removed various kinds of ovarian tumors, specimens from salpingo-oophorectomies, and other specimens in 22 cases. This new instrument allows easy removal of surgical specimens during laparoscopy without conventional minilaparotomy, regardless of the type of endobag used. We believe this instrument lessens the risk of endobag rupture.
