The Endo Bag single-use specimen container is supplied sterile in a dispensing tube for ease of insertion through a standard 10 mm, 11 mm, or 12 mm trocar cannula. Currently marketed specimen retrieval bags differ in their size (i.e., diameter of the bag) and in the technique employed to open and deploy the bag. The most commonly used specimen bags in gynecology range from 10 to 15 cm in diameter, and allow for easy removal of most adnexal masses. The 10 cm bags usually require a 10 mm laparoscopic port for introduction into the abdomen, which may be placed in the umbilicus or in the lower abdomen. The advantage of using a 10 cm umbilical port for introduction of the bag instead of a lower abdominal port is that the former usually does not require fascial closure. The 15 cm specimen bag usually requires a 12 mm port for introduction into the pelvic, necessitating closure of the fascia layer to avoid port-site hernia. Specimen retrieval bags also differ in their opening technique. Some specimen bags have the ability to open automatically after introduction into the abdomen, while others require manual opening by two graspers holding the bag edges. The bags with automatic opening are usually easier to use, but often more expensive than the bags with manual opening an automatically opening bag (Endocatch, manufactured by Covidien, Mansfield, MA, USA), respectively. All bags are manufactured for single use. We have found that the specimen bag with a 10-cm diameter and manual opening is suitable for most adnexal surgeries, obviating the need to use the more expensive bags with automatic opening Some authors have described the use of home-made specimen bags, such as a surgical glove or a zipper storage bag, which are cheaper than the manufactured bags
