Feasibility of a Combined Percutaneous Laparoscopic Three-Millimeter Device

摘要

Background and Objectives: Needlescopic 3-mm instruments induce minimal trauma and produce excellent cosmetic results. A combination of a 3-mm abdominal wall incision and a 5-mm instrument in the abdominal cavity would combine the beneficial features of these two different sizes.Methods: The Percutaneous Surgical System (PSS) (Ethi-con EndoSurgery, Galway, Ireland) is a new instrument consisting of a 3-mm shaft that is introduced percutane-ously into the abdominal cavity. Through a 5-mm trocar, a loader with a 5-mm attachment such as a Maryland dissector is introduced. The attachment is connected to the shaft, and the loader is removed from the abdomen. The feasibility of this device was evaluated retrospectively in 3 Swedish hospitals between January and September 2012.
