Devices for hand-assisted laparoscopic surgery.

A number of tools have been introduced to make laparoscopy easier. Some, such as 3D video systems, are interesting, and may add a modicum of benefit in some situations, but overall, have not had substantial impact. Others, such as robotic surgery, clearly have great potential, but are simply too expensive for widespread use. A few, such as the argon beam coagulator, are helpful only in particular situations. One technique has lived up to its billing and moreover, can be applied in almost any laparoscopic procedure, it is cost effective and actually does make laparoscopy easier. Hand-assisted laparoscopic surgery is a useful adjunct to the laparoscopic surgeon, and should be considered by all interested in this endeavor. This review summarizes the current hand-assistance devices and their use.
