Fishing-rod-type abdominal wall lifter for gasless laparoscopic surgery.

We have designed a new abdominal wall lifter for gasless laparoscopic surgery which consists of stainless steel rods and iron lifters. They elevate the abdominal wall up like a dome-type camping tent, which does not disturb any manipulation of scope or X-ray camera. We received a good view of the peritoneal cavity without CO2 gas insufflation in ten patients with cholecystitis. This will be helpful for general laparoscopic surgery or laparoscopic assisted surgery with the use of conventional forceps or extracorporeal suturing through a valveless trocar.
