title: Lap simulator, animal studies, and the Laptent. Bridging the gap between open and laparoscopic surgery.
abstract: In an effort to ensure proper training and to establish a routine amongst the surgical team right from the start, we began practicing laparoscopic techniques with the lap simulator. After having acquainted ourselves with the fundamentals of this minimal-invasive method, we applied our newfound experience to the animal model. Even though the subsequent studies with pigs were the best learning model in which to practice different surgical techniques--e.g., ureter clipping and renal vessel triple stapling with the Endo-GIA--various problems can arise in a true clinical situation since anatomical diversity exists between an animal and human situs. We found that a compromise could be reached by simulating laparoscopic conditions during open surgery without endangering the safety of the patient during any point of the operation. After open surgical exposure of the Gerota fascia was carried out, the operative site was completely covered with the Laptent. From this moment on, all operative steps were performed with laparoscopic instruments under continuous video monitoring. Our step-by-step training program has exposed the surgeon and OR staff to the complexity of this new surgical technique. The use of the Laptent has successfully bridged the gap between open and laparoscopic surgery. Most important of all, those surgical centers without access to extensive experimental studies will realize that Laptent-assisted surgery can be of benefit and facilitate the clinical introduction of this minimal-invasive method.
