Abstract

Background: A new single-port device (FSIS-Flexible-Single-Incision-Surgery) is presented. This new platform has three working channels, two for rigid instruments and one for the flexible endoscope. The channel for flexible instruments offers a pneumatic sealing to avoid the air’s leak of the cavity (abdomen, rectum, and vagina). In this study the preclinical data are shown testing the feasibility and safety for laparo-endoscopic instruments.Methods: Experimental evaluation of feasibility and safety in two stages. In the first stage a working channel with pneumatic sealing was tested in simulators to use a flexible endoscope. In the second stage (animal model) the single incision device that makes possible to use laparoscopic instruments and flexible endoscopes was tested. The measured variables were: time of the procedure, CO2 employed, adverse intraoperative events, grip’s losing, losing of pneumatic sealing, feasibility and safety of the procedure for the surgeon.Results: The hysterectomy and double adnexectomy was done with a median time of 7.1 minutes. The median of the CO2 consumption was 32.5 litres. Only in one case (16.6%) the surgeon had problems with the abdominal navigation of the endoscope that was easily solved. The grip’s lose wasn’t a major problem. The median size of the skin incision was 5.4 cm. The median surgeon’ score for the feasibility was 10 and for the safety were 9.6.Conclusion: The surgeons considered that the use of the device was very feasible and safe. The FSISdevice is a universal platform for Single-Incision-Surgery for surgeons and gastroenterologists and for abdominal, rectal and vaginal access.
