Brief description/objective

BACKGROUND
AirSealTM is a novel class of valve-free insufflation system that enables a stable pneumoperitoneum with continuous smoke evacuation and carbon dioxide (CO2) recirculation during laparoscopic surgery. Comparison data to standard CO2 pressure pneumoperitoneum insufflators is scarce. The aim of this study is to evaluate the potential advantages of AirSealTM compared to a standard CO2 insufflator.

METHODS
This is a single center randomized controlled trial comparing elective laparoscopic cholecystectomy, colorectal surgery and hernia repair with AirSealTM (group A) versus a standard CO2 pressure insufflator (group S). Patients are randomized using a web-based central randomization and registration system. Primary outcome measures will be operative time and level of postoperative shoulder pain by using the visual analog score (VAS). Secondary outcomes include the evaluation of immunological values through blood tests, anesthesiological parameters, surgical side effects and length of hospital stay. Taking into account an expected dropout rate of 5%, the total number of patients is 182 (n = 91 per group). All tests will be two-sided with a confidence level of 95% (P <0.05).

DISCUSSION
The duration of an operation is an important factor in reducing the patient's exposure to CO2 pneumoperitoneum and its adverse consequences. This trial will help to evaluate if the announced advantages of AirSealTM, such as clear sight of the operative site and an exceptionally stable working environment, will facilitate the course of selected procedures and influence operation time and patients clinical outcome.Trial registration: ClinicalTrials.gov NCT01740011, registered 23 November 2012.
