Abstract
BackgroundArtiSential, a new articulating laparoscopic instruments, addresses the limited movement associated with conventional laparoscopic instruments. This study was conducted to assess the clinical effectiveness of ArtiSential in detailed steps of various renal surgery.MethodsThis study was approved by the Institutional Review Board of our institution and registered on the Clinical Research Information Service site of the Korea Disease Control and Prevention Agency. Participants meeting all inclusion and exclusion criteria were included in the clinical trial and underwent renal surgery. The clinical effectiveness of ArtiSential was assessed in terms of the feasibility and objective and subjective parameters across 9 detailed steps.ResultsOf the 15 potential candidates enrolled from October 2021 to November 2021, 1 patient dropped out due to anaphylaxis from an anesthetic agent, and 14 patients underwent laparoscopic surgery using ArtiSential. Of the 14 patients, 2 patients were converted to laparoscopic surgery using straight-shaped instruments due to the ischemia time exceeding 30 min, and 1 patient due to excessive bleeding. The feasibility for most steps was more than 90%, except the renorrhaphy step. The median total operation time and ischemia time were 161 and 23 min, respectively. The median estimated blood loss was 58.5 mL. Two cases of venous injury occurred during renal pedicle dissection step. The accuracy of the procedure judged by reviewers and usability judged by the operator were acceptable in all steps. The surgeon’s quantitatively measured stress score was the highest during renorrhaphy step.ConclusionsLaparoscopic surgery using ArtiSential is feasible for most steps except the renorrhaphy step. The difficulty of performing renorrhaphy is attributed to prolonged ischemia time, which could be addressed by overcoming the learning curve.Trial registrationClinical Research Information Service site of the Korea Disease Control and Prevention Agency, KCT0006532.
