The primary objective of this study is to evaluate the usefulness of the CADISS System for dissection of the Calot’s triangle or gallbladder during the detachment of pathological tissues in laparoscopic cholecystectomy.


A prospective, multi-sites, open label, single cohort clinical trial on 15 patients evaluating the use of CADISS System to facilitate dissection of Calot’s triangle and gallbladder in patients who undergo a cholecystectomy in case of acute cholecystitis. 


This study in a limited number of patients suggests that chemically assisted dissection seemed to facilitate and improve safety of dissection in acute cholecystitis. Topical deposition of a mesna solution helps reveal the anatomical planes and may reduce the use of non-selective cutting instruments such as electric knives. Benefits appeared independent from the severity grade of cholecystitis and from the delay in performing the surgery. Further studies should be conducted to confirm our preliminary results.
