简要总结
Acute cholecystitis is the most common complication of cholelithiasis. Acute cholecystitis is inflammation of the gallbladder that develops over hours, usually due to an obstruction of the cystic duct by a gallstone. Removal of the gallbladder (Cholecystectomy) is the only definitive treatment for acute cholecystitis, with laparoscopic cholecystectomy (LC) considered the gold standard. Serious complications that may occur with laparoscopic cholecystectomy, including bile duct injury, bile leaks, bleeding, and bowel injury, result in part from the anatomy, disease related pathology and structural misidentification due to inflammatory process (Gupta 2019).
The CADISS® System, Chemically Assisted mechanical DISSection, is intended for the selective detachment of pathological tissue layers and/or fibrotic tissues in various surgical procedures without using cutting instruments. It is based on the property of the drug mesna (Sodium 2-mercaptoethane sulfonate) to cleave the disulfide bonds responsible for the adherence of pathological tissues and for the strength of fibrosis. This study is a prospective, multi-sites, open label, single cohort clinical trial evaluating the use of CADISS® system to facilitate dissection of severe adhesions in cholecystectomy and to allow better identification of different structure.
