摘　　要：BACKGROUND To date,endoscopic retrograde cholangiopancreatography has become a wellestablished treatment for common bile duct(CBD)stones.However,it is not suitable for some special patients,such as pregnant women,children or those who cannot stop taking anti-coagulation/anti-platelet agents because of radiation injury and the risk of postoperative bleeding resulting from endoscopic sphincterotomy.To overcome these two problems,this study introduced cholangioscopy-assisted extraction through a novel papillary support for small-calibre and sediment-like CBD stones.AIM To assess the feasibility and safety of cholangioscopy-assisted extraction through a novel papillary support(CEPTS)for small-calibre and sediment-like common bile duct(CBD)stones.METHODS This Retrospective study was approved by the Ethics Committee of the Chinese PLA General Hospital.We designed a covered single dumbbell-style papillary support between 2021 and 2022.Between July 2022 and September 2022,7 consecutive patients with small-calibre(cross diameter≤1.0 cm)or sediment-like CBD stones underwent CETPS procedures in our center.The clinical characteristics and treatment outcomes of these 7 patients were extracted from a prospectively collected database.And the related data were analyzed.Informed consent was obtained from all participating patients.RESULTS A total of 2 patients had yellow sediment-like CBD stones,and aspiration extraction was performed after the insertion of papillary support.Of the 5 patients with clumpy CBD stones(0.4-1.0 cm),2 underwent basket extraction under direct vision for a single stone(0.5-1.0 cm,black and black grey),1 underwent balloon plus aspiration extraction under direct vision for 5 stones(0.4-0.6 cm,brown),and 2 underwent aspiration extraction only for a single stone(0.5-0.6 cm,yellow,none).Technical success,namely,no residual stones in the CBD or left and right hepatic ducts,was achieved in all 7 cases(100%).The median operating time was 45.0 minutes(range 13.0–87.0 minutes).Postoperative pancreatitis(PEP)oc
