Abstract:
Objective To evaluate the feasibility and safety of peroral direct cholangioscopy (PDCS) by freehand intubation using routine straight-view endoscope for diagnosis and therapy of biliary diseases.Methods Patients with bile duct dilation underwent standard ERCP and native papilla was dilated using EST and/or endoscopic papillary large balloon dilation,according to the size of the papilla.Then peroral direct cholangioscopy was performed by freehand intubation using routine straight-view endoscope.General data of patients,procedure of ERCP,diagnosis of PDCS and complications were recorded.Results A total of 5 patients underwent PDCS.Indications included common bile duct stones (n =2),intraductal papillary neoplasm of bile buct (n =2) and benign biliary stricture after removable metal stent placement (n =1).The diameter of common bile duct ranges from 1.2 cm to 2.4 cm.EST or/and EPLBD was required in 3/5 patients to facilitate PDCS.Freehand PDCS intubation of the bile duct was successful in all procedures (1 case into distal common bile duct,4 cases into proximal common bile duct).Complications were cholangitis managed with intavenous antibiotics (n =1).No procedure related death occurred.Conclusion Freehand PDCS is technically feasible and safe,and may be clinically useful for diagnostic and therapeutic purposes in managing select biliary tract diseases.
