Clinical Trial Summary

This trial is designed as a prospective, multi-center, single-blind, parallel, randomized controlled clinical trial. The trial will be carried out in 5 centers, involving 220 subjects as estimated who will be divided into the test group or control group randomly on an equal basis (each group includes 110 subjects). This trial will be carried out in 4 stages, including the screening period, random grouping, operation date and follow-up period. In the screening period, the informed consent forms are collected and inclusion and exclusion criteria are verified; after that, the accepted subjects will be randomly divided into the control group or test group; on the operation date, the operation is carried out using the device; safety follow-up visit is carried out during the follow-up period.


Clinical Trial Description

The prospective, multi-center, single-blind, parallel, randomized controlled non-inferiority trial design is adopted to evaluate the safety and effectiveness of the real-time endoscopic near infrared fluorescence image provided by the LED light source system for endoscope by evaluating at least one main extrahepatic bile duct (common bile duct and ductuli hepaticus communis). The trial will be carried out in 5 centers, with the competitive grouping mode adopted. Totally 220 patients to receive laparoscopic cholecystectomy will be involved (110 patients for each of the control group and the test group). The subjects, after signing the informed consent form approved by the Ethics Committee, will be screened by the investigators. Qualified subjects who meet all the inclusion criteria and do not meet any of the exclusion criteria will be randomly divided into the control group or the test group. For the subjects in the control group, the Pinpoint Endoscopic Fluorescence Imaging System commercially available will be used for operation. For subjects of the test group, the LED light source system for endoscope will be used for operation. On the operation date, investigators will evaluate the display performance of the device by judging whether at least one main extrahepatic bile duct (common bile duct and ductuli hepaticus communis) is displayed. During the follow-up period, the investigators will evaluate the safety of the device based on the results of vital signs, physical examination, blood routine examination, routine urine examination, blood biochemistry and 12-lead ECG. ;
