CLE has been shown to be useful for distinguishing benign andmalignant lesions and has been widely used in many digestive diseases. In ourstudy, we used CLE for the first time to examine the morphology of cholesterolpolyps as well as the different parts of normal gallbladder mucosa.CASE SUMMARY A 57-year-old woman was diagnosed by ultrasound with a polyp of 21 mm in thegallbladder wall. She consented to polyp removal by laparoscopic choledochoscopy.During laparoscopic cholecystectomy combined with choledochoscopicpolyp resection, CLE was used to observe the morphology of the polyp surfacecells. The appearance of the mucosa and microvessels in various parts of thegallbladder were also observed under CLE. Through comparison betweenpostoperative pathology and intraoperative CLE diagnosis, the reliability ofintraoperative CLE diagnosis was confirmed. CLE is a reliable method to examineliving cell pathology during cholecystectomy. Based on our practice, CLE shouldbe prioritized in the diagnosis of gallbladder polyps.CONCLUSION Compared with traditional histological examination, CLE has several advantages.We believe that CLE has great potential in this field.展开更多
