摘　　要：Confocal laser endomicroscopy permits in-vivo microscopy evaluation during endoscopy procedures. It can be used in all the parts of the gastrointestinal tract and includes: Esophagus,stomach,small bowel,colon,biliary tract through and endoscopic retrograde cholangiopancreatography and pancreas through needles during endoscopic ultrasound procedures. Many researches demonstrated a high correlation of results between confocal laser endomicroscopy and histopathology in the diagnosis of gastrointestinal lesions; with accuracy in about 86% to 96%. Moreover,in spite that histopathology remains the gold-standard technique for final diagnosis of any diseases; a considerable number of misdiagnosis rate could be present due to many factors such as interpretation mistakes,biopsy site inaccuracy,or number of biopsies. Theoretically; with the diagnostic accuracy rates of confocal laser endomicroscopy could help in a daily practice to improve diagnosis and treatment management of the patients. However,it is still not routinely used in the clinical practice due to many factors such as cost of the procedure,lack of codification and reimbursement in some countries,absence of standard of care indications,availability,physician imageinterpretation training,medico-legal problems,and the role of the pathologist. These limitations are relative,and solutions could be found based on new researches focused to solve these barriers.Confocal laser endomicroscopy permits in-vivo microscopy evaluation during endoscopy procedures.
