A cholecystoscope is a medical instrument used to examine the inside of the gallbladder. It is a thin, tube-like device equipped with a light and camera, allowing doctors to visualize the gallbladder's condition. This tool is often used during a procedure called cholecystoscopy, which helps diagnose issues such as gallstones or inflammation. The cholecystoscope can be inserted through small incisions in the abdomen, making it a minimally invasive option for patients. By providing clear images, it assists healthcare professionals in determining the best course of treatment for gallbladder-related problems, enhancing patient care and outcomes.
